I see that the paper Gloria Ayob and I have written on psychopathy for Theoretical Medicine and Bioethics is now available from the journal's website. It is here.
The abstract runs:
Psychopathy is often used to settle disputes about the nature of moral judgment. The “trolley problem” is a familiar scenario in which psychopathy is used as a test case. Where a convergence in response to the trolley problem is registered between psychopathic subjects and non-psychopathic (normal) subjects, it is assumed that this convergence indicates that the capacity for making moral judgments is unimpaired in psychopathy. This, in turn, is taken to have implications for the dispute between motivation internalists and motivation externalists, for instance. In what follows, we want to do two things: firstly, we set out to question the assumption that convergence is informative of the capacity for moral judgment in psychopathy. Next, we consider a distinct feature of psychopathy which we think provides strong grounds for holding that the capacity for moral judgment is seriously impaired in psychopathic subjects. The feature in question is the psychopathic subject’s inability to make sincere apologies. Our central claim will be this: convergence in response to trolley problems does not tell us very much about the psychopathic subject’s capacity to make moral judgments, but his inability to make sincere apologies does provide us with strong grounds for holding that this capacity is seriously impaired in psychopathy.

On democratically selecting research ideas
I spent the day at a brainstorming session on mental health research at the University today (one of a series of ‘Grand Challenge’ workshops organised across a number of inter-disciplinary themes), aimed at outlining some key problems or issues that face mental healthcare and hence potential subjects for research.
It served as a good opportunity to meet another selection of researchers at the University interested in mental health, in addition to those who already are part of our Mental Health Research @ Uclan group. It was also very well attended by colleagues who work broadly in research support, meeting whom face to face is really useful. There are all sorts of tacit dimensions, especially concerning trust and collective action, which are poorly served by emails.
Four genuinely interesting topics emerged for development: the use of electronic resources and game playing in the diagnosis and data collection especially concerning motor skills of those with dementia; the possible connection between dental hygiene and dementia; the use of tasers on the mentally ill including in clinical settings; and the wellbeing of call centre workers. All of that is a positive result for the day and it was well worth attending.
But I realised that there was also a counter-intuitive effect of the selection process, perhaps because of the initial highlighting of practical concerns for mental healthcare, perhaps because we were encouraged to see what issues emerged from conversation in groups that day rather than bringing along a prepared list of topics (as I had in case such be needed) and perhaps because we were encouraged in the morning to think very broadly or laterally and with no concern for the usual issues of what is fundable, or this year's intellectual or research fashion. This was that the connection between a topic being selected, a principal investigator being interested and possible funding streams being available came only as a matter of happy contingency. In the afternoon we were rather landed with the blue skies thinking of the morning. (Cf "That's a problem for Future-Homer. Man, I don't envy that guy!")
Voting on brainstormed topics in the abstract, rather than topics proposed explicitly by individuals, meant that there was at least a chance that what emerged wasn't researchable by those present. In my group this was only avoided by narrowing down the selected topic very dramatically and pragmatically to fit one of the two academics at the table in such a way that, sadly, the resultant topic had no obvious conceptual or philosophical spin. This makes me think that useful though the day was, it wasn't really the best way coping with the contingency and chance that often underpins new research.
What would be? Thinking back I realise that much of the philosophy of mental health I have researched, whether in the end individually or with others, has emerged from or been inspired by chance conversations but I am not sure that there is any clear pattern in the nature of the conversations. (They have not usually been started with the idea of articulating a research area in mind.) But ultimately it has never been a democratic process. That others (I mean others in general, not others to me) find a topic interesting is never, in the end, enough to motivate someone else also doing it. So shared ownership cannot be engineered by a democratic day but is a rather slower matter of seeing how topics appeal to others where, on any given day, not appealing is rather more likely than appealing. The alternative seems to be akin to a high risk speed dating session where everyone has to marry someone at the end of the process.
With this in mind, I again regret the passing from academia of the post work beer.

Postscript on disjunctivism and induction
A conversation with Gloria and actually teaching a session on Hugh Mellor on induction has prompted a couple of further thoughts on what a disjunctivist
account of induction would look like.
1) What does a disjunctivist spin on McDowell’s remarks add to
their intended use as a deconstruction of Hume’s starting point for the problem
of induction?
As we would expect of a therapeutic McDowell, he himself does not
aim to solve Hume’s problem but dissolve it. Hume assumes a contrast between
unproblematic observation and problematic induction. But, McDowell argues, such
a distinction cannot be drawn because the reports of observation are always (I
want to say: always already) induction presupposing.
Consider a characteristic Humean formulation of the
predicament that is supposed to invite inductive skepticism:
It may, therefore, be a subject worthy of curiosity, to enquire what is the nature of that evidence, which assures us of any.. .matter of fact, beyond the present testimony of our senses....
Taking it seriously that what is in question is testimony of our senses, we must think in terms of something content-involving-something in which, say, colors figure as apparent properties of objects. A mere wash of chromatic sensation, not referred to a supposedly perceived environment, could not count as testimony of our senses. Now my fourth Sellarsian idea can be put like this: there cannot be a predicament in which one is receiving testimony from one's senses but has not yet taken any inductive steps. [McDowell 1995: 890-1]

Now my fourth Sellarsian idea can be put like this: there cannot be a predicament in which one is receiving testimony from one's senses but has not yet taken any inductive steps. [McDowell 1995: 890-1]
This looks like the bare bones of a transcendental argument.
Observation is possible; observation presupposes induction; so induction is
possible.
But whilst that might serve to undermine the legitimacy of a
scepticism which is differentially directed against induction but not
observation it does not shed light on how induction is possible. One might
respond to the transcendental argument that whilst one accepts that observation
stands and falls with induction, nevertheless, one is still baffled by how the
latter is possible or, to put it another way, how the inductive element of
observation – that which transforms it from a mere wash of chromatic sensation –
is possible.
Sketching a disjunctivist picture of induction helps start to address
that remaining worry. Induction is possible because one can take in,
experientailly, a future-implicating pattern of events. Observation is not just
of temporally unrelated time-slices. (That’s what Hume seems to rule out at the
start.)
2) But doesn’t the question of what we do, experientially, take
in underdetermine possible future patterns? That is, are we not in the end any better off than the Humean inductive sceptic?
To make this worry vivid requires, I think, slipping back into
the assumption that all that is really taken in experientially is a set of
time-slices with no implications for the future. But there is a related worry
which seems legitimate: Goodman’s New Riddle of Induction. On this picture,
observation reports are taken to be conceptually structured in a way which has
future implications. But there remains the challenge of justifying which
concepts are instantiated in past observations in the face of merely future
differences.
3) What kind of future-directed structure needs to be implicit in
past observations for such observations to form the basis for future predictions?
My motivation for this question stems from the contrast I have in
mind between Mellor’s blankly external factors and what I take to be internal
in a disjunctivist approach. On Mellor’s account, past observations warrant
predictions for the future in virtue of there actually being laws which link
the worldly events observed in the past and the predicted future events whether
or not the subject knows this. So the question as to the nature of this link is
left to the world: the link is whatever it is.
By contrast, on my sketch of a disjunctivist account, the nature
of the good disjunct should be ‘internal’ to the subject’s epistemic standing
and provide her with reasons for her belief. If so, it can hardly be that the
subject is only justified if she has a correct account of the natural laws by
the standards of a future physics. But what conception would be sufficient to
justify the future-directed inference? More seems to have to be loaded onto the
subject in the case of induction than in the case of object-directed perceptual
thought.
4) Isn’t there a difference between the role that enduring
objects play in securing the future implications of past observations and that
played by recurring events?

Some thoughts on Hugh Mellor's 'The Warrant of Induction'
But observations are... fallible, a fact we obscure when we
use words like ‘observe’ so that by mere definition we can’t observe what isn’t
there. So I will not use ‘observe’, ‘see’, ‘hear’, etc. in that misleading way.
When my looking to see if there are sparrows makes me believe that there are, I
shall say that I see that there are, whether there are or not. For there might
not be: our senses always can give us false beliefs and sometimes do.
Observation no more entails the truth of the beliefs it gives us than induction
does. How then can it warrant them? [Mellor 1988]
The question here is how observation warrants the truth of
the beliefs it motivates. Mellor’s answer is that causal links enable
observations to warrant beliefs because, he claims, the fact that makes a
belief true is what causes the belief to be held. (Given that this is supposed
to be the warrant observation provides, the causal connection must (I assume)
be via a suitable sensory path.)
The claim that observation isn’t
factive can now be accommodated via the further – independently plausible –
claim that causation isn’t deterministic. If causation merely raises the
chances of its effects (ie if it doesn’t have to make the chances of its
effects = 1) then thinking that one sees a sparrow can warrant a belief in
sparrows by suitably raising the chances of their being sparrows, though not to
1 and other things can also cause a belief in sparrows.
This then serves as a point of
departure for thinking about the warrant of the truth of beliefs produced by
induction. In this case, it cannot be that the facts that cause the beliefs are
the same facts that make those beliefs true because induction isn’t a kind of
direct perception of the future, for example. Rather, the facts that cause the
inductive belief are the inductive base: the premises not the conclusion of the
inductive inference. So what warrants the truth of the resultant belief in the
conclusion?
Mellor’s answer is that the warrant is
the lawlike connection between the truth of the premises and the truth of the
conclusion. Providing that the world is suitably lawlike, induction is
warranted. Hence a quotation at the start of the lecture from Frank Ramsey ‘we are all convinced by inductive arguments, and our
conviction is reasonable because the world is so constituted that inductive
arguments lead on the whole to true opinions’. But the laws need not be
deterministic to provide a warrant. They just need to raise the chances of
effects sufficiently.
Suppose, to simplify the discussion (it’s not essential),
that your inferential habits are deterministic, like your mass: this habit
would always make you infer that a lecture was terse, never that it wasn’t. And
suppose that every lecture has some chance of being terse. Then whenever your
premise (‘this is a lecture’) is true, your conclusion (‘this is terse’) has
some chance of being true. And if this chance is high enough, your prediction
is warranted. [Mellor 1988]
Being warranted depends on what the
laws of nature are. But providing there is a sufficient natural uniformity,
induction is warranted. Now putting it like this (Mellow does not) invites a
comparison with versions of the problem of induction going back to Hume in
which defences of induction that invoke the uniformity of nature face a
problem. Since a claim about uniformity is not a ‘relation of ideas’ it must be
a matter of fact. But it isn’t a directly perceivable matter of fact and thus
must be the result of an inference from what can be observed. What inference?
Well induction. So if the defence of induction requires appeal to the
uniformity of nature, it looks to be circular. Here’s Mellor’s summary of that
worry.
So far so good - provided these warrants needn’t be
self-intimating. I say the law that all tree frogs are green warrants my
inferring that something is green from the fact that it’s a tree frog. But
suppose I must know that I have this warrant. Then I must know this law. So I
must believe it, and this belief must be warranted. But the law entails the
very inference which it’s meant to warrant: tree frogs can’t all be green
unless this one is. So unless my inference is warranted already, my belief in
the law won’t be warranted. Thus to claim that the law is what warrants this
particular application of it simply begs the question of whether it’s warranted
at all. [Mellor 1988]
The solution is to part company with an
assumption built into Hume’s version: that justification is self-intimating or that
to be justified, one must know the justification. Mellor’s solution is an externalist
denial of that. One can be warranted without knowing the warrant.
This is the stock objection to contingent solutions to the
problem of induction: they beg the question. And so they would if
belief-warrants had to be self-intimating. But … they don’t. The law that all
tree frogs are green can warrant the habit of inference which induction will
then give me, just because I needn’t know that it does. I can know by induction
that a frog is green without knowing that law, just as I can know that it’s
green by looking at it without knowing I’m not colour-blind. I may know the
law, just as I may know that I’m not colour-blind; but I needn’t. So my saying
that the law is what warrants this induction doesn’t beg the question. [Mellor 1988]
The lecture conducts some further
business. Because of the nature of the appeal to indeterministic or
probabilistic laws in this epistemological context, Mellor reminds us that
these can be thought of as objective chances with mind-independent causes and
effects. He also explains the advantage of larger sample sizes in the premises
of inductions and why counter-induction is generally a less good strategy than
induction in a lawlike world but that no strategy triumphs in a lawless world. But
the general idea is that a possibly probabilistic but generally lawlike
universe warrants a form of inference which moves between nomologically related
properties.
One question this prompts is the
relation of warrant and truth. In the case of observation, there is a potential
for a gap which isn’t there in a disjunctive account. Since ‘seeing’ a sparrow
does not entail that there is a sparrow, a warranting but merely probabilistic
relation between sparrows and beliefs in sparrows can coincide with the falsity
of a belief. So Mellor accepts the idea that two subjects can be equally warranted
in their beliefs, one can be false and the other true but the latter subject
nevertheless have knowledge. That seems odd as it seems that the fact that
their belief is true is, relative to their counterpart, a matter of some luck
(likely though they are to be right).
A disjunctivist like McDowell can
attempt to account for the fallibility of observation by conceding that whilst
that faculty as a whole is fallible, its exercise on particular occasions falls
into two sub-groups: actually seeing the sparrow or merely thinking one sees
the sparrow. In the good disjunct, no probability is in play: the sparrow is
simply there in view. So the warrant in the good disjunct is of a quite
different kind to that in the bad disjunct. (The worry now is whatever is surprising
about the idea that warrant and truth cannot come apart symmetrically.)
Returning to Mellor, in one kind of
case of failed induction, there seems to be a similar possibility for a false
but warranted induction: the unlucky case in which a probabilistic connection
fails to yield the fact that fits the inductively supported conclusion. But I
wonder about a case in which, for fully deterministic reasons, one causal
regularity is trumped by another. The regular spinning of the Earth may be
interrupted by a supernova, eg. In that case, the sun’s previous behaviour
considered alone might be thought to warrant the inductive belief that it would
rise the next day but the physical system as a whole suggests that such a
belief is not, in fact, warranted. The former approach would require some
principles of individuation of the physical system considered independently of
the subject’s grasp which seems tricky. But the latter approach would undermine
the possibility, in deterministic cases, of warranted but false beliefs. Whilst
it might seem the exercise of epistemic responsibility, the inference isn’t in
fact warranted. This seems odd.
The appeal to me, however,
of Mellor’s approach is that it sidesteps the ‘internalist’ version of the problem
of induction. Not requiring that one knows the principle of uniformity of nature
more generally, or the local laws more specifically, blocks the circularity which
Hume stresses. So is there a way of embracing that and which maps something like
a disjunctivist ‘correction’ of the warrant of observation onto induction? Not quite,
I think.
Note that there are opposing
tensions in calling McDowell’s disjunctivist picture of seeing ‘internalist’ and
‘externalist’. It is externalist, or perhaps more precisely not internalist, insofar
as the fact that one occupies the good or the bad disjunct depends on a worldly
favour which is beyond what the subject can control (hence the rejection of the
interiorization of the space of reasons). But it is internalist, or rather not externalist,
insofar as, if one is in the good disjunct, the seen sparrow is simply there for the subject, in no sense external to their experience
(contra the highest common factor approach).
At first sight, it doesn’t
seem possible to play quite this game with the inductive base. One cannot simply
see in the observed past behaviour of ‘sunrise’, for
example, the next day’s rise, that very event. Recall that in setting up Hume's
problem, the connection between past and future regularities is a matter of fact
rather than a relation of ideas. But then, within the class of matters of fact,
such a regularity is not directly observable and must be extracted or inferred from
what is observable (past regularities). At that point, we realise that the principle
needed to do this presupposes the very thing that was supposed to be the conclusion
of the inference.
With Mellor in mind, we
might suggest that the observed past sunrises physically necessitate the next day’s
rise. But if so, it isn’t so clear what the difference is in what is available to
the subject between observing past sunrises which necessitate a future sunrise and
sunrises which do not. The subsequent necessitation seems to be something external
to what is observed and thus external to the subject’s grasp. So the feature of
the disjunctivist account of observation which merits the description 'internal
or at least not external' does not apply to Mellor's view of the law that connects
past to future sunrises. Such a law is not part of what the subject can take in.
In McDowell’s discussion
of the testimonial transmission of knowledge, he suggests that we speak of hearing,
in another’s words, that things are thus and so. There is also here a possible line
of analogy in that, for one to hear that things are thus and so, the interlocutor
must be reliable and that is not something one typically ensures oneself. So their
reliability is not in their utterance but is a precondition for hearing
in their utterance the facts.
There is, however, also
a potential disanalogy to induction here. The ‘content’ that the sun will rise tomorrow
– or the sun’s rise, tomorrow – is not there in the induction base to be embraced. It seems
that it must be inferred from that. This might suggest that there isn’t an equivalent
idea to the mix of internal and external that characterises observation in the good
disjunct. The link from past to future seems, as it is with Mellor’s account, an
external addition to is observed. But the problem of making the connection external
is that were it ‘blankly external’, as McDowell sometimes says, then it is hard
to see how it can contribute the subject’s epistemic standing.
To get something akin to
the disjunctivist account of the good disjunct for observation for the case of induction,
I think we need to think along these lines. The subject who bases a prediction for
the future on experience of past events must not merely take the past facts as atomic.To
have a bearing on the future, they see a kind pattern or ‘habit’ in the sun’s behaviour.
They see in the past behaviour of the sun its ongoing, and hence future implicating,
pattern. And if the pattern really is ongoing – by contrast with a kind of bad disjunct
in which the seeming pattern is not really there – then the subject does have a
justification which balances internal and external.
Hume’s problem of induction
is generated not just from the fact that the inference from past to future is not
a ‘relation of ideas’ and hence must be a matter of fact but also because it is
not a matter for direct perception and hence must be an inference. But perhaps the
latter distinction does not neatly divide two aspects of the inductive base: atomic
facts and subsequent inference. One sees in the facts the ongoing pattern.
McDowell’s own comments
on the problem of induction are aimed rather differently. He attempts to deconstruct
the starting assumption which compares induction with observation unfavourably.
But I wonder whether by denying the separation of observation and induction they
also sustain something like a disjunctivist view of seeing the enduring pattern
in the past events:
there cannot be a predicament
in which one is receiving testimony from one’s senses but has not yet taken any
inductive steps. To stay with the experience of colour... colour experience’s being
testimony of the senses depends on the subject’s already knowing a good deal about,
for instance, the effect of different sorts of illumination on colour appearances...
[McDowell 1998: 411]
So the supposed predicament
of the inductive sceptic is a fiction... Hume’s formulation can seem to describe
a predicament only if one does not think through the idea that its subject already
has the testimony of the senses and this means that scepticism about induction can
seem gripping only in combination with a straightforwardly interiorizing epistemology
for perception. [McDowell 1998: 412].

Schizophrenia & the nature of delusions: to believe or not to believe?, Ecole Normale Supérieure de Lyon
After a very thorough taxonomy of possible positions offered by Jean-Michel, Sean Gallagher seemed surprised and faintly disturbed to be classed as occupying a kind of doxastic position. He suggested the analogy of taking a bath: in so doing, beliefs are involved but that isn't what having a bath is mainly about. So whilst his account has implications about beliefs, he wanted to resist the doxastic label.
In his presentation, he recapitulated the account given in his paper in the Broome and Bortolotti 2009 book which criticises both top down and bottom up accounts and sketches a more general idea of delusions as the inhabiting of a different and delusional world. This, he suggested, allowed for the description of all the standard ways in which delusions have surprising properties. But he went on, beyond that paper, to present a kind of two factor biological account, plus cultural factors to shape specific content. (The second factor being a pair of localised brain mechanisms for failing to spot cognitive errors to distinguish between healthy occasional suspension of reality whilst reading novels etc. and a more permanent delusional suspension.)
I was a little unsure about how the two themes fitted together. I guess the former picture is non-doxastic in the sense that Sean's preferred account of access to the real world is not based on intellectual, theory-theory theorised beliefs but on a richer embodied orientation. So, to put it flippantly, he also has a non-doxastic account of beliefs. But I wasn't sure what the idea of different world really added to any agglomeration of piecemeal descriptions of delusions provided by their subjects or by clinicians. And then I wasn't sure how it related to the two (plus one) model of delusions which followed. Perhaps these are simply two independent ventures: an analysis of the nature of delusion and a suggestion for their causal explanation.
Joining us on Skype, Keith Frankish presented a thumbnail sketch of his account of delusions as acceptances. Starting with a distinction between type 1 and the 2 beliefs as:
1: behavioural dispositions which are non-conscious, accessed either by actual behaviour or sometimes by imagining what one would do and strongly subject to rational norms
2: occurrent thought which are conscious, available to verbal report, weakly subject to rational norms (slips of mind etc). (They are also controlled, discrete, binary.)
Compared to these two options, delusions look more like type 2 beliefs. But they, generally, look even more like acceptances, he argued. An acceptance is the strategy (cf of scientists or lawyers) of using propositions as premises of hypotheses but with no need actually to believe them. This picture assumes reasoning is intentional, consciously controlled and binary (like type 2 beliefs). But it can be pragmatically motivated (unlike type 2 beliefs). And it can be context relative (again unlike type 2 beliefs).
On this model, type 2 belief is thus a subset of acceptances: unrestricted, evidence-sensitive acceptance or 'doxastic acceptance'.
So the claim that delusions are acceptances amounts to either:
Option 1 doxastic acceptances.
Option 2 non-doxastic acceptances.
If option 1, then they are improperly executed doxastic acceptances ie. irrational beliefs. If 2, they were never intended to be unrestricted: rational pragmatic acceptances. As indirect evidence for this idea, Keith suggested that this picture coped well with Akrasia.
1: the action dictated by a promising policy is incompatible with some other desirable action and
2: the desire to perform this other action outweighs the desire to carry through one's premising policy.
Similarly for delusions not motivating action. And hence this suggests new questions about, not what causes someone to believe that they are dead, but what purpose does the adoption of such an acceptance for the purposes of argument serve?
I asked whether he worried about whether subjects with delusions conceived of them as acceptances. He replied that the policies which fixed an acceptance were type 1 beliefs and desires and hence non-conscious and hence subjects did not so conceive their delusion. It slowly dawned on me that this seems to suggest something like this picture. Conscious type 2 states are the result of non-conscious type 1 states which - interestingly - are nevertheless second order (not his terminology) in so far as they are about policies for dealing with contents (so beliefs about beliefs etc). So the conscious access to type 2 seems to come out if nowhere. One discovers the nature of one's type 2 state (does this include the difference between beliefs and desires as well as doxastic and non-doxastic acceptances?) by interpreting oneself (as others do). This was a price he was prepared to pay. (Standard hermeneutic worries that I may have got hold of the wrong end of the stick apply more than usually to this account of his views, I should add.)
Just now I am listening to a talk by Patrice Soom offering a formal model based on functionalism of the claim that delusions might impact on other mental properties but not vice versa. One claimed virtue is its immunity to objections to the DSM definition such as a commitment to doxastic statement, the extrinsic characterisation. It fits the Coltheart etc two factor model. It is a brave account that any unrevisable belief is a delusion but Patrice was hip to this and embraced it is an interesting prediction of the model. Still, I can't help thinking that a question has been begged in ascribing contents - eg. that they are dead - and then adding to that the subject does odd things with that content (in this case, regards it as unrevisable). I can't help being suspicious about ever using the sentence: 'Jones thinks that she is dead'.
PS: Keith has now (18/12) sent me a substantial email correcting my understanding of his view. Once I've digested it, I will post a follow-up.

Bootstrapping conceptual normativity?
Abstract
Both anti-reductionist and reductionist accounts of linguistic
meaning and mental content face challenges accounting for learning a first
language. Anti-reductionists cannot account for a transition from the
pre-conceptual to conceptual without threatening to reduce the latter to the
former. Reductionists of a representationalist variety face the challenge of
Fodor’s argument that language learning is impossible.
This paper examines whether Ginsborg’s account of primitive normativity might provide some resources for addressing these issues. Rejecting her ‘no conception’ account of normativity in favour of a demonstrative, local conception provides one response to Fodor’s argument which is available to an anti-reductionist and at least a further hint as to how context-independent linguistic concepts can be developed from context-dependent local conceptions of how to go on.
This paper examines whether Ginsborg’s account of primitive normativity might provide some resources for addressing these issues. Rejecting her ‘no conception’ account of normativity in favour of a demonstrative, local conception provides one response to Fodor’s argument which is available to an anti-reductionist and at least a further hint as to how context-independent linguistic concepts can be developed from context-dependent local conceptions of how to go on.
The problem of concept learning
One of the challenges for an anti-reductionist account of
linguistic meaning and mental content is making space for an account of concept
learning. If, following John McDowell for example, one takes the space of
reasons to answer to a distinct constitutive ideal from that of the realm of
law, it is hard to see how the route from the latter to the former can be articulated.
Any such articulation would threaten to provide – what the anti-reductionist
denies – a reduction of the concepts of the space of reasons to those of the
realm of law.
McDowell himself suggests that Wittgenstein’s phrase ‘light dawns
gradually over the whole’ provides a natural metaphor for learning a first
language ‘for one’s dealings with language to cease to be blind responses to
stimuli: one comes to hear utterances as expressive of thoughts , and to make
one’s own utterances as expressive of thoughts’ [McDowell 1998: 333]. But he
suggests that this process cannot be limited to a few sentences but involves
working one’s way ‘into a conception of the world’. Suggestive though
Wittgenstein’s phrase is, it does little to shed light on how the process of
language learning might come about so much as summarise, albeit neatly, the
fact that some such process does come about.
Whilst anti-reductionists face a principled problem, the most
striking recent philosophical argument about language learning comes from one
of their reductionist opponents. In LOT2: The language of thought revisited,
Jerry Fodor sets out a specific argument for the difficulty of accounting for
concept acquisition [Fodor 2008]. Or rather, he argues that such language
learning must be impossible.
Fodor’s argument has four steps:
1.
Concept learning is a rational process.
2.
The only plausible rational process is
hypothesis formation and testing.
3.
But that requires the conceptual representation
of the hypothesis, which presupposes possession of the concept to be learnt.
4.
So concept learning is impossible.
The first step contrasts learning as a rational process with any
form of non-rational process of concept acquisition such as by surgical
implantation, swallowing a pill or hitting one’s head against a hard surface.
Fodor then argues that the only plausible candidate for such a rational process
is a ‘process of projecting and confirming hypotheses about what the things
that the concept applies to have in common’ [ibid: 132].
The argument for the third step is couched in the terms of
Fodor’s ‘Representational Theory of Mind’ (RTM) and is, initially at least,
restricted to primitive, that is non-definable, concepts.
Consider any concept that you’re prepared to accept as primitive,
the concept GREEN as it might be. Then ask ‘What is the hypothesis the
inductive confirmation of which constitutes the learning of that concept?’
Well, to acquire a concept is at least to know what it’s the concept of ; that
is, what’s required of things that the concept applies to. So, maybe learning
the concept GREEN is coming to believe that GREEN applies to (all and only)
green things; it’s surely plausible that coming to believe that is at least a
necessary condition for acquiring GREEN. Notice, however, that (assuming RTM) a
token of the concept GREEN is a constituent of the belief that the concept
GREEN applies to all and only green things. A fortiori, nobody who lacked the
concept GREEN could believe this; nobody who lacked the concept GREEN could so
much as contemplate believing this. A fortiori, on pain of circularity, coming
to believe this can’t be the process by which GREEN is acquired. [ibid: 137-8]
And hence, he argues, no primitive concepts can be learnt. (He
goes on to lift this restriction but I will ignore that move here.)
Fodor’s RTM is implicit in the way he sets out the third stage:
that a token of the concept is a constituent of the belief about the
extension of the concept. This reflects his idea that concept possession is
explained by inner vehicles of content: mental representations. But even
without RTM, it is plausible to argue that the capacity to have such a belief –
however realised – presupposes possession of the concept, ascribed at the level
of the person, and so the argument floats free of Fodor’s particular views.
The principled problem of describing a process of concept
learning from an anti-reductionist perspective and Fodor’s specific argument
that concept learning is impossible presents a two-fold challenge. Can Fodor’s
argument be blocked and if so can the materials used to do that shed light on
concept learning even from an anti-reductionist perspective?
Ground rules
In what follows, I will make two substantial but related assumptions.
First, that concept learning is normative. Second, that it is, in some sense, a
rational process.
The view that concept learning is normative might follow from the
view that concept use is normative. Such a view has been espoused by Blackburn,
McDowell and others. But it has recently been contested by philosophers also responding
to Kripke’s argument for meaning scepticism which starts – or, at least, seems
to start – by assuming that meaning is normative and then using this to undermine
its factual base. McDowell’s response is to agree that the claim that meaning
is normative is itself philosophically innocuous and thus seek to show how that
escapes Kripke’s argument. Anti-normativists such as Hattiangadi agree that
meaning is connected to a notion of correctness but deny that correctness need
be a normative notion. For example if R states a rule for the correct use of a
term t which applies in virtue of features f
R (x)(t applies correctly to x ↔ x is f)
then Hattiangadi argues that this ‘simply states the correctness conditions of an expression; it
does not tell me what to do’ [Hattiangadi 2007: 223]. A mere descriptive sorting does not appear
to raise the problems for an account for meaning that the claim that it is normative
appears to.
One of
the key arguments deployed by anti-normativists is that meaning yields no clear
prescriptive norm in itself. Correctness conditions, for example, do not
prescribe that a true (or more broadly correct) use should be made unless also
combined with a prescriptive norm that one ought to speak the truth (or more
broadly correctly). And that additional norm seems too strong for specifically
semantic normativity.
Nevertheless, however that debate pans out, a rational process of
concept acquisition or learning does
look to be normative. In this context, correctness conditions are not merely a
neutral way of sorting subsequent utterances but rather constitute the aim or
goal of developing linguistic competence. (This is not to say that learning
must always involve practising with only true utterances, customary though that
may be. Parents may, and in my experience often do, teach correct use
indirectly be deliberately calling out the wrong names of objects as a kind of
game.) If an anti-normativist wishes to argue that the relevant prescriptive
ought applies not directly in virtue of the rules of correctness of words but
an adoption of those rules as the goal of concept learning, so be it.
The second assumption is that concept learning is, in some sense,
a rational process. McDowell calls the acquisition of a first language a matter
of being ‘cajoled’ [ibid: 333]. It is possible that being the recipient of such
cajoling is not so much a rational response as being brutely changed in such a
way that one can become a rational subject and make subsequent rational
responses. But I will assume that it is possible to say something about
rationality of the proto-linguistic responses of a subject in such a position.
My stalking horse will be Hanna Ginsborg’s account of ‘primitive
normativity’.
Ginsborg on primitive
normativity
Ginsborg’s account of primitive normativity is – like many of the
anti-normativists - designed as a response to Kripke’s meaning scepticism
[Kripke 1982]. As Ginsborg interprets the dialectic, Kripke assumes that grasp
of what one meant by a word in the past sets the standard for the correctness
of one’s current use of it. Part of what justifies giving the answer ‘125’ to
the question of what ‘57 plus 68 equals’ is what one has previously meant by ‘plus’. Kripke then mounts a
sceptical attack on how we can now know what we did earlier mean. Perhaps by
‘plus’ we really meant quus which tracks the plus function for past usage but
not the two current numbers.
In response, Ginsborg denies that to claim that one ought to say
‘125’ one needs first to establish that one previously meant addition. That one
ought to say ‘125’ is independent of any assumption about past meanings. She
claims: ‘I maintain that there is a sense in which you ought to say “125,”
given the finite list of your previous uses, independent of what meaning, if
any, those uses expressed’
[Ibid: 232-3]. Given this context, ‘primitive normativity’ is a normativity
independent of, and prior to, grasp of meaning. It is located below the level
of facts about meaning though still irreducibly normative. She sets out an
example of a child who is able to recite numerals and has learnt to count up in twos conuting from
‘40’ with ‘42’. Ginsborg characterises a conceptual-normativist account
of the child’s saying ‘42’ as follows:
[T]he child says “42” after “40” because she recognizes,
although without being able to put that recognition into words, that she has
been adding two and that 40 plus two is 42. Her sense of the appropriateness of
what she is saying thus derives from her recognition that it fits the rule she
was following: a rule which she grasps, even though she is unable to articulate
it. [ibid: 238]
On this higher level view, the correctness of the move – saying
‘42’ – depends on gasping a rule governing it. Primitive normativity involves
less than that. But, at the same time, it involves more than the merely
reliable dispositional reactions of a suitable trained parrot. By contrast with
such a parrot, that the child does not respond ‘blindly’ to her circumstances.
Even though she does not say “42” as a result of having
grasped the add-two rule, nor a fortiori of having “seen” that 40 plus two is
42, she nonetheless “sees” her utterance of “42” as appropriate to, or fitting,
her circumstances. [ibid: 237]
So even though the child lacks full blown conceptual mastery, she
has a sense of appropriateness, fitting or belonging which merits the label ‘normativity’. The parrot lacks
any such sense and hence is merely governed by dispositions not norms.
Ginsborg gives a second example of the kind of middle level
behaviour. She describes a child sorting coloured objects before she has
acquired determinate colour concepts.
As she puts each green object in the designated box, it is
plausible that she does so with a sense that this is the appropriate thing to
do. She takes it that the green spoon “belongs” in the box containing the
previously sorted green things and that the blue spoon does not, just as the
child in the previous example takes 42 and not 43 to “belong” after 40 in the
series of numerals. But her sense of the appropriateness of what she is doing
does not, at least on the face of it, depend on her taking what she is doing to
accord with a rule which she was following, for example, the rule that she is
to put all the green things in the same box. For her grasp of such a rule would
presuppose that she already possesses the concept green. [ibid: 235]
There are two sorts of general consideration to support the idea
of some sort of primitive normativity. One relates to Ginsborg’s specific
dialectical context. Mere dispositions will not provide a satisfactory response
to Kripke’s sceptical argument whilst full blown conceptual normativity will be
vulnerable to his original argument. (This is not to say that these are clear
cut but they provide a rationale for attempting to articulate a middle ground.)
The other relates back to Fodor’s argument. Mere dispositions
seem to leave too much of a gap still to cross to explain how a dispositional
stage might be an intermediary en route to conceptual mastery. By contrast,
invoking full blown conceptual mastery to characterise the counting child is to
provide no answer to the question how basic concepts can be learnt.
Nevertheless, there are two options for characterising primitive
normativity based on two distinct things Ginsborg says. She says of the
counting child both that:
1: ‘she lacked any conception of what her saying “42”
after “40” had in common with her having said “40” after “38”’ [ibid: 234
italics added]
but also:
2: ‘it seems plausible to imagine her insisting, with no less
conviction than a child who was able to cite the add-two rule, that “42” was
the right thing to say after “40”: that it “came next” in the series, or
“belonged” after 40, or “fit” what she had been doing previously’ [ibid:
234 italics added]
The former states that the counting child has no conception of what one move has in
common with a previous move. The second allows for the possibility of some conception that the next move fits or belongs (ie does have something in common) with the previous one in
context. The latter allows for a conception albeit a local one. Which does
Ginsborg hold?
‘No conception’ primitive
normativity
There is reason to think Ginsborg believes in the more radical,
minimal version. One suggestive passage runs:
The utterance, from [the counting child’s] point of view, is
not appropriate to the context in virtue of its conforming to a general rule
which the context imposed on her, for example, the add-two rule. Rather, she
takes it to be appropriate to the context simpliciter, in a way which
does not depend for its coherence on the idea of an antecedently applicable
rule to which it conforms. [ibid: 234-5]
Now one way to interpret the phrase ‘antecedently applicable
rule’ is a context-independent general specification of a rule. In the context
of a mathematical series, that is a plausible way of cashing out full blown
conceptual normativity. And hence its rejection might allow for a merely
demonstratively specified local
conception of the demands of a rule. On this alternative view, whilst the child
does not have a general conception of what it is to add two, cannot grasp its
relation to other aspects of arithmetic for example, she can, nevertheless,
recognise in some particular context that saying ‘42’ is the right move.
But the phrase ‘antecedently applicable rule’ might equally be
taken to mean, and hence to rule out, any
conception of a rule. If so, the context imposes a sense of what move belongs with previous moves, of what
next move is right, independently of any conception the child has of what she
is doing. The way the quotation continues adds to this latter impression:
This is not to deny that the normativity depends on any facts
about the context, since the appropriateness of “42” depends on her having
recited that particular sequence of number words. But it is to deny that her
claim to the appropriateness of “42” depends on her recognition of a rule
imposed by the context in virtue of the relevant facts, or a fortiori on her
recognition of “42” as a correct application of the rule. [ibid: 235]
This suggests a picture according to which facts about the
context external to the child’s conception of the demands of the rule nevertheless
make normative demands on her. The context of having counted up to 40 makes
saying ‘42’ appropriate independently of her conception of what she is doing.
‘42’ belongs to what has gone before,
is thus normatively connected to it, but she does not recognise that this is
the demand that the rule makes in the context.
A second passage provides a distinct argument for the ‘no
conception’ view of primitive normativity on the assumption that even a local
conception of what the next move is requires some grasp that this is relevantly
the same as previous moves.
[T]he child’s recognition of similarity is not sufficient to
account for her taking herself to be going on appropriately. She must not
merely take herself to be going on the same way; she must also take it that
going on the same way is the appropriate thing to do in the context, which is
to say that she must grasp a rule with a content like go on the same way
or do the same thing you were doing before. We are thus left with the
problem of how to account for her grasp of this rule... [ibid: 240]
The argument is that grasp of sameness is insufficient for
knowing how to continue. One would need to grasp the further rule that one should go on in the same way, that this is what the relevant normative demand is.
There is something to this worry. There seems little prospect of
factoring grasp of a rule into grasp of sameness plus grasp that sameness is
what one ought to aim at. Wittgenstein stresses that agreement is internal and
relative to the particular rule [cf Wittgenstein 1953 §224]. Thus grasp of the
rule and grasp of what agrees with it and hence what is relevantly the same in
virtue of according with the rule goes hand in hand.
But this point applies equally to what Ginsborg does make
explicit: that the child grasps that the next move fits, belongs or is appropriate to the context. Those
notions are equally insufficient for going on correctly. (A rule could dictate
that the next move should stand out from, rather than fitting, what has gone
before.)
It seems on balance, however, that Ginsborg does subscribe to a
minimal ‘no conception’ version of primitive normativity (I will return to a
further strategic reason why this is so shortly). Further, she seems not to be
alone. In a passage in which she discusses how little may be necessary for rule
following, Julia Tanney considers the conceptual possibility of rule following
without the ability to cite higher level rules, or to repeat the performance or
without training. She comments:
[I]f we agree with the thought that someone might be able to
solve Rubik’s Cube even if she had never been trained by anyone, then this
gives us a reason to reject the idea that there must be an internal connection
between the rules that govern an activity and the individual who makes the
moves. We can say that it is sometimes enough to credit someone with playing
the game if she acts in accordance with the rules. Knowledge (implicit or
otherwise) has dropped out of the picture. To insist that someone cannot solve
the puzzle unless she somehow conceives the rules (even if she cannot
articulate them, even to herself) and acts in the light of her conception of
the rules is simply dogmatic. What would justify such insistence? If this
person were suddenly entered in a contest and produced the cube with the
colours in the right places, we would not withhold the prize because she merely
acted in accordance with, but did not follow, the rules. Acting in accordance
with the rules is solving the puzzle in certain cases. [Tanney 2013: 85-6]
On this account, having rejected a number of potentially
necessary substantial claims as in fact unnecessary for rule following, Tanney
concludes that, in the right context, mere accord
with a rule constitutes rule following.
Further, this does not seem to be merely a claim about the epistemology of the
ascription of rule following – which, indeed, in the right context, apparent
accord warrants the further ascription of intentional rule following – since
Tanney connects it to the rejection of an internal connection between rules and
agent. An epistemological interpretation, by contrast, is consistent with
maintaining that accord in performance is evidence
for such a connection, amounting to the grasp of the rule by the agent.
Instead, and in response to a number of bogus explanations of rule following
which fail because they presuppose precisely the abilities they purport to
explain, Tanney offers a kind of deflationary approach. The failure of
cognitivist explanations of rule following leads to a rejection of cognition.
‘To insist that someone must conceive the rules somehow – even if what it would be for her to conceive these rules
is inaccessible to us – is misguided; it fails to explain anything’ [ibid: 86].
Despite this support, the ‘no conception’ version of primitive
normativity faces a key objection. It severs the connection between primitively
rule-governed behaviour and intentional action and the blurs the distinction
between mere accord with a rule and intentionally following it. It is this
distinction which marks the difference between a merely dispositional parrot,
whose behaviour may accord with a rule available to a third person description,
and a human subject with some sense of her new moves fitting or belonging with
what went before, some sense of normative correctness.
But there is no need to get into such difficulty if the aim is
merely to fit an intuitive description of the phenomenology of the child’s
early performance in, as we might say, counting in twos or grouping by colour. The
middle ground between dispositional accord with a rule and full-blown
conceptual normativity is not the primitive normativity of someone with no conception of what she is doing but
with a merely local conception. Such
a conception is not tied to the local context of counting or sorting objects
brutely or merely externally in virtue of an ascription of rule-accord by an
observer. Rather, it is expressed by the demonstrative judgements of the child
and her capacity to demonstrate and explain by example what fits with what she
has been doing.
This idea runs counter to one of Ginsborg’s explicit claims: ‘I
maintain that there is a sense in which you ought to say “125,” given the
finite list of your previous uses, independent of what meaning, if any, those
uses expressed’ [Ibid:
232-3 italics added]. On the local conception this is wrong. Correctness is
tied via a local conception to what a speaker’s past utterances expressed even if the speaker is unable
to offer a context-independent linguistic codification of her actions as
instances of following the plus-two rule or the sorting of green objects. Her
conceiving of her actions might not extend very far up the natural numbers (eg
beyond 100) or to cover darker or lighter shades of green (by contrast with the
vivid colours of children’s toys). So it is potentially doubly local:
expressible only in some particular context of practical demonstration (by
contrast with context-free linguistic codification) and covering only some
particular instances and thus not actually extensionally equivalent to our concepts of plus two, or green but
rather a primitive version of them.
I suggested that there is a further strategic reason why this
view is unavailable to Ginsborg. She deploys the idea of primitive normativity
as a novel response to Kripke’s sceptical argument. Her aim is to sidestep the
arguments Kripke deploys against any justification one can currently offer for
knowing what one meant in the past by one’s words, thus to undermine a standard
of correctness for current use. Primitive normativity has, for those strategic
purposes, thus to be independent of any conceptual conception. A local
conception is, however, a form of conceptual conception and its expression in a
pattern past, finite examples is just as much subject to Kripke’s argument as a
full blown linguistic concept. That is to say, that is not part of a new defence of meaning against Kripke’s
argument.
‘Local conception’
primitive normativity and language learning
Primitive normativity guided by a local conception of what a
speaker is doing promises a partial answer to the initial two-fold challenge of
describing language learning. One aspect of Fodor’s challenge was to sketch a
rational mechanism for concept acquisition (hence learning). On the assumptions that a) the only plausible option is hypothesis
formation and testing and b) hypothesis formation presupposes the very
conceptual mastery in question, no rational mechanism seems possible.
Primitive normativity guided by and expressive of a local
conception is a plausible intermediary between mere dispositional accord with
rules and full blown linguistic mastery. The intermediate stage involves
testing the hypothesis that a new linguistic concept expresses a content
previously grasped in some local demonstrative manner. As suggested above, the
grasp of a full blown linguistic concept may requires the piecemeal extension
of a more primitive, merely local conception of a rule. But there may be some
gradations of understanding between having no and a first language.
Of course, the very idea of an essentially situation-dependent
conceptual understanding does not fit within the basic idea of Fodor’s
representational theory of mind according to which content always has an inner
vehicle. So no such middle ground is available to Fodor himself. Thus for
anyone uneasy with Fodor’s innativism, his argument against language learning
remains a powerful reductio of his representationalism. But the idea does
provide a way to address the version of his argument mentioned at the start
framed in terms of prior concept possession but agnostic about Fodor’s account
of inner vehicles.
What of anti-reductionism? A local conception offers only partial
progress here. By contrast with Ginsborg’s own account of primitive
normativity, the idea that normativity always presupposes that the subject has
some albeit local conception according to which she acts provides no middle
ground between the ‘space of reasons’ and the ‘realm of law’ or the ‘manifest
image of man in the world’ and the ‘scientific image’. Even a local conception
belongs in the space of reasons or the manifest image. So it cannot be part of
a route into those spaces from without. But it does help put a little flesh on
the bones of the idea that ‘light dawns gradually over the whole’.
‘The whole’ need not merely be understood to be the gradual
acquiring of a world view, as Wittgenstein describes in On Certainty (from where the phrase comes) [Wittgenstein 1969
§141]. It can also include mastery of primitive albeit still conceptually
structured rules. This is no account of how conceptual normativity can be
bootstrapped from non-conceptual dispositions but does suggest how more complex
and abstract concepts cane be developed from more primitive local forms.
