link to Zeno's Coffeehouse. The site says:
Zeno of Elea, a pre-Socratic philosopher, was born about 490 B.C. His style of argument was to assume, provisionally, the position of the opponent, and then to derive impossible conclusions from it, thus establishing the absurdity of the assumption. In the spirit of this Reductio Ad Absurdum dialectical approach to critical thinking, our Coffeehouse activities will tackle from time to time so-called 'common sense views,' analyzed critically.
