Chaïm Perelman resuscitated the rhetorical tradition by developing an elegant and detailed theory of argumentation. Rejecting the single-minded Cartesian focus on rational truth, Perelman recovered the ancient wisdom that we can argue reasonably about matters that admit only of probability. From this one would conclude that Perelman's argumentation theory is inalterably opposed to natural law, and therefore that I would have done better to have written an article titled "Perelman's Theory of Argumentation as a Rejection of Natural Law."However, my thesis (...) is precisely that Perelman's theory of argumentation connects to the natural law tradition in interesting and productive ways. Perelman referred to natural law in. (shrink)
