Stephen L. Talbott tackles the tautology question over at The New Atlantis: Along with his anecdote about the wolf, Bethell argued that evolutionary theory based on natural selection (survival of the fittest) is vacuous: it states that, first, evolution can be explained by the fact that, on the whole, only the fitter organisms survive and achieve reproductive success; and second, what makes an organism fit is the fact that it survives and successfully reproduces. This is the long-running and much-debated claim that natural selection, as an explanation of the evolutionary origin of species, is tautological — it cannot be falsified because it attempts no real explanation. It tells us: the kinds of organisms that survive and reproduce are the kinds Read More ›

In a comment to a prior post material.infantacy writes [remaining post is all his]: If one believes A = A only some of the time, and that A = !A is true for some circumstances, whether they’re referring to logical propositions or a construct of physical reality, then that person is either deluded or devious.  I recently wasted an entire evening trying to reason with someone that (analogously) two flips of a coin could yield a heads and a tails in two distinct ways (HT or TH) giving the combination a 50% chance of success over either HH or TT. This person had already decided that the two combinations were identical, and no amount of demonstration would convince her otherwise. Read More ›

The law of non-contradiction (“LNC”) states that for any proposition “A,” A cannot be both true and false at the same time and in the same formal relation. The existence of the LNC is the very basis of all argumentation, and anyone who denies it also denies meaning, order, truth and logic. For obvious reasons, therefore, it is not only useless but also affirmatively harmful to the search for truth to argue with someone who refuses to admit unambiguously the LNC. Arguing with a person who denies the basis for argument is self-defeating and can lead only to confusion. Only a fool or a charlatan denies the LNC, and this site will not be a platform from which fools and Read More ›
