Skeptics are fond of pointing out that no non-circular argument can be given to support inductive reasoning. That is true, but a century ago, Lewis Carroll showed through his modern parable of Achilles and the Tortoise that the same holds as well for deductive reasoning.
Is that really true? What do you think of Bertrand Russell's answer to Carroll?
Russell argued that Carroll failed to distinguish between asserted and unasserted propositions. The statement "if p then q" is not at all the same as "p, therefore q". The Tortoise in Carroll's story failed to make this important distinction, confounding poor Achilles.
