What the Tortoise Said to Achilles
Book • 1895
In this 1895 paper, Lewis Carroll presents a thought-provoking dialogue between Achilles and the Tortoise, exploring the concept of infinite regress in logical arguments.
The Tortoise challenges Achilles to use logic to force him to accept the conclusion of a simple deductive argument.
However, the Tortoise leads Achilles into an infinite sequence of hypotheticals, demonstrating that even if one accepts all the premises, there is no logical necessity to accept the conclusion.
This paradox highlights the difficulties in the foundations of logic and the nature of deductive reasoning.

Mentioned by Jim O’Shaughnessy , making a compelling argument for the idea that as you go down the logic tree and you get to the bottom of it, what you find is a human being asserting without proof that something was true.
