Hard Problem of Rationality

The paradox that the tool we use to evaluate truth—rationality—cannot be justified using purely rational means without circular reasoning. Why should we be rational? Because it's effective? That's a pragmatic, not rational, argument. Rationality rests on axioms (like "the world is consistent") that must be assumed, not proven. The hard problem is that rationality is the judge, jury, and executioner of thought, but it can't put itself on trial without presupposing its own validity.

Example: "He tried to use pure rationality to convince his friend to be rational. 'You should value logic because... it's logical?' He hit the hard problem of rationality: the foundation of reason isn't a brick; it's a turtle floating in mid-air, and asking 'why?' just makes it fall."
