Philosophers have put forward the idea that rationality can free itself from reality and create a rational world separated from reality. The problem with this idea is that rationality is fundamentally paradoxically contradictory. If rationality had been consistent, then it could have created such a world, but since it isn’t, it can’t. Instead, rationality can only create consistent models of how reality works, not of what reality is. Rationality will thus always be second to reality.
This fact is why rationality can’t compete with belief. Both of them are fundamentally paradoxically contradictory.
