[filed under theme 12. Knowledge Sources / A. A Priori Knowledge / 5. A Priori Synthetic ]

Full Idea

Whatever we can describe at all could be other than it is. There is no a priori order of things.

Gist of Idea

There is no a priori order of things

Source

A Reaction

This is his rejection of Kant's dream, of inferring truths about the world by self-examination. However, compare Idea 23495. He clings to the faith that logic reveals 'something' about reality.
