What is the difference in Kantian philosophy between the highest truths of reason and of experience?   I came across these ideas in relation to analytic truth and synthetic truth.   What is the difference between HIGHEST TRUTH OF REASON and HIGHEST TRUTH OF EXPERIENCE? Please help me with any examples and explanations. Thanks.

There are two binary opposition underlying these concepts, the synthetic – analytic and the a priori – a posteriori.

Analytic truths, like those of mathematics, are tautological, containing nothing outside themselves, but having the predicate logically inhere in the subject.

Synthetics truths involve a predicate not contained in the subject.

A priori knowledge is that gained prior to experience.

A posteriori knowledge is gained through experience.

A special class of knowledge is the synthetic a priori, that is the precondition of our understanding.

The ideal of pure reason is God.

The highest law of practical reason is the categorical imperative.
