Can you provide examples of a priori and a posteriori knowledge and explain the differences between them?

A priori knowledge is knowledge that is independent of experience, such as mathematical truths or logical reasoning. An example would be knowing that all bachelors are unmarried without needing to observe every bachelor in the world.

A posteriori knowledge, on the other hand, is knowledge that is based on experience or empirical evidence. An example would be knowing that it is raining outside because you can see and feel the rain.

The main difference between a priori and a posteriori knowledge is the source of the knowledge: a priori knowledge is derived from reason and logic, while a posteriori knowledge is derived from sensory experience.
