A Priori and A Posteriori
In the context of knowledge, "a priori" refers to knowledge gained through reason and logic, independent of experience. For example, knowing that "all bachelors are unmarried" relies on understanding definitions. In contrast, "a posteriori" knowledge comes from experience and observation; for instance, knowing that it is raining relies on seeing or experiencing rain. Thus, a priori is about what we can know without needing to see or test, while a posteriori is about knowledge obtained through sensory experience. Both types contribute to our understanding of the world in different ways.

A priori and a posteriori are terms used to describe how we gain knowledge. A priori knowledge is independent of experience; it is something we can know through reasoning or intuition alone, like mathematical truths (e.g., 2 + 2 = 4). A posteriori knowledge, on the other hand, comes from experience or observation; it requires evidence from the world, such as learning that it rains based on seeing rain firsthand. In essence, a priori is about what we can know without direct experience, while a posteriori involves knowledge gained through our experiences.
