Априори is a term derived from Latin, meaning "from the earlier." It refers to knowledge or reasoning that is independent of experience. In philosophy, it describes concepts that are understood through intuition or deduction rather than empirical evidence. For example, mathematical truths are often considered априори because they can be known without needing to observe physical instances. In contrast, апостериори knowledge is based on experience and observation. This distinction is important in various fields, including epistemology, logic, and science. Understanding the difference helps clarify how we acquire knowledge and the foundations of our beliefs about the world.
