A priori knowledge is knowledge that is acquired independently of experience. It is based on reason, logic, or rational thinking rather than observation or sensory experience. Philosophers describe a priori knowledge as universal and necessary because it can be known through intellectual reasoning alone. Examples include mathematical truths such as 2 + 2 = 4 and logical statements that do not require experimentation or observation to be verified.
In contrast, a posteriori knowledge depends on experience, observation, or empirical evidence. Scientific discoveries and facts learned through experiments are examples of a posteriori knowledge. The distinction between a priori and a posteriori knowledge is a fundamental concept in epistemology, the branch of philosophy that studies the nature and sources of knowledge.
- A Priori Knowledge: Based on reason and logic.
- Independent of: Experience.
- A Posteriori Knowledge: Based on observation and experience.
Therefore, the correct answer is: Experience.
