Final answer:
Aposteriori knowledge refers to information that one can only gain through experience and sensory perception, distinguished from a priori knowledge which is obtained through reason without the need for empirical evidence.
Step-by-step explanation:
Aposteriori knowledge is a type of knowledge generated through experience and sensory perception. In contrast to a priori knowledge which is obtainable through reason alone, aposteriori knowledge is empirical, meaning it is acquired through the senses and can be verified through observation. As an example, the belief that there is a bird on a branch outside of one's window is considered aposteriori because it is a conclusion reached through the direct experience of seeing the bird.
Furthermore, aposteriori knowledge is often termed empirical knowledge and is foundationally propositional. Propositional knowledge refers to the understanding of facts and statements – declarative sentences that hold a truth value. This includes knowledge that can only be gained experientially, such as one's own height, or experiential understanding of learned concepts like multiplication. Philosophers categorize knowledge as either a priori (independent of experience) or a posteriori (dependent on experience), providing a clear distinction between knowledge derived from innate reasoning and that which stems from empirical observation.
