Analytic and Synthetic:
Analytic and synthetic are two key distinctions in epistemology and philosophy of language, often associated with the work of Immanuel Kant.
Analytic: Analytic statements are those in which the predicate concept is contained within the subject concept. In other words, the truth of an analytic statement can be determined solely through analysis of the meanings of the terms involved. Analytic statements are considered true by definition and are tautological. For example, "All bachelors are unmarried men" is an analytic statement because the concept of "unmarried men" is already contained within the concept of "bachelors."
Synthetic: Synthetic statements, on the other hand, are those in which the predicate concept is not contained within the subject concept. The truth of synthetic statements cannot be determined by mere analysis of the meanings of the terms involved but requires empirical evidence or experience. Synthetic statements add new information beyond what is already known in the subject concept. For example, "The cat is on the mat" is a synthetic statement because it adds information about the spatial relationship between the cat and the mat.
A priori and A posteriori:
A priori and a posteriori are distinctions related to the source of knowledge or justification.
A priori: A priori knowledge is knowledge that is independent of experience or empirical evidence. It is based on reasoning alone, often involving necessary truths or analytic statements. A priori knowledge is derived from principles that are known to be true prior to or independently of experience. For example, mathematical truths like "2 + 2 = 4" are considered a priori because they can be known through pure reason without reference to empirical observation.
A posteriori: A posteriori knowledge, on the other hand, is knowledge that is derived from experience or empirical evidence. It is based on observations of the world and requires sensory perception or empirical investigation. A posteriori knowledge is contingent and dependent on the facts of the world. For example, knowledge about the color of the sky or the taste of an orange is a posteriori because it is gained through sensory experience.
Examples:
Analytic statement: "All triangles have three sides." This statement is analytic because the concept of "triangles" inherently includes the property of having three sides. It is true by definition and can be known without reference to empirical observation.
Synthetic statement: "The car is red." This statement is synthetic because it adds new information (the color of the car) beyond what is already contained within the concept of "car." The truth of this statement can only be verified through empirical observation.
A priori knowledge: "All squares have four equal sides." This statement is a priori because it is based on reasoning alone and can be known to be true independently of empirical observation.
A posteriori knowledge: "The grass is wet." This statement is a posteriori because it is based on sensory perception or empirical evidence. One can only know that the grass is wet through direct observation or experience.
