Abstract
Immediate (non-Reflective) experience must be distinguished from mediate experience (empirical knowledge). Kant's epistemology is based on the "a priori"--"a posteriori" and analytic-Synthetic distinctions. Four classes of knowledge arise out of combining these two distinctions; each corresponds to a 'reflective perspective'--A way of reflecting upon immediate experience. Reflection based on transcendental, Logical, Empirical or practical perspectives gives rise, Respectively, To knowledge which is synthetic "a priori", Analytic "a priori", Synthetic "a posteriori", Or analytic "a posteriori"
