Transcendentalism, name now principally employed to denote the great doctrine of Kant and his school, that there are principles of a priori derivation, that is, antecedent to experience, that are regulative and constitutive of not only our thoughts but our very perceptions, and the operation of which is antecedent to and sovereign over all our mental processes; which principles are denominated the categories of thought; the name is also employed to characterise every system which grounds itself on a belief in a supernatural of which the natural is but the embodiment and manifestation. See Natural Supernaturalism.
