Kant's postscript to this added that the mind is not a blank slate, tabula rasa, (contra [[John Locke]]), but rather comes equipped with categories for organising our sense impressions. This Kantian sort of idealism opens up a world of abstractions (i.e., the universal categories minds use to understand phenomena) to be explored by reason, but in sharp contrast to Plato's, confirms uncertainties about a (un)knowable world outside our own minds. We cannot approach the ''[[noumenon]]'', the "Thing in Itself" (German: ''Ding an Sich'') outside our own mental world.  (Kant's idealism goes by the counterintuitive name of ''[[transcendental idealism]]''.)

Kant distinguished his transcendental or critical idealism from previous varieties:{{Quotation|The dictum of all genuine idealists, from the [[Eleatic]] school to Bishop [[George Berkeley|Berkeley]], is contained in this formula: “All knowledge through the [[senses]] and [[experience]] is nothing but sheer [[illusion]], and only in the ideas of the pure [[understanding]] and [[reason]] is there [[truth]].”  The principle that throughout dominates and determines my idealism is, on the contrary: “All knowledge of things merely from pure understanding or pure reason is nothing but sheer illusion, and only in experience is there truth.”|''[[Prolegomena]]'', 374}}
