Kant’s Best Ideas -- and Worst

Abstract Kant’s argument that space, time, and the categories are the necessary forms of human experience are powerful; his transcendental idealism, that is, his arguments that spatiality and temporality in particular are only forms of human representation are not. His foundation of morality on the idea of preserving and promoting the maximal but equal freedom of all is profound; his conviction that human beings are always free to do what morality requires, based as it is on his transcendental idealism; is not. But his arguments that completeness in both scientific and moral knowledge are always only regulative ideals are compelling, with no corresponding downside.
