Who developed Kantian philosophy?
Immanuel Kant
Kant calls practical "everything that is possible through freedom", and the pure practical laws that are never given through sensuous conditions but are held analogously with the universal law of causality are moral laws. Reason can give us only the "pragmatic laws of free action through the senses", but pure practical laws given by reason a priori[110] dictate "what ought to be done".[111][112]
