“A judgment is conscious of its own validity. This shows that the measure of validity to which it refers itself in this consciousness is inherent in the nature of judgment: a judgment is subject to this measure not in virtue of any circumstance in which it may find itself, but simply as judgment. Now when we think of an act simply as a judgment, we refer it to the power as an act of which it is a judgment: the power of judgment. Hence, the measure of validity of judgment is nothing other than the power of judgment. A judgment, being conscious of its validity, refers itself to the power from which it springs (as, e.g., St. Thomas Aquinas observes).” JudgementKantThomasPractical KnowledgeAquinasRödlAnscombe Author:Sebastian Rödl
