Metaphysicians, in lieu of the word conscience, which seems appropriated to theo- logical or moral matters, ordinarily ufe that of con- sciousness; whereby they mean an inner sentiment of a thing, whereof one may have a clear and distinct no- tion. In this fenfe they lay that we do not know our own foul, nor are affured of the exiftence of our own thoughts, otherwise than by self-confciousnefs. See Metaphysics.
