text: what is the difference between thoughts & ideas ?   thought or thinking is a mental process which allows beings to model the world, and so to deal with it effectively according to their goals, plans, ends and desires. concepts akin to thought are sentience, consciousness, idea, and imagination.   idea: the content of cognition; the main thing you are thinking about; "it was not a good idea"; "the thought never entered my mind"   thinking: the process of using your mind to consider something carefully; "thinking always made him frown"; "she paused for thought"    kant speaks of the understanding both as a faculty of judgment and a faculty of thought. here he defines thought as "knowledge by means of concepts", where concept is taken in an undetermined sense as "predicates of possible judgments". [a55/b79] kant distinguishes pure and empirical thought about an object and first introduces transcendental logic as that logic "which should contain solely the rules of the pure thought of an object".
