" the intellectual “grasp” of a psychological fact produces no more than a concept of it, and that a concept is no more than a name, a flatus vocis. These intellectual counters can be bandied about easily enough. They pass lightly from hand to hand, for they have no weight or substance. They sound full but are hollow; and though purporting to designate a heavy task and obligation, they commit us to nothing. The intellect is undeniably useful in its own field, but is a great cheat and illusionist outside of it whenever it tries to manipulate values. "

― C.G. Jung , Aion (Collected Works 9ii)
