“When, therefore, a man is told, “You (your inner being) are so and so, because your skull-bone is so constituted,” this means nothing else than that we regard a bone as the man's reality. To retort upon such a statement with a box on the ear — in the way mentioned above when dealing with psysiognomy — removes primarily the “soft” parts of his head from their apparent dignity and position, and proves merely that these are no true inherent nature, are not the reality of mind; the retort here would, properly speaking, have to go the length of breaking the skull of the person who makes a statement like that, in order to demonstrate to him in a manner as palpable as his own wisdom that a bone is nothing of an inherent nature at all for a man, still less his true reality.”
― Georg Wilhelm Friedrich Hegel, The Phenomenology of Mind, Vol 1
