“No man can ever see his own height. Let me explain what I mean. You cannot see in another man, any more than you have in yourself. Your own level strictly determines the extent to which he comes within your understanding. If your intelligence is awakened, mental qualities in another, even though they may be of the highest kind, will have no affect on you at all……..his higher mental qualities will no more exist for you than colours exist for those who cannot see.”

-Schopenhauer
