Philosophy makes man human

"A man is a 'philosopher' by virtue of being more THOROUGHLY human: he is a 'philosopher' precisely because he possesses and cherishes above the rest of mankind that 'love of wisdom' which is a part of all human nature and because he more reflectively and critically brings to the light and examines the largest and widest implications of the life of all men." - Martin, Clark, Clarke, and Ruddick, A History of Philosophy, pg. 5
