Depravity
I have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinions of himself than on the opinions of others.

- Marcus Aurelius

Excellent question; man loves himself most of all, but is more concerned with what others think of him. Thus his pride does not merely contaminate his heart with self-adoration, but taints all of his inter-personal relationships by seeking validation, approval, and praise from those around him.
