“When mystical elements are introduced into morality, the whole system ends up being corrupted.”

“Having, then, once introduced an element of inconsistency into his system, he was far too consistent not to be inconsistent consistently, and he lapsed ere long into an amiable indifferentism which to outward appearance differed but little from the indifferentism …”

“Love corrupts and absolute love corrupts absolutely. The unreasonable systems of men, that is.”

“To say that corrupt means corrupt the ends is to believe in the immaculate conception of ends and principles. The real arena is corrupt and bloody. Life is a corrupting process from the time a child learns to play his mother off against his father in the politics of when to go to bed; he who fears corruption fears life.”

“If a policy is wrongheaded feckless and corrupt I take it personally and consider it a moral obligation to sound off and not shut up until it's fixed.”

“Do not be deceived: bad company corrupts good morals.”
