A man hasn't got a corner on virtue just because his shoes are shined.

What's virtue in man can't be virtue in a cat.

A tragic situation exists precisely when virtue does not triumph but when it is still felt that man is nobler than the forces which destroy him

Absolute virtue is as sure to kill a man as absolute vice is, let alone the dullness of it and the pomposities of it

A man's virtue is not measured by who he is, but rather by what he does

If the highest things are unknowable, then the highest capacity or virtue of man cannot be theoretical wisdom.
