The lady who said that she envied me for not having a conscience, didn’t altogether misread me. Like my mother I have firmness of character; and I don’t understand how a rational creature can be wrong in being or doing what he fundamentally wishes to be or do. He may make a mistake about it, or about the circumstances; or he may be imperfectly integrated, and tossed between contrary desires, not knowing his own nature or what he really wants. Experience and philosophy have taught me that perfect integrity is an ideal never fully realized, that nature is fluid and inwardly chaotic in the last resort, even in the most heroic soul….
- George Santayana, The Background of My Life (1944)
