To love is to value. Only a rationally selfish man, a man of self-esteem, is capable of love — because he is the only man capable of holding firm, consistent, uncompromising, unbetrayed values. The man who does not value himself, cannot value anything or anyone. ("The Objectivist Ethics," The Virtue of Selfishness, Ayn Rand)
"In a ham and eggs breakfast, the hen is involved, but the pig is committed".
