At present, man applies to nature but half his force. He works on the world with his understanding alone. He lives in it, and masters it by a penny-wisdom; and he that works most in it, is but a half-man, and whilst his arms are strong and his digestion good, his mind is imbruted, and he is a selfish savage.
The simple recognition that everyone else wants to be happy and not to suffer, just as I do, serves as a constant reminder against selfishness and partiality. It reminds us there is little to be gained from being kind and generous while hoping to win something in return. Actions motivated by a desire to earn a good name for ourselves are still selfish, even if they appear to be acts of kindness.
If you will think about what you ought to do for other people, your character will take care of itself. Character is a by-product, and any man who devotes himself to its cultivation in his own case will become a selfish prig.
I find that the moment I let a woman make friends with me, she becomes jealous, exacting, suspicious, and a damned nuisance. I find that the moment I let myself make friends with a woman, I become selfish and tyrannical.
Humans call animals 'dumb'... after they robbed their entire own precious world. They are intelligent beings in their own right, and thoroughly self-sufficient... if not molested by humans. Yet, after millennia of slavery by selfish/callous humans they're made to look dumb! The 'superior species' in their situations would, too, appear 'dumb'.
Our object now, as then, is to vindicate the principles of peace and justice in the life of the world as against selfish and autocratic power, and to set up among the really free and self-governed peoples of the world such a concert of purpose and of action as will henceforth insure the observance of those principles.
There are three kinds of love;
unselfish, mutual, and selfish.
The unselfish love is of the highest kind;
The lover only minds the welfare of the beloved and does not care for his own sufferings.
In mutual love the lover not only wants the happiness of his beloved;
but has an eye towards his own happiness also. It is middling.
The selfish love is the lowest. It only looks towards its own happiness,
no matter whether the beloved suffers weal or woe.
