Solitude is impractical, and society fatal. We must keep our head in the one and our hands in the other. The conditions are met, if we keep our independence, yet do not lose our sympathy.
A man's ethical behaviour should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.
Sympathy constitutes friendship; but in love there is a sort of antipathy, or opposing passion. Each strives to be the other, and both together make up one whole.
We find nothing easier than being wise, patient, superior. We drip with the oil of forbearance and sympathy, we are absurdly just, we forgive everything. For that very reason we ought to discipline ourselves a little; for that very reason we ought to cultivate a little emotion, a little emotional vice, from time to time. It may be hard for us; and among ourselves we may perhaps laugh at the appearance we thus present. But what of that! We no longer have any other mode of self-overcoming available to us: this is our asceticism, our penance.
In a cabinet of natural history, we become sensible of a certain occult recognition and sympathy in regard to the most unwieldy and eccentric forms of beast, fish, and insect.
