"Our morality seems to be only a check on the ultimate domination of force, just as our politeness is a check on the impulse of every pig to put his feet in the trough."

Why should we desire the destruction of human passions? Take passions from human beings and what is left? The great object should be not to destroy passions, but to make them obedient to the intellect. To indulge passion to the utmost is one form of intemperance - to destroy passion is another. The reasonable gratification of passion under the domination of the intellect is true wisdom and perfect virtue.
