So long as we love we serve; so long as we are loved by others, I would almost say that we are indispensable; and no man is useless while he has a friend.
But if in your fear you would seek only love's peace and love's pleasure, then it is better for you that you cover your nakedness and pass out of love's threshing-floor, into the seasonless world where you shall laugh, but not all of your laughter, and weep, but not all of your tears.
The pleasures of love proceed successively from a distich to a quatrain, from a quatrain to a sonnet, from a sonnet to a ballad, from a ballad to an ode, from an ode to a cantata, and from a cantata to a dithyramb. A husband who begins with the dithyramb is a fool.
Love animals: God has given them the rudiments of thought and joy untroubled. Do not trouble their joy, don't harrass them, don't deprive them of their happiness, don't work against God's intent. Man, do not pride yourself on superiority to animals; they are without sin, and you, with your greatness, defile the earth by your appearance on it, and leave the traces of your foulness after you - alas, it is true of almost every one of us!
