Socrates

The hottest love has the coldest end.

Do not do to others what angers you if done to you by others.

Remember that there is nothing stable in human affairs; therefore avoid undue elation in prosperity, or undue depression in adversity.

By all means marry; if you get a good wife, you'll be happy. If you get a bad one, you'll become a philosopher.

Death may be the greatest of all human blessings.
