All men are, and should be regarded as, equal in public consideration and general value, but not so in personal behavior, character, and nature.
Equality as a universal concept is psychological and sociological in origin; behavior and character are entirely individual properties and pursuits.
You can make a man equal under the law, but you can make no law that will yield equals, great or small. You can declare a man equal in potential, but not so in action, ambition, or achievement. What a man eventually becomes, high or low, is entirely his own enterprise.
If you understand that then you will attempt great personal enterprises, if you do not apprehend this then no great enterprise will ever yield a profitable you.
