“That all men are created equal does not mean that human beings are the same, or equal, in size, strength, beauty, virtue, or intelligence. There are obviously great differences in individual aptitudes and talents in sports, music, mathematics, speaking, and writing. They are also unequal in the virtues, among them courage, temperance, and justice. But as Jefferson once said, the fact that Sir Isaac Newton may be the most intelligent of living human beings does not give him any right whatever to my person or my property.”

Context: Some Socialists seem to believe that people should be numbers in a State computer. We believe they should be individuals. We are all unequal. No one, thank heavens, is like anyone else, however much the Socialists may pretend otherwise. We believe that everyone has the right to be unequal but to us every human being is equally important.

Context: Justice alone knows liberty, equality, and fraternity, and justice is a human virtue arising from man's human capacity to reason. We cannot make sense out of justice by looking at the moon or taking dope or building battleships. We can make sense out of justice by using our reason to discover that justice, like wisdom, is better than rubies.

“Human virtue should be equal to human calamity. ”
