We imagine that human nature doesn't change. We like to say that but I don't think it's true because we have, in the course of the centuries, altered ourselves.

The only thing that one really knows about human nature is that it changes. Change is the one quality we can predicate of it. The systems that fail are those that rely on the permanency of human nature, and not on its growth and development. The error of Louis XIV was that he thought human nature would always be the same. The result of his error was the French Revolution. It was an admirable result.

“One can only describe the human but can never define it because humans are complex in their nature.”

One can only describe the human but can never define it because humans are complex in their nature.

Of course, when I say that human nature is gentleness, it is not 100 percent so. Every human being has that nature, but there are many people acting against their nature, being false.

Really I don't like human nature unless all candied over with art.
