Praxis

Praxis means taking what you believe and acting on it. Specifically, it means action taken to improve society.

It comes from a Greek word for action. The word was created by August Cieszkowski. The word is also an important part of Karl Marx's early works, where he defines it as unique to human beings.

Praxis, to many anarchists, is more important than its opposite, theory-- taking action to make society better is more important than thinking all the right thoughts.
