On free spirits ...

“He is called a free spirit who thinks differently from what, on the basis of his origin, environment, his class and profession, or on the basis of the dominant views of the age, would have been expected of him. He is the exception, the fettered spirits are the rule …. what characterizes the free spirit is not that his opinions are the more correct but that he has liberated himself from tradition, whether the outcome has been successful or a failure. As a rule, though, he will nonetheless have truth on his side, or at least the spirit of inquiry after truth: he demands reasons, the rest demand faith.”

(Friedrich Nietzsche, Human, All Too Human. §225. Trans. R. J. Hollingdale.)
