The amount of eccentricity in a society has generally been proportional to the amount of genius, mental vigor, and moral courage it contained. That so few now dare to be eccentric marks the chief danger of the time.

John Stuart Mill was a philosopher who had a lot of thoughts about a lot of things. He was a big believer in the power of free will and self-determination. He also believed that there should be equality for all people, regardless of race, gender, or religion. He was a fan of utilitarianism, which is all about maximizing happiness for the greatest number of people. He was an advocate for individual liberty and democracy. In short, he was a pretty cool dude.
