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.
