As long as justice and injustice have not terminated their ever renewing fight for ascendancy in the affairs of mankind, human beings must be willing, when need is, to do battle for the one against the other.

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.
