What is libertarianism?

I’m very sympathetic to libertarian thought, and have been for years. However, I don’t classify myself as a libertarian for various reasons. Nevertheless, what is libertarianism? Essentially, it’s a political philosophy advocating: maximising individual freedom; minimising the role of the state; and the belief in free will. I have some conflict with the first bullet, but the third bullet is the one that gets me. I am on the fence about free will. Could it be that free will is largely an illusion and that a lot of our decisions are made based on factors beyond our control, as noted by thinkers such as Scott Adams and Steven Pinker? I don’t know. Martin van Staden, from the Free Market Foundation, chatted to me about all of this. Watch the video
