Are you a determinist? Here's how you can tell

Would you say, with respect to any decision that you have made, that given the actual past, you could have done otherwise than what you did? Determinists may agree with the statement "I could have done otherwise," but what they mean is that if the past had been different, the act would have been different.  Libertarians say that even given the actual past, they could have done otherwise from what they did.
