I want to take a look at the history of philosophy. I would say it's a look at the history of "philosophy of mind", but it covers more than that. I want to look at the points throughout history where a shift was made, to the using of terms and concepts that had never been used before. I want to do this because I want to see if any of them were wrong turns, that have changed philosophy for the worse. If it's true that some of these "turns" were bad ones, I don't want it to appear as though the philosopher(s) did something wrong, or as if it shouldn't have happened. After all, how can we learn from a mistake we never make? How, in turn, can we call something a mistake, if it is what arose necessarily from the questions being asked at the time?
