Philosophy is a discipline which, perhaps more than any other, is preoccupied with its history. At the same time, this preoccupation has as much to do with maintaining and reclaiming traditions as with critiquing and transforming them. Some figures leave indelible marks on schools of thought, even while attributing credit to their forebears on whose shoulders they in turn innovate and critique. The legacy of these figures is instantiated through the generative role they play in inspiring new schools of thought. Such reception is by no means inherently positive. In fact, it is often disagreement rather than affirmation that sustains the lasting impact of an original thinker.
