The philosophy department in Edinburgh is in David Hume tower; the philosophy faculty at Cambridge is in Sidgwick Avenue. In one way, no competition. Everybody (who's anybody) has heard of Hume, whereas even the anybody who's anybody may not have heard of Sidgwick. Yet in another way, Sidgwick wins this arcane contest. For if David Hume, contradicting the Humean theory of personal identity, were to return to Edinburgh, he would not recognize the tower. Whereas, if someone with more success in rearousing spirits than Sidgwick himself had could now produce him, Sidgwick would know the avenue. For he planned it; he partially paid for it; and he pushed it past the local opposition. He was its creator. And creator not just of the avenue: if Sidgwick is not quite the only begetter, it was he more than anyone who was responsible for building the school of philosophy in Cambridge which is being celebrated in this series of articles.
