The philosophy of Arthur Schopenhauer, which we’ve been discussing for several weeks now, isn’t usually approached from the angle by which I’ve been approaching it—that is, as a way to talk about the gap between what we think we know about the world and what we actually know about it. The aspect of his work that usually gets all the publicity is the ethical dimension.
That’s understandable but it’s also unfortunate, because the ethical dimension of Schopenhauer’s philosophy is far and away the weakest part of it. It’s not going too far to say that once he started talking about ethics, Schopenhauer slipped on a banana peel dropped in his path by his own presuppositions, and fell flat on his nose. The banana peel in question is all the more embarrassing in that he spent much of the first half of The World as Will and Representation showing that you can’t make a certain kind of statement without spouting nonsense, and then turned around and based much of the second half on exactly that kind of statement.
Let’s review the basic elements of Schopenhauer’s thinking. First, the only things we can experience are our own representations. There’s probably a real world out there—certainly that hypothesis explains the consistency of our representations with one another, and with those reported by (representations of) other people, with less handwaving than any other theory—but all the data we get from the world out there amounts to a thin trickle of sensory data, which we then assemble into representations of things using a set of prefab templates provided partly by our species’ evolutionary history and partly by habits we picked up in early childhood. How much those representations have to do with what’s actually out there is a really good question that’s probably insoluble in principle.
