What is now called and taught as the history of philosophy is not very useful because it's not the actual history of philosophy, academic or otherwise. You learn mostly what little of say, 19th century philosophy we now have respect for regardless of whether that century even knew that thinker was alive. The context, mostly of "greats" that we now think are horse dung, is never given. Knowing how thinkers (and the crowds that love them) went badly wrong would be useful, but is rarely taught. Both the now-highly thought of and then-highly-thought-of are worth some attention.
