I told Chris the other night that Phaedrus spent his entire life pursuing a ghost. That was true. The ghost he pursued was the ghost that underlies all of technology, all of modern science, all of Western thought. It was the ghost of rationality itself. I told Chris that he found the ghost and that when he found it he thrashed it good. I think in a figurative sense that is true. The things I hope to bring to light as we go along are some of the things he uncovered. Now the times are such that others may at last find them of value. No one then would see the ghost that Phaedrus pursued, but I think now that more and more people see it, or get glimpses of it in bad moments, a ghost which calls itself rationality but whose appearance is that of incoherence and meaninglessness, which causes the most normal of everyday acts to seem slightly mad because of their irrelevance to anything else. This is the ghost of normal everyday assumptions which declares that the ultimate purpose of life, which is to keep alive, is impossible, but that this is the ultimate purpose of life anyway, so that great minds struggle to cure diseases so that people may live longer, but only madmen ask why. One lives longer in order that he may live longer. There is no other purpose. That is what the ghost says. — Zen and the Art of Motorcycle Maintenance
This gets at the heart of the materialist approach to life and the ultimate contradictions it entails. The materialistic approach is at its core nihilistic, meaningless, and leads to despair if one who follows it ultimately seeks to understand it.
