In fact the whole passion ordinarily termed love (and heaven help me if I can think of any other term to apply to it) is of such exceeding triviality that I see nothing that I think comparable with it.
In the oasis complex, the thirsty man images he sees water, palm trees, and shade not because he has evidence for the belief, but because he has a need for it. Desperate needs bring about a hallucination of their solution: thirst hallucinates water, the need for love hallucinates a prince or princess. The oasis complex is never a complete delusion: the man in the desert does see something on the horizon. It is just that the palms have withered, the well is dry, and the place is infected with locusts.
All of us cherish our beliefs. They are, to a degree, self-defining. When someone comes along who challenges our belief system as insufficiently well-based - or who, like Socrates, merely asks embarrassing questions that we haven't thought of, or demonstrates that we've swept key underlying assumptions under the rug - it becomes much more than a search for knowledge. It feels like a personal assault.
