This quotation is from a rather outspoken mathematician named Scott Buchanan, who has studied the style of human thought right along with its mathematical accomplishments. It is meant to describe our style of thinking when approaching mathematics. Yet it seems to me that it has a larger meaning: that it applies to the human style of thought when approaching any problem. Buchanan is telling us that when we are confronted with a problem and a possible solution and we cannot find our way to the solution, we have a tendency to believe in the solution out of pure frustration, or perhaps just wishful thinking.
