Sometimes, rarely, people experience something that could be called, for want of a better term, a quasi-Eureka moment. It isn’t that thing that made Aristotle leap out of his bath. It isn’t the answer. It isn’t there in black and white, in everything but the fine detail. What it is is a sudden switch in the way some problem, or things in general, are perceived. It’s the possibility of Eurekas to come. It’s the realization that there’s an entirely different range of options available from those one knew existed until that very moment.
