This splendid fable is the metaphorical representation of the process by which one moves from knowledge of the evanescent world of nature to knowledge of the more permanent things and finally to the source of all knowledge and being. Plato’s disciple Aristotle presented the same idea in a more prosaic manner, speaking of the transition from physics (the study of matter in motion) to mathematics (the study of numeric relations), and finally to metaphysics (the study of being as such). Neither philosopher despised what we would characterize today as science – in fact Aristotle can credibly claim the title as father of Western science – but they both recognized that there are things the sciences can’t know, things that are, in point of fact, the most important, lasting, and fascinating.
