Aristotle’s “Metaphysics” begins by saying that “All men by nature desire to know.” He, of course, regarded as “men” a select few — the Greek citizens — not the majority of the Greek people made up of slaves — beings who had allowed themselves to be conquered, inferior beings — much less the non-Greek barbarians. Perhaps the problem is precisely this: most of us must be descended from slaves, and as Will Durant put it, it must have been slavery that prepared us for the habit of toil. If this were not the case, we wouldn’t work so hard and think so little. Because when I look around me, I do not see many people interested in knowing. In fact, I see almost no one.
