The verdict
So who was greater? The honest answer: they're not strictly comparable. By raw IQ proxy, Aristotle edges out. By measurable, lasting influence in their respective field, both are anchors of the human record. If you have to pick one to bet civilization on, pick the one working on the problem you care about.
