"But no. That was analogy rather than homology. What in the humanities they would call a heroic simile, if he understood the term, or a metaphor, or some other kind of literary analogy. And analogies were mostly meaningless—a matter of phenotype rather than genotype (to use another analogy). Most, of poetry and literature, really all the humanities, not to mention the social sciences, were phenotypic as far as Sax could tell. They added up to a huge compendium of meaningless analogies, which did not help to explain things, but only distorted perception of them. A kind of continuous conceptual drunkenness, one might say. Sax himself much preferred exactitude and explanatory power, and why not? If it was 200 Kelvin outside why not say so, rather than talk about witches’ tits and the like, hauling the whole great baggage of the ignorant past along to obscure every encounter with sensory reality? It was absurd. So, okay, there was no such thing as cultural polyploidy. There was just a determinate historical situation, the consequence of all that had come before—the decisions made, the results spreading out over the planet in complete disarray, evolving, or one should say developing, without a plan. Planless. In that regard there was a similarity between history and evolution, both of them being matters of contingency and accident, as well as patterns of development. But the differences, particularly in time scales, were so gross as to make that similarity nothing more than analogy again. No, better to concentrate on homologies, those structural similarities that indicated actual physical relationships, that really explained something. This of course took one back into science."
