So I have two cats. One is a British Shorthair named after the very English Philippa Foot. The other is an Ocicat named Catullus, after Gaius Valerius Catullus, an ancient Roman poet some of whose stuff is decisively Not Safe For Work. I often refer to the two as “the irrational animals” – as in “the irrational animals are hungry” or “thank you for taking care of the irrational animals” – but I suspect this is just an Aristotelian slur. They are probably more rational than I am, though I am surely smarter.
Can you be smarter but less rational? I hear epistemologists talk as if you can’t. But you can, easily. Consider a mentally healthy child of 11. Imagine the same child at 14. She has gotten smarter, but probably less rational.
