Monomath

It is not a refuge for self-indulgent monomaths to channelize their aggressions within a community of colleagues and students.

We don't like polymaths any more. Perhaps it's because even being a monomath is too difficult now; even specialists specialise only in a small subset of their specialty, and learning is an either/or business.

Posner first made his name as a monomath. “I had a very big intellectual commitment for many years to anti-trust law. I wrote a lot about that.” Eventually, though, the polymath rose to the surface and he put anti-trust behind him.
