* This is the second part of a two-part installment of “Problematica.” In Part 1, I asked how “uniformitarianism” became associated with a view that had not originally been regarded as distinctly uniformitarian— the view that nature’s law are stable in space and time. This meaning-shift happened...
* This is the forty-fifth installment of my essay series “Problematica.” Once again, it’s about Charles Lyell and uniformitarianism, with guest appearances from Steve Gould, T. C. Chamberlin and Eduard Suess. Because it’s a bit long, I’ve split it into two parts. Part 1 introduces the question I...
