Those who are unfamiliar with the name should read his biographical
In the modern high school and undergraduate curriculum, he will of course be given a sound-byte mention as the founder of 'Pragmatism', America's only contribution to Philosophy' or some such. But this will avoid mention, of course, of his 'cenopythagorean' ('New Pythagorean') metaphysick, or his discussion, like Guenon or Palamas, of the Triads. It will not mention his defence of Realism against Nominalism, or his Theism.
To pique your interest, I will link a bit of his 'Principles of Philosophy': link
Another gem of a passage: On Darwin ism
His discussion of Darwin's doctrine is very judicious, and better historically than many modern ones, that mistake it for the Neo-Darwinian synthesis of the 1930s (Darwin's hypothesis is, in contrast, both brilliant and scientifically wrong). See Jaap Bax for a modern discussion of the evolutionary emergence of nomos elaborated in Thomistic (and thus modern Aristotelian -- like Darwin against the liberals of the Scottish School -- terms).
