John Herschel was born OTD in 1792.
His 1831 Preliminary Discourse launched a flowering of reflection on the aims and methods of science among British thinkers that was so rich and influential that Charles Sanders Peirce would later dub it “the Age of Method.”

Thanks! I focused on James, but as you say, could just as easily have talked about Dewey.

What if Humans Were Raised Like Bees? Charles Darwin and the Evolution of Morality
By Greg Priest Read the full companion article in this quarter’s Journal of the History of Ideas. A new biography of Charles Darwin is coming out. Styled as a “radical reappraisal,” the book, by...
Darwin’s Descent of Man launched OTD in 1871. In it, D finally made explicit what had been obvious, if unstated, in the Origin: humans had evolved.
And not merely bodily. Our minds, even our moral codes, evolved from animal sources.

“There is no canonical way to think of our own past. In the endless quest for order and structure, we grasp at whatever picture is floating by and put our past into its frame.”

I take him to be suggesting that a search for invariance is in a sense a search for essence, and that undertaking such a search implies a belief that the essence thus discovered is in some sense more fundamental than the “accidental” sources of variation. Sounds a bit Platonic to me.

Plate of iguanodon teeth from Gideon Mantell, “Notice on the Iguanodon, a newly discovered fossil reptile, from the sandstone of Tilgate Forest, in Sussex,”Philosophical Transactions of the Royal Society of London, vol. 115 (1825), p. 186.
Gideon Mantell published his description of the iguanodon OTD in 1825.
He had originally thought that the fossil teeth on which he based his description were those of a giant crocodile, but later determined that the creature was an enormous herbivore.

Final stanza of the poem:
If you catch him,
hold up a flashlight to his eye. It’s all dark pupil,
an entire night itself, whose haired horizon tightens
as he stares back, and closes up the eye. Then from the lids
one tear, his only possession, like the bee’s sting, slips.
Slyly he palms it, and if you’re not paying attention
he’ll swallow it. However, if you watch, he’ll hand it over,
cool as from underground springs and pure enough to drink.
Elizabeth Bishop was born OTD in 1911.
She wrote the best poem ever inspired by a typo in a newspaper article—“man-moth,” when what was intended was “mammoth.”

“Reality, in its quantitative aspect, must be considered as a system of populations.… The general study of the equilibria and dynamics of populations … has probably reached its highest development in the biological study known as 'ecology,' [and] this name may well be given to it.”

Knowledge is not a body of consistent theories converging on truth. It is “an ever increasing ocean of mutually incompatible … alternatives, each single theory, each fairy tale, each myth … forcing the others into greater articulation.”

William James was born OTD in 1842.
As important as “pragmatism” to understanding James is “meliorism,” the idea that improving the world is possible, but not assured. We have to fight for it.

Wegener's (1915) depiction of the breakup of Pangaea. (a) the Carboniferous, (b) the Eocene, (c) today.
OTD in 1912, Alfred Wegener delivered a lecture propounding the theory that our modern continents were formed by the splitting and drifting apart of an ancient supercontinent, which he named Pangea.
Due to his failure to offer a plausible mechanism, he was widely ridiculed.

To call a car “dented” is to implicitly refer to an earlier undented state.
Stories “have a beginning, a middle, and an end. An [historical] explanation then consists in filling in the middle between the temporal end-points of a change.”
