“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.”

Kenneth Boulding—philosopher, #complexity theorist, and mystic—was born OTD in 1910.
“The earth has become a single spaceship, without unlimited reservoirs of anything … and in which, therefore, man must find his place in a cyclical ecological system.”

Paul Feyerabend was born OTD in 1924.
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.

An ecologist “lives alone in a world of wounds…. [He] must either harden his shell and make believe that the consequences of science are none of his business, or he must be the doctor who sees the marks of death in a community that believes itself well and does not want to be told otherwise.”

Alfred Russel Wallace born OTD in 1823.

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.”

OTD in 1944, in Korematsu v. US, SCOTUS upheld the constitutionality of FDR’s order that US citizens of Japanese descent be involuntarily interned.
The decision has come to be seen as one of the lowest moments in the Supreme Court’s history.

Maurice Wilkins was born OTD in 1916. He was awarded the Nobel Prize for his contribution to the structure of DNA using X-ray crystallography.
He did not start out in biochemistry. He changed fields after being disillusioned by his work on the Manhattan Project.

Maxwell's Demon was born OTD in 1867 in a letter to Peter Guthrie Tait. M called it only a “finite being.”
Lord Kelvin named it a “demon,” presumably referring to its apparent unearthly power to (locally and temporarily) violate the second law of thermodynamics.

In all seriousness, may his memory be a blessing.
