“"Racism" is to the current era what "unAmericanism" was to the Fifties: a curse word that provides a handy substitute for logical thought.”

The Reactionary Temptation (2017)
Context: We are living in an era of populism and demagoguery. And yes, there’s racism and xenophobia mixed into it. But what we are also seeing, it seems to me, is the manifest return of a distinctive political and intellectual tendency with deep roots: reactionism.
Reactionism is not the same thing as conservatism. It’s far more potent a brew. Reactionary thought begins, usually, with acute despair at the present moment and a memory of a previous golden age. It then posits a moment in the past when everything went to hell and proposes to turn things back to what they once were. It is not simply a conservative preference for things as they are, with a few nudges back, but a passionate loathing of the status quo and a desire to return to the past in one emotionally cathartic revolt. If conservatives are pessimistic, reactionaries are apocalyptic. If conservatives value elites, reactionaries seethe with contempt for them. If conservatives believe in institutions, reactionaries want to blow them up. If conservatives tend to resist too radical a change, reactionaries want a revolution. Though it took some time to reveal itself, today’s Republican Party — from Newt Gingrich’s Republican Revolution to today’s Age of Trump — is not a conservative party. It is a reactionary party that is now at the peak of its political power.

White Liberals: We’re Not Racist (August 29, 2016)

Metaphysics, again, is the Dynamics of Thought; treats of the primary Powers of Thought; occupies itself with the mere Soul of the Science of Thinking. Metaphysical ideas stand related to one another, like thoughts without words. Men often wondered at the stubborn Incompletibility of these two Sciences; each followed its own business by itself; there was a want everywhere, nothing would suit rightly with either. From the very first, attempts were made to unite them, as everything about them indicated relationship; but every attempt failed; the one or the other Science still suffered in these attempts, and lost its essential character. We had to abide by metaphysical Logic, and logical Metaphysic, but neither of them was as it should be.
