F. Scott Fitzgerald

In Kyle’s corpus, F. Scott Fitzgerald appears almost entirely through a single recurring line — “The test of a first-rate intelligence is the ability to hold two opposed ideas in mind at the same time and still retain the ability to function.” It functions as Kyle’s standing epigraph for embracing nuance and holding tension rather than collapsing it. Faith is Not Blind quotes it for the “ideal vs. real” tension at the heart of mature faith; How To Take Smart Notes and Charlie Munger’s Charlie Munger — The Psychology of Human Misjudgment both surface it as a thinking habit.

The quote is most load-bearing in Kyle’s own essay drafts. In The Meme Economy - Research it is “the structural spine” — the two opposed ideas being “(1) factual reality matters, and (2) most of reality is dictated by what people decide to believe.” It recurs as the closing or organizing frame in It’s Time To Build… But Build What - Research, Embrace The Nuance - Research, The Hardening Of The Great Softening - Research, What’s In a Post-Mortem - Research, and Books 2.0 - Research. Across all of them Fitzgerald is invoked not as a novelist but as the patron saint of dialectical, two-things-at-once thinking.

Context: F. Scott Fitzgerald (1896–1940) was an American novelist of the Jazz Age, best known for The Great Gatsby. The “two opposed ideas” line comes from his 1936 essay “The Crack-Up.”
