Will Durant (via Farnam Street): history "repeats itself in the large" because **human nature changes with geological leisureliness**. Hunger, danger, and sex still trigger stereotyped responses. On human timescales the stock of motives is nearly fixed; only complex civilization multiplies unique situations and lets custom yield a little ground to reasoning. Geology and gradualism reinforce the same tempo. Darwin took slow earth-process change from Lyell and applied it to species. Institutions and temperaments that look permanent are usually grinding, not frozen, but they grind slower than news cycles, markets, or product roadmaps. Practical cut: expect recurring problem classes (status, scarcity, sex, fear). Do not expect the deep software of the species to patch on a quarterly release. Novelty lives in circumstance and tool, not in a new human. ## Cross-Domain Connections - [[Three Buckets of Knowledge]] — human history is the short third sample sitting on a nearly fixed organism - [[History Looks Inevitable Only in Hindsight]] — recurrence in the large is not a script for each year - [[Civilization Decline Is Leadership Failure Not Organism Death]] — fixed nature still leaves leadership free to fail adaptation ## Source - [[The Three Buckets of Knowledge]] — Farnam Street / Will Durant, 2016-02-16 — https://fs.blog/three-buckets-lessons-of-history/
