1. History needn’t be identity pageantry. Put universal human nature back at the centre: slowly evolving, cross-cultural, and—while hard to define—real enough to guide analysis.

2. Humans share core traits: ambition, empathy, foresight, morality, complex personality, dignity. Newborns are primed for number, language, probability, and social sense—within our species’ genetic bounds.

3. Individuality is prior. Every culture names persons and balances autonomy with fate. We’re social—but sociability is taxing. Privacy and solitude restore attention and self-command.

4. Death is the animal terminus; culture transmutes terror of death. Hope, faith, art, literature, religion, martyrdom, “hero and patriot”—all ways to deny or redeem mortality’s sting.

5. Happiness demands freedom *and* security. Practical reason—steered by emotion and moral instinct—seeks workable solutions. Good sense, the power to judge, is widely shared.

6. Emotions span a stable range (joy, anger, anxiety, love, grief, fear, hate). We can modulate them—up to the strength of the stimulus. To a tickle we differ; to a red-hot iron, alike.

7. Morality is innate. Cultures often code it via religions, but dogma isn’t the source. Across peoples: fairness, gratitude, kindness admired; cruelty, fraud, murder condemned—save for strained “justifications.”

8. Conflict springs from competition, fear, and reputation. Humans aren’t built for killing; massacres arise when risk is low and victims dehumanized. Drill and coercion override the soldier’s self-preserving instincts.

9. Most people recoil from cruelty—yet obey authority. Milgram holds up cross-culturally. Duty, honour, piety can eclipse visceral revulsion when atrocity feels obligatory to avert catastrophe.

10. We crave belonging. Norms are policed; compliance is often performative. Reasoning is built to persuade allies and resist opponents—yet still manages to solve problems.

11. Age grades appear everywhere. Young, unattached men form bold bands; fortune often favors their audacity. Much historical drama is youth’s energy—sometimes brilliance, sometimes folly.

12. Pair-bonding is humanly typical; marriage (or equivalent) is near-universal and affective. Parenting rewires brains of mothers and fathers. Kin beyond early-life caregiving? Mostly metaphor and interest.

13. Sexual orientation isn’t chiefly socialized; biology matters. Trans identities likely existed in all societies (even without the word). Norms shape expression, not the basic pattern of desire/self.

14. Sex differences are modest but real; male variability is greater. Men commit more violent crime; women excel in people-work and dense friendship networks. Gender roles evolve in a “double helix,” not simple convergence.

15. Collective identities persist. Territory binds; so does hospitality to strangers. Humans readily form durable ties across language and appearance when reciprocity and safety are present.

16. Work divides labour roles, uses tools, and runs on reciprocity. Property attaches to effort; people intuit “value for contribution.” Quasi-markets thrive, but positional luxury distorts prices and fuels superstar premiums.

17. Hierarchies form fast. Good leaders earn “idiosyncrasy credits” and accept guidance in turn. Overreach triggers bottom-up counter-dominance. Glamour enthralls, but stable class-states rest on function and justice.

18. Class psychology justifies the status quo—till privilege detaches from service. Then resentment rises. History is a shifting orrery of human nature and social structure: misalignments, backlashes, re-embeddings, new equilibriums.
