The history of the human race.

The Cognitive Revolution

  • Homo sapiens succeeded through cooperation enabled by shared myths and language.
  • Cognitive changes allowed the creation of imagined realities like religion, corporations, and nations.
  • These shared beliefs enabled large groups to function beyond natural group size limits.
  • Sapiens outcompeted other humans not through strength, but through communication and flexibility.
  • Foragers were more skilled as individuals, but modern humans dominate collectively.

The Agricultural Revolution

  • Farming increased population but worsened individual well-being - “history’s biggest fraud.”
  • Small choices led to irreversible societal shifts, binding humans to hard labour and inequality.
  • Humans built imagined hierarchies (e.g., nobility, gender roles) to manage complex societies.
  • Writing and record-keeping changed human thought from holistic to bureaucratic.
  • Myths of equality and freedom coexist with real-world inequality and control.

The Unification of Humankind

  • History moves toward global unification through money, empires, and religion.
  • Money is a universal trust system; empires spread culture as well as domination.
  • Religious ideologies - monotheistic and polytheistic - help justify political and moral orders.
  • Humanism replaced gods with the sacredness of Homo sapiens, in liberal and socialist forms.
  • Science now questions human uniqueness, linking behaviour to biology and memes.

The Scientific Revolution

  • Science thrives by embracing ignorance, testing ideas, and applying them to gain power.
  • It is deeply intertwined with empire and capitalism - funding, exploration, and expansion.
  • Capitalism reframed greed as socially beneficial and drove global economic growth.
  • The Industrial Revolution was really a revolution in energy and productivity.
  • Consumerism and capitalism reinforce each other - elites invest, the masses buy.

The Future

  • Human happiness depends more on expectations and meaning than on wealth or comfort.
  • Buddhism and science both challenge the pursuit of feelings as a path to happiness.
  • Human-engineered evolution may soon replace natural selection (via bioengineering, AI).
  • Ethics and identity will be challenged by enhanced bodies, brains, and artificial minds.
  • Scientific projects for health or longevity justify disruptive innovation - whether we’re ready or not.
