And They Lived Happily Ever After? — The History of Happiness and Human Well-Being Explained | Chapter 19 from Sapiens by Yuval Noah Harari

Has all of humanity’s progress actually made us happier? In Chapter 19 of Sapiens: A Brief History of Humankind, Yuval Noah Harari tackles this timeless question by exploring the relationship between wealth, power, and subjective well-being.

The Paradox of Progress: Are We Happier Now?

Harari argues that while the modern era has brought unparalleled wealth, longevity, and comfort, happiness has not necessarily followed. Studies in psychology and biology show that well-being is shaped more by expectations, perception, and biochemistry than by material gains. Our brains adapt to new comforts, raising the bar for satisfaction and leaving many perpetually unsatisfied.

Key Topics in Chapter 19

• Material Progress vs. Happiness: Economic and technological revolutions do not guarantee increased well-being.
• The Role of Expectations: Happiness is often determined by shifting standards, not absolute conditions.
• Biochemical Limits: Hormones and neurotransmitters (like serotonin and dopamine) set biological boundaries for joy and contentment.
• Buddhism vs. Liberalism: Competing philosophies on happiness—chasing pleasant feelings versus detachment from craving.
• Modern Discontent: Media, consumerism, and constant comparison fuel dissatisfaction in modern societies.
• Industrial Cruelty and Ethics: Harari notes the moral cost of progress for non-human animals in industrial agriculture.

Evolution, Psychology, and the “Happiness Set Point”

Drawing on evolutionary psychology, Harari explains the concept of a “happiness set point”—the tendency for people to return to a baseline of contentment (or discontent) regardless of external change. Ancient foragers, medieval peasants, and modern city dwellers have all faced different challenges, but no era has a monopoly on joy or misery.

Conclusion: Toward a History of Happiness

Chapter 19 of Sapiens urges historians and individuals alike to measure the true impact of progress not just in power and wealth, but in happiness and suffering.
