#45 - Prof. Ian Morris : The Hidden Driver of Civilization: Energy & Human Values

We're joined by Ian Morris, British historian, archaeologist, and author of Foragers, Farmers, and Fossil Fuels

Ian’s central argument is both simple and radical: our beliefs about fairness, justice, hierarchy, equality, and even democracy are not timeless moral truths floating above history. They are shaped, constrained, and repeatedly reorganised by the ways societies extract and use energy. Across tens of thousands of years, he argues, there is a pattern beneath the chaos.

We dive into:

• Why hunter-gatherer societies tended to enforce radical egalitarianism

• How agriculture made hierarchy, inheritance, patriarchy, and forced labor more functional

• Why fossil fuel societies unexpectedly shifted back toward equality and democracy

• How values evolve like adaptations to changing material conditions

• Why the industrial age expanded the moral community

• Why inequality has begun rising again in recent decades

• Whether we are entering a fourth great shift in human values

• What energy transitions, AI, and new technologies could mean for democracy and civilisation

Key Takeaways from the Episode:

1. Human Values Are Not Fixed — They Adapt to Energy Systems

Morris argues that values are not random, but nor are they eternal. Over the long run, societies repeatedly develop moral systems that fit the material conditions created by how they capture energy from the world. This is not a metaphor. Morris means it in a nearly biological sense: values that match the prevailing energy regime help societies function, grow, and outcompete their neighbours — while mismatched values lead to stagnation, fragmentation, or collapse.

The mechanism is cultural evolution, operating on a civilisational timescale. A foraging band that tried to enforce agrarian-style kingship would fall apart. An industrial economy run on feudal principles would be outproduced by its rivals. Morris draws on decades of archaeological and anthropological data — compiled in his earlier work Why the West Rules — for Now — to show that this pattern holds across every major region and epoch. The implication is unsettling: the values we consider timeless may be temporary artefacts of the energy system we happen to inhabit.

2. Hunter-Gatherer Life Favoured Equality

In low-energy societies, people lived in small, mobile groups with little surplus and little material inheritance. Under those conditions, strong egalitarian norms were not idealistic luxuries — they were necessary for survival and cohesion. Morris draws on ethnographic evidence from groups like the Kung San of the Kalahari and the Hadza of Tanzania to show that foraging bands actively enforced equality through what Christopher Boehm calls “reverse dominance hierarchies” — systems in which the group collectively suppresses anyone who tries to accumulate too much power or prestige.

The tools were social: ridicule, gossip, ostracism, and in extreme cases, targeted violence. This was not paradise. Per capita rates of violent death among foragers were far higher than in modern states. But it was a system that worked under the constraints of low energy capture. When you cannot store surplus, when anyone can walk away from the group, when survival depends on mutual cooperation, radical equality is not a philosophy — it is an engineering requirement.

3. Agriculture Made Inequality Functional

Once farming emerged, people settled, accumulated land, inherited property, and built larger social structures. In that world, hierarchy, patriarchy, kingship, and coercive labour became easier to justify and more useful for organising society. Morris is careful to frame this not as moral decline but as adaptive reorganisation. Agrarian societies that developed clear lines of inheritance, centralised leadership, and mechanisms for extracting surplus labour — whether through serfdom, taxation, or slavery — were able to build irrigation systems, raise armies, and defend territory more effectively than those that did
