A society is a group of people who share a territory and a culture — and Gerhard Lenski found that the most useful way to sort societies is by their technology, meaning simply how they get their food. Change that, and everything else moves with it: how many people can live together, how much wealth can be stored, and how unequally it ends up divided. Step from foraging to the information age, then learn to recognize each type on sight.

Where sociologists take it next.Functionalism reads this sequence as growing interdependence: Durkheim's mechanical solidarity, where people cohere because they are alike and share one moral outlook, gives way to organic solidarity, where they cohere because they need each other's specialized work — and when that shift outruns the norms that govern it, he expected anomie, a condition of normlessness. Merton would separate the manifest function of the plow (more grain) from its latent ones nobody intended: cities, standing armies, hereditary elites. Conflict theory asks a sharper question of the very same list — the moment a surplus exists, someone can control it. Marx traced that from private property to class, and finally to the split between those who own the means of production and those with only their labor to sell, with alienation as the worker's lived experience of the factory. Weber read the modern end of the sequence as rationalization: calculation and efficiency spreading through bureaucracy until they harden into what he called an iron cage. Symbolic interactionism works at eye level on the same material: Cooley's looking-glass self forms differently in a band of sixty who have known you since birth than in a city of strangers, and Goffman's staged presentation of self presupposes exactly the audience of strangers that industrial cities produced — while Mead would note that the generalized other a child internalizes is assembled out of whichever society happens to be doing the raising. Comte named the discipline in the middle of the industrial upheaval, and Mills supplies the connective tissue: losing your job to automation feels like a personal trouble, but it is a public issue with a date and a technology attached.
Three things students get wrong. First, this is not a ladder every society climbs. Pastoral and horticultural societies arose at the same time in different environments — dry grassland versus fertile soil — and neither descends from the other; ranking them primitive-to-advanced smuggles in exactly the ethnocentrism sociology exists to catch. Second, more technology has not meant more equality. The most egalitarian societies on record are the ones with no surplus at all; inequality entered human life alongside storable wealth, not alongside human greed. Third, postindustrial does not mean industry ended — manufacturing was automated and relocated, which is a change in where and by whom, not a disappearance.
