Since the emergence of human societies, people have continually changed, and members of these societies have come to view themselves as elevated and exceptional human beings. Yet, regardless of how strongly belonging to a particular society can enhance the collective self-image of its citizens, they do not necessarily regard members of their own society as fundamentally different. Rather, it is foreigners who undergo the most profound transformation in perception.

In his book The Human Swarm: How Our Societies Arise, Thrive, and Fall, translated by Nayef Al-Yassin, Mark W. Moffett seeks to answer a fundamental question: Why have humans alone managed to achieve a level of social organization unparalleled among other species?

Across two parts comprising 680 pages, the author presents a range of research-based insights into the origins, development, and flourishing of peoples and societies. Through 27 chapters, he explores topics including belonging and recognition, societies and identity, nomadic life, settlement, the deep history of anonymous human societies, the perception of others, putting relatives in their proper place, peace and conflict, mastering the art of playing with others, the life cycle of societies, the transition from tribes to nations, the inevitability of societies, and many other themes.

The book explores human society from its earliest origins to the great civilizations that exist on our planet today. It demonstrates how humans have succeeded in establishing and maintaining societies of unprecedented size and complexity in the animal world.

Moffett builds his book around two central ideas. The first is that human societies and social insect societies have more in common than we might think—or perhaps would like to believe. The second is the unique and complex nature of human identity, which determines who belongs to our societies and who is considered an outsider. The significance of this second idea lies in the fact that other animals that form societies, such as elephants and primates, rely on individual recognition. As a result, the size of their societies remains limited by this requirement, generally to around 200 individuals. Humans and social insects, such as ants, however, possess the ability to live in anonymous societies, allowing their communities to reach enormous sizes without splitting apart or collapsing.

Moffett argues that the emergence of agriculture was a stabilizing force, while the accumulation of property and advances in technology contributed to the stability and organization of societies. Linguistic diversity is also one of the most prominent markers of human identity, with most societies possessing their own languages. The author also examines membership in a society as a defining component of our sense of self. Throughout The Human Swarm, his arguments and questions move between natural history, prehistory, and the turbulent trajectory of civilizations—from the mud walls of Sumer to the vast digital world of Facebook—while exploring themes of coexistence, peace, and communication.

In the book, Moffett takes readers on a comprehensive and chronologically structured journey through humanity’s deep history, from primates to hunter-gatherers. Along the way, he draws on a range of related fields of knowledge, including archaeology, anthropology, ethnology, linguistics, psychology, and other disciplines.
