This text, an excerpt from Byron Reese's book "We Are Agora," explores the nature of life, from the fundamental cell to complex organisms and even planetary systems. Reese examines what defines life, discussing concepts like emergence and the difficulty in creating a universal definition. He introduces the idea of superorganisms, such as beehives and the hypothetical Gaia, and analyzes the essential forces—energy, information, communication, cognition, specialization, and technology—that drive their complexity and emergent properties. The book then applies these concepts to humanity, proposing that humans collectively form a planetary superorganism called Agora, whose "cells" are people and "hives" are cities, arguing that our increasing specialization and interconnectedness demonstrate this collective entity.
