Life with Intent: Rethinking Biological Agency

Quanta Magazine surveys whether ‘biological agency’—the idea that life acts with goals or reasons—is scientifically productive, weighing mechanistic, gene-centered explanations against views that organisms set proximal goals through context, learning, and interaction with their environment. The piece traces debates from Mayr and Monod to Baldwin’s effect and Lamarck, examines whether agency implies conscious deliberation, and argues for developing a formal, testable theory of agency that could unify biology with development, evolution, and future artificial agents.
