Marshalling insights from diverse sciences including physiology, comparative psychology, developmental biology, and evolutionary biology, the book provides an up-to-date survey of approaches to non-human organisms as agents, capable of performing activities serving their own goals such as surviving or reproducing, and whose doings in the world are thus to be explained teleologically. From an Integrated History and Philosophy of Science perspective, the book contributes to a better conceptual and theoretical understanding of organismal agency, advancing some suggestions on how to study it empirically and how to frame it in relation to wider scientific and philosophical traditions. It also provides new historical entry points for examining the deployment, trajectories, and challenges of agential views of organisms in the history of biology and philosophy.

This book will be of interest to philosophers of biology; historians of science; biologists interested in analysing the active roles of organisms in development, ecological interactions, and evolution; philosophers and practitioners of the cognitive sciences; and philosophers and historians of philosophy working on purposiveness and teleology.
