The Unity of Science : A Sketch (Classic Reprint)

Explore how science tries to answer life’s big questions and why experiments alone can’t settle them.

This concise guide collects the core ideas of a psychologist of biology who questions how we understand nature, science, and the purpose of living things. It traces debates from early philosophy to modern embryology, and explains how form, function, and environment shape our view of life. This edition frames a long-running inquiry with clear, practical reasoning. It emphasizes the limits of experiment, the role of theory, and the way new findings—from embryology to physiology—inform our picture of nature. Throughout, it connects ideas from Kant to contemporary biology, offering a readable, balanced survey for curious readers.
