A Review of the Systems of Ethics Founded on the Theory of Evolution

This volume offers a systematic survey of ethical systems that root moral thinking in the theory of evolution. Drawing on the works of thinkers from Darwin and Spencer to von Gizycki and Höfding, the author maps out how evolutionary concepts such as variation, competition, and adaptation have been woven into philosophical arguments about right and wrong. The opening sections also lay out a clear preface that acknowledges the tangled web of influences shaping any intellectual project.

Beyond mere cataloguing, the book engages directly with the classic a‑priori objections to evolution‑based ethics, offering reasoned refutations that make the case for their relevance today. Detailed chapters trace the development of key ideas—heredity, habit, reason, and the struggle for existence—showing how each has been interpreted and contested across different schools. The treatment balances scholarly precision with an accessible tone, inviting listeners to follow the debate without requiring a background in biology or philosophy.
