A concise introduction to natural law ethics, this text introduces readers to the mainstream tradition of Western moral philosophy. Building on philosophers from Plato through Aquinas to John Finnis, Gomez-Lobo links morality to the protection of basic human goods - life, family, friendship, work and play, the experience of beauty, knowledge and integrity - elements essential to a flourishing, happy human life. Intended for students of ethics and natural law, this text makes arguments consistent with Catholic teaching but not based on theological considerations.
