Spencer represents the ambitious Victorian attempt to ground morality in evolutionary science, a project Moore finds both influential and fundamentally confused. Where Spencer sees progress from natural facts to ethical conclusions, Moore sees a category mistake — the assumption that 'good' can be defined by any natural property, whether pleasure, evolution, or desire. Spencer matters to the book's middle arc because his theory forces Moore to articulate, with maximum precision, why the naturalistic fallacy is not a minor slip but the central error of modern ethics.
