G. E. Moore's seminal work challenges traditional ethical reasoning by distinguishing between questions of intrinsic value and questions of right action. Rejecting the naturalistic fallacy, Moore argues that 'good' is a simple, indefinable concept known through intuition. He contends that virtues and duties are means to good, not good in themselves, and that true belief significantly enhances the value of aesthetic and affectionate experiences.

In *Principia Ethica*, G. E. Moore seeks to establish a scientific basis for morality by clarifying the fundamental principles of ethical reasoning. He argues that the primary source of disagreement in ethics stems from a confusion between two distinct questions: first, what things ought to exist for their own sakes (intrinsic value), and second, what actions we ought to perform (duty). Moore asserts that the first question cannot be answered by evidence derived from other truths; rather, 'good' is a simple, unanalyzable property known only through self-evident intuition. Consequently, no other truth can prove or disprove that something is good. Regarding the second question, Moore contends that whether an action is right depends on causal truths about its results and ethical truths regarding intrinsic value. He famously critiques Hedonism and Virtue Ethics for committing the naturalistic fallacy, which involves defining 'good' in terms of natural properties like pleasure or virtue. Moore insists that pleasure and virtue are merely means to good, not good in themselves. He proposes that the only intrinsic goods are those involving aesthetic enjoyment and personal affection, where the object of appreciation must be truly beautiful and good. Moore further explores the role of true belief, arguing that believing an object of affection or beauty actually exists greatly increases its overall value. He defines beauty not by the feelings it produces but by the fact that contemplating it is an essential element of an intrinsically valuable whole. The book concludes by classifying great goods and evils, maintaining that many different things possess intrinsic value, rather than a single supreme good. Moore's rigorous logical analysis and his insistence on clear definitions have profoundly influenced modern moral philosophy, shifting the focus from metaphysical speculation to the logical structure of ethical concepts.
