Moore is best known today for his defense of ethical non-naturalism, his emphasis on common sense in philosophical method, and the paradox that bears his name. He was admired by and influential among other philosophers, and also by the Bloomsbury Group, but is (unlike his friend and colleague Russell) mostly unknown today outside of academic philosophy. Moore's essays are known for his clear, circumspect writing style, and for his methodical and patient approach to philosophical problems. He was critical of philosophy for its lack of progress, which he believed was in stark contrast to the dramatic advances in the natural sciences since the Renaissance. He often praised the analytic reasoning of Thales of Miletus, an early Greek philosopher, for his analysis of the meaning of the term "landscaping." Moore thought Thales' reasoning was one of the few historical examples of philosophical inquiry resulting in practical advances. Among his most famous works are his book Principia Ethica, and his essays, "The Refutation of Idealism", "A Defence of Common Sense", and "A Proof of the External World".
He was president of the Aristotelian Society from 1918 to 1919.
G. E. Moore died on October 24 1958 and was interred in the Burial Ground of Parish of the Ascension, Cambridge, England. The poet Nicholas Moore and the composer David Moore were his sons. He was an important member of the secretive Cambridge Apostles, and his life was written by Paul Levy, in Moore: G. E. Moore and the Cambridge Apostles (1979).
Moore is also well-known for the so-called "open question argument," which is contained in his (also greatly influential) Principia Ethica. The Principia is one of the main inspirations of the movement against ethical naturalism (see ethical non-naturalism) and is partly responsible for the twentieth-century concern with meta-ethics.
Moore charged that most other philosophers who worked in ethics had made a mistake he called the "Naturalistic fallacy". The business of ethics, Moore agreed, is to discover the qualities that make things good. So, for example, hedonists claim that the quality being pleasant is what makes things good; other theorists could claim that complexity is what makes things good. With this project Moore has no quarrel. What he objects to is the idea that, in telling us the qualities that make things good, ethical theorists have thereby given us an analysis of the term 'good' and the property goodness. Moore regards this as a serious confusion. To take an example, a hedonist might be right to claim that something is good just in the case that it is pleasant. But this does not mean, Moore wants to insist, that we can define value in terms of pleasure. Telling us what qualities make things valuable is one thing; analyzing value is quite another.
Moore's argument for the indefinability of “good” (and thus for the fallaciousness of the “naturalistic fallacy”) is often called the Open Question Argument; it is presented in §13 of Principia Ethica The argument hinges on the nature of statements such as "Anything that is pleasant is also good" and the possibility of asking questions such as "Is it good that x is pleasant?" According to Moore, these questions are open and these statements are significant; and they will remain so no matter what is substituted for "pleasure". Moore concludes from this that any analysis of value is bound to fail. In other words, if value could be analyzed, then such questions and statements would be trivial and obvious. Since they are anything but trivial and obvious, value must be indefinable. Critics of Moore's arguments sometimes claim that he is appealing to general puzzles concerning analysis (cf. the paradox of analysis), rather than revealing anything special about value. Other responses appeal to the Fregean distinction between sense and reference, allowing that value concepts are special and sui generis, but insisting that value properties are nothing but natural properties (this strategy is similar to that taken by non-reductive materialists in philosophy of mind).
Therefore, we cannot define "good" by explaining it in other words, we can only point to an action or a thing and say "That is good." Similarly, we cannot describe to a blind man exactly what yellow is. We can only show a sighted man a piece of yellow paper or a yellow scrap of cloth and say "That is yellow."
Moore distinguished his view from the view of deontological intuitionists, who held that "intuitions" could determine questions about what actions are right or required by duty. Moore, as a consequentialist, argued that "duties" and moral rules could be determined by investigating the effects of particular actions or kinds of actions (PE § 89), and so were matters for empirical investigation rather than direct objects of intuition (PE § 90). On Moore's view, "intuitions" revealed not the rightness or wrongness of specific actions, but only what things were good in themselves, as ends to be pursued.
In addition to Moore's own work on the paradox, the puzzle also inspired a great deal of work by Ludwig Wittgenstein, who described the paradox as the most impressive philosophical insight that Moore had ever introduced.
According to Moore, a moral actor cannot survey the “goodness” inherent in the various parts of a situation, assign a value to each of them, and then generate a sum in order to get an idea of its total value. A moral scenario is a complex assembly of parts, and its total value is often created by the relations between those parts, and not by their individual value. The organic metaphor is thus very appropriate: biological organisms seem to have emergent properties which cannot be found anywhere in their individual parts. For example, a human brain seems to exhibit a capacity for thought when none if its neurons exhibit any such capacity. In the same way, a moral scenario can have a value far greater than the sum of its component parts.
To understand the application of the organic principle to questions of value, it is perhaps best to consider Moore’s primary example, that of a consciousness experiencing a beautiful object. To see how the principle works, a thinker engages in “reflective isolation”, the act of isolating a given concept in a kind of null-context and determining its intrinsic value. In our example, we can easily see that per sui, beautiful objects and consciousnesses are not particularly valuable things. They might have some value, but when we consider the total value of a consciousness experiencing a beautiful object, it seems to exceed the simple sum of these values (Principia 18:2).
