G. E. Moore, The Early Essays, edited by Tom Regan, Temple University Press (1986). And for the hell of it, and for my own clarification, here they are in symbols. Here is one way to think about it: 1. In holding up his hand and saying “here is a hand”, he demonstrated the extremism of the claim that maybe he did not know it after all. In assuming that he knows that “here is a hand,” he is thereby assuming the existence of an external world, because to know something is to believe it (for appropriate reasons) and for it to be true. The conclusion must be different than the premise(s). Which one is it? Moore is claiming to give a proof of the external world here, and a proof is just a certain sort of argument. 142. The aim of this paper is to assess Moore"s Proof of an external world, in light of recent interpretations of it, namely Crispin Wright"s (1985) and James Pryor"s (unpublished). But I still want to side with Moore, because the deeper point he is making is that we do know things, and we know that we know them, but we do not know exactly how we know them, so we can never prove that we do. It is what has come to be known as a “Moorean fact”: I can be sure that I have two hands in front of me, or just I have two hands in front of me. This is the best explanation of our experiences. Start studying Moore Proof of an External World. It looks like it’s back to square one: we cannot prove which (P2) is true. Despite what I said in my last post about being enticed into the world of sense, reference, descriptions, rigid designators and necessary a posteriori truths, I’m beginning with scepticism after all. ( Log Out / Three things are necessary for a proof to be considered rigorous: The premises must be known. Moore’s essay, Proof of an External World, from 1939. Although the argument seems simple at first, its strength makes itself apparent in the attempts to offer rebbutals. No: Moore says that we can know without being able to prove that this knowledge is possible. I argue that neither Wright's nor Pryor's readings of the proof can explain this paradox. Moore’s standing as a central figure at the dawn of an-alytic philosophy rests in part on the credit his early work is given in the demise of neo-Hegelian monistic idealism, whose influence was extensive in Anglophone philosophy in the late Moore gives in his 1939 paper, “Proof of an External World,” originally delivered to the British Academy. Early on in his explanation of the proof, in demonstrating its rigour, he says: “I certainly did at the moment know that which I expressed…”, But later he admits that, although he has evidence that he is not dreaming, “that is a very different thing from being able to prove it.”. In this chapter, Stroud analyses the response to scepticism given by G. E. Moore in his famous ‘Proof of an External World’.Moore seeks to prove that the proposition that there are no external things is in fact false. This is the best explanation of our experiences. The standards of rigour are that the premise is different from the conclusion; that he knows the premise rather than simply believing it; and that the conclusion follows from the premise. ∴ I cannot be sure that I have two hands in front of me, (P1) If I cannot tell the difference between waking and dreaming, then I cannot be sure that there are two hands in front of me It looks like it’s back to square one: we cannot prove which (P2) is true. understand 'proof of an external world' as includ- ing a proof of things which I haven't attempted to prove and haven't proved. This means that the conclusion is assumed in the premise, so the argument begs the question. Written by people who wish to remain anonymous Proof of an External World is not what it proposes to be. some things external to our minds.) So he is not directly addressing scepticism on its own terms. And for the hell of it, and for my own clarification, here they are in symbols. In ‘Proof of an External World’, Moore seeks to prove the existence of things ‘external to our minds’ (Moore 1959). Change ), You are commenting using your Twitter account. A new reading of G. E. Moore’s “Proof of an External World” is offered, on which the Proof is understood as a unique and essential part of an anti-sceptical strategy that Moore worked out early in his career and developed in various forms, from 1909
