Moore’s “Proof of an External World” I believe that philosopher G.E. Moore’s “Proof of an External World” was somewhat successful in explaining there being an external world, however I have reason to believe that his proof cannot be taken for granted by using logic and physics. While there are flaws to his argument, he responds to those flaws with a rebuttal, and makes the person think if they can be certain about anything in existence. Moore’s argument can be simply put that; P1) he has a right hand and he has a left hand, P2) both of the hands are external objects in the world, C) An external world exists. Moore believes this is a legitimate argument based on his criteria for a proof. The first requirement is that the premises must be different from the conclusion. The second requirement is that the premises must be demonstrated. The third requirement is that the conclusion must follow the premises. Moore also notes that there may other requirements that he does not even know that could be needed to make a proof. However, he does go on to say we all take proofs such as this to be conclusive proofs. He also gives an example showing how you cannot truly be certain about things to know them, but you might be certain which means it might be a proof. As I stated earlier, I believe he is somewhat successful in explaining his proof, but I have reason to believe that his proof cannot be taken for granted. My example involves physics and perception. Moore doesn’t take into account that we may perceive things differently than they truly are. Because Moore uses his hands as an example I will relate my example to his as well. As we all know, everything as we know it is made up of atoms. These atoms are made up of neutrons and protons, which have space in between them. This means that all solid objects are made up of a loose cluster of attractions that
