Proof of an External World, by G.E. Moore

Skepticism believes that there is no way to prove that things exist outside of us. As skeptics think that we can not distinguish between dreams and reality, I think the real thing is probably the creation of our thoughts, and we think that it is like the brain sitting in a big bucket It's simple. Let's connect to the machine to simulate the perfect performance in reality, let's live the "brain" in it 1 An excerpt from the same-name article "certificate of the outside world", GE

I examined some responses to the skeptical challenges presented in Part 2. In particular, we saw four answers: (1) Descartes Cogito, (2) GE. "Proof" to Moore's outside world, (3) Dretsk denies cognitive closure, and (4) David Lewis's contextualism. After considering the strengths and weaknesses of these proposed solutions, we review the question whether skepticism is so bad or not and draw a conclusion. This course concludes with a discussion of why we have the concept of knowledge. If there is no concept of knowledge we are accustomed to, what kind of life will it be? Does this gap in our cognitive economy affect widespread or is our life as generic as that? In order to better understand if the concept is important or important, we will consider what kind of life can exist without knowledge of knowledge.

Moore 's "evidence of the outside world" was created for the purpose of the soul, aimed at solving the "philosophical scandal" of Immanuel Kant. Obviously not enough for Kant and other philosophers. I believe the belief he said is true common sense, I believe in existence, and many other examples of congenital knowledge.

A new approach to protect Moore's common sense is also evident in his most famous thesis, the proof of the outside world (Moore 1939). Here, after considerable effort to understand the meaning of "external object" as "there is something that is not dependent on our experience", Moore said that the perfect idea of ​​the existence of such objects in this way It can be proved that it can prove it. The hand is "a CS proposition with a common meaning, use it according to this meaning, and the hand to be examined is enough to prove that the proposition is true - on the other hand there is certainly a hand The hand is matter matter, and matter matter is according to the usual meaning of "physical object" is an external object
