Then he said that "I showed this existence" by reaching out that "This is a hand". Moore will then boldly examine the reason why everyone makes such a reasonable claim in the example of his hand. Wittgenstein praised the claim that Moore is doing one hand, but Wittgenstein uses the view that the individual believes that the assertion he knows is questionable. More, you may say that he is challenging Moore's approach to better responding to skepticism. He starts this by pointing out obvious facts and arguments may not be that effective if your discussion relies on assertions like "This is a hand".
In this section, we will focus on Wittgenstein's "certainty" content. Certainty is the main epistemological study of Wittgenstein. It includes 676 short comments on beliefs, certainty, and most importantly the knowledge and topics being claimed to be known. These remarks are greatly hinted by two articles by G.E. Moore: "Advocacy of Common Sense" (DCS) and "Certificate of the External World" (PEW), so I will explain the various aspects of these papers, especially Wittgenstein's paper. answer
Since the 20th century, many philosophers have denied the idea that knowledge is a state of mind. For example, Ludwig Wittgenstein (1889-1951) stated "About certainty" in 1969, "Knowledge" and certainty belong to different categories. They are not two mental states like guess and affirmation. "A philosopher who denies knowledge usually points out that it is a characteristic of a state of mind such as doubt and suffering, and in those conditions they are saying that they are above them I know something like this and I doubt that everyone knows it.
