Ludwig WittgensteinWhen philosophers use a word--"knowledge," "being," "object," "I," "proposition," "name"--and try to grasp the essence of the thing, one must always ask oneself: is the word ever actually used in this way in the language-game which is its original home?--What we do is to bring words back from their metaphysical to their everyday use.
Ludwig WittgensteinPhilosophy just puts everything before us, and neither explains nor deduces anything.-Since everything lies open to view there is nothing to explain
