關於語言與世界
"凡能說的,都能說清楚;凡不能談論的,就應該保持沉默。" (What can be said at all can be said clearly; and what we cannot talk about we must pass over in silence.)
"語言的界限即是世界的界限。" (The limits of my language mean the limits of my world.)
"世界的意義必定在世界之外。" (The meaning of the world must lie outside the world.)
"世界是事實的總和,而非事物的總和。" (The world is the totality of facts, not of things.)
