Original: (zh-CN) 什么是知识?自从有阶级的社会存在以来,世界上的知识只有两门,一门叫做生产斗争知识,一门叫做阶级斗争知识。自然科学、社会科学,就是这两门知识的结晶,哲学则是关于自然知识和社会知识的概括和总结。 note: "整顿党的作风"

Arthur Schopenhauer book Parerga and Paralipomena
Vol. 2, Ch. 22, § 257 "On Thinking for Yourself" as translated in Essays and Aphorisms(1970) as translated by R. J. Hollingdale
Variant translation: Just as the largest library, badly arranged, is not so useful as a very moderate one that is well arranged, so the greatest amount of knowledge, if not elaborated by our own thoughts, is worth much less than a far smaller volume that has been abundantly and repeatedly thought over.

Karl Popper (1902–1994) Austrian-British philosopher of science
Variant translation: The more we learn about the world, and the deeper our learning, the more conscious, clear, and well-defined will be our knowledge of what we do not know, our knowledge of our ignorance. The main source of our ignorance lies in the fact that our knowledge can only be finite, while our ignorance must necessarily be infinite.
Conjectures and Refutations: The Growth of Scientific Knowledge (1963)
Context: The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know, our knowledge of our ignorance. For this, indeed, is the main source of our ignorance — the fact that our knowledge can be only finite, while our ignorance must necessarily be infinite.
