哲學家 維根斯坦 在《邏輯哲學論》的序言中說：「我這本書有兩個部分：一個是我有寫的那部分，另一個是我沒有寫的那部分。我沒有寫的部分，比有寫的部分，更加重要。」

他是意思是，他的書的最大價值，不在於書中寫了什麼，而在於書中寫的東西，可以引發到讀者思考什麼。讀者最受用的，將會是讀者自己的思想。只有讀者自己的思想，最終屬於讀者自己，永不忘記。

You won’t — I really believe — get too much out of reading it. Because you won’t understand it; the content will seem strange to you. In reality, it isn’t strange to you, for the point is ethical. I once wanted to give a few words in the foreword which now actually are not in it, which, however, I’ll write to you now because they might be a key for you: I wanted to write that my work consists of two parts: of the one which is here, and of everything which I have not written. And precisely this second part is the important one.
