“370. But more correctly: The fact that I use the word "hand" and all the other words in my sentence without a second thought, indeed that I should stand before the abyss if I wanted so much as to try doubting their meanings — shows that absence of doubt belongs to the essence of the language-game, that the question "How do I know…"”

Assorted Themes, On the Meaning of Life

Source: What is Property? (1840), Ch. I: "Method Pursued in this Work. The Idea of a Revolution"
Context: If I were asked to answer the following question: What is slavery? and I should answer in one word, It is murder, my meaning would be understood at once. No extended argument would be required to show that the power to take from a man his thought, his will, his personality, is a power of life and death; and that to enslave a man is to kill him. Why, then, to this other question: What is property! may I not likewise answer, It is robbery, without the certainty of being misunderstood; the second proposition being no other than a transformation of the first?
I undertake to discuss the vital principle of our government and our institutions, property: I am in my right. I may be mistaken in the conclusion which shall result from my investigations: I am in my right. I think best to place the last thought of my book first: still am I in my right.
