Q. How can one recognize truth on our level? A. By coming to simple things. In simple things one can recognize truth; one can recognize what is a door and what is a wall, and one can bring every difficult question to the same thing. It means that you have to recognize a certain quality in quite simple principles and verify other things by these simple principles. This is why philosophy—just discussion of possibilities or the meaning of words—is excluded from this system. You must try to understand simple things, and you must learn to think in this way; then you will be able to bring everything to simple things. Take for instance self-remembering. You are given all the material; if you observe yourself, you will see that you did not remember yourself at that moment; you will notice that at some moments you remember yourself more and at some moments less, and you will decide that it is better to remember yourself. This means that you have found a door, that you see the difference between a door and a wall.
