II. The Logic of Thought and the Logic of Reality

Let me make clear to you by a quite trivial, simple comparison, how the ordinary thinking that runs on purely abstract lines may fall into error. One thought is supposed to follow from another. The error is that if people see: As a thought it does not follow—they concluded that it must be false, while all the time from the point of view of reality it still may be perfectly true. The consequences in reality are not always the same as the consequences in mere thought; the Logic of Reality is a different thing from the Logic of Thought.
