“I have been surprised at the unanimity with which the notion of the unacceptability of a Doomsday Machine is greeted. I used to be wary of discussing the concept for fear that some colonel would get out a General Operating Requirement or Development Planning Objective for the device, but it seems that I need not have worried. Except by some scientists and engineers who have overemphasized the single objective of maximizing the effectiveness of deterrence, the device is universally rejected. It just does not look professional to senior military officers, and it looks even worse to senior civilians. The fact that more than a few scientists and engineers do seem attracted to the idea is disquieting, but as long as the development project is expensive, even these dedicated experts are unlikely to get one under way.”

Be Here Now (1971)
Context: Before March 6th, which was the day I took Psylocybin, one of the psychedelics, I felt something was wrong in my world, but I couldn't label it in any way so as to get hold of it. I felt that the theories I was teaching in psychology didn't make it, that the psychologists didn't really have a grasp of the human condition, and that the theories I was teaching, which were theories of achievement and anxiety and defense mechanisms and so on, weren't getting to the crux of the matter.
My colleagues and I were 9 to 5 psychologists: we came to work every day and we did our psychology, just like you would do insurance or auto mechanics, and then at 5 we went home and were just as neurotic as we were before we went to work. Somehow, it seemed to me, if all of this theory were right, it should play more intimately into my own life. I understood the requirement of being "objective" for a scientist, but this is a most naive concept in social sciences as we are finding out....
Something was wrong. And the something wrong was that I just didn't know, though I kept feeling all along the way that somebody else must know even though I didn't. The nature of life was a mystery to me. All the stuff I was teaching was just like little molecular bits of stuff but they didn't add up to a feeling anything like wisdom. I was just getting more and more knowledgeable.

Si hubiera estado presente en la Creación, habría dado algunas indicaciones útiles.
After studying Ptolemy's treatise on astronomy.; reported in Thomas Carlyle, History of Frederick the Great, book ii. chap. vii. Carlyle wrote that this saying of Alfonso about Ptolemy's astronomy, "that it seemed a crank machine; that it was pity the Creator had not taken advice," is still remembered by mankind, — this and no other of his many sayings.
If the Lord Almighty had consulted me before embarking on creation thus, I should have recommended something simpler.

Context: The rejection process is incorporated in the concept of the negative. The negative is a judgement device. It is the means whereby one rejects certain arrangements of information. The negative is used to carry out judgement and to indicate rejection. The concept of the negative is crystallized into a definite language tool. This language tool consists of the words no and not. Once one learns the function and use of these words one has learned how to use logical thinking. The whole concept of logical thinking is concentrated in the use of this language tool. Logic could be said to be the management of NO.
