Short idea (122): Computers have been compared to brains and spoken of as brains, but the brain has different parts. It seems to me that computers can be correctly compared with the higher cortical brain, the part considered to be responsible for logical thinking, the type of thinking used to solve complex mathematical problems. But computers do not have lower brains, the part of the brain connected with need and want and drive and emotion and passion. Because of this, computers can't be irrational; they can generate random series of numbers, and they can make mistakes, but this is different from being irrational. To be irrational you have to have interests, and you have to have passions that make you act irrationally by going against your interests. Computers don't have interests, so they can't act irrationally. If a computer could be given a lower brain, such a computer would be much more human.
Short idea (152): An introspective exercise I did made me think that thinking is a branch of the imagination and that reason is a branch of thinking. However, it is just as possible that thinking and fantasy are offspring of the same parent (maybe the need to grasp the future). Or that they both come from the same root or need. Or that they are two forms of the same thing.

A Paradox: The gods are real and they are not real
If Freud and others are right, it is as if we have two minds, that is two ways of thinking. Typically, one is active at night when we are asleep, while the other is dominant during the day when we are awake and alert. The two ways of thinking are as different as night and day. The purest example of the night-time mind would be a dream, and the purest example of day-time thinking would be a rational, logical, scientific chain of thought. In sleep we relax away from the strict rules of rational thought and reality testing only to shoulder them again when we begin to awaken. Being rational and logical requires work, whereas, in the night-time mind, whatever is is real, and no evaluating is required. It is possible for the night-time mind to emerge and even take over in the day, and it is also possible for a person to think logically within a dream. For most people this may happen sometimes, and for some it may happen quite often. For some people, the rational, reality testing mind may be all but absent, even in the day, and waking consciousness then takes on a dream-like feeling where impressions and intuitions and feelings and inclinations rule without challenge and without control.
