Thought reflexes get conditioned very strongly, and they are very hard to change. And the also interfere. A reflex may connect to the endorphins and produce an impulse to hold that whole pattern forther. In other words, it produces a defensive reflex. Not merely is it stuck because it's chemically so well built up, but also there is a defensive reflex which defends against evidence which might weaken it. Thus it all happens, one reflex after another after another. It's just a vast system of reflexes. And they form a 'structure' as they get more rigid.
David BohmThis is another major feature of thought: Thought doesn't know it is doing something and then it struggles against it is doing. It doesn't want to know that it is doing it.
David BohmFrom the point of view of the species, death is part of this whole process. You could say that species have evolved in such a way that individual members last a certain time. Perhaps a certain kind of species would be better able to survive if the individuals didn't last too long. Other kinds could last longer.
David BohmAnd thought struggles against the results, trying to avoid those unpleasant results while keeping on with that way of thinking. That is what I call 'sustained incoherence.
David BohmIn nature nothing remains constant. Everything is in a perpetual state of transformation, motion, and change. However, we discover that nothing simply surges up out of nothing without having antecedents that existed before. Likewise, nothing ever disappears without a trace, in the sense that it gives rise to absolutely nothing existing in later times.
David BohmThe treatment of the indeterminacy principle as absolute and final can then be criticized as constituting an arbitrary restriction on scientific theories, since it does not follow from the quantum theory as such, but rather from the assumption of the unlimited validity of certain of its features, an assumption that can in no way ever be subjected to experimental proof.
