There is no reason why an extraphysical general principle is necessarily to be avoided, since such principles could conceivably serve as useful working hypotheses. For the history of scientific research is full of examples in which it was very fruitful indeed to assume that certain objects or elements might be real, long before any procedures were known which would permit them to be observed directly.
David BohmWe have reversed the usual classical notion that the independent "elementary parts" of the world are the fundamental reality, and that the various systems are merely particular contingent forms and arrangements of these parts. Rather, we say that inseparable quantum interconnectedness of the whole universe is the fundamental reality, and that relatively independent behaving parts are merely particular and contingent forms within this whole.
David BohmIndeed, the attempt to live according to the notion that the fragments are really separate is, in essence, what has led to the growing series of extremely urgent crises that is confronting us today.
David BohmWe have the idea that after we have been thinking something, it just evaporates. But thinking doesn't disappear. It goes somehow into the brain and leaves something-a trace-which becomes thought. And thought then acts automatically.
David BohmWhen you are thinking something, you have the feeling that the thoughts do nothing except inform you the way things are and then you choose to do something and you do it. That's what people generally assume. But actually, the way you think determines the way you're going to do things. Then you don't notice a result comes back, or you don't see it as a result of what you've done, or even less do you see it as a result of how you were thinking. Is that clear?
