“Seth material” search engine (Jane Roberts)

In man, the probabilities of development are literally numberless. No computer could count the combinations of characteristics possible. It is highly important, then, that the species retain flexibility, and not become locked into any one pattern, however advantageous (intently)—and I am referring to physical or mental patterns. Within the framework of established specieshood, there must be every kind of leeway—leeways that are biologically activated, so that variances are constantly active. Those genetic variances may appear as defective or eccentric. They may appear as the handicapped. They may appear as superior characteristics of one kind or another, but they must be biologically stated as the variations from the genetic norm.

Here in Dreams Seth uses the uncertainty principle as an analogy (and an excellent one), meaning that as the positions and motions of elementary particles, say, cannot be simultaneously measured precisely, so our genetic qualities and their motions can not always be specifically determined. In Dreams he’s already said (in Session 909) that the human species has an “amazing interplay between genetic preciseness and genetic freedom,” and (in Session 910) that “your genetic structure reacts to each thought that you have, to the state of your emotions, to your psychological climate.” Choices and probabilities apply. Thus do we avoid genetic rigidity.
