“Seth material” search engine (Jane Roberts)

More complicated organisms — mammals, for example — have need of further mechanisms to construct ideas because they are able to perceive more of them. Here memory is an element. Now the organism has a built-in ghost image of past constructions by which to perfect and test new ones. Reflection of some sort enters into the picture, and with it the organism is given more to do. Slowly, within its range of receptivity, it is given some choice in the actual construction of ideas into physical reality.

Entities with still broader range need more complicated structure. The scope of their receptivity is so large that the simple autonomic nervous system is not enough. The amoeba constructs each idea it receives, because it is able to receive so few. All must be constructed to ensure survival. With man, the opposite becomes true. He has such a range of receptivity that it is impossible for him to construct all of his ideas physically. As his scope widened, a mechanism was necessary that would allow him to choose. Self-consciousness and reason were the answers.
