“Seth material” search engine (Jane Roberts)

Dictation. (Pause.) If there were no idiots among you, you would soon find that geniuses were absent also.

Those human abilities that you consider to be characteristic of your species are, again, dependent upon the existence of infinite numbers of variations that appear in the aggregate, to give you often obviously opposing states. What you think of then as the average intelligence is a condition that exists because of the activity of constant variables, minute variations that give you at one end of the scale the idiot, and at the other the genius.

(9:45.) In no way do I mean to demean the indisputable value of geniuses, or their great contributions to the quality of life—but the quality of life is, again, also benefited by the existence of idiots. Not only because both ends of the scale are necessary for genetic reasons, but also because idiots themselves are in no way considered failures or defects by nature. Those terms are human judgments. Idiots also serve their role by moderating the sometimes fierce hold that the reasoning mind can (underlined) have upon human activity.
