Excerpt from The Pedagogical Seminary, Vol. 6: An International Record of Educational Literature, Institutions and Progress Jackson's theory is thoroughly evolutionary in its essential conceptions. What are the lowest levels, says Jackson, are centers for the simplest movements of the limbs, which become evolved, in the highest centers, into the physical basis of volition. What in the lowest levels are centers for simple reflex action of the eyes and hands are evolved in the highest level, with the physical basis of tactual ideas. What are the lowest centers for movements of the tongue, palate, lips, etc., as employed in eating, swallowing, etc are, in the highest centers, evolved into the physical basis of words, as symbols serving abstract reasoning, what are the lowest centers for cir culatory, respiratory and digestive movements, in the highest centers, are the physical basis of the emotions. So to speak, the lowest level does menial work; the highest level, evolved out of. It, becomes in great degree independent of it and is the anatomical basis of mind.
