Psychology (Briefer Course)

No doubt it is often convenient to formulate the mental facts in an atomistic sort of way, and to treat the higher states of consciousness as if they were all built out of unchanging simple ideas which ‘pass and turn again.’ It is convenient often to treat curves as if they were composed of small straight lines, and electricity and nerve-force as if they were fluids. But in the one case as in the other we must never forget that we are talking symbolically, and that there is nothing in nature to answer to our words. A permanently existing ‘Idea’ which makes its appearance before the footlights of consciousness at periodical intervals is as mythological an entity as the Jack of Spades. Within each personal consciousness, thought is sensibly continuous. I can only define ‘continuous’ as that which is without breach, crack, or division.
