 of ephemeral insects that succeeded one another without transmitting experience might repeat the same round of impressions—an everlasting progression without a shadow of progress. Such, too, is the idiot’s life: his liquid brain transmits every impulse without resistance and retains the record of no impression.

Intelligence is accordingly conditioned by a modification of both structure and consciousness by dint of past events. To be aware that a second stroke is not itself the first, I must retain something of the old sensation. The first must reverberate still in my ears when the second arrives, so that this second, coming into a consciousness still filled by the first, is a different experience from the first, which fell into a mind perfectly empty and unprepared. Now the newcomer finds in the subsisting One a sponsor to christen it by the name of Two. The first stroke was a simple 1. The second is not simply another 1, a mere iteration of the first. It is 11, where the coefficient represents the reverberating first stroke, still persisting in the mind, and forming a background and perspective against which the new stroke may be distinguished. The meaning of “two,” then, is “this after that” or “this again,” where we have a simultaneous sense of two things which have been separately perceived but are identified as similar in their nature. Repetition must cease to be pure repetition and become cumulative before it can give rise to the consciousness of repetition.
