Note 7 — Chapter IX

In order not to permit an apparent contradiction of the above-mentioned speculation to the psychophysical doctrine of the combined-threshold (upon which the most enlightening word is in Wundt’s philos. Stud., IV, s. 204 u. 211), note the following: If the psychophysical life-wave (to continue the use of this concise expression) of man, made up of components of the most manifold sort, should spread out into a world which contained only different components, then, indeed, must it be assumed that it, in its extension, would fall below the combined-threshold here under consideration. Since, however, the psychophysical undulatory sea of the universe, among its other components, comprehends also such as are like to those of the human life-wave, and indeed of the most varying height or intensity, therefore such as already rise above or come near the level of the combined-threshold and are only raised still higher by the similar ones which join them, so is the result of the above speculation placed on a somewhat more solid basis.
