Note 84 — Chapter VI

I interpret this: “There are fewer vibrations persistent within the bodies of the lower animals; those that there are, therefore, are stronger and more capable of generating action or upsetting the status in quo. Hence also they require less accession of vibration from without. Man is agitated by more and more varied vibrations; these, interfering, as to some extent they must, with one another, are weaker, and therefore require more accession from without before they can set the mechanical adjustments of the body in motion.”
