Note 127 — AN ESSAY ON CRITICISM.

"Everybody allows," says Malebranche, "that the animal spirits are the most subtle and agitated parts of the blood. These spirits are carried with the rest of the blood to the brain, and are there separated by some organ destined to the purpose." Pope adopted the doctrine "allowed by everybody," but which consisted of assumptions without proof. The very existence of these fluid spirits had never been ascertained. The remaining physiology of Pope's couplet was erroneous. When there is a deficiency of blood, its place is not supplied by wind. The grammatical construction, again, is vicious, and ascribes "blood and spirits" to souls as well as to bodies. The moral reflection illustrated by the simile is but little more correct. Men in general are not proud in proportion as they have nothing to be proud of.
