Physical Prejudices

The sun rises, the moon also, the earth is motionless: these are natural physical prejudices. But that lobsters are good for the blood, because when cooked they are red; that eels cure paralysis because they wriggle; that the moon affects our maladies because one day someone observed that a sick man had an increase of fever during the waning of the moon; these ideas and a thousand others are the errors of ancient charlatans who judged without reasoning, and who, being deceived, deceived others.
