Penguin Island Book I by Anatole France

Jealousy is a virtue of democracies which preserves them from tyrants. Deputies began to envy the Prime Minister his golden key. For a year his domination over the beauteous Madame Cérès had been known to the whole universe. The provinces, whither news and fashions only arrive after a complete revolution of the earth round the sun, were at last informed of the illegitimate loves of the Cabinet. The provinces preserve an austere morality; women are more virtuous there than they are in the capital.

Various reasons have been alleged for this: Education, example, simplicity of life. Professor Haddock asserts that this virtue of provincial ladies is solely due to the fact that the heels of their shoes are low. "A woman," said he, in a learned article in the "Anthropological Review", "a woman attracts a civilized man in proportion as her feet make an angle with the ground. If this angle is as much as thirty-five degrees, the attraction becomes acute. For the position of the feet upon the ground determines the whole carriage of the body, and it results that provincial women, since they wear low heels, are not very attractive, and preserve their virtue with ease." These conclusions were not generally accepted.
