A husband should sleep as lightly as a watch-dog, so as never to be caught with his eyes shut. A man should accustom himself from childhood to go to bed bareheaded. Certain poets discern in modesty, in the alleged mysteries of love, some reason why the married couple should share the same bed; but the fact must be recognized that if primitive men sought the shade of caverns, the mossy couch of deep ravines, the flinty roof of grottoes to protect his pleasure, it was because the delight of love left him without defence against his enemies. No, it is not more natural to lay two heads upon the same pillow, than it is reasonable to tie a strip of muslin round the neck. Civilization is come. It has shut up a million of men within an area of four square leagues; it has stalled them in streets, houses, apartments, rooms, and chambers eight feet square; after a time it will make them shut up one upon another like the tubes of a telescope. From this cause and from many others, such as thrift, fear, and ill-concealed jealousy, has sprung the custom of the sleeping together of the married couple; and this custom has given rise to punctuality and simultaneity in rising and retiring. And here you find the most capricious thing in the world, the feeling most pre-eminently fickle, the thing which is worthless without its own spontaneous inspiration, which takes all its charm from the suddenness of its desires, which owes its attractions to the genuineness of its outbursts--this thing we call love, subjugated to a monastic rule, to that law of geometry which belongs to the Board of Longitude! If I were a father I should hate the child, who, punctual as the clock, had every morning and evening an explosion of tenderness and wished me good-day and good-evening, because he was ordered to do so. It is in this way that all that is generous and spontaneous in human sentiment becomes strangled at its birth. You may judge from this what love means when it is bound to a fixed hour! Only the Author of everything can make the sun rise and set, morn and eve, with a pomp invariably brilliant and always new, and no one here below, if we may be permitted to use the hyperbole of Jean-Baptiste Rousseau, can play the role of the sun. From these preliminary observations, we conclude that it is not natural for two to lie under the canopy in the same bed; That a man is almost always ridiculous when he is asleep; And that this constant living together threatens the husband with inevitable dangers. We are going to try, therefore, to find out a method which will bring our customs in harmony with the laws of nature, and to combine custom and nature in a way that will enable a husband to find in the mahogany of his bed a useful ally, and an aid in defending himself. 1.
