"It is certain that nature inclines us toward the amorous orgy, just as much as toward the gastronomic orgy, and that while both are blameworthy in the excess, they would become praiseworthy in an order in which they could be equilibrated."

“There is no idea more novel, more surprising, than that of associating three hundred families of different degrees of fortune, knowledge and capacity.”

“Nowhere is there more constancy and more unanimity than among the French to subordinate that sex which they pretend to honor so highly.”

“If children are a joy for the well-to-do, they are a torment for seven-eights of all civlizees, who cannot afford to maintain and educate them.”

“When we see civilization elated with this declining and decrepit phase of its career, we are reminded of a faded belle who, boasting of her attractions in her fiftieth year, excites at once the remark that she was fairer at twenty-five.

“The seeds of heavenly bodies are deposited and cared for in the Milky Way, from which they emanate in swarms of comets that travel a ;long time and ordinarily gravitate towards various suns before becoming fixed in orbit.”

“You complain that the nature withholds from you a knowledge of her laws; but if you have been unable, to to present time, to discover them, why do you hesitate to admit the insufficiency of your methods and to invoke a new science, a new guide? Either nature does not desire the happiness of man, or your methods are condemned by her, since they have been unable to west from her the secret of which you are in pursuit. Do we find her frustrating the efforts of the natural philosophers as she does yours? no, because they study her laws instead of dictating laws to her; while you only study the art of stifling the voice of nature stifling attraction which is her interpreter, and the synthesis of which leads in every sense to association. What a contrast between your blunders and the achievements of the positive sciences! Every day, philosophers, you add new errors to the errors of the past, whereas we see the physical sciences daily advancing in the path of truth, and shedding as much luster upon the present century as your baseless vision have cast opprobrium upon the eighteenth.”
