Mme. de Lambert taught her children to be satisfied with nothing but the highest attainable object. She advised her son to choose his friends from among men above him, in order to accustom himself to respectful and polite demeanor; "with his equals he might cultivate negligence and his mind might become dull." She desired her children to think differently from the people—"Those who think lowly and commonly, and the court is filled with such." To their servants they were to be good and kind, for humanity and Christianity make all equal. She was the first to use those words, "humanity" and "equality," which later became the bywords of everyone, and the first to teach that conscience is the best guide. "Conscience is defined as that interior sentiment of a delicate honor which assures you that you have nothing with which to reproach yourself."
Possibly the most important and lasting effect of Mme. de Lambert's influence resulted from the expression of her ideas on the education of young women who "are destined to please, and are given lessons only in methods of delighting and pleasing." She was convinced that in order to resist temptation and be normal, women must be educated, must learn to think. Her counsels to her daughter are remarkable for an unusual insight into the temperament of her sex and for an extreme fear that makes her call to her aid all precautions and resources. She thus advises her daughter:
"Try to find resources within yourself—this is a revenue of certain pleasures. Do not believe that your only virtue is modesty; there are many women who know no other virtue, and who imagine that it relieves them of all duties toward society; they believe they are right in lacking all others and think themselves privileged to be proud and slanderous with impunity. You must have a gentle modesty; a good woman may have the advantages of a man's friendship without abandoning honesty and faithfulness to her duties. Nothing is so difficult as to please without the use of what seems like coquettishness. It is more often by their defects than by their good qualities that women please men; men seek to profit by the weaknesses of good and kind women, for whose virtues they care nothing, and they prefer to be amused by persons not very estimable than to be forced merely to admire virtuous persons."
This is a most faithful description of the society of her time, and it was because her treatises struck home that they were severely criticised; but, nothing daunted, she carried out her plans in her own way, resorting neither to intrigue nor artifice. Many of her sayings became household maxims, such as—"It is not always faults that undo us; it is the manner of conducting ourselves after having committed them."
Her reflections on women might be called the great plea, at the end of the seventeenth century, for woman's right to use her reason. After the severe and cruel satire of Molière, attacking women for their innocent amusements, they gave themselves up entirely to pleasure. "Mme. de Lambert now wrote to avenge her sex and demand for it the honest and strong use of the mind; and this was done in the midst of the wild orgies of the Regency."
Mme. de Lambert was not a rare beauty, but she possessed recompensing charms. M. Colombey asserts that she became convinced of two things, about which she became highly enthusiastic: first, that woman was more reasonable than man; secondly, that M. Fontenelle, who presided over or filled the functions of president of her salon, was always in the right. He was indeed in harmony with the tone of the salon, being considered the most polished, brilliant, and distinguished member of the intellectual society of Paris, as well as one of the most talented drawing room philosophers. He made the salon of Mme. de Lambert the most sought for and celebrated, the most intellectual and moral of the period.
Mme. de Lambert has, possibly, exercised more influence upon men—and especially upon the Forty Immortals of her time—than did any woman before or after her. The Marquis d'Argenson states that "a person was seldom received at the Academy unless first presented at her salon. It is certain that she made at least half of our actual Academicians."
Her salon was called a bureau d'esprit, which was due to the fact that it was about the only social gathering point where culture and morality were the primary requisites. As she advanced in years, she became even more influential. After her death in 1733, her salon ceased to exist, but others, patterned after hers, soon sprang up; to those, her friends attached themselves—Fontenelle frequented several, Hénault became the leader of that of Mme. du Deffand.
The finest résumé that can be given of Mme. de Lambert, is found in the letters of the Marquis d'Argenson: "Her works contain a complete course in the most perfect morals for the use of the world and the present time. Some affectation of the préciosité is found; but, what beautiful thoughts, what delicate sentiments! How well she speaks of the duties of women, of friendship, of old age, of the difference between actual character and reputation!"
