“I one day asked M. Nicole what was the character of Mme. de Longueville’s intellect; he told me it was very subtle and delicate in the penetration of character; but very small, very feeble, and that her comprehension was extremely narrow in matters of science and reasoning, and on all speculations that did not concern matters of sentiment. For example, he added, I one day said to her that I could wager and demonstrate that there were in Paris at least two inhabitants who had the same number of hairs, although I could not point out who these two men were. She told me I could never be sure of it until I had counted the hairs of these two men. Here is my demonstration, I said: I take it for granted that the head which is most amply supplied with hairs has not more than 200,000, and the head which is least so has but one hair. Now, if you suppose that 200,000 heads have each a different number of hairs, it necessarily follows that they have each one of the numbers of hairs which form the series from one to 200,000; for if it were supposed that there were two among these 200,000 who had the same number of hairs, I should have gained my wager. Supposing, then, that these 200,000 inhabitants have all a different number of hairs, if I add a single inhabitant who has hairs, and who has not more than 200,000, it necessarily follows that this number of hairs, whatever it may be, will be contained in the series from one to 200,000, and consequently will be equal to the number of hairs on one of the previous 200,000 inhabitants. Now as, instead of one inhabitant more than 200,000, there are nearly 800,000 inhabitants in Paris, you see clearly that there must be many heads which have an equal number of hairs, though I have not counted them. Still Mme. de Longueville could never comprehend that this equality of hairs could be demonstrated, and always maintained that the only way of proving it was to count them.” Surely, the most ardent admirer of feminine shallowness must have felt some irritation when he found himself arrested by this dead wall of stupidity, and have turned with relief to the larger intelligence of Madame de Sablé, who was not the less graceful, delicate, and feminine because she could follow a train of reasoning, or interest herself in a question of science. In this combination consisted her pre-eminent charm: she was not a genius, not a heroine, but a woman whom men could more than love—whom they could make their friend, confidante, and counsellor; the sharer, not of their joys and sorrows only, but of their ideas and aims.
