"There's no reason why women shouldn't behave like rational beings," Simon asserted stolidly.

Those who do not believe that a woman can make a man happy through the twenty-four hours of the day have never possessed a woman like Henriette. The happiness which filled me, if I can express it in that manner, was much greater when I conversed with her even than when I held her in my arms. She had read much, she had great tact, and her taste was naturally excellent; her judgment was sane, and, without being learned, she could argue like a mathematician, easily and without pretension, and in everything she had that natural grace which is so charming. She never tried to be witty when she said something of importance, but accompanied her words with a smile which imparted to them an appearance of trifling, and brought them within the understanding of all. In that way she would give intelligence even to those who had none, and she won every heart. Beauty without wit offers love nothing but the material enjoyment of its physical charms, whilst witty ugliness captivates by the charms of the mind, and at last fulfils all the desires of the man it has captivated.
