Formidable machines indeed…

The glances of women are like certain apparently peaceful, but really formidable, machines. You pass them every day quietly, with impunity, and without suspicion of danger. There comes a moment when you forget even that they are there. You come and go, you muse and talk and laugh. Suddenly you feel that you are seized; it is done. The wheels have caught you, the glance has captured you. It has taken you, no matter how or where, by any portion whatever of your thought which was trailing. Through any absence of mind, you are lost. You will be drawn in entirely. A chain of mysterious forces has gained possession of you. You struggle in vain; no human succor is possible. You will be drawn down, from wheel to wheel, from anguish to anguish, from torture to torture. You, your mind, your fortune, your future, your soul; and, you will not escape from the terrible machine until, according as you are in the power of a malevolent nature, or a noble heart, you will be disfigured by shame, or transfigured by love.
