(las huellas dejadas por unas chispas en el polvo de una placa aislante)
"Draw near, woman, and hear what I have to say. Turn your curiosity for once towards useful objects, and consider the advantages which nature gave you and society ravished away. Come and learn how you were born the companion of man and became his slave; how you grew to like the condition and think it natural; and finally how the long habituation of slavery so degraded you that you preferred its sapping but convenient vices to the more difficult virtues of freedom and repute. If the picture I shall paint leaves you in command of yourselves, if you can contemplate it without emotion, then go back to your futile pastimes; ‘there is no remedy; the vices have become the custom.’"
Choderlos de Laclos, On the education of women, 1783
