" Why do you consult [women's] words when it is not their mouths that speak? Consult their eyes, their colour, their breathing, their timid manner, their slight resistance, that is the language nature gave them for your answer. The lips always say 'No,' and rightly so; but the tone is not always the same, and that cannot lie. Has not a woman the same needs as a man, but without the same right to make them known? Her fate would be too cruel if she had no language in which to express her legitimate desires except the words which she dare not utter. "

― Jean-Jacques Rousseau , Emile, or On Education
