Dad dinero, y pronto tendréis cadenas - Jean-Jacques Rousseau

Mais le corps politique ou le souverain ne tirant son être que de la sainteté du contrat ne peut jamais s'obliger, même envers autrui, à rien qui déroge à cet acte primitif, comme d'aliéner quelque portion de lui-même ou de se soumettre à un autre souverain. Violer l'acte par lequel il existe serait s'anéantir, et ce qui n'est rien ne produit rien.

So here I am, all alone on this earth, with no brother, neighbour, or friend, and no company but my own. The most sociable and loving of human beings has by common consent been banished by the rest of society. In the refinement of their hatred they have continued to seek the cruellest forms of torture for my sensitive soul, and they have brutally severed all the ties which bound me to them. I would have loved my fellow men in spite of themselves. Only by ceasing to be men have they succeeded in losing my affection for them. So now they are strangers, persons unknown who mean nothing to me since that is what they wanted. But what about me, cut off from them and from everything else, what am I? This is what remains for me to find out now.

Complete ignorance with regard to certain matters is perhaps the best thing for children; but let them learn very early what it is impossible to conceal from them permanently. Either their curiosity must never be aroused, or it must be satisfied before the age when it becomes a source of danger. Your conduct towards your pupil in this respect depends greatly on his individual circumstances, the society in which he moves, the position in which he may find himself, etc. Nothing must be left to chance; and if you are not sure of keeping him in ignorance of the difference between the sexes till he is sixteen, take care you teach him before he is ten.
