me repetía este proverbio provinciano, algo menos exacto en París, que el que bien canta y bien danza trabaja mucho y no avanza. - Jean-Jacques Rousseau

Doubt with regard to what we ought to know is a condition too violent for the human mind; it cannot long be endured; in spite of itself the mind decides one way or another, and it prefers to be deceived rather than to believe nothing.

With regard to equality, this word must not be understood to mean that degress of power and wealth should be exactly the same, but rather that with regard to power, it should be incapable of all violence and never exerted except by virtue of status and the laws; and with regard to wealth, no citizen should be so opulent that he can buy another, and none so poor that he is constrained to sell himself.

¿Cómo se han de querer? Sólo en sí mismo piensa cada uno.
