فيا أيها الإنسان كُنْ من أي بلدٍ شئت، ولتكن آراؤك كما أردت، واستمع، فهذا هو تاريخك كما أرى قراءته، لا في كتب أمثالك الذين هم كاذبون، بل في الطبيعة التي … - Jean-Jacques Rousseau

History tells us, that from the moment when the moral forces on which a civilisation rested have lost their strength, its final dissolution is brought about by those unconscious and brutal crowds known, justifiably enough, as barbarians.

El gusto por la soledad y la contemplación nació en mi corazón con los sentimientos expansivos y tiernos hechos para ser su alimento. El tumulto y el ruido los oprimen y los ahogan, la calma y la paz los reaniman y los exaltan. Tengo necesidad de recogerme para amar.

Teach your scholar to observe the phenomena of nature; you will soon rouse his curiosity, but if you would have it grow, do not be in too great a hurry to satisfy this curiosity. Put the problems before him and let him solve them himself. Let him know nothing because you have told him, but because he has learnt it for himself. Let him not be taught science, let him discover it. If ever you substitute authority for reason he will cease to reason; he will be a mere plaything of other people's thoughts.
