Mancando le qualità morali di misura precisa, se anche ci fosse l'accordo sul segno, come ci potrebbe essere sulla valutazione? - Jean-Jacques Rousseau

Di solito si ottiene con tutta sicurezza e assai presto ciò che non si ha fretta di ottenere.

Why should we build our happiness on the opinons of others, when we can find it in our own hearts?

To select these objects, to take care to present him constantly with those he may know, to conceal from him those he ought not to know, this is the real way of training his early memory; and in this way you must try to provide him with a storehouse of knowledge which will serve for his education in youth and his conduct throughout life. True, this method does not produce infant prodigies, nor will it reflect glory upon their tutors and governesses, but it produces men, strong, right-thinking men, vigorous both in mind and body, men who do not win admiration as children, but honour as men.
