La legge della necessità, sempre rinascente, insegna presto all'uomo a far ciò che non gli piace, per prevenire un male che gli dispiacerebbe di più.
—  Jean-Jacques Rousseau

Hold childhood in reverence, and do not be in any hurry to judge it for good or ill. … You assert that you know the value of time and are afraid to waste it. You fail to perceive that it is a greater waste of time to use it ill than to do nothing, and that a child ill taught is further from virtue than a child who has learnt nothing at all. You are afraid to see him spending his early years doing nothing. What! is it nothing to be happy, nothing to run and jump all day?

–Jean-Jacques Rousseau, Emile, or On Education
