The indifference of children towards meat is one proof that the taste for meat is unnatural; their preference is for vegetable foods...Beware of changing this natural taste and making children flesh-eaters, if not for their health's sake, for the sake of their character; for how can one explain away the fact that great meat-eaters are usually fiercer and more cruel than other men; this has been recognised at all times and in all places.
Jean-Jacques RousseauTeach 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.
Jean-Jacques RousseauBut in some great souls, who consider themselves as citizens of the world, and forcing the imaginary barriers that separate people from people.
