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.

I hate books; they only teach us to talk about things we know nothing about.

My bad head cannot adjust itself to the way things are....

The man is best served who has no occasion to put the hands of others at the end of his own arms.
