It is good to rub and polish our brain against that of others.

.. since it was true that study, even when done properly, can only teach us what wisdom, right conduct and determination consist in, they wanted to put their children directly in touch with actual cases, teaching them not by hearsay but by actively assaying them, vigorously molding and forming them not merely by word and precept but chiefly by deeds and examples, so that wisdom should not be something which the soul knows but the soul's very essence and temperament, not something acquired but a natural property.

Fear sometimes adds wings to the heels, and sometimes nails them to the ground, and fetters them from moving.

In truth, knowledge is a great and very useful quality; those who despise it give evidence enough of their stupidity. Yet I do not set its value at that extreme measure that some attribute to it.
