The good man is the teacher of the bad, And the bad is the material from which the good may learn. He who does not value the teacher, Or greatly care for the material, Is greatly deluded although he may be learned. Such is the essential mystery.
It goes against the grain of modern education to teach children to program. What fun is there in making plans, acquiring discipline in organizing thoughts, devoting attention to detail and learning to be self-critical?
Thinking and spoken discourse are the same thing, except that what we call thinking is, precisely, the inward dialogue carried on by the mind with itself without spoken sound.
I praise God for you, sir: your reasons at dinner have been sharp and sententious; pleasant without scurrility, witty without affectation, audacious without impudency, learned without opinion, and strange with-out heresy.
A young man is not a proper hearer of lectures on political science; for he is inexperienced in the actions that occur in life, but its discussions start from these and are about these; and, further, since he tends to follow his passions, his study will be vain and unprofitable, because the end that is aimed at is not knowledge but action. And it makes no difference whether he is young in years or youthful in character.
I wonder what especial sanctity attaches itself to fifteen minutes. It is always the maximum and the minimum of time which will enable us to acquire languages, etiquette, personality, oratory ... One gathers that twelve minutes a day would be hopelessly inadequate, and twenty minutes a wasteful and ridiculous excess.
The bookful blockhead ignorantly read, With loads of learned lumber in his head, With his own tongue still edifies his ears, And always list'ning to himself appears. All books he reads, and all he reads assails.
What I must do is all that concerns me, not what people think. This rule,equally arduous in actual and intellectual life, may serve for the whole distinction between greatness and meanness. It is the harder, because you will always find those who think they know what is your duty better than you know it. It is easy in the world to live after the world's opinion; it is easy in solitude to live after our own; but the great man is he who in the midst of the crowd keeps with perfect sweetness the independence of solitude.
The greater the scientist, the more he is impressed with his ignorance of reality, and the more he realizes that his laws and labels, descriptions and definitions, are the products of his own thought. They help him to use the world for purposes of his own devising rather than understand and explain it.
