A word to teachers

• He will have to learn, I know, that all men are not just and are not true. But teach him if you can, the wonder of books.. but also give him quiet time to ponder the eternal mystery of birds in the sky, bees in the sun and flowers on a green hillside.
• In school, teach him it is far more honorable to fall than to cheat.....
• Teach to have faith in his own ideas, even if everyone tells him he is wrong.
• Teach him to be gentle with gentlepeople and tough with the tough.
• Try to give my son the strength not to follow the crowd when everyone getting on the bandwagon...
• Teach him to listen to all men; but teach him also to filter all he hears on a screen of truth, and take only the good that comes through.
• Teach him, if you can, how to laugh when he is sad... Teach him there is no shame in tears.
• Teach him to scoff at cynics and to be beware of too much sweetness.. Teach him to sell his brawn and brain to highest bidders, but never to put a price on his heart and soul. Teach him to close his ears to a howling mob.. and stand and fight if thinks he is right.
• Treat him gently, but do not cuddle him, because only the test of fire makes fine steel. Let him have the courage to be impatient.. Let him have the patience to be brave. Teach him always to have sublime faith in himself, because then he will have faith in humankind.
• This is a big order, but see what you can do. . He is such a fine little fellow my son!

Richard Feynman

• I think it is more interesting to live not knowing answers than to have answers that might be wrong, I have approximate answers, possible beliefs, and different degrees of certainty about different things, but I'm not absolutely certain of anything, and there's some things I know nothing about at all - like whether it means anything to ask, 'Why are we here?' I might think about it for a little while, but if I can't figure it out then I'll go on to something else. I'm not afraid of being lost in a mysterious universe with no purpose, which is the way it is, possibly. It doesn't frighten me.
