I fear explanations explanatory of things explained.
Those who write clearly have readers; those who write obscurely have commentators.
Not failure, but low aim, is crime.
In great attempts it is glorious even to fail.
Aim at the sun, and you may not reach it; but your arrow will fly far higher than if aimed at an object on a level with yourself.
You can easily play a joke on a person who likes to argue: agree with him.
The fellow who agrees with everything you say is either a fool or he is getting ready to skin you.
If you wish to appear agreeable in society, you must consent to be taught many things which you know already.
I have never in my life learned anything from anyone who agreed with me.
There is no conversation more boring than one where everybody agrees.
