It is good to rub and polish our brains against that of others.
Michel de Montaigne
We think too small. Like the frog at the bottom of the well. He thinks the sky is only as big as the top of the well. If he surfaced, he would have an entirely different view.
Where all think alike, no one thinks very much.
Thoughts are but dreams till their effects be tried.
Words without thoughts never to heaven go.
Men give me some credit for genius. All the genius I have lies in this: When I have a subject in hand, I study it profoundly. Day and night it is before me. I explore it in all its bearings. My mind becomes pervaded with it. Then the effort which I make is what the people call the fruit of genius. It is the fruit of labor and thought.
The aim of education should be to teach us how to think, rather than what to think.
What gems of painting or statuary are in the world of art, or what flowers are in the world of nature, are gems of thought to the cultivated and the thinking.
Oliver Wendell Holmes
We bring forth weeds when our quick minds lie still.
All truly wise thoughts have been thought already, thousands of times; but to make them truly ours, we must think them over again honestly, till they take firm root in our personal experience.
Johann Wolfgang von Goethe
The less men think, the more they talk.
Learning without thought is labor lost; thought without learning is perilous.
The universe is change;
our life is what our thoughts make it.
But words are things, and a small drop of ink
Falling like dew upon a thought, produces
That which makes thousands, perhaps millions, think.
Sir Aubrey De Vere
Thoughts rule the world.
Ralph Waldo Emerson
Thinking is the hardest work there is, which is the probably reason why so few people engage in it.
The efficient man is the man who thinks for himself, and is capable of thinking hard and long.
Charles W. Eliot
They are never alone that are accompanied with noble thoughts.
Sir Philip Sidney
Change your thoughts and you change your world.
Norman Vincent Peale
Obvious thinking commonly leads to wrong judgments and wrong conclusions.
Humphrey B. Neil
Language is the close-fitting dress of thought.
R. C. Trench
