I think with the Romans, that the general of today should be a soldier tomorrow if necessary.

Thomas Jefferson

Never think there is anything impossible for the soul. It is the greatest heresy to think so. If there is sin, this is the only sin; to say that you are weak, or others are weak.

Swami Vivekananda

We are very much what others think of us. The reception our observations meet with gives us courage to proceed, or damps our efforts.

William Hazlitt

I think, then, that man, after having satisfied his first longing for facts, wanted something fuller – some grouping, some adaptation to his capacity and experience, of the links of this vast chain of events which his sight could not take in.

Alfred de Vigny

They say that God is everywhere, and yet we always think of Him as somewhat of a recluse.

Emily Dickinson

If you think you can win, you can win. Faith is necessary to victory.

William Hazlitt

People think they have taken quite an extraordinarily bold step forward when they have rid themselves of belief in hereditary monarchy and swear by the democratic republic. In reality, however, the state is nothing but a machine for the oppression of one class by another, and indeed in the democratic republic no less than in the monarchy.

Friedrich Engels

Of all noises, I think music is the least disagreeable.

Samuel Johnson

To think is easy. To act is hard. But the hardest thing in the world is to act in accordance with your thinking.

Johann Wolfgang von Goethe

For Debussy the musician and the man I have had profound admiration, but by nature I’m different from him. I think I have always personally followed a direction opposed to that of the symbolism of Debussy.

Maurice Ravel

I do not think much of a man who is not wiser today than he was yesterday.

Abraham Lincoln

If you start to think of your physical and moral condition, you usually find that you are sick.

Johann Wolfgang von Goethe

The surest way to corrupt a youth is to instruct him to hold in higher esteem those who think alike than those who think differently.

Friedrich Nietzsche

If once a man indulges himself in murder, very soon he comes to think little of robbing; and from robbing he comes next to drinking and Sabbath-breaking, and from that to incivility and procrastination.

Thomas De Quincey

I care not what others think of what I do, but I care very much about what I think of what I do! That is character!

Theodore Roosevelt

As a single footstep will not make a path on the earth, so a single thought will not make a pathway in the mind. To make a deep physical path, we walk again and again. To make a deep mental path, we must think over and over the kind of thoughts we wish to dominate our lives.

Henry David Thoreau

I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success. Such emotions make a man forget food, sleep, friends, love, everything.

Nikola Tesla

I don't believe one grows older. I think that what happens early on in life is that at a certain age one stands still and stagnates.

George Eliot

We think in generalities, but we live in detail.

Alfred North Whitehead

Seeing so much poverty everywhere makes me think that God is not rich. He gives the appearance of it, but I suspect some financial difficulties.

Victor Hugo

They are ill discoverers that think there is no land, when they can see nothing but sea.

Francis Bacon

I think it’s very healthy to spend time alone. You need to know how to be alone and not be defined by another person.

Oscar Wilde

If you would be wealthy, think of saving as well as getting.

Benjamin Franklin

Metaphysics means nothing but an unusually obstinate effort to think clearly.

William James

Men are more moral than they think and far more immoral than they can imagine.

Sigmund Freud

Think of yourself as on the threshold of unparalleled success. A whole, clear, glorious life lies before you. Achieve! Achieve!

Andrew Carnegie

If we help an educated man’s daughter to go to Cambridge are we not forcing her to think not about education but about war? – not how she can learn, but how she can fight in order that she might win the same advantages as her brothers?

Virginia Woolf

When making a decision of minor importance, I have always found it advantageous to consider all the pros and cons. In vital matters, however, such as the choice of a mate or a profession, the decision should come from the unconscious, from somewhere within ourselves. In the important decisions of personal life, we should be governed, I think, by the deep inner needs of our nature.

Sigmund Freud

Writing, when properly managed (as you may be sure I think mine is) is but a different name for conversation.

Laurence Sterne

Think where man's glory most begins and ends, And say my glory was I had such friends.

William Butler Yeats

Dare to think for yourself.

Voltaire

If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.

Nikola Tesla

I am for doing good to the poor, but I differ in opinion about the means. I think the best way of doing good to the poor is not making them easy in poverty, but leading or driving them out of it.

Benjamin Franklin

For I am not so enamoured of my own opinions that I disregard what others may think of them.

Nicolaus Copernicus
