The title of Queen rang sweet to my ears, child though I was.... This idea of a crown began running in my head then like a tune, and has been running a lot in it ever since.

Catherine the Great

So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.

Nicolaus Copernicus

If you reject absolutely any single sensation without stopping to discriminate with respect to that which awaits confirmation between matter of opinion and that which is already present, whether in sensation or in feelings or in any immediate perception of the mind, you will throw into confusion even the rest of your sensations by your groundless belief and so you will be rejecting the standard of truth altogether. If in your ideas based upon opinion you hastily affirm as true all that awaits confirmation as well as that which does not, you will not escape error, as you will be maintaining complete ambiguity whenever it is a case of judging between right and wrong opinion.

I have not yet learned to live, that I can see, and I fear that I shall not very soon. I find, however, that in the long run things correspond to my original idea,--that they correspond to nothing else so much; and thus a man may really be a true prophet without any great exertion. The day is never so dark, nor the night even, but that the laws at least of light still prevail, and so may make it light in our minds if they are open to the truth.

Henry David Thoreau

I'm gradually managing to cram my mind more and more full of things. I've got this beautiful mind and it's going to die, and it'll all be gone. And then I say, not in my case. Every idea I've ever had I've written down, and it's all there on paper. And I won't be gone; it'll be there.

Let us leave every man at liberty to seek into him and to lose himself in his ideas.

But of all other ideas, it is number, which I think furnishes us with the clearest and most distinct idea of infinity we are capable of.

When at last in a race a new principle appears, an idea--that conserves it; ideas only save races.

Ralph Waldo Emerson

And I can tell you as a friend that sustainable prosperity in the 21st century depends upon education, health care, and environmental protection. But it also depends on the free and open exchange of ideas. If you can't access information online, if you cannot be exposed to different points of view, you will not reach your full potential. And over time, the youth will lose hope.

I am not saying goodbye to you. I only wish to fight as a soldier of ideas.

The idea that physicists would in future have to study the theory of tensors created real panic amongst them following the first announcement that Einstein's predictions had been verified.

Bertrand Russell

I do not wish to be misunderstood upon this subject of slavery in this country. I suppose it may long exist, and perhaps the best way for it to come to an end peaceably is for it to exist for a length of time. But I say that the spread and strengthening and perpetuation of it is an entirely different proposition. There we should in every way resist it as a wrong, treating it as a wrong, with the fixed idea that it must and will come to an end.

Abraham Lincoln

Every person has his own ideas of the act of praying for God's guidance, tolerance, and mercy to fulfill his duties and responsibilities. My own concept of prayer is not as a plea for special favors nor as a quick palliation for wrongs knowingly committed. A prayer, it seems to me, implies a promise as well as a request; at the highest level, prayer not only is a supplication for strength and guidance, but also becomes an affirmation of life and thus a reverent praise of God.

The key to every man is his thought. Sturdy and defying though he look, he has a helm which he obeys, which is the idea after which all his facts are classified. He can only be reformed by showing him a new idea which commands his own.

Ralph Waldo Emerson

Tools arm the man. One can well say that man is capable of bringing forth a world; he lacks only the necessary apparatus, the corresponding armature of his sensory tools. The beginning is there. Thus the principle of a warship lies in the idea of the shipbuilder, who is able to incorporate this thought by making himself into a gigantic machine, as it were, through a mass of men and appropriate tools and materials. Thus the idea of a moment often required monstrous organs, monstrous masses of materials, and man is therefore a potential, if not an actual creator.

Whenever I publish a book, I feel like a trapper caught by the Iroquois. They're all lined up with Tomahawks, and the idea is to run through with your head down, and everybody gets to take a swing. They hit you in the head, the back, the ass, and the balls.

That faith makes blessed under certain circumstances, that blessedness does not make of a fixed idea a true idea, that faith moves no mountains but puts mountains where there are none: a quick walk through a madhouse enlightens one sufficiently about this.

Friedrich Nietzsche

An idea that is not dangerous is unworthy of being called an idea at all.

Abandon fancy theologies and imaginary ideas and do some ordinary daily work... {Engage in this work with} unswerving kindness and unending patience.

The idea of an all-powerful divine Being is present everywhere, unconsciously if not consciously, because it is an archetype. There is in the psyche some superior power, and if it is not consciously a god, it is the "belly" at least, in St. Paul's words. I therefore consider it wiser to acknowledge the idea of God consciously, for, if we do not, something else is made God, usually something quite inappropiate and stupid such as only an "enlightened" intellect could hatch forth.

I understand where Bill Maher is coming from when he says, basically, the world is destroying itself over a bunch of fairy tales about talking snakes and men who are alive inside fishes. I'm very sympathetic to it, but at the same time, given the cosmos that we're living in, it's very persuasive, the idea that there is some kind of first cause that's running things. It might not be the god of Jerry Jenkins and Tim LaHaye, it might not be the god of al-Qaida, and it might not be the god of Abraham, but something very well could be running things. The order of the universe as we see it, the interlocking nature, and the way things work together, are persuasive of the idea that there may be some overarching first cause.

In so doing, the idea forces itself upon him that religion is comparable to a childhood neurosis, and he is optimistic enough to suppose that mankind will surmount this neurotic phase, just as so many children grow out of their similar neurosis.

At the times in my life when I was feeling the most gregarious and looking for bosom friendships, I couldn't find any takers so that exactly when I was alone was when I felt the most like not being alone. The moment I decided I'd rather be alone and not have anyone telling me their problems, everybody I'd never even seen before in my life started running after me to tell me things I'd just decided I didn't think it was a good idea to hear about. As soon as I became a loner in my own mind, that's when I got what you might call a "following." As soon as you stop wanting something you get it. I've found that to be absolutely axiomatic.

If you wish to gain an idea of what revolution is, call it Progress; and if you wish to acquire an idea of the nature of progress, call it To-morrow.

We have to put a stop to the idea that it is a part of everybody's civil rights to say whatever he pleases.
