If I were again beginning my studies, I would follow the advice of Plato and start with mathematics.

It vexes me when they would constrain science by the authority of the Scriptures, and yet do not consider themselves bound to answer reason and experiment.

We must say that there are as many squares as there are numbers.

All truths are easy to understand once they are discovered; the point is to discover them.

By denying scientific principles, one may maintain any paradox.

Measure what is measurable, and make measurable what is not so.

Nature is relentless and unchangeable, and it is indifferent as to whether its hidden reasons and actions are understandable to man or not.

The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.

We cannot teach people anything; we can only help them discover it within themselves.

It is surely harmful to souls to make it a heresy to believe what is proved.

Where the senses fail us, reason must step in.

The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.

I've loved the stars too fondly to be fearful of the night.

The Bible shows the way to go to heaven, not the way the heavens go.

I have never met a man so ignorant that I couldn't learn something from him.

I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.

I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments, and demonstrations.

Facts which at first seem improbable will, even on scant explanation, drop the cloak which has hidden them and stand forth in naked and simple beauty.

In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.

If I were again beginning my studies, I would follow the advice of Plato and start with mathematics.

And yet it moves.

He who looks the higher is the more highly distinguished, and turning over the great book of nature (which is the proper object of philosophy) is the way to elevate one's gaze.

I give infinite thanks to God, who has been pleased to make me the first observer of marvelous things.

I notice that young men go to the universities in order to become doctors or philosophers or anything, so long as it is a title, and that many go in for those professions who are utterly unfit for them, while others who would be very competent are prevented by business or their daily cares, which keep them away from letters.

Philosophy is written in this grand book, the universe, which stands continually open to our gaze. But the book cannot be understood unless one first learns to comprehend the language and read the letters in which it is composed.

The nature of the human mind is such that unless it is stimulated by images of things acting upon it from without, all remembrance of them passes easily away.

Who would set a limit to the mind of man? Who would dare assert that we know all there is to be known?

The Bible shows the way to go to heaven not the way the heavens go.

All truths are easy to understand once they are discovered the point is to discover them.

Showing a greater fondness for their own opinions than for truth they sought to deny and disprove the new things which if they had cared to look for themselves their own senses would have demonstrated to them.

You cannot teach a man anything you can only help him find it within himself.

Holy Writ was intended to teach men how to go to Heaven not how the heavens go.

Mathematics is the key and door to the sciences.

What was observed by us in the third place is the nature or matter of the Milky Way itself, which, with the aid of the spyglass, may be observed so well that all the disputes that for so many generations have vexed philosophers are destroyed by visible certainty, and we are liberated from wordy arguments.

Measure what can be measured, and make measureable what cannot be measured.

You cannot teach a man anything, you can only help him find it within himself.

You cannot teach a man anything. You can only help him discover it within himself.

Women don't like advice. They don't want you to fix their problems, they just want you to listen.

I don't think a reporter should give advice or make predictions.

The only thing to do with good advice is to pass it on. It is never of any use to oneself.

Nobody can give you wiser advice than yourself.

No enemy is worse than bad advice.

I'm not in the business of becoming famous. And that's the advice I give to younger aspiring actors. Work onstage and do the little roles. In the end it's not important to be seen. It's important to do. There's a lot of disappointment in this business, but my family keeps me grounded.

Listen kid, take my advice, never hate a song that has sold half a million copies.

My advice to young film-makers is this: don't follow trends, start them!

There is nothing which we receive with so much reluctance as advice.

All of our affairs, since the union of crowns, have been managed by the advice of English ministers, and the principal offices of the kingdom filled with such men, as the court of England knew would be subservient to their designs.

To offer a man unsolicited advice is to presume that he doesn't know what to do or that he can't do it on his own.

But I try not to become preoccupied with that because with whatever direction I follow, with whatever advice I've followed or not followed, It's landed me in New York, in a very beautiful hotel, talking to people about something that I love. So I ain't that far off.
