Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution.

Somewhere, something incredible is waiting to be known.

Knowledge will give you power, but character, respect.

I'm not a master, I'm a student-master, meaning that I have the knowledge of a master and the expertise of a master, but I'm still learning, So I'm a student-master. I don't believe in the word master, I consider the master as such when they close the casket.

As our circle of knowledge expands, so does the circumference of darkness surrounding it.

If I give you a pfennig, you will be one pfennig richer and I'll be one pfennig poorer. But if I give you an idea, you will have a new idea, but I shall still have it, too.

The further the spiritual evolution of mankind advances, the more certain it seems to me that the path to genuine religiosity does not lie through the fear of life, and the fear of death, and blind faith, but through striving after rational knowledge.

The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead, and his eyes are dimmed. It was the experience of mystery — even if mixed with fear — that engendered religion. A knowledge of the existence of something we cannot penetrate, our perceptions of the profoundest reason and the most radiant beauty, which only in their most primitive forms are accessible to our minds: it is this knowledge and this emotion that constitute true religiosity. In this sense, and only this sense, I am a deeply religious man.

You know, we don't grow most of the food we eat. We wear clothes other people make. We speak a language that other people developed. We use a mathematics that other people evolved... I mean, we're constantly taking things. It's a wonderful, ecstatic feeling to create something that puts it back in the pool of human experience and knowledge.

History is full of people who out of fear, or ignorance, or lust for power have destroyed knowledge of immeasurable value which truly belongs to us all. We must not let it happen again.

For in much wisdom is much grief; and he that increaseth knowledge increaseth sorrow.

I am satisfied with the mystery of life's eternity and with a knowledge, a sense, of the marvelous structure of existence — as well as the humble attempt to understand even a tiny portion of the Reason that manifests itself in nature.

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.

Knowledge is power.

The true delight is in the finding out rather than in the knowing.

If knowledge can create problems, it is not through ignorance that we can solve them.

When you make the finding yourself — even if you're the last person on Earth to see the light — you never forget it.

Those people who think they know everything are a great annoyance to those of us who do.

Those afraid of the universe as it really is, those who pretend to nonexistent knowledge and envision a Cosmos centered on human beings will prefer the fleeting comforts of superstition.

What we want is to see the child in pursuit of knowledge, and not knowledge in pursuit of the child.

For knowledge of the first principles, like space, time, motion, number, is as solid as any derived through reason, and it is on such knowledge, coming from the heart and instinct, that reason has to depend and base all its arguments.

Books permit us to voyage through time, to tap the wisdom of our ancestors. The library connects us with the insights and knowledge, painfully extracted from Nature, of the greatest minds that ever were, with the best teachers, drawn from the entire planet and from all of our history, to instruct us without tiring, and to inspire us to make our own contribution to the collective knowledge of the human species.

Someone who knows too much finds it hard not to lie.
