The interpretation of dreams is the royal road to a knowledge of the unconscious activities of the mind.

If you condemn painting, which is the only imitator of all visible works of nature, you will certainly despise a subtle invention which brings philosophy and subtle speculation to the consideration of the nature of all forms — seas and plains, trees, animals, plants and flowers — which are surrounded by shade and light. And this is true knowledge and the legitimate issue of nature; for painting is born of nature — or, to speak more correctly, we will say it is the grandchild of nature; for all visible things are produced by nature, and these her children have given birth to painting. Hence we may justly call it the grandchild of nature and related to God.

Leonardo da Vinci

So all a man could win in the conflict between plague and life was knowledge and memories.

The main things which seem to me important on their own account, and not merely as means to other things, are knowledge, art, instinctive happiness, and relations of friendship or affection.

Bertrand Russell

Of all the frictional resistances, the one that most retards human movement is ignorance, what Buddha called 'the greatest evil in the world.' The friction which results from ignorance... can be reduced only by the spread of knowledge and the unification of the heterogeneous elements of humanity. No effort could be better spent.

Absurd, irreducible; nothing — not even a profound and secret delirium of nature — could explain it. Obviously I did not know everything, I had not seen the seeds sprout, or the tree grow. But faced with this great wrinkled paw, neither ignorance nor knowledge was important: the world of explanations and reasons is not the world of existence. A circle is not absurd, it is clearly explained by the rotation of a straight segment around one of its extremities. But neither does a circle exist. This root, on the other hand, existed in such a way that I could not explain it.

Jean-Paul Sartre

The face of globalisation is contradictory. The internet and television can bring knowledge and information, but also offensive sexuality and mindless violence into the home. Trade can bring new wealth and opportunities, but also huge disruptions and change to communities. In all nations - including America - this change can bring fear. Fear that because of modernity we will lose of control over our economic choices, our politics, and most importantly our identities - those things we most cherish about our communities, our families, our traditions, and our faith. But I also know that human progress cannot be denied. There need not be contradictions between development and tradition.

No group and no government can properly prescribe precisely what should constitute the body of knowledge with which true education is concerned.

Franklin D. Roosevelt

Science may set limits to knowledge, but should not set limits to imagination.

Bertrand Russell

The idea of philosophy is a mysterious tradition. Philosophy is, in all, the problem of knowing. It is an undefined Science of the Sciences, a mysticism of the desire for knowledge; it is the very Spirit of the Sciences, and consequently unrepresentable, either in form or application, in the perfect representation of a special science.

The highest probability amounts not to certainty, without which there can be no true knowledge.

Every work of art is aggressive, Isabella. And every artist's life is a small war or a large one, beginning with oneself and one's limitations. To achieve anything you must first have ambition and then talent, knowledge, and finally the opportunity.

Carlos Ruiz Zafón

The plague of man is the opinion of knowledge. That is why ignorance is so recommended by our religion as a quality suitable to belief and obedience.

Michel de Montaigne

To know the mighty works of God, to comprehend His wisdom and majesty and power; to appreciate, in degree, the wonderful workings of His laws, surely all this must be a pleasing and acceptable mode of worship to the Most High, to whom ignorance cannot be more grateful than knowledge.

Nicolaus Copernicus

The journey will be difficult. The road will be long. I face this challenge with profound humility, and knowledge of my own limitations. But I also face it with limitless faith in the capacity of the American people. Because if we are willing to work for it, and fight for it, and believe in it, then I am absolutely certain that generations from now, we will be able to look back and tell our children that this was the moment when we began to provide care for the sick and good jobs to the jobless; this was the moment when the rise of the oceans began to slow and our planet began to heal; this was the moment when we ended a war and secured our nation and restored our image as the last, best hope on earth.

There are two methods of human activity - and according to which one of these two kinds of activity people mainly follow, are there two kinds of people: One use their reason to learn what is good and what is bad and they act according to this knowledge; the other act as they want to and then they use their reason to prove that that which they did was good and that which they didn't do was bad.

It is my inner conviction that the development of science seeks in the main to satisfy the longing for pure knowledge.

Albert Einstein

Knowledge is an excellent drug; but no drug has virtue enough to preserve itself from corruption and decay, if the vessel be tainted and impure wherein it is put to keep.

Michel de Montaigne

Concerning the Gods, there are who deny the very existence of the Godhead; others say that it exists, but neither bestirs nor concerns itself nor has forethought for anything. A third party attribute to it existence and forethought, but only for great and heavenly matters, not for anything that is on earth. A fourth party admit things on earth as well as in heaven, but only in general, and not with respect to each individual. A fifth, of whom were Ulysses and Socrates, are those that cry:— I move not without Thy knowledge!

Suddenly Faramir stirred, and he opened his eyes, and he looked on Aragorn who bent over him; and a light of knowledge and love was kindled in his eyes, and he spoke softly. 'My lord, you called me. I come. What does the king command?

J. R. R. Tolkien
