Science, like art, is not a copy of nature but a re-creation of her.
Science is a tribute to what we can know, although we are fallible.
Man masters nature not by force, but by understanding.
Time is not bought ready-made at the watchmaker’s.
Ask an impertinent question and you are on the way to the pertinent answer.
Power is the by-product of understanding.
Fifty years from now if an understanding of man’s origins, his evolution, his history, his progress is not in the common place of the school books we shall not exist.
In the moment of appreciation we live again the moment when the creator saw and held the hidden likeness.
This is the concentration camp and crematorium at Auschwitz. This is where people were turned into numbers. Into this pond were flushed the ashes of some four million people. And that was not done by gas. It was done by arrogance. It was done by dogma. It was done by ignorance. When people believe that they have absolute knowledge, with no test in reality, this is how they behave.
The creative personality is always one that looks on the world as fit for change and on himself as an instrument for change. Otherwise, what are you creating for? If the world is perfectly all right the way it is, you have no place in it. The creative personality thinks of the world as a canvas for change and of himself as a divine agent of change.
That is the essence of science: ask an impertinent question, and you are on the way to the pertinent answer.
We are nature’s unique experiment to make the rational intelligence prove itself sounder than the reflex. Knowledge is our destiny.
There are two parts to the human dilemma. One is the belief that the end justifies the means. That push-button philosophy, that deliberate deafness to suffering, has become the monster in the war machine. The other is the betrayal of the human spirit: the assertion of dogma that closes the mind, and turns a nation, a civilization, into a regiment of ghosts – obedient ghosts or tortured ghosts.
The University is a Mecca to which students come with something less than perfect faith. It is important that students bring a certain ragamuffin, barefoot irreverence to their studies; they are not here to worship what is known but to question it.
Freedom is valued in a culture that wants to encourage dissent and to stimulate originality and independence. It belongs to a society which is open to change, and which esteems the agent of change, the individual, above its own peace of mind.
The brain cannot reach its inner conclusions by any logic of certainty. In place of this, the brain must do two things. It must be content to accept less than certain knowledge. And it must have statistical methods which are different in kind from ours, by which it reaches its acceptable level of uncertainty. By these means, the brain constructs a picture of the world which is less than certain yet highly interlocked in its parts.
We treat ourselves both as objects of language and as speakers of language, both as objects of the symbolism and as symbols in it. And all the difficult paradoxes which go right back to Greek times and reappear in modern mathematics depend essentially on this.
There is one gift above all others that makes man unique among the animals, and it is the gift displayed everywhere here: his immense pleasure in exercising and pushing forward his own skill.
The poem and the drama is not the experience except as we identify ourselves with it, and know what it feels like to have it. What distinguishes literature is that it cannot be understood unless we understand what it is like to be human.
The most powerful drive in the ascent of man is his pleasure in his own skill. He loves to do what he does well and, having done it well, he loves to do it better. You see it in his science. You see it in the magnificence with which he carves and builds, the loving care, the gaiety, the effrontery. The monuments are supposed to commemorate kings and religions, heroes, dogmas, but in the end the man they commemorate is the builder.
You cannot love the girl without being conscious of the fact that she has yellow hair, you cannot see the world without the intervention of the physical senses.
