Quotes from Jacob Bronowski

Every animal leaves traces of what it was; man alone leaves traces of what he created.

The world can only be grasped by action, not by contemplation. The hand is the cutting edge of man.

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.

Science, like art, is not a copy of nature but a re-creation of her.

Many theories of the ancient world seem terribly childish today, a hodge-podge of fables and false comparisons.But our theories will seem childish five-hundred years from now.Every theory is based on some analogy, and sooner or later the theory fails because the analogy turns out to be false. A theory in its day helps to solve the problems of the day.

The richness of human life is that we have many lives; we live the events that do not happen (and some that cannot) as vividly as those that do; and if thereby we die a thousand deaths, that is the price we pay for living a thousand lives.

The values by which we are to survive are not rules for just and unjust conduct, but are those deeper illuminations in whose light justice and injustice, good and evil, means and ends are seen in fearful sharpness of outline.

The act of imagination is the opening of the system so that it shows new connections. Every act of act of imagination is the discovery of likenesses between two things which were thought unlike. An example is Newton's thinking of the likeness between the thrown apple and moon sailing majestically in the sky. Hence, the 'discovery' of the laws of gravity.

Man is unique not because he does science, and he is unique not because he does art, but because science and art equally are expressions of his marvellous plasticity of mind.

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.

And when we describe it as I shall do, it becomes plain that imagination is a specifically human gift. To imagine is the characteristic act, not of the poet's mind, or the painter's, or the scientist's, but of the mind of man.

That is the essence of science: ask an impertinent question, and you are on the way to the pertinent answer.

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.

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 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.

We are nature's unique experiment to make the rational intelligence prove itself sounder than the reflex. Knowledge is our destiny

we must always remember that the real content of evolution (biological as well as cultural) is the elaboration of new behaviour.

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.

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.

All those formal systems, in mathematics and physics and the philosophy of science, which claim to give foundations for certain truth are surely mistaken. I am tempted to say that we do not look for truth, but for knowledge. But I dislike this form of words, for two reasons. First of all, we do look for truth, however we define it, it is what we find that is knowledge. And second, what we fail to find is not truth, but certainty; the nature of truth is exactly the knowledge that we do find.

what we call cultural evolution is essentially a constant growing and widening of the human imagination.

Dissent is the mark of freedom.

Every animal leaves traces of what it was; man alone leaves traces of what he created.

The child is not a prisoner of its inheritance; it holds its inheritance as a new creation which its future actions will unfold.
