Jacob Bronowski Quotes

My view is that diversity is the breath of life, and we must not abandon that for any single form which happens to catch our fancy – even our genetic fancy. Cloning is the stabilisation of one form, and that runs against the whole current of creation – of human creation above all. Evolution is founded in variety and creates diversity; and of all animals, man is most creative because he carries and expresses the largest store of variety. Every attempt to make us uniform, biologically, emotionally, or intellectually, is a betrayal of the evolutionary thrust that has made man its apex.

And Mendeleev’s guesses showed that induction is a more subtle process in the hands of a scientist than Bacon and other philosophers supposed. In science we do not simply march along a linear progression of known instances to unknown ones. Rather, we work as in a crossword puzzle, scanning two separate progressions for the points at which they intersect: that is where the unknown instances should be in hiding. Mendeleev scanned the progression of atomic weights in the columns, and the family likenesses in the rows, to pinpoint the missing elements at their intersections. By doing so, he made practical predictions, and he also made manifest (what is still poorly understood) how scientists actually carry out the process of induction.

But war, organized war, is not a human instinct. It is a highly planned and cooperative form of theft. And that form of theft began ten-thousand years ago when the harvesters of wheat accumulated a surplus and the nomads rose out of the desert to rob them of what they themselves could not provide.

These frozen faces, these frozen frames in a film that is running down, mark a civilisation which failed to take the first step on the ascent of rational knowledge. That is the failure of the New World cultures, dying in their own symbolic Ice Age.

"We cannot separate the special importance of the visual apparatus of man from his unique ability to imagine, to make plans, and to do all the other things which are generally included in the catchall phrase "free will." What we really mean by free will, of course, is the visualizing of alternatives and making a choice between them. In my view, which not everyone shares, the central problem of human consciousness depends on this ability to imagine."

power is the by-product of understanding. So the Greeks said that Orpheus played the lyre with such sympathy that wild beasts were tamed by the hand on the strings. They did not suggest that he got this gift by setting out to be a lion tamer.

[When] we practice science (and this is true of all our experience), we are always decoding a part of nature which is not complete. We simply cannot get out of our own finiteness.

It's said that science will dehumanize people and turn them into numbers. That's false, tragically false. Look for yourself. 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. This is what men do when they aspire to the knowledge of gods.

Knowledge … is an unending adventure at the edge of uncertainty.

cultural evolution; once it takes off, it goes as the ratio of those two numbers goes, at least a hundred times faster than biological evolution.

But it is of critical importance to ask ourselves what features which other animals do not possess have given human beings the very special capacities with which we are concerned in these lectures: the ability to utter cognitive sentences (which no other animal can do) and the ability therefore to exercise knowledge and imagination.

Todas as modalidades de amostragem fornecem apenas uma informação provável a respeito da população da qual se extraiu a amostra. Ao provar uma teoria científica pela experimentação, procuramos informar-nos sobre um conjunto de ocorrências naturais, por meio de uma amostra, convencendo-nos de que o universo considerado se conforma com as configurações geradas pelo modelo que adotamos, em toda a sua extensão. Muitas asneiras têm sido ditas a respeito da probabilidade na ciência pelos que não compreendem esta concepção. Há filósofos que falam em “teorias prováveis”, e outros chegam a falar como se os fatos pudessem ser prováveis. Os fatos existem ou não

The world today is made, it is powered by science; and for any man to abdicate an interest in science is to walk with open eyes towards slavery.

There are many gifts that are unique in man; but at the centre of them all, the root from which all knowledge grows, lies the ability to draw conclusions from what we see to what we do not see, to move our minds through space and time, and to recognise ourselves in the past on the steps to the present. All over these caves the print of the hand says: ‘This is my mark. This is man.

Now if Newton had been a very plain, very dull, very matter-of-fact man, all that would be easily explicable. But I must make you see that he was not. He was really a most extraordinary, wild character. He practised alchemy. In secret, he wrote immense tomes about the Book of Revelation. He was convinced that the law of inverse squares was really already to be found in Pythagoras. And for such a man, who in private was full of these wild metaphysical and mystical speculations, to hold this public face and say, ‘I make no hypotheses’ – that is an extraordinary expression of his secret character. William Wordsworth in The Prelude has a vivid phrase, Newton, with his prism and silent face, which sees and says it exactly. Well,
