There is today almost no scientific theory which was held when, say, the Industrial Revolution began about 1760. Most often today's theories flatly contradict those of 1760; many contradict those of 1900. In cosmology, in quantum mechanics, in genetics, in the social sciences, who now holds the beliefs that seemed firm sixty years ago? Yet the society of scientists has survived these changes without a revolution, and honors the men whose beliefs it no longer shares. No one has recanted abjectly at a trial before his colleagues. The whole structure of science has been changed and no one has been either disgraced or deposed. Through all the changes of science, the society of scientists is flexible and single-minded together, and evolves and rights itself. In the language of science, it is a stable society.

Science and the arts shared the same language at the Restoration. They no longer seem to do so today. But the reason is that they share the same silence: they lack the same language. And it is the business of each of us to make that one universal language which alone can unite art and science, and layman and scientist, in a common understanding.

Dream or nightmare, we have to live our experience as it is, and we have to live it awake. We live in a world which is penetrated through and through by science and which is both whole and real. We cannot turn it into a game simple by taking sides.

[To Esau] Jacob would reply: "My brother, there are two worlds before us, this world and the world to come. In this world, men eat and drink, and traffic and marry, and bring up sons and daughters, but all this does not take place in the world to come. If it please thee, do thou take this world, and I will take the other."

The discoveries of science, the works of art are explorations — more, are explosions, of a hidden likeness. The discoverer or the artist presents in them two aspects of nature and fuses them into one. This is the act of creation, in which an original thought is born, and it is the same act in original science and original art.

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.

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.

These are the moments when the powerful mind or the forceful character feels the ferment of the times, when his thoughts quicken, and when he can inject into the uncertainties of others the creative ideas which will strengthen them with purpose. At such a moment the man who can direct others, in thought or in action, can remake the world.

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.

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.

The force that makes the winter grow Its feathered hexagons of snow, and drives the bee to match at home Their calculated honeycomb, Is abacus and rose combined. An icy sweetness fills my mind, A sense that under thing and wing Lies, taut yet living, coiled, the spring.
