" "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

Additional quotes by Jacob Bronowski
The genius of men like Newton and Einstein lies in that: they ask transparent, innocent questions which turn out to have catastrophic answers. The poet William Cowper called Newton a ‘childlike sage’ for that quality, and the description perfectly hits the air of surprise at the world that Einstein carried in his face. Whether he talked about riding a beam of light or falling through space, Einstein was always full of beautiful, simple illustrations of such principles, and I shall take a leaf out of his book. I go to the bottom of the clocktower, and get into the tram he used to take every day on his way to work as a clerk in the Swiss Patent Office.
The fact is that there are two traditions of explanation that march side by side in the ascent of man. One is the analysis of the physical structure of the world. The other is the study of the processes of life: their delicacy, their diversity, the wavering cycles from life to death in the individual and in the species. And these traditions do not come together until the theory of evolution; because until then there is a paradox which cannot be resolved, which cannot be begun, about life.
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.
