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 poem or the discovery exists in two moments of vision: the moment of appreciation as much as that of creation; for the appreciator must see the movement, wake to the echo which was started in the creation of the work. In the moment of appreciation we live again the moment when the creator saw and held the hidden likeness. When a simile takes us aback and persuades us together, when we find a juxtaposition in a picture both odd and intriguing, when a theory is at once fresh and convincing, we do not merely nod over someone else's work. We re-enact the creative act, and we ourselves make the discovery again...

...Reality is not an exhibit for man's inspection, labeled: "Do not touch." There are no appearances to be photographed, no experiences to be copied, in which we do not take part.

And the great poem and the deep theorem are new to every reader, and yet are his own experiences, because he himself re-creates them. They are the marks of unity in variety; and in the instant when the mind seizes this for itself, in art or in science, the heart misses a beat."
