Occurence Quotes (3 quotes)

For deciding what has occurred and even what will occur, we have only to examine what is occurring.
In Theory of the Earth, from the original French, “Pour juger de ce qui est arrivé, et même de ce qui arrivera, nous n’avons qu’à examiner ce qui arrive.” Collected in Théorie de la Terre (1749), collected in Oeuvres Complètes de Buffon (1837), 42. As quoted and translated in Reijer Hooykaas, Selected Studies in History of Science (1983), 513. o2BGAAAAYAAJ - Translate this page Georges Louis Leclerc comte de Buffon - 1837

In the whole of geophysics there is probably hardly another law of such clarity and reliability as this—that there are two preferential levels for the world’s surface which occur in alternation side by side and are represented by the continents and the ocean floors, respectively. It is therefore very surprising that scarcely anyone has tried to explain this law.
In The Origins of Continents and Oceans (4th ed. 1929), trans. John Biram (1966), 37.

Spontaneous generation, to put the matter simply, takes place in smaller plants, especially in those that are annuals and herbaceous. But still it occasionally occurs too in larger plants whenever there is rainy weather or some peculiar condition of air or soil; for thus it is said that the silphium sprang up in Libya when a murky and heavy sort of wet weather condition occurred, and that the timber growth which is now there has come from some similar reason or other; for it was not there in former times.
De Causis Plantarum 1.5.1, in Robert Ewing Dengler (trans.) Theophrastus: De Causis Plantarum Book One: Text, Critical Apparatus, Translation, and Commentary, (1927), 31.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
