Charles Lyell on History

"We find in certain localities subterranean deposits of coal consisting of vegetable matter formerly drifted into seas and lakes. ...These seas and The commercial prosperity and numerical strength of a nation may now be mainly dependent on the local distribution of fuel determined by that ancient state of things."

"A sketch of the progress of Geology is the history of a constant and violent struggle between new opinions and ancient doctrines sanctioned by the implicit faith of many generations and supposed to rest on scriptural authority. The inquiry, therefore, although highly interesting to one who studies the philosophy of the human mind, is singularly barren of instruction to him who searches for truths in physical science."

"In my account of his theory, I did not, at the time, fully appreciate the deep conviction which it displays of the slow manner in which geological changes have taken place, and the insignificance of thirty or forty centuries in the history of a species, and that, too, at a period when very narrow views were entertained of the extent of past time by most of the ablest geologists, and when great revolutions of the earth's crust, and its inhabitants, were generally attributed to sudden and violent catastrophes."

"It was long ere the distinct nature and legitimate objects of geology were fully recognized, and it was at first confounded with many other branches of inquiry, just as the limits of history, poetry, and mythology were ill-defined in the infancy of civilization. Werner appears to have regarded geology as little other than a subordinate department of mineralogy and Desmarest included it under the head of Physical Geography. ...The first who endeavored to draw a clear line of demarcation between these distinct departments, was Hutton, who declared that geology was in no ways concerned with 'questions as to the origin of things.'"
