Geology Quotes

“But just in proportion as this process of extermination has acted on an enormous scale, so must the number of intermediate varieties, which have formerly existed, be truly enormous. Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduated organic chain; and this, perhaps, is the most obvious and serious objection which can be urged against the theory. The explanation lies, as I believe, in the extreme imperfection of the geological record.”

“Father Nicholas Steno, is often identified as the father of geology.”

“It was during my enchanted days of travel that the idea came to me, which, through the years, has come into my thoughts again and again and always happily—the idea that geology is the music of the earth.”

“Ahead and to the west was our ranger station - and the mountains of Idaho, poems of geology stretching beyond any boundaries and seemingly even beyond the world.”

“Much as I admired the elegance of physical theories, which at that time geology wholly lacked, I preferred a life in the woods to one in the laboratory.”

“[In geology,] As in history, the material in hand remains silent if no questions are asked. The nature of these questions depends on the 'school' to which the geologist belongs and on the objectivity of his investigations. Hans Cloos called this way of interrogation 'the dialogue with the earth,' 'das Gesprach mit der Erde.”

“The scientific world of the time was in the midst of a terrible ferment, with discoveries and realizations coming at an unseemly rate. To many in the ranks of the conservative and the devout, the new theories of geology and biology were delivering a series of hammer blows to mankind's self-regard. Geologists in particular seemed to have gone berserk, to have thrown off all sense of proper obeisance to their Maker... Mankind, it seemed, was now suddenly rather – dare one say it? – insignificant. He may not have been, as he had eternally supposed, specially created.”

“Amidst the vicissitudes of the earth's surface, species cannot be immortal, but must perish, one after another, like the individuals which compose them. There is no possibility of escaping from this conclusion.”

“The tendency to variation in living beings, which all admitted as a matter of fact; the selective influence of conditions, which no one could deny to be a matter of fact, when his attention was drawn to the evidence; and the occurrence of great geological changes which also was matter of fact; could be used as the only necessary postulates of a theory of the evolution of plants and animals which, even if not at once, competent to explain all the known facts of biological science, could not be shown to be inconsistent with any.”
