Uniformitarianism Quotes (8 quotes)

If catastrophic geology had at times pushed Nature to almost indecent extremes of haste, uniformitarian geology, on the other hand, had erred in the opposite direction, and pictured Nature when she was “young and wantoned in her prime”, as moving with the lame sedateness of advanced middle age. It became necessary, therefore, as Dr. Haughton expresses it, “to hurry up the phenomena”.
From British Association Address to Workingmen, 'Geology and Deluges', published in Nature (1984), 50, 505-510. Also printed in Popular Science Monthly (Dec 1894), 46 251. “Wontoned” (sic) was likely used for “wanton.” and Dr. Samuel Haughton was an Irish scientific writer —Webmaster.

In using the present in order to reveal the past, we assume that the forces in the world are essentially the same through all time; for these forces are based on the very nature of matter, and could not have changed. The ocean has always had its waves, and those waves have always acted in the same manner. Running water on the land has ever had the same power of wear and transportation and mathematical value to its force. The laws of chemistry, heat, electricity, and mechanics have been the same through time. The plan of living structures has been fundamentally one, for the whole series belongs to one system, as much almost as the parts of an animal to the one body; and the relations of life to light and heat, and to the atmosphere, have ever been the same as now.
In Manual of Geology, Treating of the Principles of the Science (1863), 7.

Mr Hall's hypothesis has its cause for subsidence, but none for the lifting of the thickened sunken crust into mountains. It is a theory for the origin of mountains, with the origin of mountains left out.
In 'Observations on the Origin of Some of the Earth's Features', The American Journal of Science (Sep 1866), Second Series, 42, No. 125, 210.

Palaeontologists cannot live by uniformitarianism alone. This may be termed the Phenomenon of the Fallibility of the Fossil Record.
In The Nature of the Stratigraphical Record (1973), 26.

Time is in itself [not] a difficulty, but a time-rate, assumed on very insufficient grounds, is used as a master-key, whether or not it fits, to unravel all difficulties. What if it were suggested that the brick-built Pyramid of Hawara had been laid brick by brick by a single workman? Given time, this would not be beyond the bounds of possibility. But Nature, like the Pharaohs, had greater forces at her command to do the work better and more expeditiously than is admitted by Uniformitarians.
'The Position of Geology', The Nineteenth Century (1893), 34, 551.

With the sole guidance of our practical knowledge of those physical agents which we see actually used in the continuous workings of nature, and of our knowledge of the respective effects induced by the same workings, we can with reasonable basis surmise what the forces were which acted even in the remotest times.
Quoted in Francesco Rodolico, 'Arduino', In Charles Coulston Gillispie (ed.), Dictionary of Scientific Biography (1970), Vol. 1, 234.

[My Book] will endeavour to establish the principle[s] of reasoning in ... [geology]; and all my geology will come in as illustration of my views of those principles, and as evidence strengthening the system necessarily arising out of the admission of such principles, which... are neither more nor less than that no causes whatever have from the earliest time to which we can look back, to the present, ever acted, but those now acting; and that they never acted with different degrees of energy from that which they now exert.
Letter to Roderick Murchison Esq. (15 Jan 1829). In Mrs Lyell (ed.), The Life, Letters and Journals of Sir Charles Lyell, Bart (1881), Vol. 1, 234.

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
