Scriptural geologist
Scriptural geologists were a heterogeneous group of writers in the early nineteenth century, who claimed "the primacy of literalistic biblical exegesis" and a short Young Earth time-scale. Their views were marginalised and ignored by the scientific community of their time. They "had much the same relationship to 'philosophical' geologists as their indirect descendants, the twentieth-century creationists." Paul Wood describes them as "mostly Anglican evangelicals" with "no institutional focus and little sense of commonality". They generally lacked any background in geology, and had little influence even in church circles.
Background
Reason for appearance
Up until the end of the 18th century Classical British scholarship was theologically based, using the Bible as a basic source for world history and chronology. Early work in the developing science of geology sought "theories of the Earth" combining mechanical physical laws in the natural philosophy of René Descartes with belief in the global flood described in Genesis. The Genesis Flood was given serious consideration as a basis for explaining geological data, and though by 1800 naturalists accepted an old-earth cosmology, this was not an inevitable conclusion among the educated. Amateur and popular geologists continued to use scripture centred geology well into the 19th century.In the 18th century, geologists became convinced that an immense time had been needed to build up the huge thickness of rock strata visible in quarries and cliffs, implying extensive pre-human periods. The concept of Neptunism taught by Abraham Gottlob Werner proposed that rock strata had been deposited from a primeval global ocean rather than by Noah's Flood. Opposing this, James Hutton proposed an indefinitely old cycle of eroded rocks being deposited in the sea, consolidated and heaved up by volcanic forces into mountains which in turn eroded, all in natural processes which continue to operate.
By 1807 when the Geological Society of London was founded as the first professional geological society, most of its members accepted a basic geologic time scale, and researchers including William Smith had found that strata could be identified by characteristic fossils.
Theologians sought to reconcile scripture, the book of God's word, with natural history, the book of God's works. Thomas Chalmers popularised Gap creationism, a form of old Earth creationism that posits that the six-day creation as described in the Book of Genesis involved literal 24-hour days, but that there was a gap of time between two distinct creations in the first and the second verses of Genesis, explaining many scientific observations, including the age of the Earth. Chalmers' suggestion was supported by theological liberals, what Milton Millhauser referred to as the party of "reconciliation," such as Edward Hitchcock, W. D. Conybeare, and the future Cardinal Wiseman. Sharon Turner included it in his children's book A Sacred History of the World. Millhauser wrote that "Its prestige was such that the " interval" theory presently became almost the official British rival to the continental one that interpreted the Six Days as six creative eras," adding his subjective estimate that "until about 1850, the casual pulpit or periodical assurance that geology does not conflict with revelation was based, in possibly seven instances out of ten, on Chalmers' "interval" theory."
The research of Georges Cuvier indicated "repeated irruptions and retreats of the sea" which he identified with a long series of sudden catastrophes which had caused extinctions: when this was translated into English in 1813, Robert Jameson added suggestions that the last catastrophe was the biblical Deluge. The Church of England clergyman William Buckland became the foremost proponent of Flood geology, proposing in 1819 that certain surface features were evidence of violent flooding during the Deluge as the last of a series of catastrophes.
Historian of Religion Arthur McCalla considers that "All geological work that was taken seriously by experts took for granted the reality of deep time" and that scriptural geologists were not given "the slightest credence" by working geologists. Ralph O'Connor, a history professor at the University of Aberdeen, considers McCalla's views to be an "overstatement", and states that "the 'orthodoxy' of an old-earth cosmology was not there for the taking; it had to be painstakingly constructed, using various performance strategies designed to persuade the literate classes that the new school of geology trumped biblical exegesis in questions about earth history."
The British scriptural geologists' writings came in two waves. The first, in the 1820s, was in response to 'gap theory' and included Granville Penn's A Comparative Estimate of the Mineral and Mosaical Geologies and George Bugg's Scriptural Geology. Realizing that the majority opinion was slipping away from scriptural geology, their zeal increased. While the period from 1815-1830 represents the incubation of the movement, 1830 to 1844 marks its most intense and significant activity. This was largely in response to Charles Lyell's Principles of Geology and Buckland's Bridgewater Treatise, Geology and Mineralogy considered with reference to Natural Theology, which retracted his earlier ideas that flood geology had found evidence of a universal flood. Responses included George Fairholme's General View of the Geology of Scripture and The Mosaic Deluge.
O'Connor wrote of the times that, "Although secularization in various forms was on the ascendant among the upper and upper-middle classes, the Bible was still the most important book in early nineteenth-century British cultural life. Although liberalizing churchmen were busily instructing people that the Bible was not intended to teach facts about the natural world, the text of Genesis 1 appeared on the face of it to suggest otherwise, with its bald statements of what had been created when. For all but a growing minority, the Bible remained a vital touchstone for speculation about the natural world; conversely, any thoughtful reading of the first few chapters of Genesis necessarily involved reflections about the natural world."
Geological competence
Professor of intellectual history David N. Livingstone states that scriptural geologists "were not, as it turns out, geologists at all", concluding that "while it may be proper to speak of Scriptural Geology, it is not really accurate to speak of Scriptural Geologists." L. Piccardi and W. Bruce Masse state that "part from George Young, none of these scriptural geologists had any geological competence". David Clifford states that they were "not themselves geologists" but rather "keen but biased amateurs" and that one of them, James Mellor Brown, "felt that no scientific expertise was required when examining scientific matters." Taking a more positive view, Milton Millhauser states that the leaders of the party were "by no means ignorant of the science assailed."O'Connor argues that terminology in the 21st-century is a stumbling-block to modern analysis of geologic competence of the scriptural geologists because science today is understood in the language of Lyell and Darwin rather than that of Penn and Fairholme. Scriptural geologists saw themselves as 'geologists' and valued geologic fieldwork. Biblical exegesis, too, was central to science in general and earth history in particular. For the educated of the early 19th-century the Bible was itself valuable evidence. Evidence does not speak for itself, but requires interpretation. A heap of strata, or a line of Hebrew, is interpreted in various ways. To use the words 'geology' or 'science' in the 21st century sense automatically excludes Scriptural geologist perspectives on this debate, and skews the discussion from the start.
They have been described as "genteel laymen... versed in polite literature; clergymen, linguists, and antiquaries—those, in general, with vested interests in mediating the meaning of books, rather than rocks, in churches and classrooms", although a number of them were involved in fossil collecting or scientific endeavours. However, for the majority, geology was not their main scientific interest, but rather a transient or peripheral concern.
