Time's Arrow, Time's Cycle: Myth and Metaphor in the Discovery of Geological Time,

Does history repeat itself or does it generate a sequence of unique events? This is the fundamental question "Time's Arrow and Time's Cycle" asks. It is my third favourite Gould book, after "Wonderful Life" and "Bully for Brontosaurus". From a literary and philosophical point of view, it's possibly his best book, being more tightly focused than WL and more developed than the essays in BfB. You'll find here many standard Gould devices such as fascinating segues and the rehabilitation of discredited thinkers. For instance we read the story of how James Hampton built his masterpiece, his throne to the glory of God, out of discarded junk (it's now at the Smithsonian). Gould also rehabilitates the 17th century thinker Thomas Burnet and his unsubstantiated cosmological theories. He also presents two more orthodox thinkers, James Hutton and Charles Lyell, and contrasts their gradual uniformitarianism with the sudden catastrophism of Burnet. Gould explicitly dismisses Burnet's scientific credentials but still uses Burnet's vision as a starting point. It is by opposing Burnet to Hutton and Lyell that Gould asks the question as to what history is: repetive and uniform, or cyclical? The answer of course is a little of both. Again, Burnet's vision provides the clue to the answer. There are cycles, and within the cycle there are shocks and catastrophes. Or is it the other way around? Clearly Time is a difficult concept to grasp! Vincent Poirier, Tokyo

Time's Arrow Time's Cycle written by Stephtn Jay Gould is a book that takes human thought to a new level in comprehending geology's vastness of history... the discovery of deep time. Gould works this book's major theme in the role of metaphor in the formulation and testing of scientific theories as the directionality (narrative history) of time's arrow or the immanence of time's cycle (immanent laws).This book is both an account of geology's greatest discovery and philosophical commentary on the nature of scientific thought. As this thought takes us from thought of time in thousand of years to billions of years, inspired by empirical observation of rocks in the field.Gould follows a single thread through three documents that mark the transition in our thinking: Thomas Burnet's four-volume "Sacred Theory of the Earth" (1680-1690), James Hutton's "Theory of the Earth (1795), and Charle Lyell's three-volume "Principle of Geology (1830-1833). Gould shifts through these writings giving the reader a history and background needed for a progressive march to the truth of the geological history through an enlightened observation.Reading this book will captivate the curious reader and helps the human mind understand the vastness of time and the struggle to understand it.

The title of the review is an homage to Gould's oft mentioned love of baseball. This book is a cogent explanation of how European scientists (natural philosophers) recounciled the narrative tradition of history inherited from the Judeo-Christian template with the eternal return perspective of the Classical civilizations. Both view points-as-metaphors shed light on interpretation of the geological record. There are both serial and cyclic elements in the history of the earth, so the scientific community found truth in spite of the fact that individual scientists tended to emphasize one perspective over the other.Gould exposes the 'cardboard cut-out' Whig version of history that most working scientists have received uncritically as hurried historical preambles to their study of geology per se. James Hutton, for example, is held up as a paragon of the field geologist who supposedly preceded his assertion of the existence of 'deep time' with countless hours in the field. Not so, says Gould. In fact, Hutton did his field work after he conceived the idea of a lengthy earth history and merely used his field observations to bolster his claim. Thomas Burnet, author of the much made-fun-of Sacred Theory of the Earth, is revealed to have been a champion of uniformitarianism before Hutton even conceived of it. Burnet refused to advance causes for events described in the Bible that could not be explained by the laws of physics as advanced by Isaac Newton. Finally, Charles Lyell is exposed as a master of rhetoric who conflated methodological and substantive aspects of uniformitarianism in order to sway his audience. No member of the scientific community contemporary to Lyell clung to the Mosaic timescale. He merely used it as a strawman. It was Lyell who managed to mate the narrative and eternal return perspectives into a coherent view of Earth history. First he did so by insisting the apparent progress observed in the fossil record was caused by the immense scale of the cycles of Earth history. Eventually he conceded the reality of evolution and allowed for the existence of an arrow of time whose path did not curve.Gould's book is modified from a series of lectures, which is probably why there is so much uncharacteristic repetition of themes and ideas in this book. It was the only aspect of this book that I found irritating. Gould is also candid about his pride at uncovering various inaccuracies in the received wisdom and unearthing original themes to explain patterns in the history of geology. I have heard other people complain about this personality trait. I have no problem with it and believe that his satisfaction with his own cleverness is quite justifiable.

Stephen Jay Gould's love of science history really shows through in this work, which focuses on changing ideas about time and geology. It's well-researched and makes some very intriguing points about science in general, but if you have no patience for geology you probably won't get that far - it's nowhere near as accessible as his essay collections, but that's only to be expected. Every science major should read this book, and so should anyone who likes to think of themselves as well-informed about history and science.
