For evolutionary biologists, the concept of chance has always played a significant role in the formation of evolutionary theory. As far back as Greek antiquity, chance and "luck" were key factors in understanding the natural world. Chance is not just an important concept; it is an entire way of thinking about nature. And as Curtis Johnson shows, it is also one of the key ideas that separates Charles Darwin from other systematic biologists of his time. Studying the concept of chance (...) in Darwin's writing reveals core ideas in his theory of evolution, as well as his reflections on design, purpose, and randomness in nature's progression over the course of history.In Darwin's Dice: The Idea of Chance in the Thought of Charles Darwin, Curtis Johnson examines Darwin's early notebooks, his collected correspondence, and most of his published writing to trace the evolution of his ideas about chance in evolution. This proved to be one of Darwin's most controversial ideas among his reading public, so much so that it drew hostile reactions even from Darwin's scientific friends, not to mention the more general reader. The firestorm of criticism forced Darwin to forge a retreat, not in terms of removing chance from his theory--his commitment to it was unshakable--but in terms of how he chose to present his theory. Briefly, by changing his wording and by introducing metaphors and images, Darwin succeeded in making his ideas seem less threatening than before without actually changing his views. Randomness remained a focal point for Darwin throughout his life. Through the lens of randomness, Johnson reveals implications of Darwin's views for religion, free will, and moral theory. Darwin's Dice presents a new way to look at Darwinist thought and the writings of Charles Darwin. (shrink)

No single author presented Darwin with a more difficult question about his priority in discovering natural selection than the British comparative anatomist and paleontologist Richard Owen. Owen was arguably the most influential biologist in Great Britain in Darwin’s time. Darwin wanted his approbation for what he believed to be his own theory of natural selection. Unfortunately for Darwin, when Owen first commented in publication about Darwin’s theory of descent he was openly hostile. Darwin was taken off-guard. In private meetings and (...) correspondence prior to 1860 Owen had been nothing but polite and friendly, even helping Darwin in cataloguing and analyzing Darwin’s zoological specimens from the Beagle voyage. Every early indication predicted a life-long friendship and collaboration. But that was not to be. Owen followed his slashing review with a mounting campaign in the 1860s to denounce and discredit both Darwin and his small but ascendant circle of friends and supporters. But that was not enough for Owen. Starting in 1866, perhaps by now realizing Darwin had landed the big fish, Owen launched a new campaign, to claim the discovery of “Darwin’s theory” for himself. Darwin naturally fought back, mainly in the “Historical Sketch” that he prefaced to Origin starting in 1861. But when we peel back the layers of personal animus and escalating vituperation we discover in fact their quarrel was generated more by mutual misunderstanding than scientific disagreement. The battle ended only when Darwin finally penetrated to the crux of the matter and put an end to the rivalry in 1872, in the final version of the Sketch. (shrink)

Almost any modern reader's first encounter with Darwin's writing is likely to be the "Historical Sketch," inserted by Darwin as a preface to an early edition of the Origin of Species, and having since then appeared as the preface to every edition after the second English edition. The Sketch was intended by him to serve as a short "history of opinion" on the species question before he presented his own theory in the Origin proper. But the provenance of the "Historical (...) Sketch" is somewhat obscure. Some things are known about its production, such as when it first appeared and what changes were made to it between its first appearance in 1860 and its final form, for the fourth English edition, in 1866. But how it evolved in Darwin's mind, why he wrote it at all, and what he thought he was accomplishing by prefacing it to the Origin remain questions that have not been carefully addressed in the scholarly literature on Darwin I attempt to show that Darwin's various statements about the "Historical Sketch," made primarily to several of his correspondents between 1856 and 1860, are somewhat in conflict with one another, thus making problematic a satisfactory interpretation of how, when, and why the Sketch came to be. I also suggest some probable resolutions to the several difficulties. (shrink)

Charles Darwin's "Historical Sketch" has appeared as a preface to nearly every authorized edition of Darwin's Origin of Species since the second English edition was published in 1860. The "Historical Sketch" provides a brief history of opinion about the species question as a prelude to Darwin's own independent contribution to the subject, but its provenance is somewhat obscure. While some previous thinkers anticipated portions of Darwin's theory long before he did, none of them saw the complete picture as clearly as (...) Darwin. As such, he was able to claim originality and priority for the idea that has transformed our understanding of nature. His "Historical Sketch" was written as an attempt to address these issues. Some things are known about its production, such as when it first appeared and what changes were made to it between its first appearance in 1860 and its final form in 1866. Other questions remain unanswered. How did it evolve in Darwin's mind? Why did he write it at all? What did he think he was accomplishing by prefacing it to Origin of Species? Curtis Johnson approaches these questions, offering some clarity on the originality of Darwin's work. Darwin's "Historical Sketch" is the first comprehensive study of Darwin's "Preface" to Origin of Species. Johnson conveys the pressure Darwin felt from friends and other correspondents to showcase the originality of his theory, and he tackles questions of originality by carefully examining the 35 authors Darwin referenced in this monumental text.

Socrates and the Immoralists assembles an in-depth exploration of Socrates' argument for the just life, focusing specifically on the dialogues with the "immoralists" Polus, Callicles, and Thrasymachus, and illuminates the complexities of Socrates' thought, showing the interplay of the seemingly contradictory parts of Socrates' ambition, ultimately vindicating the overall coherence of his views.
