Darwin’s two theories, 1844 and 1859

Derek Partridge

Abstract Darwin’s first two, relatively complete, explicit articulations of his theorizing on evolution were his Essay of 1844 and On the Origin of Species published in 1859. A comparative analysis concludes that they espoused radically different theories despite exhibiting a continuity of strategy, much common structure and the same key idea. Both were theories of evolution by means of natural selection. In 1844, organic adaptation was confined to occasional intervals initiated and controlled by de-stabilization events. The modified descendants rebalanced the particular “plant and animal forms … unsettled by some alteration in their circumstances.” But by 1859, organic adaptation occurred continuously, potentially modifying the descendants of all organisms. Even natural selection, the persistent core of Darwin’s theorizing, does not prove to be a significant basis for theory similarity. Consequently, Darwin’s Origin theory cannot reasonably be considered as a mature version of the Essay. It is not a modification based on adjustments, further justifications and the integration of a Principle of Divergence. The Origin announced a new “scientific paradigm” while the Essay did little more than seemingly misconfigure the operation of a novel mechanism to extend varieties beyond their accepted bounds, and into the realm of possible new species. Two other collections of Darwin’s theorizing are briefly considered: his extensive notes of the late 1830s and his contributions to the famous meeting of 1 July 1858. For very different reasons, neither constitutes a challenge to the basis for this comparative study. It is concluded that, in addition to the much-debated social pressures, an unacknowledged further reason why Darwin did not publish his theorizing until 1859, could have been down to his perceptive technical judgement: wisely, he held back from rushing to publish demonstrably flawed theorizing.

Comparing the respective transmutation mechanisms of Patrick Matthew, Charles Darwin and Alfred Wallace

Joachim L Dagg

Abstract A comparison of the evolutionary mechanisms of Patrick Matthew, Charles Darwin and Alfred Wallace highlights their differences. In Matthew’s scheme, catastrophes initiate periods of radiation and speciation until a fully stocked environment enters into stasis. Catastrophes first need to exterminate competing species before the survivors can radiate into free niches and diversify into new species. In Darwin’s early theory, conditions of life, such as those prevailing under domestication, first need to increase the variability of a species before natural selection can transform it. In Darwin’s mature theory, competition replaces conditions as the main drive behind evolutionary change, and sympatric speciation becomes possible. Wallace’s theory differs from both Matthew’s and Darwin’s. Interspecific competition is not a brake halting transmutation (as in Matthew’s theory) nor is intraspecific competition a sufficient drive for it. Although each theory integrated natural selection with variability, competition and changed conditions in distinct ways, each allowed for species transmutation somehow. The result was similar (transmutation), but the mechanisms yielding that result (the integration of natural selection with variability, competition and change in conditions) differed significantly.

ARTICLE: ‘Great is Darwin and Bergson his poet’: Julian Huxley’s other evolutionary synthesis

A new article in the journal Annals of Science:

‘Great is Darwin and Bergson his poet’: Julian Huxley’s other evolutionary synthesis

Emily Herring

Abstract In 1912, Julian Huxley published his first book The Individual in the Animal Kingdom which he dedicated to the then world-famous French philosopher Henri Bergson. Historians have generally adopted one of two attitudes towards Huxley’s early encounter with Bergson. They either dismiss it entirely as unimportant or minimize it, deeming it a youthful indiscretion preceding Huxley’s full conversion to Fisherian Darwinism. Close biographical study and archive materials demonstrate, however, that neither position is tenable. The study of the Bergsonian elements in play in Julian Huxley’s early works fed into Huxley’s first ideas about progress in evolution and even his celebrated theories of bird courtship. Furthermore, the view that Huxley rejected Bergson in his later years needs to be revised. Although Huxley ended up claiming that Bergson’s theory of evolution had no explanatory power, he never repudiated the descriptive power of Bergson’s controversial notion of the élan vital. Even into the Modern Synthesis period, Huxley represented his own synthesis as drawing decisively on Bergson’s philosophy.

New article of interest in HOPOS: The Journal of the International Society for the History of Philosophy of Science:

Sir John F. W. Herschel and Charles Darwin: Nineteenth-Century Science and Its Methodology

Charles H. Pence

Abstract There are a bewildering variety of claims connecting Darwin to nineteenth-century philosophy of science—including to Herschel, Whewell, Lyell, German Romanticism, Comte, and others. I argue here that Herschel’s influence on Darwin is undeniable. The form of this influence, however, is often misunderstood. Darwin was not merely taking the concept of “analogy” from Herschel, nor was he combining such an analogy with a consilience as argued for by Whewell. On the contrary, Darwin’s Origin is written in precisely the manner that one would expect were Darwin attempting to model his work on the precepts found in Herschel’s Preliminary Discourse on Natural Science. While Hodge has worked out a careful interpretation of both Darwin and Herschel, drawing similar conclusions, his interpretation misreads Herschel’s use of the vera causa principle and the verification of hypotheses. The new reading that I present here resolves this trouble, combining Hodge’s careful treatment of the structure of the Origin with a more cautious understanding of Herschel’s philosophy of science. This interpretation lets us understand why Darwin laid out the Origin in the way that he did and also why Herschel so strongly disagreed, including in Herschel’s heretofore unanalyzed marginalia in his copy of Darwin’s book.

On Temminck’s tailless Ceylon Junglefowl, and how Darwin denied their existence

Hein van Grouw, Wim Dekkers, and Kees Rookmaaker

Abstract Ceylon Junglefowl was described in 1807 by the Dutch ornithologist
Coenraad Jacob Temminck. The specimens he examined were tailless (‘rumpless’)
and therefore he named them Gallus ecaudatus. In 1831 the French naturalist René
Primevère Lesson described a Ceylon Junglefowl with a tail as Gallus lafayetii (=
lafayetii), apparently unaware of Temminck’s ecaudatus. Subsequently, ecaudatus
and lafayetii were realised to be the same species, of which G. stanleyi and G.
lineatus are junior synonyms. However, Charles Darwin tried to disprove the
existence of wild tailless junglefowl on Ceylon in favour of his theory on the origin
of the domestic chicken.

Charles Darwin’s Theory of Moral Sentiments: What Darwin’s Ethics Really Owes to Adam Smith

Greg Priest

Abstract When we read the Origin, we cannot help but hear echoes of the Wealth of Nations. Darwin’s “economy of nature” features a “division of labour” that leads to complexity and productivity. We should not, however, analyze Darwin’s ethics through this lens. Darwin did not draw his economic ideas from Smith, nor did he base his ethics on an economic foundation. Darwin’s ethics rest on Smith’s notion from the Theory of Moral Sentiments of an innate human faculty of sympathy. Darwin gave this faculty an evolutionary interpretation and built on this foundation an ethics far removed from what is commonly supposed.



ARTICLE: The evolving spirit: morals and mutualism in Arabella Buckley’s evolutionary epic

The evolving spirit: morals and mutualism in Arabella Buckley’s evolutionary epic

Jordan Larsen

Abstract Contemporaries of Charles Darwin were divided on reconciling his theory of natural selection with religion and morality. Although Alfred Russel Wallace stands out as a spiritualist advocate of natural selection who rejected a natural origin of morality, the science popularizer and spiritualist Arabella Buckley (1840–1929) offers a more representative example of how theists, whether spiritualist or more orthodox in their religion, found reconciliation. Unlike Wallace, Buckley emphasized the lawful evolution of morality and of the soul, drawing from the theological tradition of traducianism. Significantly, Buckley argued for a mutualistic and deeply theistic interpretation of Darwinian evolution, particularly the evolution of morals, without sacrificing the uniformity of natural law. Though Buckley’s understanding of the evolutionary epic has been represented as emphasizing mutualism and spiritualist theology, here I demonstrate that her distinctive addition to the debate lies in her unifying theory of traducianism. In contrast to other authors, I argue that through Buckley we better understand Victorian spiritualism as more of a religion than an occult science. However, it was a conception of religion that, through her evolutionary traducianism, bridged science and spiritualism. This offers historians a more complex but satisfying image of the Victorian worldview after Darwin.
