When Charles Darwin published his theory in 1859 the biological community gave very different receptions to the idea of evolution and to the theory of natural selection. Evolution was accepted as widely and rapidly as natural selection was rejected. Most biologists were ready to accept that evolution had occurred, but not that natural selection was its cause. They preferred other explanations of evolution, such as theories of big directed variation, or admitted that they did not know its cause. Darwin himself (...) never maintained that natural selection was the sole cause of evolution. He thought of it as one among several causes, and did not specify how much evolution had occurred by the natural selection of fortuitous variations, and how much by other factors such as the inherited effects of use and disuse. However, Darwin did maintain that natural selection was in principle capable of explaining all the observed properties of organisms. He did not think that there were some characteristics that were particularly likely to have evolved by natural selection, and other kinds that were not. Against this, many of this critics thought that there were characteristics that natural selection was particularly powerless to explain. Thus it could not account for characteristics that were detrimental, or those that seemed useless (such as species differences), or those that were of too little importance for natural selection to have favoured them. There were also characteristics of such complexity that it was unimaginable that natural selection could have built them up in tiny stages from fortuitous, undirected variants. The present essay will be concerned with just one, the last mentioned, of these kinds of characteristics. (shrink)

This paper examines the undervalued role of Herbert Spencer in Sidgwick's thinking. Sidgwick recognized Spencer's utilitarianism, but criticized him on the ground that he tried to deduce utilitarianism from evolutionary theory. In analysing these criticisms, this paper concludes that Spencer's deductive methodology was in fact closer to Sidgwick's empiricist position than Sidgwick realized. The real source of Sidgwick's unhappiness withSpencer lies with the substance of Spencer's utilitarianism, namely its espousal of indefeasible moral rights.

How is moral thinking, ethics, related to evolutionary theorizing? There are two approaches, epitomized by Charles Darwin who works under the metaphor of the world as a machine, and by Herbert Spencer who works under the metaphor of the world as an organism. Although the author prefers the first approach, the aim of this paper is to give a disinterested account of both approaches.

: The study of perfection, progress and evolution is a central theme in the history of ideas. This thesis explores this theme seen and understood as part of a discourse in the new fields of anthropology, sociology and psychology in the nineteenth century. A particular focus is on the stance taken by philosophers, scientists and writers in the discussion of theories of human physical and mental evolution, as well as on their views concerning the nature of social progress and historical (...) change. The wisdom and feasibility of improving the human species is discussed alongside an analysis of new methods of investigating and measuring physical and mental attributes of the human organism.The instruments used to assess the development of mind, body and society are described, and are viewed as part of an increased emphasis on the use of technology as an integral part of modern life, and as a means toward the ordered gathering of information in social-scientific practice. An international perspective is taken by observing the way in which ideas about the physical and mental development of humankind was discussed in light and consequence of English and European scientific exploration in the Southern Hemisphere. Further, an evaluation is made of the manner of the spread of new thought in the social sciences from the intellectual and cultural 'centre' of England and Europe to the Anglo-European community located at the 'periphery' in Australia in the late nineteenth century. In particular the educative role played by the non-professional enthusiast as a pivotal conduit for the dissemination of these ideas is highlighted and linked back to a significant tradition of amateur scholarship as a central phenomenon in the study of the history of ideas.

In 1864 nine eminent scientists, who had long been intimate friends, formed a dining club in order to prevent their drifting apart due to their various duties, and in order to further the cause of science. The club, which acquired the title of “X Club”, held monthly meetings from October to June, and was extremely active for two decades, but then gradually lessened in vitality. It served as a highly significant fraternity of scientists, and the regular communication which it afforded (...) helped the members to marshall their efforts on behalf of science against what they felt to be the obstructionist activities and ideas of conservative scientists, certain theologians, and non-scientific society figures.

The idea of evolution functions today as a myth as well as a scientific theory. This use distorts it in some surprising ways. In particular, predictions of the predestined future development of superhumans (Omega Man) are sometimes treated by scientists as if they were an established part of the theory of evolution. Since they rest on the endless–escalator model of evolution, incompatible with Darwinian methods and not separately argued for, they have no standing at all. This phenomenon, and others like (...) it, seem to indicate spiritual needs which are being ignored and thus finding illicit satisfaction. The position is dangerous and needs more attention.

‘Our’ included not only Hooker and Huxley but their fellow-members of the X-Club. ‘Our time’ had been the 1870s and early 1880s. For a five-year period from November 1873 to November 1878 Hooker had been President of the Society, Huxley one of the Secretaries, and fellow X-Club member, William Spottiswoode, the Treasurer. Hooker was followed in the Presidency by Spottiswoode, and on Spottiswoode's death in 1883 Huxley was elected President. During this period other X-Club members—Edward Frankland, John Tyndall, George Busk, (...) Sir John Lubbock, and Thomas Hirst—were ordinary members of the Council of the Society. As the Table below (p. 60) shows, there were at least three members of the X-Club on the Council of the Royal Society from November 1870 until November 1882. On eight occasions in this period there were four or more X-Club members on the Council. ‘Our time’ came to an end in 1885 when ill-health forced Huxley's retirement after only two years in the Presidency, and G. G. Stokes at last became President. (shrink)
