In his paper “William Whewell on the Consilience of Inductions” Professor Laudan has suggested that Whewell’s use of “consilience of inductions” is not the same as mine in my paper of that title. Suppose we have a theory T which entails three empirical laws L1, L2, L3. L1 is supposed already confirmed by direct evidence of its instances, but we have as yet no direct evidence for L2 or for L3. Then Laudan distinguishes two problems: Whewell’s problem: T is suggested (...) to explain L1 and is supported by L1; how much is our confidence in T increased if it also predicts L2, and L2 is subsequently directly confirmed? My problem: T is suggested to explain L1 and is supported by L1; T also entails L3; how much is our confidence that L3 will turn out a correct prediction increased by the fact that T entails it?

The section on the Argument from Design in collections of readings in the philosophy of religion usually begins with an expository selection drawn from Archdeacon William Paley’s Natural Theology, and follows with a critical selection drawn from David Hume’s Dialogues Concerning Natural Religion. Only from the footnotes does the student learn that Hume’s Dialogues was published over twenty years before Paley’s Natural Theology. Probably the student will feel that Hume’s devastating critique of the Argument must strike every reasonable person with (...) equal force, and so he will conclude that Paley must have been an archetypal intellectual conservative—a man whose ideas were dead and fossilized long before he put pen to paper. In fact, historically, the very opposite was the case. Although few could deny Hume’s towering intellect—“God’s greatest gift to the infidel” one fellow Scot grudgingly called him—Hume failed entirely to break the hold that the Argument from Design had on people’s imaginations. As many of us feel about Descartes’s arguments from illusion, people “knew” that somehow there must be a flaw in Hume’s argumentation, for, in the words of the anatomist Richard Owen, organic characters like the hand, the foot, and the eye, bear “irrefragable evidence of creative foresight.” Far from being outdated before it appeared, Paley’s book, in which he drew lucidly upon the most recent findings in natural science, rapidly became the standard work on the Argument from Design. It was, for instance, considered essential reading in any young man’s university education. (shrink)

Summary The object of this study is to analyse certain aspects of the debate between David Brewster and William Whewell concerning the probability of extra-terrestrial life, in order to illustrate the nature, constitution and condition of natural theology in the decades immediately preceding the publication in 1859 of Charles Darwin's Origin of species. The argument is directed against a stylised picture of natural theology which has been drawn from a backward projection of the Darwinian antithesis between natural selection and certain (...) forms of the design argument. Contrary to the popular image of natural theology as an essentially static, autonomous and monolithic set of presuppositions about the existence of design in nature, the paper underlines the existence of a fundamental divergence of strategies within natural theology, a divergence that, in the case of Brewster and Whewell, can be correlated with the religious cultures to which they most closely belonged. The fact that, in the plurality of worlds debate, their respective positions became mutually exclusive suggests that the fragmented and disordered state of natural theology, only too apparent before the Darwinian impact, was occasioned as much by the ulterior problem of rationalising the excessive space of the astronomers and the excessive time of the geologists as it was by any principle of the uniformity of nature in the biological sphere. The argument is substantiated with particular reference to the breakdown in communication as Brewster and Whewell developed conflicting strategies to expose the ?development hypothesis? that had appeared in Vestiges. Their altercation also reveals a certain conflict of status concerning the conclusions of astronomy and geology which, in turn, suggests that tensions between the physical and life sciences were not peculiar to the period following the publication of Darwin's theory.

Most contributions to Whewell scholarship have tended to stress the idealistic, antiempirical temper of Whewell’s philosophy. Thus, the only two monograph-length studies on Whewell, Blanché’s Le Rationalisme de Whewell and Marcucci’s L’ ‘Idealismo’ Scientifico di William Whewell, are, as their titles suggest, concerned primarily with Whewell’s departures from classical British empiricism. Particularly in his famous dispute with Mill, it has proved tempting to parody Whewell’s position in the debate by treating it as a straightforward encounter between an arch-empiricist and an (...) arch-rationalist. There is, however, a danger that an emphasis on the necessitarian and a priori elements in Whewell’s philosophy may well obscure the unmistakable empirical emphasis in Whewell’s theory of science. I think it is time to begin to redress the balance, by focusing attention on the significant ‘empiricist’ strains in Whewell’s philosophy of science. One of the most important of those strains is connected with the operation which Whewell calls ‘the consilience of inductions’. (shrink)

Professor Marcucci's book on Whewell [6] is a comprehensive expository treatment of Whewell's philosophy of science. The work contains chapters on Whewell's theory of ideas, the fundamental principles of his philosophy of science, his views on mathematics and mechanics, and on his philosophy of induction and philosophy of discovery. In addition there is a chapter on the English reception of Whewell's thought. Professor Marcucci's notes are rich, both in references to Whewell's many critics and to nearly all of the extant (...) literature on Whewell. Indeed, no full study of Whewell has as yet appeared that makes better or more extensive use of all the relevant literature on Whewell. (shrink)

The paper attempts to elucidate and evaluate William Whewell's notion of a "consilience of inductions." In section I Whewellian consilience is defined and shown to differ considerably from what latter-day writers talk about when they use the term. In section II a primary analysis of consilience is shown to yield two types of consilient processes, one in which one of the lower-level laws undergoes a conceptual change (the case aptly discussed in Butts [1977]), and one in which the explanatory theory (...) undergoes conceptual "stretching." In section III both consilient cases are compared to the non-consilient case in reference to L. J. Cohen's method of relevant variables. In section IV we examine the test procedures of the theory in all three cases, and it is shown that in the event of genuine consilience (consilience of the second type) a theory acquires extraordinarily high support. In the final section something is said of the short-comings of standard Bayesian confirmation theories that are highlighted by Whewellian consilience. (shrink)
