Note on Howard Sankey's "Induction and Natural Kinds".

The normative nature of scientific rationality is sometimes accounted for by the thesis that having theories which meet the criteria we apply is valuable to us in itself rather than as a means to an end. But given the experiential input to our beliefs and their practical role, it is apparent that we must evaluate the criteria to be used as rational means of pursuing predictive success. So we must seek a practical justification, in spite of the threat of circularity. (...) There is hope of achieving this via an exploration of options which may show that there is no reasonable alternative to the principles we use. (shrink)

Note on Howard Sankey's "Induction and Natural Kinds".

The main theme is that theorizing serves empirical prediction. This is used as the core of a counter to contemporary anti-realist arguments. Different versions of the thesis that data underdetermines theory are identified and it is shown that none which are acceptable differentiates between theory selection and prediction. Criteria sufficient for the former are included amongst those necessary for the latter; and obviously go beyond mere compatibility with data.Special attention is given to causal process theories. It is argued that the (...) only empirically equivalent alternatives which can be constructed to any theory of this kind must be parasitic on that theory; so a choice for the original theory can not be avoided. Once this is established, a positive case for taking a realist position can be developed. (shrink)

This paper is an attempt at a vindication of induction. The point of departure is that induction requires a justification and that the only kind of justification possible is a vindication. However traditional vindications of induction have rested on unjustified assumptions about the aim of induction. This vindication takes the end pursued in induction simply to be correct prediction. It is argued that induction is the only reasonable way of pursuing this end because induction is the only objective method of (...) predicting. While objectivity is not a necessary condition for successful predicting, it is a sufficient condition for the possession of a property that is, in turn, a necessary condition for correct predicting; and further there could be no reason to expect any non-objective method to possess this necessary condition for success. Induction is the only objective method of predicting for it alone uses facts which must be identified by any predicting method based on rules; and it alone uses these facts according to a relationship that must hold between facts and any meaningful empirical statement. Any alternative to induction must assume that the factual regularities that have been detected will alter in the future and the way they are expected to alter must be arbitrary. It is further claimed that this vindication is proof against the criticisms that have been advanced against practicalist justifications of induction. (shrink)

Reichenbach held that all scientific inference reduces, via probability calculus, to induction, and he held that induction can be justified. He sees scientific knowledge in a practical context and insists that any rational assessment of actions requires a justification of induction. Gaps remain in his justifying argument; for we can not hope to prove that induction will succeed if success is possible. However, there are good prospects for completing a justification of essentially the kind he sought by showing that while (...) induction may succeed, no alternative is a rational way of trying.Reichenbach's claim that probability calculus, especially via Bayes' Theorem, can help to exhibit the structure of inference to theories is a valuable insight. However, his thesis that the weighting of all hypotheses rests only on frequency data is too restrictive, especially given his scientific realism. Other empirical factors are relevant. Any satisfactory account of scientific inference must be deeply indebted to Reichenbach's foundation work. (shrink)

This essay is based on a lecture delivered at the 2002 IRAS Star Island conference, the theme of which was “Is Nature Enough? The Thirst for Transcendence.” I had been asked to represent the position of those who would answer No to the question. I thought it would stimulate discussion if I presented my side of the debate in a somewhat provocative manner rather than use a more ponderous approach that would argue each point in a meticulous and protracted fashion. (...) Here I lay out a theological position that finds naturalism wanting in three ways: in terms of human spiritual needs, in terms of the mind's need for deep explanation, and in terms of the perennial human search for truth. Again, the style of presentation, like that of the original lecture, prohibits the kind of philosophical development that an adequate answer to each of the issues requires. The purpose is that of evoking discussion on a most important question. (shrink)

Frank Jackson's criticisms have helped me recognize some of the weaknesses in my proposed vindication of induction. The core of the argument I offered was that induction is the only method of predicting which is based in a nonarbitrary way on the facts. I still believe that this is so and that because of this property induction is the only reasonable way of predicting. However I now recognize defects in the argument by which I attempted to establish that the uniqueness (...) of this property to induction constitutes its justification. (shrink)

The paper proposes an explication of causation in terms of laws and their explanatory systematization. A basic notion is "nomic dependence". The definition given by David Lewis is suitable for deterministic laws, and a general definition drawing on Wesley Salmon's statistical-relevance model of explanation is proposed. A test is offered for establishing that one chain of nomically dependent events is more direct than another that ends with the same event by considering the relationship between the two chains when an explanation (...) in terms of more basic laws is sought. The chain to an event can be defined as causal if it is the most direct nomically linked chain leading up to that event. (shrink)

Pierre Teilhard de Chardin challenged theology to reach for an understanding of God that would take into account the reality of evolution. Paul Tillich's notion of New Being goes a long way toward meeting this challenge, and a theology of evolution can gain a great deal from Tillich's religious thought. But Teilhard would still wonder whether the philosophical notion of being, even when qualified by the adjective new, is itself adequate to contextualize evolution theologically. To Teilhard a theology attuned to (...) a post–Darwinian world requires nothing less than a revolution in our understanding of what is ultimately real. It is doubtful that Tillich's rather classical theological system is radical enough to accommodate this requirement. For Teilhard, on the other hand, a metaphysics grounded in the biblical vision, wherein God is understood as the future on which the world rests as its sole support, can provide a more suitable setting for evolutionary theology.

J. J. Katz in “The Problem of Induction and its Solution” argues that not only a validation but also a vindication of induction is impossible. In the course of his argument a number of interesting issues arise about what is actually required for a satisfactory vindication. The aim of those who have sought to provide a vindication for induction has been to show that it is the most satisfactory means for forming expectations about the future; they have accepted the impossibility (...) of showing that induction must, or will probably, lead to true predictions. Feigl gives a general characterisation of vindication as an “argument concerning means with respect to ends” and contrasts it to validation which is a justification of a knowledge claim by establishing it as true or probably true. We cannot validate the rules of induction but we can give a vindication of the adoption of these rules. Katz accepts Feigl's distinction in general terms but proposes some modifications to meet certain defects which he believes to be present in the latter's account. Katz distinguishes two senses of vindication, an “expediency vindication” which “establishes a justificandum as a suitable means,” while a “preferability vindication” “establishes the justificandum as the preferable means for achieving the end.” An expediency vindication shows that the proposed means is a sufficient condition for achieving the end in view, but it need not establish this means as necessary to achieve this end. A preferability vindication will establish the means as necessary to achieve this end in the best way. He then proceeds as follows: “an argument which demonstrates that a justificandum is a necessary condition—but only a necessary condition—for achieving the relevant end is not a real vindication.” He holds that the vindication of a certain means must show at least that it will achieve the end sought, and preferably that it is the best way of achieving this end.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Unlike some recent authors, Hilary Putnam recognizes that we can not avoid inquiring about the normative force of the principles that guide scientific reasoning. His answer is in terms of values. In presenting his case for “Internal Realism”, he argues that values are presupposed in statements of fact (1981, pp. 128-134). The central thesis in his argument is that truth is not a correspondence with an “unconceptualized reality” and that “the claim that science seeks to discover the truth can mean (...) no more than that science seeks to construct a world picture which, in the ideal limit, satisfies certain criteria of rational acceptability” (p. 130). We adopt these criteria because having a theory which conforms to them is valuable to us; it is part of human flourishing (pp. 133-134). (shrink)

In A Third Window Robert Ulanowicz exposes the explanatory weaknesses of both classical and statistical methods in scientific inquiry. His book, however, does much more than that. While being completely grounded in empirical science, it also outlines a worldview, or a metaphysics, that renders intelligible the fact of chance and emergent novelty. Ulanowicz establishes his position by comparing his third window onto nature with two others conventional scientific approaches. The purpose of this essay is to point out the value of (...) Ulanowicz’s approach for improving the quality of conversation between science and theology. (shrink)

Robert Russell's theological work has been a helpful stimulus to the task of understanding the meaning of divine action and providence in the age of science. He relates God's direct action "fundamentally" to the hidden domain of quantum events, and his theology of nature deserves careful attention. It is questionable, however, whether the term fundamental as applied to quantum events by physical science may be taken over by theology without more careful qualification than Russell offers.

Evolutionary biology contributes much to our present understanding of life, and it promises also to deepen our understanding of human intelligence, ethics, and even religion. For some scientific thinkers, however, Darwin's science seems so impressive that it now supplants theology altogether by providing the ultimate explanation of all manifestations of life, not only biologically but also metaphysically. By focusing on human intelligence as an emergent aspect of nature this essay examines the question of whether theology can still have an explanatory (...) role to play alongside biology in attempts to understand mind.

In his challenging article, Steneck (1997) criticized the creation of the Institutional Animal Care and Use Committee (IACUC) system established by the 1985 amendments to the Animal Welfare Act. He saw the IACUC review and approval of biomedical and behavioral research with animals as an unnecessary "reassignment" of duties from existing animal care programs to IACUC committees. He argued that the committees are unable to do the work expected of them for basically three reasons: (a) the membership lacks the expertise (...) in matters relevant to animal research and care, (b) there exists an inherent and disabling conflict of interest, and (c) the committee's operational base of authority is alien to academic culture and violates essential aspects of academic freedom. In addition, he found that the system is burdensome, requiring enormous expenditures of time and money that inappropriately diverts resources away from the business of scientific discovery. We dispute several aspects of Steneck's historical account and the coherence of his proposals. We believe his proposals, if followed, would be a step back into a failed past. (shrink)

This paper evaluates the recent trend to renounce the similarity approach to counterfactuals in favor of the older metalinguistic theory. I try to show, first, that the metalinguistic theory cannot work in anything like its present form (the form described by many in the last decade who claim to be able to solve Goodman''s old problem of cotenability). This is so, I argue, because the metalinguistic theory requires laws of nature of a sort that we (apparently) do not have: current (...) physical theory cannot underwrite the metalinguistic theory. Second, I draw from the first point a motivation for the similarity approach, a motivation based on theoretical considerations apart from the standard ones of pretheoretical intuition. (shrink)

Has Darwinian science made natural theology obsolete, as many Christian scholars now believe? In this article, the author assumes that natural theology does not take place in a religious vacuum but instead borrows its sense of god from this or that specific faith tradition. Its task is not to arrive at an understanding of the divine mystery different from that of systematic or doctrinal theology. As the author shall argue here, however, the empirical grounding essential to natural theology must be (...) considerably more comprehensive and more profound than that provided by the natural sciences, mainly because the latter usually leave out any mention of the most striking of all natural phenomena – the human mind and its mysterious operations.The author maintains that an exclusively Darwinian narrative cannot fully explain why your mind is restless for truth or why you should trust your mind. The point of natural theology is to ask whether nature as a whole is intelligible apart from the reality of God. The author’s point is that an empirical survey of nature that restricts itself to following the modern scientific method’s habitual exclusion of thought from its survey of nature cannot succeed in making nature intelligible.Contribution: This article argues that evolutionary explanations alone are not enough to account for all that is happening in human understanding and knowing. In the light of evolutionary biology, we must note that even human intelligence, which formerly seemed to elevate our species to a perch above nature, now appears to be an unexceptional product of chance, deep time and natural selection. ‘Thought’, the name we may give to the most splendid of all evolutionary outcomes, is taken to be a product of impersonal natural selection and so also are our moral instincts.

Although Michael Polanyi's model of science and his construal of the nature of the real are usually thought to be congenial to religion and although Polanyi himself says that “the stage on which we thus resume our full intellectual powers is borrowed from the Christian scheme of Fall and Redemption” (Polanyi 1958, 324), theologians have given little attention to the model of God he presents. The metaphysical and theological vision unfolded in part 4 of Personal Knowledge is a thoughtful alternative (...) to materialist versions of neo‐Darwinism and provides a platform for revisiting four long‐standing controversies at the interface of science and religion: whether life and mind can be completely specified in terms of physical analysis, whether nature can be adequately understood without appeal to final causes, whether natural selection adequately explains life's diverse forms, and whether knowledge can be fully objectified. Through an exploration of Polanyi's contribution to these discussions, we undertake to show not only that his treatment of God as a cosmic field is strikingly original but also that in reinstating activity as a metaphysical category, he reconstructs our understanding of our creaturely hope and calling.

Evolutionary biology has considerably altered our understanding of life, and it now promises to enhance our understanding of human existence by providing new insights into the meaning of intelligence, ethical aspiration and religious life. For some scientific thinkers, especially those who espouse a physicalist worldview, Darwin’s science seems so impressive that it now replaces theology by providing the deepest available explanation of all manifestations of life, including human intelligence. By focusing on human intelligence this essay asks whether a theological perspective (...) on the universe can still have an illuminating role to play alongside of biology in contemporary attempts to understand human intelligence.

Hegel on Logic and Religion is a collection of previously published essays which have been arranged under three general headings: “Logic,” “Logic Applied,” and “Christianity.” It proposes a Hegelian response to Lessing’s well-known rejection of the claim of Christian apologetics to provide an adequate “rational theology.” Such apologetics held that the reliability of the historical testimony to Christ’s miracles and resurrection is cogent evidence to warrant claims for his divinity. Lessing concedes the assertions of historical veracity but denies their cogency (...) for drawing rational conclusions about divinity. There is, he argues an “ugly broad ditch” separating the necessary truths of reason from the contingent truths of history. Lessing’s attack, moreover, did more than strike at the heart of traditional Christian apologetics. It also rendered a central project of the German Enlightenment problematic. Thinkers such as Mendelssohn held that metaphysics could provide a new rational basis for the claims of historical religion. So—according to Lessing—whether one approached historical faith from the perspective of a metaphysical system, or began on the opposite site side and used history as evidence for conceptions of divinity, one was brought to a halt before the “ugly, broad ditch.”.
