With the careful use of the polywater episode in the history of chemistry as a case study, I will show that the distinction recently made in the philosophy of science between experimenting on an entity and manipulating that entity is best seen as a distinction between experimenting on, and experimenting with, that entity. The polywater case also reveals that Ian Hacking's 1983 manipulability criterion is not a necessary condition for realism, and that scientists can, and do, justifiably change their minds (...) as to the reality of theoretical entities.

Rolston (1988) argues that in order to act ethically in the environment, moral agents must assume that their actions are potentially harmful, and then strive to prove otherwise before implementing that action. In order to determine whether or not an action in the environment is harmful requires the tools of applied epistemology in order to act in accord with Rolston’s ethical prescription. This link between ethics and epistemology demands a closer look at the relationship between confirmation theory, particularly notions of (...) plausibility, in the philosophy of science and environmental ethics. Upon taking this look, I conclude that, at least logically, we are no better off assuming that actions are maximally risky (Rolston) than when we assume minimal risk. “Our vulnerability to error is greatest not from the things that we include in the model, but from the prophecies we leave out entirely.” Francis Bretherton “What is the main epistemic problem concerning science? I take it that it is the explication of how we compare and evaluate theories, as a basis either for theory acceptance or for practical action.” Bas van Fraassen “We face two kinds of ethical difficulties. One is where we know what ought to be done but not how to get the company to do it. The other is where we do not know what is right. We do not know the facts, or how to weigh the facts, especially statistical ones. We do not know the probabilities for development of future technologies. We do not know how to attach values to facts, or how to trade this good off against that one.” Holmes Rolston. (shrink)

Examines some of the potential and some of the problems inherent in using computerized simulations in science and science studies classes by applying lessons from the epistemology of science. While computer simulations are useful pedagogical tools, they are not experiments and thus are of only limited utility as substitutes for actual laboratories. Contains 20 references. (Author/PVD).

We develop and apply a multi-dimensional account of explanatory depth towards a comparative analysis of inflationary and bouncing paradigms in primordial cosmology. Our analysis builds on earlier work due to Azhar and Loeb (2021) that establishes initial conditions fine-tuning as a dimension of explanatory depth relevant to debates in contemporary cosmology. We propose dynamical fine-tuning and autonomy as two further dimensions of depth in the context of problems with instability and trans-Planckian modes that afflict bouncing and inflationary approaches respectively. In (...) the context of the latter issue, we argue that the recently formulated trans-Planckian censorship conjecture leads to a trade-off for inflationary models between dynamical fine-tuning and autonomy. We conclude with the suggestion that explanatory preference with regard to the different dimensions of depth is best understood in terms of differing attitudes towards heuristics for future model building.

An outline is given of the proof that the consistency of a κ⁺-Mahlo cardinal implies that of the statement that I[ω₂] does not include any stationary subsets of Cof(ω₁). An additional discussion of the techniques of this proof includes their use to obtain a model with no ω₂-Aronszajn tree and to add an ω₂-Souslin tree with finite conditions.

In this comment I discuss the role of an ethics case consultant in an institutional setting, in contrast to situations when an ethics consultant serves an individual client. In the former situation, I believe the case consultant should articulate ethical issues, options, and arguments, but not recommend a particular course of conduct. In the latter situation, the role of the ethics consultant can be defined and determined in negotiations with the client.

My interest is to examine the nature of mind in relation to value, for I suspect that the neglect by the psychologist of the true status of value has deterred his work in two respects: first, that it has prevented a genuine theory of mind's being arrived at, and secondly that it has prevented him in his clinical work from achieving for the individual the fuller expression of mind or self that makes for satisfaction or happiness.

In analyzing moral distress, perhaps greater attention should be given to the possible implicit sources of feelings of distress, as well as explicit sources.

This dissertation examines the strategy of justifying doctrinal beliefs by appealing to special revelation. Even if one thinks that belief in God is rationally warranted, it does not follow that one's distinctive religious doctrines are justified. Though theism may be justified, it remains an open question whether or not believers are entitled to believe, for example, that Jesus Christ is God Incarnate or that God is triune. Traditionally, religious believers have claimed that their doctrinal beliefs are justified because they have (...) been revealed by God. ;My assessment of this claim consists of three parts. First I examine the concept of special revelation and defend it against charges of incoherence. But if even it makes sense to say that God can reveal himself, the more philosophically interesting question concerns how we could know that he has in fact done so. Hence the second part of the dissertation assesses criteria for adjudicating revelation claims. Locke's claim that the veracity of revelation is vouchsafed through miracles is examined. I argue that it is preferable to understand our doctrinal beliefs as properly basic rather than attempt to authenticate revelation claims through appeals to miracles. Finally, in part three, I consider and respond to several objections against the claim that our doctrinal beliefs can be justified. The first objection says that the strategy of justifying doctrinal beliefs through appeals to special revelation is undermined by competing claims to revelation. The second criticism claims that appeals to special revelation fail to provide the degree of justification required to underwrite decisive assent to doctrinal beliefs. I argue that neither of these criticisms is effective. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:IntroductionWilliam J. ConnellOne of the more unusual works in the corpus of the Italian humanist Lorenzo Valla is the Oratio in principio sui studii, on the relation between Latin letters and the Christian faith. The speech was written and delivered in October 1455, toward the end of Valla’s life, as a lecture to inaugurate the academic year at the University of Rome where he had held the chair in (...) rhetoric since 1450. It was traditional at Rome to hold such an address each year not only to encourage the assembled students and faculty in their studies but also to thank the papacy for its support of the university, the Studium Urbis. For this reason Valla’s speech ends with customary words praising Pope Calixtus III for having increased the stipends of the lecturers in the university, even though, notwithstanding some remarkable kindnesses to Valla himself, Calixtus’s reputation was not that of a friend to scholarship. Valla’s Schoolyear Inaugural was not lengthy: it can only have lasted fifteen minutes. Nor is there indication that anyone was displeased with it. In fact, that is precisely what is oddest about the Inaugural, for throughout his career Valla had shown himself to be the sort of person who seized on such occasions to make polemical arguments. We read the speech—and it is possible that his audience also listened to it this way—expecting with each step that Valla will let fly a critical or unorthodox statement, but that never happens. 1Beginning with his earliest formal work, a comparison of Cicero and Quintilian written in 1428 and now lost, in which the humanist argued against Cicero on behalf of Quintilian, Valla seemed to delight in challenging established authorities. 2 His next important work, an attack on Bartolus of [End Page 1] Sassoferrato and the scholastic method of contemporary jurists, resulted in his forced departure from the University of Pavia. 3 A continuing combativeness is illustrated in subsequent writings, reaching an apogee in the work on the Donation. Even when Valla was developing another writer’s idea, he had a consistent way of pushing the argument to a daring extreme. This, as Riccardo Fubini argues below, is what Valla did in the De donatione, a work Fubini suggests relied more heavily on Nicholas of Cusa’s De concordantia catholica than hitherto realized, but written to promote an agenda far more radical than that of Cusanus. One of the surest indications of Valla’s brilliance as a polemicist is the fact that seventy years after his death humanists of the caliber of Agostino Steuco, the subject of Ronald K. Delph’s essay in this number, were still eager to take up cudgels against him.Valla paid a price for initiating so many disputes. In 1444, when he was called before the Inquisition in Naples after the attack on the Donation of Constantine, Valla was made to answer charges against not only that work, but also against the De vero bono for its Epicureanism, the De libero arbitrio for its determinism, the De professione religiosorum for its criticism of religious orders, and the Repastinatio totius dialectice et philosophie for various unorthodox statements, especially concerning the Trinity. This last work was the humanist’s most ambitious project, and he seems to have been aware of its explosive quality, since he alluded to a “peril to his life” should it be published. 4The 1455 Schoolyear Inaugural shows no trace of the risks that Valla took in his other writings, of his polemical temperament, or of his past disagreements with the Church. With style and vigor the speech argues that the Church deserves great thanks and praise for having ensured the survival [End Page 2] of Latin letters after the collapse of the Empire. This may seem a notable change of heart in the author who had written the oration On the Falsely Believed and Forged Donation of Constantin—a text which always seems to be lurking in the background of the Inaugural but which finds no explicit reference there. Given the proximity of Valla’s argument to the well-worn medieval theme of the translatio studii, his argument could hardly have been... (shrink)

The claim that glycogen contains protein was first made exactly 100 years ago and has been the subject of contention ever since. It has now been established that rabbit‐muscle glycogen contains a covalently bound protein of Mr 37,000, present in equimolar proportion to glycogen. The protein, named glycogenin, is joined to muscle glycogen via a novel linkage involving the hydroxyl group of tyrosine, a fact of possible significance in the light of insulin's message being transmitted by tyrosine phosphorylation. The protein (...) is seen as the biogenetic precursor of glycogen. Its existence suggests an additional mode of regulation of glycogen metabolism since the amount, turnover and cellular location of glycogenin will influence the corresponding parameters for glycogen. A protein “primer” is suggested for the biogenesis of storage polysaccharides in general. (shrink)

Scholars have remained undecided how much the British Idealists owe to Hegel, how much to Kant, and how much they may be credited with minting a new intellectual coinage of their own. By way of a detailed examination of T. H. Green’s metaphysics of free will and how it stands to both its Kantian and its Hegelian predecessors, this paper attempts to make some headway on that longstanding question of pedigree. It is argued that by translating previously naturalistic considerations about (...) free will into Kantian or atemporalist terms, Green makes some useful and important advances. But he still remains subject to the tension between libertarian and autonomous approaches to the issue. It might be wondered whether any theory could ever reconcile these two approaches, but it is argued that by filtering his Kantianism through a more Hegelian lens, Green manages somewhat to reduce the friction between these two perspectives and to get closer to his ideal of a unified theory of human free will.

The multi-dimensionality of the term ‘pragmatism’ is by now a well-known phenomenon. Much has been made of the Peircean pragmatic theory of meaning vis-a-vis the Jamesian pragmatic theory of truth. Sometimes the contrast is made too quickly. This results in the undervaluing of important similarities between the two thinkers.
