Environmental ethics has almost exclusively been focused on multicellular organisms. However, because microorganisms form the base of the world’s food chains, allowing for the existence of all higher organisms, the complexities of the moral considerability of microorganisms deserve attention. Despite the impossible task of protecting individual microorganisms—the paradigmatic example of the limitations to a Schweitzerian “reverence for life”—microorganisms can be considered to have intrinsic value on the basis of conation, along with their enormous instrumental value. This intrinsic value even manifests (...) itself at the individual level, although in this case the ethic can only be regulative (an ethical principle). Biocentrism is the most appropriate ethical framework for microorganisms, and the most useful normative framework for implementing the preservation and conservation of microorganisms. This ethic has implications for how we deal with disease-causing microorganisms. (shrink)

In “The Book of the Crown (_Kitāb al-Iklīl_) of pseudo-Rhazes” Oliver Kahl and Henrietta Sharp Cockrell offer a facsimile edition, with annotated English translation and introductory study, of a unique and highly unusual medieval Arabic medical text.

Words like you, here, and tomorrow are different from other expressions in two ways. First, and by definition, they have different kinds of meanings, which are context-dependent in ways that the meanings of names and descriptions are not. Second, their meanings play a different kind of role in the interpretations of the utterances that contain them. For example, the meaning of you can be paraphrased by a description like "the addressee of the utterance." But an utterance of (1) doesn't say (...) the same thing as an utterance of (2). (shrink)

I assess a number of connected ideas about temporal experience that are introspectively plausible, but which I believe can be argued to be incorrect. These include the idea that temporal experiences are extended experiential processes, that they have an internal structure that in some way mirrors the structure of the apparent events they present, and the idea that time in experience is in some way represented by time itself. I explain how these ideas can be developed into more sharply defined (...) views, and then argue that these views are inconsistent with certain empirical facts about how time is represented in the brain. These facts instead support a kind of atomic view, on which temporal experiences are temporally unstructured atoms. (shrink)

Recent research has investigated whether people think of their moral beliefs as objectively true facts about the world, or as subjective preferences. The present research examines variability in the perceived objectivity of different moral beliefs, with respect both to the content of moral beliefs themselves (what they are about), and to the social representation of those moral beliefs (whether other individuals are thought to hold them). It also examines the possible consequences of perceiving a moral belief as objective. With respect (...) to the content of moral beliefs, we find that beliefs about the moral properties of negatively valenced acts are seen as reliably more objective than beliefs about the moral properties of positively valenced acts. With respect to the social representation of moral beliefs, we find that the degree of perceived consensus regarding a moral belief positively influences its perceived objectivity. The present experiments also demonstrate that holding a moral belief to be objective is associated with a more ‘closed’ response in the face of disagreement about it, and with more morally pejorative attributions towards a disagreeing other person.

Category theory and topos theory have been seen as providing a structuralist framework for mathematics autonomous vis-a-vis set theory. It is argued here that these theories require a background logic of relations and substantive assumptions addressing mathematical existence of categories themselves. We propose a synthesis of Bell's many-topoi view and modal-structuralism. Surprisingly, a combination of mereology and plural quantification suffices to describe hypothetical large domains, recovering the Grothendieck method of universes. Both topos theory and set theory can be carried out (...) relative to such domains; puzzles about ‘large categories’ and ‘proper classes’ are handled in a uniform way, by relativization, sustaining insights of Zermelo.

Three principal varieties of mathematical structuralism are compared: set-theoretic structuralism (‘STS’) using model theory, Shapiro's ante rem structuralism invoking sui generis universals (‘SGS’), and the author's modal-structuralism (‘MS’) invoking logical possibility. Several problems affecting STS are discussed concerning, e.g., multiplicity of universes. SGS overcomes these; but it faces further problems of its own, concerning, e.g., the very intelligibility of purely structural objects and relations. MS, in contrast, overcomes or avoids both sets of problems. Finally, it is argued that the modality (...) of MS or a close cousin appears at crucial junctures in both STS and SGS, so that the above outcome is not obviously tendentious. (shrink)

Artificial Intelligence in the form of different machine learning models is applied to Big Data as a way to turn data into valuable knowledge. The rhetoric is that ensuing predictions work well—with a high degree of autonomy and automation. We argue that we need to analyze the process of applying machine learning in depth and highlight at what point human knowledge production takes place in seemingly autonomous work. This article reintroduces classification theory as an important framework for understanding such seemingly (...) invisible knowledge production in the machine learning development and design processes. We suggest a framework for studying such classification closely tied to different steps in the work process and exemplify the framework on two experiments with machine learning applied to Facebook data from one of our labs. By doing so we demonstrate ways in which classification and potential discrimination take place in even seemingly unsupervised and autonomous models. Moving away from concepts of non-supervision and autonomy enable us to understand the underlying classificatory dispositifs in the work process and that this form of analysis constitutes a first step towards governance of artificial intelligence.

Hellman and Shapiro explore the development of the idea of the continuous, from the Aristotelian view that a true continuum cannot be composed of points to the now standard, entirely punctiform frameworks for analysis and geometry. They then investigate the underlying metaphysical issues concerning the nature of space or space-time.

The principle of sufficient reason threatens modal collapse. Some have suggested that by appealing to the indefinite extensibility of contingent truth, the threat is neutralized. This paper argues that this is not so. If the indefinite extensibility of contingent truth is developed in an analogous fashion to the most promising models of the indefinite extensibility of the concept set, plausible principles permit the derivation of modal collapse.

Some remarks on determination, physicalism, model theory, and logical truth.//An attempt to defend physicalism against objections that its bases are indeterminate.

Two kinds of theoretical framework for syntax are encountered in current linguistics. One emerged from the mathematization of proof theory, and is referred to here as generative-enumerative syntax (GES). A less explored alternative stems from the semantic side of logic, and is here called model-theoretic syntax (MTS). I sketch the outlines of each, and give a capsule summary of some mathematical results pertaining to the latter. I then briefly survey some diverse types of evidence suggesting that in some ways MTS (...) seems better suited to theorizing about the relevant linguistic phenomena. (shrink)

Traditional theories of associative learning have found no place for the possibility that the way in which events are perceived might change as a result of experience. Evidence for the reality of perceptual learning has come from those studied by learning theorists. The work reviewed in this book shows that learned changes in perceptual organization can in fact be demonstrated, even in experiments using procedures of the type on which associative theories have been based. These results come from procedures that (...) have been the focus of detailed theoretical and empirical analysis; and from this analysis emerges an outline of the mechanisms responsible. Some of these are themselves associative; others require the addition of nonassociative mechanisms to the traditional theory. The result is an extended version of associative theory which, it is argued, will be relevant not only to the experimental procedures discussed in this book but to the entire range of instances of perceptual learning.

It is possible to learn multiple layers of non-linear features by backpropagating error derivatives through a feedforward neural network. This is a very effective learning procedure when there is a huge amount of labeled training data, but for many learning tasks very few labeled examples are available. In an effort to overcome the need for labeled data, several different generative models were developed that learned interesting features by modeling the higher order statistical structure of a set of input vectors. One (...) of these generative models, the restricted Boltzmann machine (RBM), has no connections between its hidden units and this makes perceptual inference and learning much simpler. More significantly, after a layer of hidden features has been learned, the activities of these features can be used as training data for another RBM. By applying this idea recursively, it is possible to learn a deep hierarchy of progressively more complicated features without requiring any labeled data. This deep hierarchy can then be treated as a feedforward neural network which can be discriminatively fine-tuned using backpropagation. Using a stack of RBMs to initialize the weights of a feedforward neural network allows backpropagation to work effectively in much deeper networks and it leads to much better generalization. A stack of RBMs can also be used to initialize a deep Boltzmann machine that has many hidden layers. Combining this initialization method with a new method for fine-tuning the weights finally leads to the first efficient way of training Boltzmann machines with many hidden layers and millions of weights.

'Nobody reads Mill today,' wrote a reviewer in Time magazine a few years ago.! One could scarcely praise Mr Melvin Maddocks, who penned that remark, for his awareness of the present state of Mill studies, for of all nineteenth century philosophers who wrote in English, it is 1. S. Mill who remains the most read today. Yet it would not be so far from the truth to say that very few people pay much serious attention nowadays to Mill's writings about (...) logic and metaphysics (as distinct from those on ethical and social issues), despite the fact that Mill put enormous effort into their composition and through them exerted a considerable influen ce on the course of European philosophy for the rest of his century. But the only sections of A System of Logic (1843) and An Examination of Sir William Hamilton's Philosophy (1865) to which much reference is now made comprise only a small proportion of those very large books, and the prevailing assumption is that Mill's theories about logical and meta physical questions are, with few exceptions, of merely antiquarian in terest. Bertrand Russell once said that Mill's misfortune was to be born at the wrong time (Russell (1951), p. 2). It can certainly appear that Mill chose an inauspicious time to attempt a major work on logic. (shrink)

Several leading topics outstanding after John Earman's Bayes or Bust? are investigated further, with emphasis on the relevance of Bayesian explication in epistemology of science, despite certain limitations. (1) Dutch Book arguments are reformulated so that their independence from utility and preference in epistemic contexts is evident. (2) The Bayesian analysis of the Quine-Duhem problem is pursued; the phenomenon of a "protective belt" of auxiliary statements around reasonably successful theories is explicated. (3) The Bayesian approach to understanding the superiority of (...) variety of evidence is pursued; a recent challenge (by Wayne) is converted into a positive result on behalf of the Bayesian analysis, potentially with far-reaching consequences. (4) The condition for applying the merger-of-opinion results and the thesis of underdetermination of theories are compared, revealing significant limitations in applicability of the former. (5) Implications concerning "diachronic Dutch Book" arguments and "non-Bayesian shifts" are drawn, highlighting the incompleteness, but not incorrectness, of Bayesian analysis. (shrink)

This is the first of a pair of papers. It focuses on the development of the most notable phlogistic theories during the period 1766–1791, including the main experiments that their proponents proposed them to interpret. There was a rapid proliferation of late phlogistic theories, particularly from 1784, and the accounts of composition and important implications of the main theories are set out and their issues analysed. Each of them either reached impasses due to internal problems, or included features that made (...) them unacceptable even to other phlogistians. The expositions and analyses of these theories are given in terms of details that were in the literature at the time or otherwise potentially understandable by the participants given contemporary practice. Some relevant methodological aspects of the history of science are discussed, and the secondary literature is briefly surveyed. The second paper deals with the contemporary development of the new chemistry, and with theory comparison and theory choice in the same period. (shrink)

In 2005, Chinese President Hu Jintao instituted a “Harmonious Society” policy marking a new China’s approach toward development. This generated intense excitement among observers of Corporate Social Responsibility (CSR) who perceive an overlap in objectives between CSR and Harmonious Society and believe that Harmonious Society will lead to increased CSR engagement in China. However, there is little exploration of how Harmonious Society will contribute to increasing CSR engagement. This article seeks to explore whether Harmonious Society will meet this promise. It (...) does so by drawing up a list of actions that if taken by the government would increase the level of CSR in China and make Harmonious Society a relevant factor in the development of Chinese CSR. To do so, my article studies comparative literature on CSR development to develop a framework that divides causes of CSR in a country into environmental constraints and discretionary responses. Understanding what drives the development of CSR allows us to understand what measures the Chinese government can take to influence the level of CSR. Using this framework, my article suggests that Harmonious Society is unlikely to promote CSR in China’s growing private sector because policy measures that affect the “constraints” driving CSR are bounded by other political considerations.

A remarkable development in twentieth-century mathematics is smooth infinitesimal analysis ('SIA'), introducing nilsquare and nilpotent infinitesimals, recovering the bulk of scientifically applicable classical analysis ('CA') without resort to the method of limits. Formally, however, unlike Robinsonian 'nonstandard analysis', SIA conflicts with CA, deriving, e.g., 'not every quantity is either = 0 or not = 0.' Internally, consistency is maintained by using intuitionistic logic (without the law of excluded middle). This paper examines problems of interpretation resulting from this 'change of logic', (...) arguing that standard arguments based on 'smoothness' requirements are question-begging. Instead, it is suggested that recent philosophical work on the logic of vagueness is relevant, especially in the context of a Hilbertian structuralist view of mathematical axioms (as implicitly defining structures of interest). The relevance of both topos models for SIA and modal-structuralism as appled to this theory is clarified, sustaining this remarkable instance of mathematical pluralism. (shrink)

The primary objective of this article is to develop a framework for analyzing the ethical foundations and implications of shareholder wealth maximization (SWM). Distinctions between SWM and the more widely examined construct of profit maximization are identified, the most significant being the central role played in SWM by the market mechanism for pricing the corporation''s securities. It is argued that empirical tests concerned with evaluating the ethical implications of SWM will almost surely involve a joint hypothesis. A number of recent (...) empirical studies aimed at testing hypotheses with explicit ethical content are reviewed. (shrink)

I argue that the effectiveness of forgiveness in the healing of relationships is dependent on both the givers and recipients of forgiveness understanding that once it has been granted, forgiveness is not normally able to be retracted. When we forgive, we make a firm commitment not to return to our former state of moral resentment against the offender, replacing it by good-will. This commitment can be broken only where the forgiving party makes some significant cognitive adjustment to her appraisal of (...) either the offender or the offence, believing that her original forgiveness was granted in error. I reject the view that forgiveness can lapse or be withdrawn on the basis of a return of hurt or disappointed feelings, arguing that these do not amount to a restoration of the resentment that is extinguished when forgiveness is granted. I contend that a person who ‘forgives’ and later takes back that ‘forgiveness’ because certain negative feelings have returned either did not genuinely forgive in the first place or shows that she has not fully grasped the nature of forgiveness.

To what extent can constructive mathematics based on intuitionistc logic recover the mathematics needed for spacetime physics? Certain aspects of this important question are examined, both technical and philosophical. On the technical side, order, connectivity, and extremization properties of the continuum are reviewed, and attention is called to certain striking results concerning causal structure in General Relativity Theory, in particular the singularity theorems of Hawking and Penrose. As they stand, these results appear to elude constructivization. On the philosophical side, it (...) is argued that any mentalist-based radical constructivism suffers from a kind of neo-Kantian apriorism. It would be at best a lucky accident if objective spacetime structure mirrored mentalist mathematics. the latter would seem implicitly committed to a Leibnizian relationist view of spacetime, but is it doubtful if implementation of such a view would overcome the objection. As a result, an anti-realist view of physics seems forced on the radical constructivist. (shrink)

This paper examines how communities of naturalists in mid-nineteenth-century Britain were formed and solidified around the shared practices of public meetings, the publication and reading of periodicals, and the making and printing of images. By focusing on communities of naturalists and the sites of their communication, this article undermines the distinction between amateur and professional scientific practice. Building on the notion of imagined communities, this paper also shows that in some cases the editors and illustrators utilized imagery to construct a (...) specifically British naturalist community. Following three ‘amateur’ natural-history periodicals (Science Gossip,Midland Naturalistand theJournal of the Quekett Microscopical Club) the article demonstrates how the production and reproduction of natural history in the nineteenth century was contingent on community debate – and that this debate both was highly visual and moved across printed and geographical boundaries. This paper investigates images both for their purported success and for their ascribed value to natural history. Additionally, it considers the debates over their limitations and alleged failures of printing. Altogether, the article argues that investigating the communal practices of observation, writing, drawing and engraving allows for a better understanding of the shared practices of nineteenth-century natural history.

Beginning with Berkeley and Leibniz, philosophers have been puzzled by the close yet ambivalent association in Newton's ontology between God and absolute space and time. The 1962 publication of Newton's highly philosophical manuscript De Gravitatione has enriched our understanding of his subtle, sometimes cryptic, remarks on the divine underpinnings of space and time in better-known published works. But it has certainly not produced a scholarly consensus about Newton's exact position. In fact, three distinct lines of interpretation have emerged: Independence: space (...) and time are not essentially related to God. Causation: space and time are caused by God. Assimilation: space and time are attributes of God. This paper defends the third interpretation against the first two by drawing out the under-appreciated influence of Descartes' metaphysics on Newton's ‘physico-theology’. (shrink)

Descartes and William Harvey engaged in a polite dispute about the cause of the heart's motion. Descartes saw the heart's motion of passive; Harvey saw it as active. I criticize three prominent explanations for Descartes' opposition to Harvey's theory. I argue that Descartes found Harvey's model to be inconsistent with mind-body dualism and this was the reason he opposed it.
