To the medieval thinker, man was the center of creation and all of nature existed purely for his benefit. The shift from the philosophy of the Middle Ages to the modern view of humanity's less central place in the universe ranks as the greatest revolution in the history of Western thought, and this classic in the philosophy of science describes and analyzes how the profound change occurred. A fascinating analysis of the works of Copernicus, Kepler, Galileo, Descartes, Hobbes, Gilbert, Boyle, (...) and Newton, it not only establishes the reasons for the triumph of the modern perspective but also accounts for certain limitations that characterize contemporary scientific thought.

In his recently published book Animals and African Ethics, Kai Horsthemke makes two important and related claims. The first is that most African metaphysical, religious, and ethical positions and perspectives on animals are anthropocentric. Second, he states that if there are one or more principles of duties regarding other animals derivable from these positions and perspectives, they are at best “indirect duties.” In this article, I critically engage with these claims in the context of the ontological beliefs and ethical standpoints (...) that flow from anthropocentrism, biocentrism, and ecocentrism. I argue that the African metaphysical worldview and African practices on animals are not anthropocentric. The nub of my argument is that a closer examination of African practices on animals and one dominant African metaphysical worldview—one that Horsthemke engages with in the book—presents us a different conclusion, one that suggests that the worldview and practices are conceivably biocentric or ecocentric rather than anthropocentric.

Many authors have posited an “object file” system, which underlies perceptual selection and tracking of objects. Several have proposed that this system internalizes principles specifying what counts as an object and relies on them during tracking. Here I consider a popular view on which the object file system is tuned to entities that satisfy principles of three-dimensionality, cohesion, and boundedness. I argue that the evidence gathered in support of this view is consistent with a more permissive view on which object (...) files select and track according to well-known perceptual organization criteria. Further evidence supplies positive support for the permissive view. (shrink)

The position that I defend and argue for in this paper is that we ought to or are obligated to Africanise the philosophy curriculum in universities in Africa. This obligation is grounded on the overarching consideration not to wrong Africans by committing testimonial and hermeneutical injustices against them, and where committing these forms of epistemic injustice prevents us from enhancing the autonomy of Africans and maximising or promoting utility. I take the issues that I discuss and the argument that I (...) provide for this position to be important, particularly in our times. This is so in the context of present and broader debates and discussions, not just in respect of decolonisation in education, and the Africanisation of institutional cultures and practices in schools or tertiary institutions, but also regarding curriculum transformation and development, in general, and diversification of the philosophy curriculum, in particular.

A variety of modal logics based on the relevant logic R are presented. Models are given for each of these logics and completeness is shown. It is also shown that each of these logics admits Ackermann's rule γ and as a corollary of this it is proved that each logic is a conservative extension of its counterpart based on classical logic, hence we call them “classically complete”.

Notes and Discussions Calvin and Hobbes, or, Hobbes as an Orthodox Christian Three years ago, in the proceedings of an Italian conference on Hobbes and Spinoza, I published an article arguing that Hobbes was at best a deist, and most likely an atheist? In a recent book on Hobbes, A. P. Martinich devoted an appendix to criticizing that article, as part of his case that Hobbes is not merely a theist, but an orthodox Christian, and specifically, that he had "a (...) strong commitment" to the Calvinist branch of the Church of England.' It has been suggested that I respond to Martinich's rebuttal, and I think I should. Martinich's work is arguably the best available book of its kind.3 Pursuing the issues this book raises may help us to see why it is worth our while to be curious about the differences between the English text of Leviathan, first published in 165 x, and the Latin text of that work, first published in 1668. This is a topic generally ignored in English-language discussions of Hobbes and one in which I have a special interest.4 The great virtue of Martinich's book is that he is very precise about what his thesis See '"I Durst Not Write So Boldly' or, How to Read Hobbes' Theological-Political Treatise," in Hobbes e Spinoza, Atti del Convegno Internazionale, Urbino, i4-~ 7 ottobre, 1988 , ed. by Daniela Bostrenghi, intro, by Emilia Giancotti . By 'deist' I understand someone who believes in a personal God, but rejects divine.. (shrink)

I argue that there is no fallacy of argument from authority. I first show the weakness of the case for there being such a fallacy: text-book presentations are confused, alleged examples are not genuinely exemplary, reasons given for its alleged fallaciousness are not convincing. Then I analyse arguing from authority as a complex speech act. Rejecting the popular but unjustified category of the "part-time fallacy", I show that bad arguments which appeal to authority are defective through breach of some felicity (...) condition on argument as a speech act, not through employing a bad principle of inference.

Kindness and its kindred concepts, compassion and empathy, are strongly valued in healthcare. But at the same time, health systems all too often treat people unfairly and cause harm. Is it possible that kindness actually contributes to these unkind outcomes? Here, I argue that, despite its attractive qualities, kindness can pose and perpetuate systemic problems in healthcare. By being discretionary, it can interfere with justice and non-maleficence. It can be problematic for autonomy too. Using the principalist lens allows us to (...) visualise kindness more clearly and to dissect out its key qualities. Ideally, kindness should be not just beneficent but also respectful of the person, fair and non-maleficent. I use examples to illustrate the adverse impacts when kindness runs short on each. Finally, I propose that we can improve on this, by diversifying our approach to inclusion. Outgroups should be more included, as a way to mitigate discrimination wrought by discretionary kindness. But we can do better. Ingroup health professionals too often sit ‘above the fray’. They should also be more included, but now as research subjects, so we can understand together how they benefit from discretionary kindness and deftly make it work for them and theirs. (shrink)

This paper presents a probabilist paraconsistent theory of belief revision. This theory is based on a very general theory of probability, that fits with a wide range of classical and nonclassical logics. The theory incorporates a version of Jeffrey conditionalisation as its method of updating. A Dutch book argument is given, and the theory is applied to the problem of choosing a logical system.

The specific characteristics of mathematical argumentation all depend on the centrality that writing has in the practice of mathematics, but blindness to this fact is near universal. What follows concerns just one of those characteristics, justification by proof. There is a prevalent view that long proofs pose a problem for the thesis that mathematical knowledge is justified by proof. I argue that there is no such problem: in fact, virtually all the justifications of mathematical knowledge are ‘long proofs’, but because (...) these real justifications are distributed in the written archive of mathematics, proofs remain surveyable, hence good.

This book is a comparative study which covers a number of major jurisdictions, viz., Australia, Belgium, Canada, England and Wales, France, Germany, Italy, Japan, Spain, Sweden, The Netherlands and the USA. A separate chapter deals with developments in the context of the European Union. The study is based on a questionnaire of the IBA Section on Business Law Subcommittee on the Structure and Ethics of Business Law. Part one of each country report covers the basic rules applying to the domestic (...) legal profession, such as the method of qualifying as a lawyer, the extent to which legal services are reserved to lawyers, and the ethical rules which apply to matters such as advertising, fees, correspondence, etc. The second part sets out what rules the jurisdiction in question imposes on its own lawyers when they are involved outside the jurisdiction. The third part deals with the rules which apply to a foreign lawyer practising within the jurisdiction. The last part deals with the various kinds of international associations to which lawyers may be party, such as alliances, office-sharing and multi-national and multi-disciplinary partnerships. In a final chapter the editor draws some conclusions on the current situation and on where international practice is heading. A number of useful appendices have been added, which set out the most important texts including the IBA International Code of Ethics. (shrink)

The fregean theory of meaning says how the meaningful parts of a meaningful expression contribute to that expression's sense and reference. But frege overlooks the fact that logical expressions play dual roles. The contributions of sentential connectives, For example, Are well described for contexts in which they connect sentences, But not for larger quantificational contexts. An obvious modification of the theory which might fill the abyss is considered, And it is maintained that it produces two difficulties: a replication of frege's (...) concept 'horse' troubles and an infinite proliferation of logical vocabulary. The seriousness of these difficulties is briefly discussed. (shrink)

The manuscript of Andocides' speechOn the Mysteriescontains a series of documentary inserts culminating in the decrees of Patroclides, Tisamenus and Demophantus. These decrees seem to fit their historical context and they are presented at length, with at least a few of the formalities that we would expect to find in the official record. Modern commentators have relied upon them as substantially genuine, allowing for the usual errors in transmission, but now their authenticity is contested. A close reading by Mirko Canevaro (...) and Edward Harris rejects all three of these documents as products of feckless ‘forgery’. Alan Sommerstein responded with a strong defence of Demophantus' decree, and Mogens Hansen has recently defended Patroclides' decree and Tisamenus' as well. On many points the defenders are persuasive, but the sceptics make a good case, and so it seems reasonable to reconsider how these documents took shape. (shrink)

The ¿scrutiny of all the laws¿ that Andocides invokes in his defence On the Mysteries is usually interpreted as a recodification with the aim of barring prosecution for the crimes of civil conflict. This article advances four theses against that traditional reading: (1) In Andocides¿ argument the Scrutiny was designed for a more practicable purpose, not to pardon crimes unpunished but to quash any further action against former atimoi, those penalized under the old regime but restored to rights in 403. (...) In context, coming close upon the summary of Patrocleides¿ decree, ¿all the laws¿ means all laws affecting atimoi. (2) The other evidence from inscriptions and literary testimony, for the Athenian Amnesty and similar agreements, supports this reading: the oath that closed the covenants, mê mnêsikakein, functions as a rule of estoppel or ¿no reprise¿; it was not in itself a pledge of ¿political forgiveness¿. In regard to the Scrutiny, as in Patrocleides¿ decree, the oath means that old penalties, now cancelled, can never again be enforced. (3) The Scrutiny itself was a reauthorization of the old laws for summary arrest and other standard remedies against atimoi who trespass or violate their restrictions. As a corollary to this re-enactment, the statute of limitations was introduced, ¿to apply the laws from Eucleides¿: the rules punishing the disfranchised cannot be used against those whose liabilities were incurred before 403. (4) Teisamenus¿ decree for new legislation was prior to this revision; it is not the decree that Andocides read to the court as a document of the Scrutiny. An ancient editor simply inserted the wrong document. Teisamenus envisioned no alteration of the ¿Solonian Code¿; the decree for Scrutiny was an unforeseen but necessary correction. These measures were successive reforms sorting out the new hierarchy of rules, a process whose complexity is attested in Diocles¿ law. (shrink)

Bargaining and distribution of benefits accruing from social cooperation are central topics in contractarian accounts of morality or distributive justice in general and David Gauthier’s Morals by Agreement in particular. In this paper, I raise some problems for MbA both with regards to bargaining over the benefits of social cooperation and the distribution of such benefits. The worries I raise piggyback on a couple of Jan Narveson’s earlier queries of some of the topics in MbA: those of ‘questionable foundation’ and (...) redundancy. However, I go beyond the substance of these queries by arguing that they raise fundamental worries about the correctness of the description of the elements of the bargaining situation, and the role and significance of agreement in MbA.
