In The Logical Basis of Metaphysics, Dummett articulates and develops his “fundamental assumption” that the introduction rules for a logical constant determine its meaning. According to Dummett, logical laws in harmony with the introduction rules are justified, while logical laws not in harmony with the introduction rules are unjustified. This powerful picture enables Dummett to criticise certain aspects of our linguistic practice, such as the Law of Excluded Middle and the metaphysics of realism he believes it embodies, as not remaining (...) responsible to the meanings of the logical constants. Against Dummett's fundamental assumption, I bring to bear what in the Tractatus Wittgenstein describes as his “fundamental thought” that the logical constants do not represent. Properly understood, Wittgenstein's point is that since the logical constants may be eliminated from the propositional signs of a fully precise logical notation, the constants do not express meanings to which our use of expressions containing the constants is responsible. I then apply Wittgenstein's fundamental thought to Dummett's proof‐theoretic notation to show that far from determining the meanings of the logical constants, the introduction rules merely allow the constants to be edited from certain inferences, leaving Dummett with no semantic kernel with which to criticise other sentences or inferences featuring the constants. Thus, his picture of what it is to make clear the working of our language collapses. (shrink)

Using Martin Heidegger’s later philosophy as his springboard, Peter S. Dillard provides a radical reorientation of contemporary Christian theology. From Heidegger’s initially obscure texts concerning the holy, the gods, and the last god, Dillard extracts two possible non-metaphysical theologies: a theology of Streit and a theology of Gelassenheit. Both theologies promise to avoid metaphysical antinomies that traditionally hinder theology. After describing the strengths and weaknesses of each non-metaphysical theology, Dillard develops a Gelassenheit theology that ascribes a (...) definite phenomenology to the human encounter with divinity. This Gelassenheit theology also explains how this divinity can guide human action in concrete situations, remain deeply consonant with Christian beliefs in the Incarnation and the Trinity, and shed light on the Eucharist and Religious Vocations. Seminal ideas from Rudolf Otto and Ludwig Wittgenstein are applied at key points. Dillard concludes by encouraging others to develop an opposing Streit theology within the non-metaphysical, Heidegerrian framework he presents. (shrink)

Peter Geach offers a novel argument for the immaterialist conclusion that thinking is not a physical activity performed. Two crucial premises of Geach's argument are that thinking is a basic activity and that thinking is a non-clockable activity. It is argued that since Geach does not clarify in exactly what sense thinking is supposed to be a basic activity, the first premise of his argument has not been justified. It is then argued that the same Wittgensteinian considerations Geach takes (...) to show that there are no interior acts of meaning also show that there are no interior acts of thinking and hence no non-clockable interior acts of thinking. Thus the second premise of Geach's argument also has not been justified. Therefore, Geach's argument is unconvincing as it stands. (shrink)

Deflationism about truth is the claim that the concept of truth is completely explicated by the disquotational view of truth, where the latter is the specification of a device of semantic ascent that avoids the semantical paradoxes. Over the last twenty years, the plausibility of deflationism has been intensely debated by philosophers of language. A number of writers have argued that even though deflationism is a coherent view, it is false. Some maintain that this is because a complete account of (...) truth must reduce truth to purely physical concepts but that the disquotational view of truth provides no such reduction. Others hold that there are important uses of the truth predicate that cannot be assimilated to its use as a device of semantic ascent. (shrink)

I examine two arguments for the conclusion that thinking is not a physical process. James F. Ross argues that thinking is determinate in a manner that nopurely physical process can be. Peter Geach argues that thinking is a basic activity that, unlike basic physical processes, cannot be assigned a precise position in time. I present two objections to Ross’s argument. I then show that even if Geach’s argument avoids these objections, it is vulnerable to two other objections. I conclude (...) that neither argument establishes the immateriality of thinking.

Mass incarceration has become a flashpoint in a number of recent political and public policy debates. Consensus about how to balance the just punishment of offenders with the humanitarian goal of providing inmates with genuine opportunities for reconciliation, rehabilitation, and reintegration into society is lacking. Unfortunately, a dualistic “us-versus-them” narrative surrounding these issues has become entrenched, occluding fruitful dialogue and obscuring our ability to see the detrimental effects that our nation’s punitive turn has created. In this essay, we affirm the (...) insights of Wacquant, Clear, and other sociologists and introduce a theological narrative of solidarity and vulnerability that undermines the “us-versus-them” dichotomy and opens up a path for cultivating a “we” community.

The Franciscan thesis maintains that the primary motive of the Incarnation is to glorify the triune God in the person of Jesus Christ: though Christ atones for human sins, his coming isn't relative to our need for redemption but rather has an absolute primacy. The Franciscan thesis is sometimes associated with the counterfactual claim that Christ would have come even if humans hadn't sinned. In recent work on the Franciscan thesis, an attempt is made to prove the counterfactual claim on (...) the basis of a purely logical argument drawn from the writings of Bl. John Duns Scotus. After showing that this proof fails, I construct an axiological argument for the Franciscan thesis that disentangles it from unsubstantiated counterfactual claims while respecting the subtle interplay between natural and revealed theology. I then provide a metaphysical interpretation of the axiological argument that builds upon Scotist notions. Seen through this interpretive lens, Scotus's logical argument can be understood not as attempting to prove a counterfactual claim but as articulating Scotus's vision of what is required of any created order that is radically contingent on God's will yet perfectly glorifies its Creator. Thus understood, the Franciscan thesis challenges a powerful and influential picture in philosophical theology. (shrink)

Philosophical Investigations, EarlyView.

Drawing upon Saul Kripke’s discussion of rules, James F. Ross deduces the immateriality of thinking from the metaphysical determinacy of thinking and the metaphysical indeterminacy of any physical process. It has been objected that Ross does not establish the metaphysical indeterminacy of what function a physical process realizes, that Ross does not show the incoherence of a highly deflationary view of our talk about thinking, and that Ross opens up an unbridgeable gulf between sui generis thinking and behavior. Edward Feser (...) has recently defended Ross’s argument from these objections. The present paper explains why Ross’s argument remains vulnerable to all three objections. (shrink)

The Didascalicon of Hugh of St. Victor encourages the study of many disciplines in order for the soul to acquire knowledge that aids in the restoration of human nature. However, according to Hugh's epistemology much of the acquired knowledge depends upon sensory qualities internalized as images which distract the soul and cause it to degenerate from its original unity. This essay explores the tension between Hugh's educational optimism and Hugh's epistemological pessimism. After considering and rejecting two unsuccessful strategies the soul (...) might pursue for avoiding degeneration and distraction, we shall utilize Hugh's non-representational conception of cognition to develop a plausible intellectual strategy. We shall also build upon some of Hugh's remarks about music to sketch a model of self-knowledge as a kind of proportionality in the soul. (shrink)

In his article “What Do We Think With?” Peter Geach develops an argument for the non-materiality of thinking. Given that basic thinking activity is not clockable in physical time, whereas basic material or bodily activity is so clockable, it follows that basic thinking activity is non-material. Peter Dillard’s attack on this temporality proof takes “thoughts” in the proof to refer to non-occurrent states. The present note shows this reading to be mistaken and so rectifies a misunderstanding of (...) Geach’s argument. It takes no stand on the question of whether the argument succeeds. (shrink)

James Ross developed a simple and powerful argument for the immateriality of the intellect, an argument rooted in the Aristotelian-Scholastic tradition while drawing on ideas from analytic philosophers Saul Kripke, W. V. Quine, and Nelson Goodman. This paper provides a detailed exposition and defense of the argument, filling out aspects that Ross left sketchy. In particular, it elucidates the argument’s relationship to its Aristotelian-Scholastic and analytic antecedents, and to Kripke’s work especially; and it responds to objections or potential objections to (...) be found in the work of contemporary writers like Peter Dillard, Robert Pasnau, Brian Leftow, and Paul Churchland.

In this book, Peter Achinstein proposes and defends several objective concepts of evidence. He then explores the question of whether a scientific method, such as that represented in the four "Rules for the Study of Natural Philosophy" that Isaac Newton invoked in proving his law of gravity, can be employed in demonstrating how the proposed definitions of evidence are to be applied to real scientific cases.

Kant's Critique of Teleological Judgment is read as a reflection on philosophical methodological problems that arose through the constitution of an independent science of life - biology. This work presents an example of the interconnections between philosophy and the history of science.

New forms of information technology, such as email, webpages and groupware, are being rapidly adopted. Intended to improve efficiency and effectiveness, these technologies also have the potential to radically alter the way people communicate in organizations. The effects can be positive or negative. This paper explores how technology can encourage or discourage moral dialogue -- communication that is open, honest, and respectful of participants. It develops a framework that integrates formal properties of ideal moral discourse, based on Habermas' theory of (...) communicative action, with properties of informal communication that help sustain good moral conversations. Ten criteria distilled from these works form the basis of a template that can be used for assessing the positive and negative impacts of emerging information technologies on moral dialogue. (shrink)

In this major study, Peter Zarrow examines how textbooks published for the Chinese school system played a major role in shaping new social, cultural, and political trends, the ways in which schools conveyed traditional and 'new style' knowledge and how they sought to socialize students in a rapidly changing society in the first decades of the twentieth century. Focusing on language, morality and civics, history, and geography, Zarrow shows that textbooks were quick to reflect the changing views of Chinese (...) elites during this period. Officials and educators wanted children to understand the physical and human worlds, including the evolution of society, the institutions of the economy, and the foundations of the nation-state. Through textbooks, Chinese elites sought ways to link these abstractions to the concrete lives of children, conveying a variety of interpretations of enlightenment, citizenship, and nationalism that would shape a generation as modern citizens of a new China.

Peter Adamson offers an accessible, humorous tour through a period of eight hundred years when some of the most influential of all schools of thought were formed. He introduces us to Cynics and Skeptics, Epicureans and Stoics, emperors and slaves, and traces the development of early Christian philosophy and of ancient science. A major theme of the book is in fact the competition between pagan and Christian philosophy in this period, and the Jewish tradition appears in the shape of (...) Philo of Alexandria. Ancient science is also considered, with chapters on ancient medicine and the interaction between philosophy and astronomy. Considerable attention is paid also to the wider historical context, for instance by looking at the ascetic movement in Christianity and how it drew on ideas from Hellenic philosophy. From the counter-cultural witticisms of Diogenes the Cynic to the subtle skepticism of Sextus Empiricus, from the irreverent atheism of the Epicureans to the ambitious metaphysical speculation of Neoplatonism, from the ethical teachings of Marcus Aurelius to the political philosophy of Augustine, the book gathers together all aspects of later ancient thought in an accessible and entertaining way.

This collection of vivid and eloquent testimonies by environmentalists, eco-theologians, and native peoples illustrates a variety of responses to the same universal question: Where are we as a species heading on this planet? Contributors include Rick Bass, Wendell Berry, Annie Dillard. Gretel Ehrlich, Barry Lopez, Peter Mattheisen, Thomas Moore, Terry Tempest Williams, and others.

The metaphysics of relations is still in its infancy. We use the idea of truthmaking to gain purchase on this metaphysics. Assuming a modest supervenience conception of truthmaking, where true relational predications require multiply dependent truthmakers, these are indispensable relations. Though some such relations are required, none are needed for internal relatedness, nor for several other kinds of relational predication. Discerning the metaphysically basic kinds of relations is fraught with uncertainties, but must be tackled if progress is to be made.

The emergence of experimental philosophy was one of the most significant developments in the early modern period. However, it is often overlooked in modern scholarship, despite being associated with leading figures such as Francis Bacon, Robert Boyle, Isaac Newton, Jean Le Rond d'Alembert, David Hume and Christian Wolff. Ranging from the early Royal Society of London in the seventeenth century to the uptake of experimental philosophy in Paris and Berlin in the eighteenth, this book provides new terms of reference for (...) understanding early modern philosophy and science, and its eventual eclipse in the shadow of post-Kantian notions of empiricism and rationalism. Experimental Philosophy and the Origins of Empiricism is an integrated history of early modern experimental philosophy which challenges the rationalism and empiricism historiography that has dominated Anglophone history of philosophy for more than a century.
