Parts, classes and Parts of Classes: an anti-realist reading of Lewisian mereology

This study is in two parts. In the first part, various important principles of classical extensional mereology are derived on the basis of a nice axiomatization involving ‘part of’ and fusion. All results are proved here with full Fregean (and Gentzenian) rigor. They are chosen because they are needed for the second part. In the second part, this natural-deduction framework is used in order to regiment David Lewis’s justification of his Division Thesis, which features prominently in his combination of mereology with class theory. The Division Thesis plays a crucial role in Lewis’s informal argument for his Second Thesis in his book Parts of Classes. In order to present Lewis’s argument in rigorous detail, an elegant new principle is offered for the theory that combines class theory and mereology. The new principle is called the Canonical Decomposition Thesis. It secures Lewis’s Division Thesis on the strong construal required in order for his argument to go through. The exercise illustrates how careful one has to be when setting up the details of an adequate foundational theory of parts and classes. The main aim behind this investigation is to determine whether an anti-realist, inferentialist theorist of meaning has the resources to exhibit Lewis’s argument for his Second Thesis—which is central to his marriage of class theory with mereology—as a purely conceptual one. The formal analysis shows that Lewis’s argument, despite its striking appearance to the contrary, can be given in the constructive, relevant logic IR. This is the logic that the author has argued, elsewhere, to be the correct logic from an anti-realist point of view. The anti-realist is therefore in a position to regard Lewis’s argument as purely conceptual.     

Autonomy and Common Good: Interpreting Rousseau’s General Will

Rousseau’s project in his Social Contract was to construct a conception of human subjectivity and political institutions that would transcend what he saw to be the limits of liberal political theory of his time. I take this as a starting point to put forward an interpretation of his theory of the general will as a kind of social cognition that is able to preserve individual autonomy and freedom alongside concerns with the collective welfare of the community. But whereas many have seen Rousseau’s ideas as a prelude to communitarianism or authoritarianism, we should instead see his project as articulating an alternative model of moral-cognitivist reasoning. In order to provide a framework for this interpretation, I propose reading his conception of the general will through the theory of collective intentionality and social ontology. I end with a consideration of how this interpretation of the general will can provide a more satisfying understanding of political and practical rationality contemporary debates over republicanism and liberalism.     

Sen and Sensibility

Abstract

In The idea of justice (2009), Amartya Sen builds on his previous work on capabilities to develop a theory of comparative justice which he contrasts to the contractarian approach. The theory has two parts: the proper materials of justice (capabilities); and, a procedure for assessing those materials. The procedure that Sen advocates is one of open impartial deliberation opera-tionalised through Adam Smith’s impartial spectator, which he contends is superior to contractarian view operationalised by Rawls’ original position. In this paper we argue that Sen’s open impartiality is too open and defend a more bounded version as more workable regardless of the operationalising device used. Moreover, we demonstrate that Sen’s own arguments against the possibility of agreement, though aimed at the contractarian tradition, undermine his own attempts to generate a contentful account of justice by driving a wedge between the materials and procedures. Sen’s attempt to provide an alternative approach to political philosophy, we conclude, fails.     

Why we can still believe the error theory

The error theory is a metaethical theory that maintains that normative judgments are beliefs that ascribe normative properties, and that these properties do not exist. In a recent paper, Bart Streumer argues that it is impossible to fully believe the error theory. Surprisingly, he claims that this is not a problem for the error theorist: even if we can’t fully believe the error theory, the good news is that we can still come close to believing the error theory. In this paper I show that Streumer’s arguments fail. First, I lay out Streumer’s argument for why we can’t believe the error theory. Then, I argue against the unbelievability of the error theory. Finally, I show that Streumer’s positive proposal that we can come close to believing the error theory is actually undermined by his own argument for why we can’t believe the error theory.     

Bratman on identity over time and identification at a time

According to reductionists about agency, an agent’s bringing something about is reducible to states and events (such as desires and beliefs) involving the agent bringing something about. Many have worried that reductionism cannot accommodate robust forms of agency, such as self-determination. One common reductionist answer to this worry (which I call “identification reductionism”) contends that self-determining agents are identified with certain states and events, and so these states and events causing a decision counts as the agent’s self-determining the decision. In this paper, I discuss Michael Bratman’s well-known identification reductionist theory and his general strategy of grounding an agent’s identification at a time in the agent’s identity over time. I develop two constraints that an adequate identification reductionist theory must satisfy, argue that Bratman’s theory cannot satisfy both, and show that his general strategy for grounding an agent’s identification at a time in the agent’s identity over time is without merit.     

Narrative and Rhetorical Approaches to Problems of Education. Jerome Bruner and Kenneth Burke Revisited

Over the last few decades there has been a strong narrative turn within the humanities and social sciences in general and educational studies in particular. Especially Jerome Bruner’s theory of narrative as a specific ‘mode of knowing’ was very important for this growing body of work. To understand how the narrative mode works Bruner proposes to study narratives ‘at their far reach’—as an art form—and on several occasions he refers to the dramatistic pentad as an important method for ‘unpacking’ narratives. The pentad proposed by Bruner to study narratives was developed by the American philosopher and rhetorician Kenneth Burke and is embedded in his general linguistic theory of dramatism. From an educational perspective Bruner’s reference to the work of Burke has not been elaborated upon thus far. In this paper we aim to take Bruner’s suggestion at hand and explore how his educational theory of narrative as a mode of knowing can indeed be enriched by Kenneth Burke’s theory and method of dramatism. We claim that specifically the rhetorical framework that is developed by dramatism offers an important perspective about perspectives for education in a context that is increasingly confronted with a plurality of interpretive frameworks.     

From Normative Spheres to Normative Practices: New Prospects for Normative Theory after Habermas

Abstract

In this paper I argue against Jürgen Habermas’s theoretical dualism between ethics and morality. I do this by showing how his account of normativity is vitiated by an unnecessary superposition of a social-evolutionary and a theoretical-linguistic account of normativity, and that this brings about theoretical problems that in the end cannot be overcome. I also show that Rainer Forst’s attempt at salvaging Habermas’s distinction is equally doomed to failure, but that his attempt nevertheless invites new and more fruitful avenues for normative theory that are worth exploring. The conclusion of this paper is that traditional notions of ethics and morality can be preserved provided we heavily redefine their meanings and release them from some of the theoretical work they have been expected to accomplish, but that to complete this transition we also need to supersede Forst’s pluralization of normative contexts toward a theory of normative practices that in the end makes the distinction between ethics and morality workable but useless. I begin by first locating the debate about ethics and morality within the context of recent normative theory (§1), and proceed to examine the two main strategies through which Habermas has elaborated his idea of a sharp dualism between ethics and morality (§2). I then introduce a theoretical distinction between what I call a horizontal and a vertical integration of ethics and morality (§3) and contend that whilst only the horizontal is viable, Habermas decidedly prefers the idea of a vertical integration (§4). With this work done, I proceed to complete my critique of Habermas’s argument and show how, by recovering the pragmatist roots of his thought, an alternative solution based on a functionalist understanding of morality could be envisaged (§5). I then conclude by examining Rainer Forst’s attempt at salvaging Habermas’s account, and show that the failure of Forst’s attempts opens the way for new and more fruitful approaches to normative theory which are more likely to recover the pragmatist roots of Habermas’s thought (§6).     

Vier Philosophen über semantische Paradoxien

In his treatise on sophisms, the medieval logician and philosopher J. Buridan expounded a theory on what we have come to call semantic paradoxes. His theory has not yet been fully understood. The present paper aims at showing that Barwise’s and Etchemendy’s considerations on paradoxes (founded upon Aczel’s non-well-founded sets) provide the framework for an improved understanding. Barwise’s and Etchemendy’s account is contrasted with Kripke’s. Finally, a recent analysis of Buridan’s position by Epstein is criticized     

Paving the Way? Penalty and Atonement in Thomas Aquinas's Soteriology

This article explores the soteriology of Thomas Aquinas. In particular, it considers recent debates over whether Thomas altered Anselm's satisfaction theory in a way which opened the door to the later theory of penal substitution. The article argues that Thomas did indeed alter Anselm's atonement theory in this way insofar as he incorporates punishment within his concept of satisfaction; however, it further contends that his use of ‘placation’ or ‘appeasement’ language does not contribute to such an alteration.     

Misers or lovers? How a reflection on Christian mysticism caused a shift in Jacques Lacan’s object theory

In his sixth seminar, Desire and Its Interpretation (1956–1957), Lacan patiently elaborates his theory of the ‘phantasm’ ($?a), in which the object of desire (object small a) is ascribed a constitutive role in the architecture of the libidinal subject. In that seminar, Lacan shows his fascination for an aphorism of the twentieth century Christian mystic Simone Weil in her assertion: “to ascertain exactly what the miser whose treasure was stolen lost: thus we would learn much.” This is why, in his theory, Lacan conceptualizes the object of desire as the unconsumed treasure—and, in that sense, the “nothing”—on which the miser’s desire is focused. But the more Lacan develops his new object theory, the more he realizes how close it is to Christian mysticism in locating the ultimate object of desire in God, in a sevenfold “nothing” (to quote the famous last step in the ascent of the Mount Carmel as described by John of the Cross). An analysis of Shakespeare’s Hamlet allows Lacan to escape the Christian logic and to rearticulate the object of desire in an ‘unchristian’ tragic grammar. When he replaces the miser by the lover as paradigm of the subject’s relation to its object of desire, he substitutes a strictly Greek kind of love—eros, not agape—for the miser’s relationship to his treasure. Even when, in the late Lacan, “love” becomes a proper concept, its structure remains deeply “tragic.”     

The metaphysics of human freedom: from Kant’s transcendental idealism to Schelling’s Freiheitsschrift

Schelling’s 1809 Freiheitsschrift (Philosophical Investigations into the Essence of Human Freedom), perhaps his most widely read work, presents considerable difficulties of understanding. In this paper, I offer an interpretation of the work in relation to Kant. My focus is on the relation in each case of their theory of human freedom to their general metaphysics, a relation which both regard as essential. The argument of the paper is in sum that Schelling may be viewed as addressing and resolving a problem which faces Kant’s theory of freedom and transcendental idealism, deriving from the challenge posed by Spinozism. One major innovation in Schelling’s theory of human freedom is his claim that it presupposes the reality of evil. I argue that Schelling’s thesis concerning evil also provides a key to the new and highly original metaphysics of the Freiheitsschrift. The relation of Schelling’s theory of freedom to his general metaphysics is therefore complex, for it goes in two directions: the metaphysics are not simply presupposed by the theory of freedom but are also in part derived from it. These new metaphysics also, I argue, allow Schelling to resolve a problem which his own earlier Spinozistic system had left unresolved.     

Boghossian’s Inference Argument against Content Externalism Reversed*

I deal here with one of Boghossian’s arguments against content externalism, related to our inferential rationality (to use his term). According to his reasoning, the apriority of our logical abilities is inconsistent with certain externalist assumptions. Nevertheless, the problem constitutes an important challenge for any theory of content, not just for externalism. Furthermore, when we examine what internalists may propose to solve the problem, we see that externalists have at their disposal a more promising repertoire of possible replies than internalists. In that sense, insofar as Boghossian’s scenario is relevant to the debate externalism/internalism, it can be seen (against Boghossian’s original intention) as providing additional evidence for content externalism.     

Assessing theories,Bayes style

The problem addressed in this paper is “the main epistemic problem concerning science”, viz. “the explication of how we compare and evaluate theories [...] in the light of the available evidence” (van Fraassen, BC, 1983, Theory comparison and relevant Evidence. In J. Earman (Ed.), Testing scientific theories (pp. 27–42). Minneapolis: University of Minnesota Press). Sections 1– 3 contain the general plausibility-informativeness theory of theory assessment. In a nutshell, the message is (1) that there are two values a theory should exhibit: truth and informativeness—measured respectively by a truth indicator and a strength indicator; (2) that these two values are conflicting in the sense that the former is a decreasing and the latter an increasing function of the logical strength of the theory to be assessed; and (3) that in assessing a given theory by the available data one should weigh between these two conflicting aspects in such a way that any surplus in informativeness succeeds, if the shortfall in plausibility is small enough. Particular accounts of this general theory arise by inserting particular strength indicators and truth indicators. In Section 4 the theory is spelt out for the Bayesian paradigm of subjective probabilities. It is then compared to incremental Bayesian confirmation theory. Section 4 closes by asking whether it is likely to be lovely. Section 5 discusses a few problems of confirmation theory in the light of the present approach. In particular, it is briefly indicated how the present account gives rise to a new analysis of Hempel’s conditions of adequacy for any relation of confirmation (Hempel, CG, 1945, Studies in the logic of comfirmation. Mind, 54, 1–26, 97–121.), differing from the one Carnap gave in § 87 of his Logical foundations of probability (1962, Chicago: University of Chicago Press). Section 6 adresses the question of justification any theory of theory assessment has to face: why should one stick to theories given high assessment values rather than to any other theories? The answer given by the Bayesian version of the account presented in section 4 is that one should accept theories given high assessment values, because, in the medium run, theory assessment almost surely takes one to the most informative among all true theories when presented separating data. The concluding section 7 continues the comparison between the present account and incremental Bayesian confirmation theory.     

Metameric Whiteness and Absence of Causal Factors

Olaf Müller presents a supposedly empirically equivalent theory to Newtonian optics, which in his view is therefore threatened by underdetermination. This threat could even be expanded to modern physics, since this branch of physics is partly based on Newton’s theory. In this paper, I will show that Müller’s alternative theory contains an ill-defined concept, viz. the definition of whiteness as the absence of optical causal factors. This results from a fundamental property of whiteness: for every source of white light there exist metameric sources. I further argue that this cannot be reconciled by borrowing other concepts from modern physics, as is, I will show, tacitly presupposed in Müller’s argument. As a consequence, his alternative theory is not empirically equivalent to Newtonian optics and his argument in favour of underdetermination fails.     

Gerald Edelman’s Project: How Gerald Edelman’s Theory of Consciousness Completes Darwin’s Theory of Evolution and Provides a Basis for a Brain-Based Psychoanalytic Perspective

In this article we consider Nobel Prize Winner Gerald Edelman’s remarkable contribution to the understanding of human evolution, and our own application of Edelman’s theory to a brain-based psychoanalytic perspective we have devised. Edelman’s paradigm setting out his theory of the evolution of mind, brain, and consciousness concerns not only mankind’s evolution over all of time, but also the evolution of each and every individual over and within his single lifetime. Edelman contends that human beings, as individuals, and not only as the taxonomic category from which they sprang, have a separate and distinct evolutionary history of their own, and it is especially from within Edelman’s theoretical assumptions about the evolution of the individual per se that our own psychoanalytic understanding of theory and practice derives.     

Gödel And The Intuition Of Concepts

Gödel has argued that we can cultivate the intuition or ‘perception’ of abstractconcepts in mathematics and logic. Gödel's ideas about the intuition of conceptsare not incidental to his later philosophical thinking but are related to many otherthemes in his work, and especially to his reflections on the incompleteness theorems.I describe how some of Gödel's claims about the intuition of abstract concepts are related to other themes in his philosophy of mathematics. In most of this paper, however,I focus on a central question that has been raised in the literature on Gödel: what kind of account could be given of the intuition of abstract concepts? I sketch an answer to this question that uses some ideas of a philosopher to whom Gödel also turned in this connection: Edmund Husserl. The answer depends on how we understand the conscious directedness toward ‘objects’ and the meaning of the term ‘abstract’ in the context of a theory of the intentionality of cognition.     

Gods and giants: Cudworth’s platonic metaphysics and his ancient theology

ABSTRACT

The Cambridge Platonists are modern thinkers and the context of seventeenth-century Cambridge science is an inalienable and decisive part of their thought. Cudworth’s interest in ancient theology, however, seems to conflict with the progressive aspect of his philosophy. The problem of the nature, however, of this ‘Platonism’ is unavoidable. Even in his complex and recondite ancient theology Cudworth is motivated by philosophical considerations, and his legacy among philosophers in the eighteenth and nineteenth centuries should not be overlooked. In particular we will draw on the scholarship of the German Egyptologist Jan Assmann in order to reassess the significance of Cudworth’s theory of religion for later philosophical developments.     

Duns Scotus’ univocity: applied to the debate on phenomenological theology

Scotus’ theory of univocity is described: his exact definition of univocity and his view of transcendental concepts that are ‘simply simple’. These concepts are said to be univocally applied to God and creatures. Next, we describe Scotus’ views on univocity in ‘being’ and the precise meaning of the infinite and finite ‘mode’ of being. Finally, we apply these results to work of Heidegger and Marion. It appears that they had an insufficient grasp of the intricacies of Scotus’ theory of univocity and that Marion’s religious phenomenology could have benefitted from these scotistic tools.
