Wittgenstein on Scepticism and Nonsense

In the Tractatus Wittgenstein wrote: “Skepticism is not irrefutable, but obviously nonsensical when it tries to raise doubts where no questions can be asked.” In this paper I show how Wittgenstein developed this insight in On Certainty. My principal aim is to show that this is a logical insight, that it is bound up with the distinction between saying and showing, and that one misses the point of On Certainty if one reads it, as some commentators have, in epistemological terms. Throughout all of this I pay special attention to why Wittgenstein thought that skepticism is nonsensical, and what it might mean to say that philosophy is a logical investigation.     

On Kant's Conception of Inner Sense: Self‐Affection by the Understanding

Among the extensive literature on the first Critique, very few commentators offer a thorough analysis of Kant's conception of inner sense. This is quite surprising since the notion is central to Kant's theoretical philosophy, and it is very difficult to provide a consistent interpretation of this notion. In this paper, I first summarize Kant's claims about inner sense in the Transcendental Aesthetic and show why existing interpretations have been unable to dissolve the tensions arising from the conjunction of these claims. Secondly, I present my own reconstruction of Kant's model of inner sense, relying essentially on Kantian considerations found in the B‐version of the Transcendental Deduction. My main idea is that inner sense, for Kant, is a passive faculty that gets affected by the understanding performing its figurative synthesis on material given in outer sense. In the remainder of the paper, I highlight a few consequences of my interpretation and outline ways to deal with some objections.     

Educating pain

Abstract

In times in which we ask ourselves how political cruelty and torments can be forgotten, Nietzsche’s pleadoyer for pain to serve the purpose of education, surprises. What might sound like a mere provocation, rather lies at the heart of the Nietzschean philosophy. As is pointed out, Nietzsche’s contention that pain is the most powerful aid to mnemonics, originates from his philosophy of pain as the main condition of all forms of creation. The title “educating (bilden) pain” expresses Nietzsche’s advocacy of an education towards pain as the dynamo of creation. In this paper I explore how Nietzsche’s notion of pain is linked to two concepts of Bildung. In the first part I investigate the relation between pain and “Bildung” in the sense of “creation”, and in the second part I link this to the relation between pain and “Bildung” in the sense of “education”. By these means, I try to answer the question: how far can pain, which is seen as the condition of creation, be linked to conditions of education.     

Conceptualism and the (Supposed) Non-Transitivity of Colour Indiscriminability

In this paper, I argue that those who accept the conceptualist view in the philosophy of perception should reject the traditional view that colour indiscriminability is non-transitive. I start by outlining the general strategy that conceptualists have adopted in response to the familiar ‘fineness of grain’ objection, and I show why a commitment to what I call the indiscriminability claim seems to form a natural part of this strategy. I then show how together, the indiscriminability claim and the non-transitivity claim –the claim that colour indiscriminability is non-transitive –entail a further, suspicious-looking claim that I call the problematic claim. My argument then splits into two parts. In the first part, I show why the conceptualist does indeed need to reject the problematic claim. Given that this claim is jointly entailed by the indiscriminability claim and the non-transitivity claim, the conceptualist is then left with a straight choice: reject the indiscriminability claim, or reject the non-transitivity claim. In the second part, I then explain why the conceptualist should choose the latter option.     

The Motivation for “Toward an African Moral Theory”

Abstract

Here I introduce the symposium issue of the South African Journal of Philosophy that is devoted to critically analysing my article “Toward an African Moral Theory.” In that article, I use the techniques of analytic moral philosophy to articulate and defend a moral theory that both is grounded on the values of peoples living in sub-Saharan Africa and differs from what is influential in contemporary Western ethics. Here, I not only present a précis of the article, but also provide a sketch of why I have undertaken the sort of project begun there, what I hope it will help to achieve, and how the contributors to the symposium principally question it.     

Religion without Metaphysics1

In this paper I will argue for a conception of religion that does not presuppose metaphysics in the traditional sense of the word. In a trivial sense we always have ideas of what is given and are all realists, living by our realist intuitions. But the philosophically crucial question is what conclusions can be reasonably drawn from this. In Part I, I will argue against metaphysical realism in general. In Part II, I will argue against its materialist challenge by showing in what sense it too can be conceived of as an example of metaphysical realism. In Part III, I will show why there is no point in defending or in arguing against religion en bloc. Finally in Part IV, I will argue for a conception of religion without metaphysics in the traditional sense by taking account of the existential function religion actually has in human life.     

Kant's Criticism of Common Moral Rational Cognition

There is a consensus that Kant's aim in the Groundwork is to clarify, systematize and vindicate the common conception of morality. Philosophical theory hence serves a restorative function. It can strengthen agents' motivation, protect against self‐deception and correct misunderstandings produced by uncritical moral theory. In this paper, I argue that Kant also corrects the common perspective and that Kant's Groundwork shows in which senses the common perspective, even considered apart from its propensity to self‐deception and without being influenced by misleading theory, is deficient. Critical practical philosophy needs to set right agents about the stringency of some of their duties, and agents need to be made aware that they have certain other duties. I discuss how Kant corrects the common agent's notion of the stringency of the duty to not make false promises and how Kant corrects the common agent's notion of duties to self. I finally discuss how his critical practical philosophy can become popular and achieve the correction of the common perspective. I stress the role of education informed by philosophical theory for this and contrast it with so called ‘popular philosophy’.     

Neo-pragmatic intentionality and enactive perception: a compromise between extended and enactive minds

The general idea of enactive perception is that actual and potential embodied activities determine perceptual experience. Some extended mind theorists, such as Andy Clark, refute this claim despite their general emphasis on the importance of the body. I propose a compromise to this opposition. The extended mind thesis is allegedly a consequence of our commonsense understanding of the mind. Furthermore, extended mind theorists assume the existence of non-human minds. I explore the precise nature of the commonsense understanding of the mind, which accepts both extended minds and non-human minds. In the area of philosophy of mind, there are two theories of intentionality based on such commonsense understandings: neo-behaviorism defended, e.g., by Daniel Dennett, and neo-pragmatism advocated, e.g., by Robert Brandom. Neither account is in full agreement with how people ordinarily use their commonsense understanding. Neo-pragmatism, however, can overcome its problem—its inability to explain why people routinely find intentionality in non-humans—by incorporating the phenomenological suggestion that interactional bodily skills determine how we perceive others’ intentionality. I call this integrative position embodied neo-pragmatism. I conclude that the extended view of the mind makes sense, without denying the existence of non-human minds, only by assuming embodied neo-pragmatism and hence the general idea of enactive perception.     

Philosophy,and teaching (as) transformation

Abstract

This paper explores a paradox constitutive of transformation discourse in South Africa: the transformation of a fragmented society presupposes the existence of a collective Will; but the creation of a collective will can only result from a process of transformation. While politicians and higher education administrators debate how best to conceive and implement transformation, committed lecturers have to find ways of teaching the reality of that ideal full knowing that it is in part through teaching that this ideal is achieved. The 2010 HE Summit (HES) called on all universities to ‘purposefully address the issue of social cohesion as part of their transformation agenda’ (2010: 20). In this paper the learning encounter is posited as the paradoxical site where the assumption of a national subjectivity (‘social cohesion’) becomes reproductive of that subjectivity. This suggests a degree of ‘bootstrapping’ in the sense that the learning encounter necessarily posits a historical Subject that is paradoxically both cause and effect of transformation. This is an interpretative paper that reflects on what it means to practise philosophy in such a context. Taking Readings’s The University in Ruins (1996) as point of departure it starts with a general, historical reflection on the telos of higher education which is then contextualised with reference to the post-colonial university. Towards the end I briefly consider aspects of my own philosophy teaching praxis in light of that theoretical frame. I engage the ‘bootstrapping’ paradox by suggesting that teaching (as) transformation comprises four moments: making students aware of 1) the fact that they belong to specific socio-epistemic communities; 2) that this sense of community is an historical construct which 3) implies limitations on the possibility of knowing and being that can 4) only be questioned through an encounter with what is other to that socio-epistemic community. In short, it is argued that in a university context the possibility of ‘social cohesion’ is first and foremost a confrontation with the conditions for the possibility of inter-subjective learning.     

C. I. Lewis,Kant, and the reflective method of philosophy

ABSTRACT

If it seems unquestionable that C. I. Lewis is a Kantian in important respects, it is more difficult to determine what, if anything, is original about his Kantianism. For it might be argued that Lewis’ Kantianism simply reflects an approach to the a priori which was very common in the first half of the twentieth century, namely, the effort to make the a priori relative. In this paper, I will argue that Lewis’ Kantianism does present original features. The latter can be detected by focusing on Lewis’ account of the method of philosophy in the first chapter of Mind and the World Order. In that context, Lewis argues that the method of philosophy should be reflective and critical. It will be my contention that this understanding of philosophy involves a therapeutic perspective, which bears important resemblances to Kant’s account of transcendental reflection in the Amphiboly of the Critique of Pure Reason. I will illustrate how this therapeutic application of reflection works in Lewis’ metaphysics. In this context, reflection can correct errors of reasoning that occur when we are operating within a particular conceptual scheme and use the criteria of reality that are appropriate in another.     

On Wittgenstein's and Carnap's Conceptions of the Dissolution of Philosophical Problems,and against a Therapeutic Mix: How to Solve the Paradox of the Tractatus

In this article, I distinguish Wittgenstein's conception of the dissolution of philosophical problems from that of Carnap. I argue that the conception of dissolution assumed by the therapeutic interpretations of the Tractatus is more similar to Carnap's than to Wittgenstein's for whom dissolution involves spelling out an alternative in the context of which relevant problems do not arise. To clarify this I outline a non‐therapeutic resolute reading of the Tractatus that explains how Wittgenstein thought to be able to make a positive contribution to logic and the philosophy thereof without putting forward any (ineffable) theses. This explains why there is no paradox in the Tractatus.     

The Functional Complexity of Scientific Evidence

This article sketches the main features of traditional philosophical models of evidence, indicating idealizations in such models that it regards as doing more harm than good. It then proceeds to elaborate on an alternative model of evidence that is functionalist, complex, dynamic, and contextual, a view the author calls dynamic evidential functionalism (DEF). This alternative builds on insights from philosophy of scientific practice, Kuhnian philosophy of science, pragmatist epistemology, philosophy of experimentation, and functionalist philosophy of mind. Along the way, the article raises concerns about the total evidence condition, requirements of certainty or incorrigibility on evidence, and accounts that restrict the type of things that can serve as evidence (to, for example, sense data, facts about particulars). DEF can also help us see the special value of novel predictions and experiments as evidence, as well as help us think about how to critically evaluate the putative evidence to determine whether it is evidence.     

Practical Intentionality and Transcendental Phenomenology as a Practical Philosophy

This paper will deal with the problem of practical intentionality in the transcendental phenomenology of Husserl. First, through an analysis of a passage found in Logical Investigations, I will show Husserl's earlier position with respect to the problem of practical intentionality. I will then go on to critically assess this position and, with reference to some of Husserl's works written after the 1920's, prove that every intentionality should be regarded as a practical intentionality. Correspondingly, transcendental phenomenology should also be characterized as a practical philosophy. I make this statement with the following two senses in mind; transcendental phenomenology is a practical philosophy, first, in the sense that it investigates the various forms of practical intentionality and, second, in the sense that transcendental intentionality as the grounding source of transcendental phenomenology is also a kind of practical intentionality.     

Self-Defense,Forfeiture, and Necessity

Abstract

The thesis of this paper is that it is possible to explain why a culpable aggressor forfeits his right not to suffer the harm necessary to prevent his aggression if a killer forfeits his right to life. I argue that this strategy accounts also for the necessity restriction on self-defense. I respond to several objections, including the worry that it makes no sense to attempt a derivation of the relatively uncontroversial (aggressor’s forfeiture) from the highly controversial (killer’s forfeiture).     

Avicenna on the Primary Propositions

Avicenna introduces the primary propositions (or the primaries, for short) as the most fundamental principles of knowledge. (In this paper, we are not primarily concerned with the primary/first intelligibles as concepts/conceptions.) However, as far as we are aware, Avicenna’s primaries have not yet been independently studied. Nor do Avicenna scholars agree on how to characterize them in the language of contemporary philosophy. It is well-known that the primaries are indemonstrable; nonetheless, it is not clear what the genealogy of the primaries is (§2), how, epistemologically speaking, they can be distinguished from other principles (§3), what their phenomenology is (§4), what the cause of the assent to them is (§5), how to explain the relationship between the ‘innate [nature] of the intellect’ and the primaries (§6) and, finally, back to their indemonstrability, in what sense they are ‘indemonstrable’ (§7). We will try to fill this gap. As a corollary, we will explain why Gutas’s view [Gutas, Dimitri. 2012. ‘The empiricism of Avicenna’, Oriens, 40, 391–436], among others, according to which the primaries are analytic (in the Kantian sense) is not true in general (§8). More particularly, we will argue that some primary propositions can be categorized under Kantian synthetic a priori, consistent with Black’s and Ardeshir’s conjecture [Black, Deborah L. 2013. ‘Certitude, justification, and the principles of knowledge in Avicenna’s epistemology’, in Peter Adamson, Interpreting Avicenna: Critical Essays, New York: Cambridge University Press; Ardeshir, Mohammad. 2008. ‘Ibn Sīnā’s philosophy of mathematics’, in S. Rahman, T. Street, and H. Tahiri, The Unity of Science in the Arabic Tradition, New York: Springer]. We hope that this work opens up some space to study Avicenna’s philosophy of mathematics and logic in connection with his epistemology, philosophy of mind and metaphysics.     

What Could Turn Out,Actually Speaking

In this paper I distinguish three senses of could turn out/couldhave turned out in an attempt to elucidate how each is connected tothe notion of discovery and how each determines that a statement ofthe form `X could turn out P' (`X could have turned out P') is true.I argue that the actuality-oriented sense of could turn outbest captures what we ordinarily mean when we use could turnout or could have turned out in a nonevidential sense.     

How to Define a Number? A General Epistemological Account of Simon Stevin’s Art of Defining

This paper explores Simon Stevin’s l’Arithmétique of 1585, where we find a novel understanding of the concept of number. I will discuss the dynamics between his practice and philosophy of mathematics, and put it in the context of his general epistemological attitude. Subsequently, I will take a close look at his justificational concerns, and at how these are reflected in his inductive, a postiori and structuralist approach to investigating the numerical field. I will argue that Stevin’s renewed conceptualisation of the notion of number is a sort of “existential closure” of the numerical domain, founded upon the practice of his predecessors and contemporaries. Accordingly, I want to make clear that l’Aritmetique have to be read not as an ontological analysis or exploration of the numerical field, but as an explication of a mathematical ethos. In this sense, this article also intends to make a specific contribution to the broader issue of the “ethics of geometry.”     

WAYS OF DISCOURSE AND WAYS OF LIFE

In book X of the Republic, Plato famously reports “a quarrel between poetry and philosophy.” The present essay examines this quarrel in book X, along with other relevant parts of the Republic, by understanding “philosophy” and “poetry” as rival ways of life and rival ways of discourse. The essay first explains why, in Plato’s view, poetic discourse weakens one’s power to reason and is at odds with philosophic discourse. Then it shows how poetic discourse is bound up with a way of life that champions the value of freedom. Such a life forms a contrast with the philosophic life, which is marked more by stability and unity than by freedom. The quarrel, however, is not a simple antagonism. The essay hence concludes by discussing why, despite the opposition between the two, philosophy cannot do without poetry.
