This paper is about what might be called the philosophical tradition of ethics, and Wittgenstein’s opposition or hostility to that tradition. My aim will be to argue that ethics, or a large part of what we think of as ethics, is nonsense, and in doing so I shall be developing the line of argument that I take to lie behind Wittgenstein’s claim in the Tractatus Logico-Philosophicus that there can be no ethical propositions. That argument has its basis in the simple thought that value is not arbitrary or accidental, and what I shall show is how thinking through what is involved in that thought leads to a radically different conception of the possibilities open to ethical thinking than that which is assumed within the prevailing conception of ethics today.

This essay is concerned with the question whether there is anything left of the Tractatus criticisms of Frege and Russell, if the principles on which those criticisms are apparently based are “thrown away.” I consider two examples of Tractarian arguments that criticize Russell, both of which may appear to rest on the context principle. I discuss only briefly Wittgenstein’s argument against Russell on the theory of types, but I look in detail at his criticism of Russell on generality. I show how that criticism can be understood independently of any supposed Tractarian principles. I also consider the importance of ideas in Russell’s Principles of Mathematics for the development of Wittgenstein’s thought, including the distinction between saying and showing.

In this paper I want to argue that a unified set of concerns constituting a new dimension—a realignment of our sense of language, self, and world—emerges in the progress of the Tractatus as we turn to inquire into the inner connection between language and such notions as world, limits, life, and ipseity. The most elusive step in that progress, and the one most necessary to recognize as part of the argument of the Tractatus, is the transition from an understanding of language in terms of logic, sense, and meaning to a perspective in which language becomes the primary locus of significance or meaningfulness (that is, meaning that has value or importance). It is also the pivot from the logical to the ethical concerns of the book. An ethics that appeals to the notion of meaningfulness is elaborated in terms of the dimension of existence, namely in terms of the very possibility of agreement of disagreement with what has ultimate reality.

Which concept is the more primitive when it comes to the functioning of the logical constants: representation or inference? Via a discussion of Arthur Prior’s famous mock connective “tonk” and a couple of responses to Prior by J. T. Stevenson and Nuel Belnap, it is argued that early Wittgenstein’s answer is neither. Instead, he takes representation and inference to be equally basic and mutually dependent notions. The nature and significance of this mutual dependence is made clear by an investigation into the Tractarian notion of a proposition. It is further argued that even if Wittgenstein later abandoned the Tractarian conception of what a proposition is, he never gave up the idea that inference and representation play interdependent and equally fundamental roles in logic.

What is it to read Wittgenstein resolutely? In this essay, I make a suggestion about how to answer that question. I backtrack in time to a debate about Philosophical Investigations (PI) between O. K. Bouwsma and Gilbert Ryle. I selectively reconstruct that debate, highlighting features of it that I take to be interesting in their own right and in relation to debates about PI, but also interesting in analogy with debates about resolute and standard readings of Tractatus logico-philosophicus (TLP). As will be clear, my sympathies are with Bouwsma against Ryle, and with resolute readers against standard readers. But I do not vindicate Bouwsma; I will, in fact, be critical, carefully or guardedly critical of him.Nor do I vindicate resolute reading of TLP. I suggest a way of seeing resolute reading that makes clearer what it is and how it contrasts with standard reading, and, in so doing, that makes clearer what some of the difficulties of the debate between the readings really are, whether about TLP or about PI.

This paper develops an account of Wittgenstein’s method of language-games as a method of logic that exhibits important continuities with Russell’s and the early Wittgenstein’s conceptions of logic and logical analysis as the method of philosophy. On the proposed interpretation, the method of language-games is a method for isolating and modeling aspects of the uses of linguistic expressions embedded in human activities that enables one to make perspicuous complex uses of expressions by gradually building up the complexity of clarificatory models. Wittgenstein’s introduction of the language-game method constitutes an attempt to overcome certain limitations of calculus-based logical methods, and to respond in this way to problems with Russell’s and his own early philosophy of logic. The method is nevertheless compatible with the employment of calculus-based methods in logic and philosophy, and makes no exclusive claim to being the correct method.

This paper explores difficulties that resolute readers of the early Wittgenstein face, arising out of what I call the ‘sheer lack’ interpretation of their ‘austere’ conception of nonsense, and the intelligibility of philosophical confusion—there being a sense in which we rightly talk of a ‘grasp’ of philosophical nonsense and indeed of its ‘logic’. Such readers depict philosophical and ‘plain’ nonsense as distinct psychological kinds; but I argue that the ‘intelligibility’ of philosophical confusion remains invisible to the kind of psychology that the ‘sheer lack’ interpretation would make available to Wittgenstein. These concerns relate to well-established worries concerning whether the Tractatus’s ‘ladder’ can be climbed by thinking through arguments—or indeed by thinking full stop—if it is austerely nonsensical. Though I argue that these worries can be met, doing so requires another interpretation of ‘austerity’, which I call the ‘equivocation’ interpretation, and reveals the difference between resolute and non-resolute readings to be less clear cut than has been thought. Key here is the failure of some hard-and-fast distinctions that inform the literature—distinctions shaped by intuitions about mind, meaning, inference, logic, and nonsense—to serve us well.

In this essay, I take up James Conant and Cora Diamond’s suggestion that “to take the difference between saying and showing deeply enough is not to give up on showing but to give up on picturing it as a ‘what’ ” (Conant and Diamond 2004, 63). I try to establish that the Tractatus’s talk of “showing” (zeigen) is more coherent than is usually appreciated, that it is indeed a key to the internal unity of the book (as its author claimed), and that it positively helps us to work our way into the practice of philosophy, which its author understood as a practice of logical clarification. Thus, it is not a stretch of latent nonsense whose sole function is to conjure up an illusion of sense for the sake of displaying its disintegration. While Wittgenstein’s concept of showing is not meant to “make up for” the impossibility of saying certain things, neither does it stand in need of being “redeemed.” Whether or not it is to prove ultimately (or even wholly) coherent, the Tractatus’s talk of “showing,” I shall argue, is certainly not to be “thrown away” in the name of the Tractarian conception of logic (we cannot make mistakes in [on behalf of] logic), for the simple reason that it essentially belongs with it.

The first section of the paper argues that, in the context of Wittgenstein’s intentional understanding of the truth-functional construction of sentences, the independence of elementary sentences is required for every application of a truth-operation to have the same significance. The second section of the paper presents a ‘top-down’ interpretation of Tractarian analysis. There is no characterization of the bottom level of analysis apart from the general sentence-form; the only constraint on analysis is that apparently manifest logical relationships among colloquial sentences with sense be represented or otherwise accommodated using only the logical resources built into the general sentence-form. The third section of the paper considers how those logical resources might be applied in Tractarian analysis. Central here is the use of form-series to construct infinitary truth-functions. The section develops a view of Tractarian complexes which accommodates some colloquially manifest logical relations as presuppositions that are made explicit in analysis. Finally, I note that Tractarian analysis, as presented in this paper, is immune to the ‘color exclusion’ objection as formulated in Wittgenstein’s 1929 paper “Some Remarks on Logical Form.”

In this paper I advance an account of the necessity of logic in Wittgenstein’s Tractatus. I reject both the “metaphysical” reading of Peter Hacker, who takes Tractarian logical necessity to consist in the mode of truth of tautologies, and the “resolute” account of Cora Diamond, who argues that all Tractarian talk of necessity is to be thrown away. I urge an alternative conception based on remarks 3.342 and 6.124. Necessity consists in what is not arbitrary (nicht willkurlich), and contingency in what is up to our arbitrary choice (willkurlich), in the symbols we use, in how we picture or model the world. Necessity is not a mode of truth of propositions, but lies in the requirements of their intelligibility. I argue that this conception is implicit in certain “resolute” readings and in some of their critics. Both sides of the dispute are committed to certain logical features of language or thought, patterns of symbolizing constitutive of intelligibility that are not up to us to institute or alter. This conception of non-arbitrary patterns of symbolizing, I argue, is what logical syntax in the Tractatus consists in. I also argue that the well-known Tractarian view of propositions as truth-functions of elementary propositions can be understood in terms of patterns of norms governing our making sense with the affirmation and denial of propositions.

In the Preface of the Tractatus Wittgenstein presents his proposal of “drawing limits” separating sense from nonsense as a way to get rid of philosophical problems caused by “misunderstandings of the logic of our language.” Such limits, we will later discover, will be drawn by means of a method which allows one to determine whether a given projection of a strings of signs was made in accordance with the rules of logical syntax, or else violated them, thus generating (pseudo) metaphysical propositions (6.53). Notwithstanding its centrality for the Tractatus, the idea of drawing such limits seems to be in tension with Wittgenstein’s actual procedure in most of the book, which from its very first numbered proposition introduces “metaphysical” (pseudo?) theses again and again in order to achieve the results programmatically indicated in the Preface—hence the need for the self-undoing message of 6.54, urging the reader to recognize those propositions “as nonsensical, when he has used them—as steps—to climb up beyond them.” That tension creates some of the most challenging questions in the debate about how to read the Tractatus—questions such as: how are we supposed to use Wittgenstein’s propositions (and which ones?) as “steps in a ladder”? What exactly does “throwing the ladder away” amount to? And what does it mean to “see the world aright” after “overcoming” those propositions? This paper attempts to answer those questions by means of a close reading of an exemplary set of propositions dealing with solipsism and the limits of language (5.6n’s). Although limited in scope, the hope is that such reading might stand as a test case for parallel readings of other parts of the book.
