Ludwig Wittgenstein (1889-1951) is considered by most philosophers - even those who do not share his views - to be the most influential philosopher of the 20 th century. His contributions to the philosophy of language, mind, meaning and psychology - as well as to logic, mathematics and epistemology - permanently altered the philosophical landscape, and his _Tractatus Logico Philosophicus_ and _Philosophical Investigations_ continue to be studied in philosophy departments around in the world. In this superb introduction and overview of Wittgenstein’s life and work, William Child discusses: Wittgenstein’s early work, _Tractatus Logico-Philosophicus_, including his account of language and thought Wittgenstein’s subsequent rejection of some of the central doctrines of the _Tractatus_ Wittgenstein’s later philosophy intentionality and rule-following philosophy of mind and psychology in _Philosophical Investigations_ knowledge and certainty, and Wittgenstein’s final work philosophy of religion the legacy and influence of Wittgenstein’s ideas in philosophy, and beyond. Including a chronology, glossary, and helpful conclusions to each chapter, _Wittgenstein _is essential reading for anyone coming to Wittgenstein's philosophy for the first time.

Timothy Williamson has argued that a theory of content-determination should focus on knowledge rather than truth; the principle of charity, which says that interpretation should maximize (or optimize) true belief, should be replaced by a principle of knowledge-maximization, which says that interpretation should maximize knowledge. Williamson contends that knowledge-maximization has two important advantages over charity: it generates the right assignments of content in cases that the principle of charity gets wrong; and it can readily explain the fact that people often know, a fact that cannot be generated from the principle that beliefs are generally true. The paper explores the effectiveness of these criticisms of Donald Davidson’s principle of charity. It is argued that Davidson has an effective response to the charge that charity generates implausible assignments of content. If there is a failing in his account, it is not that it yields the wrong assignments but that it does not adequately explain the role of perception in content-determination. It is conceded that Davidson himself does not forge a convincing link between charity and knowledge. The significance of that fact is considered.

Publication of scientific and biomedical manuscripts in “high impact factor” (IF) journals is important in advancing careers, obtaining funding, and developing a field of research. Rejection by prestigious journals is not infrequent and usually painful, especially to young investigators. Reasons provided by an editor are often confusing. We assess the language of the rejection letter from a specific philosophical stance, originated by Ludwig Wittgenstein. Wittgenstein’s late writings on language as usage and as inherent to human activity have profoundly influenced many of the humanities but have been less frequently applied to the sciences. However, Wittgenstein’s ideas about language have relevance for understanding editorial correspondence and also, more broadly, for our thinking about scientific work and “science.”

The paper discusses two aspects of Wittgenstein’s middle-period discussions of the self and the use of ‘I’. First, it considers the distinction Wittgenstein draws in his 1933 Cambridge lectures between two ‘utterly different’ uses of the word ‘I’. It is shown that Wittgenstein’s discussion describes a number of different and non-equivalent distinctions between uses of ‘I’. It is argued that his claims about some of these distinctions are defensible but that his reasoning in other cases is unconvincing. Second, the paper considers the distinction drawn in the Blue Book between the use of ‘I’ as subject and the use of ‘I’ as object. A number of commentators have contended that this Blue Book distinction between uses of ‘I’ is erroneous, that Wittgenstein soon realized that, and that he dropped the idea of such a distinction from his later work. Against those claims, it is argued that Wittgenstein’s distinction between the use of ‘I’ as subject and its use as object is correct and illuminating. And it is shown that, though we do not find the ‘as-subject’/’as-object’ terminology in Wittgenstein’s subsequent work, the essential point of the Blue Book distinction is not abandoned but remains in place in Philosophical Investigations.

Donald Davidson offers an explanation of first‐person authority that “traces the source of the authority to a necessary feature of the interpretation of speech.” His account is explained, and an interpretation is offered of its two key ingredients: the idea that by using the device of disquotation, a speaker can state the meanings of her words in a specially error‐free way, and the idea that a speaker cannot generally misuse her own words, because it is that use that gives her words their meaning. The account is defended against misinterpretations and criticisms. But it is argued that Davidson does not explain what is most puzzling about our knowledge of the meanings of our words, or about the asymmetry between our knowledge of our own minds and our knowledge of others' minds. Finally, Davidson's argument for the compatibility of first person authority and semantic externalism is explained and defended.

This chapter distinguishes two uses of the terms “inner” and “outer” in Wittgenstein's writings on philosophy of mind. It discusses the inner‐outer picture by exploring Wittgenstein's account of the origin and appeal of the picture, his reasons for rejecting it, and his own very different way of thinking of common‐sense psychology. The chapter considers his account of our relation to our own experiences and attitudes, and discusses his suggestion that utterances like 'I'm in pain' or 'I want an apple' are avowals or expressions of a person's experiences and attitudes. It discusses Wittgenstein's positive view of the relation between “inner” mental states and “outer” behavior. The inner–outer picture, as Wittgenstein describes it, has a metaphysical and an epistemic dimension. The inner–outer picture encourages the view that our use of language in self‐ascriptions of current experiences and attitudes is analogous to its use in talking about the non‐mental world.

Part 1 of this paper sketches Wittgenstein’s opposition to scientism in general. Part 2 explores his opposition to scientism in philosophy focusing, in particular, on philosophy of mind; how must philosophy of mind proceed if it is to avoid the kind of scientism that Wittgenstein complains about? Part 3 examines a central anti-scientistic strand in Wittgenstein’s Last Writings on the Philosophy of Psychology volume II: his treatment of the ‘uncertainty’ of the relation between ‘outer’ behaviour and ‘inner’ experiences and mental states.

Wittgenstein’s philosophy involves a general anti-platonism about properties or standards of similarity. On his view, what it is for one thing to have the same property as another is not dictated by reality itself; it depends on our classificatory practices and the standards of similarity they embody. Wittgenstein’s anti-platonism plays an important role in the private language sections and in his discussion of the conceptual problem of other minds. In sharp contrast to Wittgenstein’s views stands the contemporary doctrine of natural properties, which holds that there is an objective hierarchy of naturalness amongst properties, a hierarchy that is completely independent of our concepts or practices. Some authors have appealed to the natural properties view to offer an explicitly anti-Wittgensteinian account of sensation concepts. The paper discusses these competing views of properties and sensation concepts. It is argued that, if our account of concepts of conscious states starts from a commitment to natural properties, we are bound to recognize that our actual classificatory practices also play a crucial role in determining which properties our concepts pick out. On the other hand, if we start from the anti-platonist position, we are bound to recognize that we also need a notion of sameness of property that extends beyond our limited capacity to recognize similarity or sameness of property. The correct view, it is concluded, must occupy a middle position between an extreme anti-realism about properties and an extreme version of the natural properties view. It is suggested that Wittgenstein’s own view does just that.

It is natural to say that when we acquire a new concept or concepts, or grasp a new theory, or master a new practice, we come to see things in a new way: we perceive phenomena that we were not previously aware of; we come to see patterns or connections that we did not previously see. That natural idea has been applied in many areas, including the philosophy of science, the philosophy of religion, and the philosophy of language. And, in reflecting on the character of philosophy itself, Wittgenstein himself associates the introduction of a new concept in philosophy with the discovery of a new way of looking at things (PI §401), and says that the point of presenting us with an imagined example may be to change our way of looking at things (PI §144). The paper considers four interrelated questions about this association between seeing-as and change, novelty, or innovation. 1. Is there an important difference between the case where the change in someone’s way of seeing things involves the invention or discovery of a completely new concept, a completely new theory etc., and the case where it involves the person’s coming to understand an existing concept or theory? 2. Is there a special connection between seeing-as and conceptual or theoretical change or creativity: a connection that does not obtain between seeing-as and using or applying a familiar theory or system of concepts? 3. In cases where seeing-as is associated with novelty or creativity, is there any sense in which the fact that someone sees things in a new way can help to explain their conceptual or theoretical creativity? 4. To the extent that there is some association between seeing-as and novelty or creativity, why if at all does it matter that one experiences things in a certain way? Would someone who was aspect-blind be any worse off with respect to creativity or innovation than the rest of us? And if so, why?

A central theme in Wittgenstein’s post-Tractatus remarks on the limits of language is that we ‘cannot use language to get outside language’. One illustration of that idea is his comment that, once we have described the procedure of teaching and learning a rule, we have ‘said everything that can be said about acting correctly according to the rule’; ‘we can go no further’. That, it is argued, is an expression of anti-reductionism about meaning and rules. A framework is presented for assessing the debate between reductionist and anti-reductionist readings of Wittgenstein’s views about meaning and use. It is argued that that debate cannot be settled merely by reference to Wittgenstein’s general opposition to reductionism. An important argument for anti-reductionism about rules and meaning, from Remarks on the Foundations of Mathematics, is discussed. Putative evidence of reductionism about meaning in the Brown Book is considered; an alternative reading is proposed. The nature of Wittgenstein’s anti-reductionism is examined. It is argued, first, that Wittgenstein accepts that semantic and normative facts supervene on non-semantic, non-normative facts and, second, that at many points his treatment of meaning and rules goes beyond the kind of pleonastic claim that is often taken to define non-reductionist, quietist, positions in philosophy.

Defends the causal theory of vision and the disjunctive conception of visual experience and argues that they can be coherently combined. Reasons are given for accepting the causal theory of vision and the disjunctive conception of experience. Then, an objection is set out, according to which the disjunctive conception undermines the causal theory, either because the disjunctive conception is incompatible with the idea that visual experiences are caused by the objects we see or because the disjunctive conception removes the main motivation for accepting a causal theory. Against this objection, it is shown how a disjunctive conception of experience can be combined with the causal theory. And it is argued that, even if we accept the disjunctive conception, the causal theory is still needed in order to understand two features of experiences: why they occur and how they have the objective content they do.

Interpretation is the process of ascribing propositional attitudes to an individual on the basis of what she says and does. Interpretationism is the view that we can gain an understanding of the nature of the mental by reflecting on the nature of interpretation. The chapter examines the arguments for and against holding that the interpretation of propositional attitudes is inseparable from the interpretation of language, that being interpretable as possessing a given attitude is a necessary condition for possessing it, and that being interpretable as possessing an attitude is sufficient for possessing it. And it discusses whether interpretationists should claim that being interpretable as having thoughts is actually constitutive of having thoughts.

Introduces and explains the basic argument for a causal theory of action‐explanation, and defends it against various non‐causal views of action: explaining an action is explaining why something happened, and an explanation of why something happened is always a causal explanation. But what is involved in the claim that reason‐explanation is a form of causal explanation? The chapter begins to answer that question. First, it considers the relation between causal explanation, on the one hand, and the singular relation of causation, on the other. Second, it considers the relation between mental causation and physical causation, defending the idea that we cannot take a purely mentalist view of mental causation.

Interpretationism in the philosophy of mind is often thought to conflict with the idea that beliefs and desires play a genuinely causal role. It is argued that there is in fact no such conflict and that a causal understanding of the mental is essential for realism about mental phenomena and about the relations between thought and reality. First, the chapter considers and responds to various reasons for thinking that the metaphysics of interpretationism is incompatible with a causal view of the mental. Then it examines the view of philosophers who accept that rationalizing, interpretative stories and causal stories are both legitimate, but argue that no single account of anything can be simultaneously rationalizing and causal. Against that view, it is argued that, unless we see interpretative, psychological stories as themselves being causal stories, we cannot understand psychological explanation and we cannot understand how thought and experience can have the objective content they do.

If mental causal explanations are grounded in facts about physical causes and effects, and if there are no psychophysical laws, how can we avoid the conclusion that the mental is causally, and causally explanatorily, irrelevant? The chapter analyses the ways in which this objection has been raised against non‐reductive monism in general, and Davidson's anomalous monism in particular. Then a conception of explanatory relevance for non‐basic physical properties is set out: properties are candidates for explanatory relevance if they play a role in a simple model of causal action; it is intelligible how a property can be causally explanatorily relevant only if it supervenes on low‐level physical properties; but such supervenience does not provide a self‐standing condition of explanatory relevance. A parallel model is developed for the mental case, exploiting the intuitive model of rational action and appealing to supervenience. Anomalous monism is thereby defended against one objection; but, it is argued, this defence challenges the original motivation for thinking that mental events must be physical events.

Examines the arguments for the anomalism of the mental. It is argued that the basis for the anomalism of the mental is the principle that rationality is uncodifiable, and that principle is defended. It is shown that the anomalism of the mental, and the uncodifiability of rationality that underlies it, is compatible with the supervenience of the mental on the physical, but that it rules out most varieties of functionalism. It is argued that the uncodifiability of rationality rules out token identity or token correlation between particular mental states or events and particular physical states or events.

The paper considers three questions. First, what is the connection between economics and agency? It is argued that causation and explanation in economics fundamentally depend on agency. So a philosophical understanding of economic explanation must be sensitive to an understanding of agency. Second, what is the connection between agency and causation? A causal view of agency-involving explanation is defended against a number of arguments from the resurgent noncausalist tradition in the literature on agency and action-explanation. If agency is fundamental to economic explanation, it is argued, then so is causation. Third, what is the connection between causal explanation and the natural sciences? It is argued that, though the explanations given in economics and other social sciences are causal explanations, they are different in kind from the causal explanations of the natural sciences. On the one hand, then, the causal explanations of the social sciences are irreducible to those found in the natural sciences. On the other hand, the causal relations described by the social sciences are not completely autonomous; they do not float free of, or operate independently from, the causal relations charted by the natural sciences.

What is the relation between meaning and use? This chapter first defends a non-reductionist understanding of Wittgenstein’s suggestion that ‘the meaning of a word is its use in the language’; facts about meaning cannot be reduced to, or explained in terms of, facts about use, characterized non-semantically. Nonetheless, it is contended, facts about meaning do supervene on non-semantic facts about use. That supervenience thesis is suggested by comments of Wittgenstein’s and is consistent with his view of meaning and rule-following. Semantic supervenience is then defended against two criticisms: first, John McDowell’s suggestion that the supervenience thesis falsifies the epistemology of meaning and fails to accommodate common-sense truths about meaning; second, a series of counter-examples proposed by Stephen Kearns and Ofra Magidor, who argue that worlds may differ semantically without differing non-semantically. It is argued that neither criticism is convincing: we should accept the thesis that semantic facts supervene on non-semantic facts.

Is there a plausible middle position in the debate between realists and constructivists about categories or kinds? Such a position may seem to be contained in the account of triangulation that Donald Davidson develops in recent writings. On this account, the kinds we pick out are determined by an interaction between our shared similarity responses and causal relations between us and tilings in our environment. So kinds and categories are neither imposed on us by the nature of the world, nor imposed by us on an intrinsically unstructured reality. But the picture derivable from Davidson's account of triangulation can be interpreted in either of two ways. On one interpretation, it collapses into constructivism. On the other, it turns out to be very close to the most plausible versions of realism. It is argued that Davidson's attempts to distinguish his view from Putnam's realism about natural kinds are unsuccessful. So Davidson's account of triangulation does indeed suggest a plausible view of kinds. But that view is a version of traditional realist views, not an alternative to them.
