In theTractatus, Wittgenstein advocates two major notational innovations in logic. First, identity is to be expressed by identity of the sign only, not by a sign for identity. Secondly, only one logical operator, called “N” by Wittgenstein, should be employed in the construction of compound formulas. We show that, despite claims to the contrary in the literature, both of these proposals can be realized, severally and jointly, in expressively complete systems of first-order logic. Building on early work of Hintikka’s, we (...) identify three ways in which the first notational convention can be implemented, show that two of these are compatible with the text of theTractatus, and argue on systematic and historical grounds, adducing posthumous work of Ramsey’s, for one of these as Wittgenstein’s envisaged method. With respect to the second Tractarian proposal, we discuss how Wittgenstein distinguished between general and non-general propositions and argue that, claims to the contrary notwithstanding, an expressively adequate N-operator notation is implicit in theTractatuswhen taken in its intellectual environment. We finally introduce a variety of sound and complete tableau calculi for first-order logics formulated in a Wittgensteinian notation. The first of these is based on the contemporary notion of logical truth as truth in all structures. The others take into account the Tractarian notion of logical truth as truth in all structures over one fixed universe of objects. Here the appropriate tableau rules depend on whether this universe is infinite or finite in size, and in the latter case on its exact finite cardinality.As it is obviously easy to express how propositions can be constructed by means of this operation and how propositions are not to be constructed by means of it, this must be capable of exact expression.5.503.

I defend a new interpretation of Wittgenstein's notion of religious attitude in the Tractatus , one that rejects three key views from the secondary literature: firstly, the view that, for Wittgenstein, the willing subject is a transcendental condition for the religious attitude; secondly, the view that the religious attitude is an emotive response to the world or something closely modelled on this notion of emotive response; and thirdly, the view that, although the religious and ethical pseudo-propositions of the Tractatus are (...) nonsensical, they nevertheless succeed in expressing the religious attitude endorsed by Wittgenstein. In connection to the first, I argue that the notion of willing subject as transcendental condition is abandoned by Wittgenstein in the Notebooks and is no longer a feature of his position in the Tractatus . In connection to the second, I argue that the religious attitude is dispositional rather than emotive for Wittgenstein: it is a disposition to use signs in a way that demonstrates one's conceptual clarity. Finally, in connection to the third, I argue that the religious or ethical attitude is strongly ineffable in that it cannot be described, expressed or conveyed by language at all. (shrink)

In this paper I offer a novel interpretation of Wittgenstein's claim that ‘ethics is transcendental’. Initially, I set out to offer said interpretation by resorting to both Wittgenstein's understanding of ethics and his understanding of the transcendentality of logic—which entails taking Wittgenstein as endorsing a Kantian understanding of the notion ‘transcendental’. This leads to the claim that ethics is transcendental insofar as it is the condition of a certain ethical experience. Nevertheless, this interpretation involves some inadequacies due to certain incompatibilities (...) between the Tractatus Logico-Philosophicus and the aforementioned Kantian understanding of the notion ‘transcendental’. I identify the peculiarities of Wittgenstein's understanding of the notion ‘transcendental’, and on this basis, I set forth a novel interpretation of 6.421. Specifically, I argue that ethics is transcendental insofar as it is internal to or constitutive of a certain mystical view: viewing the world sub specie aeterni as something valuable. (shrink)

A lack of consensus persists as to whom exactly the dialogues of Wittgenstein's Philosophical Investigations are between: Wittgenstein and an interlocutor? Or perhaps a variety of interlocutors, none of whom can be identified with Wittgenstein himself? I argue here that this lack of consensus is possibly due to an ambiguity in the ordinary concept of “talking to oneself,” and that a new concept of “talking to oneself” appropriate to Wittgenstein's dialogues is needed to properly understand them. Wittgenstein is talking to (...) himself—but he is doing so in the way we talk to other people. (shrink)

In the so-called private language argument, Wittgenstein argues both against the alleged epistemological privacy of sensations and against their alleged ontological privacy, that is, the common view that somebody else cannot have my pain. A prominent proponent of the claim of sensations' ontological privacy was Gottlob Frege, whose position has recently been defended by Wolfgang Künne. This paper reconsiders Wittgenstein's objections to ontological privacy and attempts to defend Wittgenstein's position against Künne's Frege-inspired arguments.

In this paper I offer a genetic account of how Wittgenstein developed his ideas on aesthetics in his 1933 lectures. He argued that the word ‘beautiful’ is neither the name of a particular perceptible quality, nor the name of whatever produces a certain psychological effect, and unlike ‘good’, it does not stand for a family-resemblance concept either. Rather, the word ‘beautiful’ has different meanings in different contexts as we apply it according to different criteria. However, in more advanced regions of (...) aesthetics the word ‘beautiful’ ceases to play an important role. Instead, we judge things to be more or less correct according to genre-specific standards or criteria, which in an aesthetic discussion are presupposed, rather than argued for. Finally, Wittgenstein came to realise that providing support for an aesthetic appraisal according to some given criteria is not the only and perhaps not even the main focus of aesthetic discussion. More interesting to him became the idea of a puzzle or perplexity in aesthetics, which he discussed in greater detail in his 1938 lectures. (shrink)

Although cognitive neuroscience mainly studies the biological underpinnings and neuronal processes of human cognition, cognitive scientists have quite recently recognized that the external world, including both the natural environment and the cultural and social settings, may affect and modify human cognitive abilities. In this chapter, I intend to highlight that the most recent cognitive theories, mainly developed in the field of the study of religion, remove the dualism between brain and body and promote a multifaceted conception of human cognition, which (...) embraces the body, the brain and the world. In this framework, my intention is to indicate points of convergence between cognitive approaches and Wittgenstein’s philosophical considerations, and potentially to outline new directions for further discussions between cognitive theoreticians and Wittgensteinian philosophers. In particular, I claim that interdisciplinary collaboration between cognitive scientists, historians and philosophers may deepen our understanding of human beings and of the ways in which humans subjectively perceive the world and develop multiple worldviews.
