Philosophical Investigations, EarlyView.

In a notorious passage from his Philosophical Investigations, Wittgenstein writes that one can state of the standard metre neither that it is one metre long, nor that it is not one metre long. While many commentators have rejected this claim, it has been commonly assumed that Wittgenstein himself endorsed it. In a recently published article, Thomas Müller not only provides a novel argument against Wittgenstein's claim about the standard metre but also claims that Wittgenstein did not actually endorse that claim. (...) In this paper, I argue that Müller's exegetical thesis is false and that his novel argument against Wittgenstein's claim about the standard metre is unsound. (shrink)

In this essay, I investigate the longstanding philosophical problem of whether we have control over our actions in a deterministic world. In working through a range of everyday situations in which this problem could arise, I come to the realisation that determinism has no bearing on whether we have control over our actions, because having control over our actions and determinism only make sense under different aspects.

Blum (Philosophical Investigations 46, 2023, 264) argues that Tarski's T‐schema and the thesis of the necessity of identity are mutually inconsistent. It is argued that his argument fails.

Pierre Hadot is best known as a historian of ancient philosophy and for advocating the relevance of ancient thinking for contemporary lives. What is less well known is that he was one of the first French philosophers to take a serious interest in the work of Wittgenstein, publishing between 1959 and 1962 two essays on the Tractatus and two on the Philosophical Investigations, since republished as Wittgenstein et les limites de langage (Paris: J. Vrin, 2010). Only two of these essays (...) are available (and not widely) in English translation. Part of my goal is to argue that they deserve the attention of anglophone readers. My focus here is on Hadot's remarks about the Philosophical Investigations. Hadot argues that this work produces a self‐defeating paradox because it claims that we can speak intelligibly only within a language‐game, but Wittgenstein, like the philosophers he criticises, tries to transcend language‐games in the presentation of his views. Despite this criticism, Hadot is inspired by Wittgenstein's discussion of the multiplicity of language‐games to argue that the texts of ancient philosophy are not part of the same language‐game as those of modern philosophy and must be approached as ‘spiritual exercises’, rather than as bodies of doctrine or theory. Wittgenstein is thus a key inspiration for Hadot's historiographical method. I argue that Hadot is too impressed by a faulty analogy between the Tractatus and the Investigations and that he gives a problematically reductive interpretation of Wittgenstein's talk of language‐games and implausibly attributes to Wittgenstein a reverence for ‘the ordinary’ that supposedly takes the place of his earlier wonder at the existence of the world. Many commentators since Hadot have made similar errors, so his case remains instructive. I conclude by suggesting, nonetheless, that something like Hadot's proposals about historiographical method may be justified by a better reading of the Investigations. (shrink)

The influence of Heinrich Hertz's The Principles of Mechanics on Ludwig Wittgenstein's Tractatus Logico‐Philosophicus has been studied for decades, but it has never become a mainstream topic in the Wittgensteinian literature. This paper focusses on Tractarian notions of objects, elementary facts and elementary sentences and discusses their similarities with Hertz's concepts of mass, its constituents and their mechanistic images. As the paper demonstrates, the Hertzian context provides some fruitful interpretational leads concerning several controversial ideas endorsed by early Wittgenstein, namely propositional (...) analysis, logical independence of elementary facts, logical independence of elementary sentences, and modalities.

In this discussion I argue that Peter Sullivan is wrong to suggest that Wittgenstein's position in the Philosophical Investigations involves a commitment to transcendental idealism. I show that Sullivan's interpretation involves holding that transcendental idealism was employed by Wittgenstein in the attempt to combat a Platonist mythology. I show, through a detailed appraisal of Wittgenstein's discussion of samples, that Wittgenstein's approach to Platonism does not involve any such employment of transcendental idealism. I conclude that there is no such motivation as (...) Sullivan finds in Wittgenstein for endorsing transcendental idealism, and that we ought not, therefore, ascribe to him such a view. (shrink)

This is a reply to ‘Defending Wittgenstein’, Piotr Dehnel's critique of my article, ‘Defending Wittgenstein's Remarks on Cantor from Putnam’. I first show that my position is much more in agreement with Felix Mühlhölzer than Dehnel takes it to be, and that his criticism of me is nothing more than a failure to recognize this. I then show how Dehnel incorrectly reads Wittgenstein as rejecting set theory as false. It is an overemphasis on and a much too narrow picture of (...) ‘applicability’ which leads him to this view. Finally, I conclude by rejecting Dehnel's view that Wittgenstein was a finitist about mathematics. (shrink)

Is ethics about anything? Cora Diamond has famously argued that ethics lacks a subject matter by providing a variety of examples of ethical discourse, which, she claims, are ethically significant without being about anything ethical. They do not have a moral subject matter, but are nonetheless instances of moral thinking. This raises the question what it means for a piece of discourse to be moral. What does Diamond mean by the concept of ethics? Diamond never gives this question a direct (...) answer, which is a cause for concern, among other things because there is reason to worry that any workable account of the concept of ethics will lead back to the idea that ethics has a subject matter. I explain how this worry can be averted by construing the concept of ethics as a family resemblance concept. (shrink)
