Summary

Ludwig Wittgenstein (1889-1951) was an Austrian philosopher whom many regard to have been the most important philosopher of the twentieth century. His work is often divided into two distinct periods, early and later, with the division occurring at some point shortly after his return to Cambridge in 1929 following a period of self-imposed exile as, among other things, a village school-teacher, monastery gardener, and architect. Wittgenstein wrote extensively on many topics including the philosophy of language, logic, mathematics and mind though he published little during his lifetime. His work is distinctive particularly for his claim that philosophy is for the most part nonsense, his aim being to bring to light the confusions that give to it the appearance of sense.

Key works Wittgenstein’s most important works are the Tractatus Logico-Philosophicus (first published in English in 1922) and the Philosophical Investigations (first published posthumously in 1953). The nature and extent of the continuity between these two works is a matter of great controversy, with one extreme representing them as offering fundamentally opposed philosophies and another treating the differences as largely stylistic. Among the many other works produced from his manuscripts and notebooks, Wittgenstein’s On Certainty, compiled from notes made in the two years before his death, is sometimes regarded as his third “masterpiece”.
Introductions There are many good introductions to Wittgenstein's thought. Monk 2005 and Hacker 1999 are both short and accessible. More in-depth, but still engaging, are Child 2011, Kenny 1973, and Sluga 2011. Dean Jolley 2010 contains a good selection of essays on central topics. McGinn 2006 and McGinn 2013 provide in-depth introductions to the Tractatus and Philosophical Investigations, respectively.

    τὰ ὄντα ἰέναι τε πάντα καὶ μένειν οὐδέν: Another look at being, asking what a interlocutor means to show by saying they feel themselves to be something. An ambiguity of the verb "to be" is disambiguated to reveal that it can be meant to show what something is and a process of being something. The relationship between being and essence is made by describing engagement through the encounter, giving us a non-exhaustive account of something's essence. Practice is then understood as (...)

  2. On the exhaustion criterion of difficulty, with Wittgenstein, Robert Graves, and Kripke.Terence Rajivan Edward - manuscript
    The philosopher and builder Ludwig Wittgenstein remarks that architecture is more difficult than philosophy. He suggests an exhaustion criterion for how difficult a discipline is: a field is more difficult the more exhausting it is. I make a case against this claim. There was once a demand to prevent the Greek myths from establishing themselves in the curriculum by means of “our own rival myths.” It is difficult to compete with a renowned Greek myth, but if one does produce a (...)

    This paper considers the debate between teams of skilled contributors versus a genius by focusing on a specific case: a team project to overturn some remarks by Wittgenstein on Frazer’s The Golden Bough. In theory, there can be a team which does this, but in actual practice, such a team seems unlikely to arise.

    We propose the concepts of philomatics and psychomatics as hybrid combinations of philosophy and psychology with mathematics. We explain four motivations for this combination which are fulfilling the desire of analytical philosophy, proposing science of philosophy, justifying mathematical algorithms by philosophy, and abstraction in both philosophy and mathematics. We enumerate various examples for philomatics and psychomatics, some of which are explained in more depth. The first example is the analysis of relation between the context principle, semantic holism, and the usage (...)

    Coping with everyday life limits the extent of one’s scepticism. It is practically impossible to doubt the existence of the things with which one is immediately engaged and interacting. To doubt that, say, a door exists, is to step back from merely using the door (opening it) and to reflect on it in a detached, theoretical way. It is impossible to simultaneously act and live immersed in situation S while doubting that one is in S. Sceptical doubts—such as ‘Is this (...)

    In Zettel, Wittgenstein considered a modified version of Cantor’s diagonal argument. According to Wittgenstein, Cantor’s number, different with other numbers, is defined based on a countable set. If Cantor’s number belongs to the countable set, the definition of Cantor’s number become incomplete. Therefore, Cantor’s number is not a number at all in this context. We can see some examples in the form of recursive functions. The definition "f(a)=f(a)" can not decide anything about the value of f(a). The definiton is incomplete. (...)

Contrasting those who consider Wittgenstein’s Judaism as a negligible, if not insignificant, detail of his biography, it tries not to claim a Jewish identity for Wittgenstein, but rather to evaluate the effects elicited on his philosophy by (...)

KW is almost universally read as having rejected any account of meaning attributions which takes them to be stating facts or corresponding to facts. In a word, KW is understood as offering (...)

  20. Meta-Ethical Quietism? Wittgenstein, Relaxed Realism, and Countercultures in Meta-Ethics.Farbod Akhlaghi - forthcoming - In Jonathan Beale & Rach Cosker-Rowland (eds.), Wittgenstein and Contemporary Moral Philosophy.
    Ludwig Wittgenstein has often been called a quietist. His work has inspired a rich and varied array of theories in moral philosophy. Some prominent meta-ethicists have also been called quietists, or ‘relaxed’ as opposed to ‘robust’ realists, sometimes with explicit reference to Wittgenstein in attempts to clarify their views. In this chapter, I compare and contrast these groups of theories and draw out their importance for contemporary meta-ethical debate. They represent countercultures to contemporary meta-ethics. That is, they reject in different (...)

It is instructive to have a look at a criticism of these presupositions and I present Wittgenstein as the author who provides such a criticism. I present a development of his view of logical form which went from the thesis of the ineffability of (...)

    In his Remarks on the Foundations of Mathematics, Wittgenstein claims, puzzlingly, that ‘the proof creates a new concept’ (RFM III-41). This paper aims to contribute to clarifying this idea, and to showing how it marks a major break with the traditional conception of proof. Moreover, since the most natural way to understand his claim is open to criticism, a secondary goal of what follows is to offer an interpretation of it that neutralizes the objection. The discussion proceeds by analysing a (...)

    With respect to the metaphysics of infinity, the tendency of standard debates is to either endorse or to deny the reality of ‘the infinite’. But how should we understand the notion of ‘reality’ employed in stating these options? Wittgenstein’s critical strategy shows that the notion is grounded in a confusion: talk of infinity naturally takes hold of one’s imagination due to the sway of verbal pictures and analogies suggested by our words. This is the source of various philosophical pictures that (...)

Nonetheless, it is the aim of this chapter to provide an overview of this unruly theological terrain. It does this by setting out ‘maps’ of the range of positions which Jewish philosophers have taken regarding key aspects of the God-idea. These conceptual maps will cover: (i) how Jewish philosophers have thought of the role and status of conceiving of (...)

    This chapter serves as an opinionated introduction to the problem of convergence (that there is no clear convergence to the truth in philosophy) and the problem of peer disagreement (that disagreement with a peer rationally demands suspending one’s beliefs), and some of the issues they give rise to, namely, philosophical skepticism and progress in philosophy. After introducing both topics and surveying the various positions in the literature we explore the prospects of an alternative, hinge-theoretic account.

    Wittgenstein in his early work viz. Tractatus argued that there is a common, essential, underlying structure that links logic, language and the world. He also argued about the need for an analysis of ordinary language in terms of a perspicuous symbolism that would display a one to one relationship between a proposition and a fact – when both of them are broken down to their simplest components – viz. to atomic propositions and atomic states of affairs. All propositions are ultimately (...)

I seek to align the later philosophy of Wittgenstein with Marx’s 11th thesis on Feuerbach. I advance an unorthodox view interpreting Wittgenstein as an advocate for social and political reform. Wittgenstein’s philosophy encourages us to imagine alternatives and contemplate concrete possibilities for changing the world. The debate operates within the philosophy of education and draws (...)

It is argued that an adequate description of the meaning of expressive moral judgements requires engaging in a grammatical investigation that focuses on three interwoven components within specific language-games. First, the ethical reactions expressed by moral words and the additional purpose they may fulfil. Second, the features of the actions which are bound up with moral words and (...)

    This paper continues my development of philosophy of religion as multi-disciplinary comparative research. An earlier paper, “Wittgenstein and Contemporary Belief-Credence Dualism” compared Wittgensteinian reflections on religious discourse and praxis with B-C dualism as articulated by its leading proponents. While some strong commonalities were elaborated that might help to bridge Continental and Analytic approaches in philosophy of religion, Wittgenstein was found to be a corrective to B-C dualism especially as regards how the psychology and philosophy of epistemic luck/risk applies to doxastic (...)

Besides Wittgenstein’s systematic interests in parallels between music and language, the paper draws on the choice of terminology (such as the comparison of rules to rails) and on Wittgenstein’s own examples of rule-following. More speculatively, the phrasing (...)
