Judgements, facts and propositions: theories of truth in Russell, Wittgenstein and Ramsey.Colin Johnston &Peter Sullivan -2018 - In Michael Glanzberg,The Oxford Handbook of Truth. Oxford, United Kingdom: Oxford University Press. pp. 150-192.detailsIn 'On the nature of truth and falsehood' Russell offers both a multiple relation theory of judgment and a correspondence theory of truth. It has been a prevailing understanding of the Tractatus that Wittgenstein rejects Russell’s multiple relation idea but endorses the correspondence theory. Ramsey took the opposite view. In his 'Facts and Propositions', Ramsey endorses Russell’s multiple relation idea, rejects the correspondence theory, and then asserts that these moves are both due to Wittgenstein. This chapter will argue that Ramsey’s (...) ascriptions are both correct. The extent of the agreement between Ramsey and Wittgenstein will be argued, moreover, to count definitively against standard understandings of Ramsey as a redundancy theorist of truth. Wittgenstein is no correspondence theorist and Ramsey is no redundancy theorist; rather, both philosophers offer identity theories of truth. (shrink)
Frege, the self-consciousness of judgement, and the indefinability of truth.Colin Johnston -2021 -British Journal for the History of Philosophy 29 (6):1124-1143.detailsABSTRACT Frege characterizes judgement as the acknowledgement of the truth of a thought, appearing thereby to rule out false judgement. First in this paper I explain Frege’s characterization so that it does not have this consequence. Frege is not saying that for a subject S to judge that p is for S to acknowledge the truth of the thought that p. Rather, he is articulating judgement’s nature within self-consciousness. From within, to judge means to acknowledge a truth. Second, I suggest (...) that this articulation is centrally operative in Frege’s argument for the indefinability of truth. As Frege argues, it follows from judgement’s self-consciousness that truth is indefinable. (shrink)
Judgment and the identity theory of truth.Colin Johnston -2013 -Philosophical Studies 166 (2):381-397.detailsThe identity theory of truth takes on different forms depending on whether it is combined with a dual relation or a multiple relation theory of judgment. This paper argues that there are two significant problems for the dual relation identity theorist regarding thought’s answerability to reality, neither of which takes a grip on the multiple relation identity theory.
The Unity of a Tractarian Fact.Colin Johnston -2007 -Synthese 156 (2):231-251.detailsIt is not immediately clear from Wittgenstein’s Tractatus how to connect his idea there of an object with the logical ontologies of Frege and Russell. Toward clarification on this matter, this paper compares Russell’s and Wittgenstein’s versions of the thesis of an atomic fact that it is a complex composition. The claim arrived at is that whilst Russell (at times at least) has one particular of the elements of a fact – the relation – responsible for the unity of the (...) whole, for Wittgenstein the unity of a fact is the product of copulative powers inherent in all its elements. All kinds of constituents of Tractarian facts – all kinds (forms) of object – are, to use Fregean terminology, unsaturated. (shrink)
Tractarian objects and logical categories.Colin Johnston -2009 -Synthese 167 (1):145 - 161.detailsIt has been much debated whether Tractarian objects are what Russell would have called particulars or whether they include also properties and relations. This paper claims that the debate is misguided: there is no logical category such that Wittgenstein intended the reader of the Tractatus to understand his objects either as providing examples of or as not providing examples of that category. This is not to say that Wittgenstein set himself against the very idea of a logical category: quite the (...) contrary. However, where Russell presents his logical variety of particulars and the various types of universal, and Frege presents his of objects and the various types of function, Wittgenstein denies the propriety of such a priori expositions. Wittgenstein envisages a variety of logical types of entity but insists that the nature of these types is something to be discovered only through analysis. (shrink)
Symbols in Wittgenstein's Tractatus.Colin Johnston -2007 -European Journal of Philosophy 15 (3):367-394.detailsThis paper is concerned with the status of a symbol in Wittgenstein’s Tractatus. It is claimed in the first section that a Tractarian symbol, whilst essentially a syntactic entity to be distinguished from the mark or sound that is its sign, bears its semantic significance only inessentially. In the second and third sections I pursue this point of exegesis through the Tractarian discussions of nonsense and the context principle respectively. The final section of the paper places the forgoing work in (...) a secondary context, addressing in particular a debate regarding the realism of the Tractatus. (shrink)
Wittgenstein and Frege on Negation and Denial.Colin Johnston -2024 -Journal for the History of Analytical Philosophy 12 (3).detailsFrege maintains that there are not two distinct acts, assertion and denial; rather, denying p is one and the same as asserting not-p. Wittgenstein appears not to recognise this identity in Frege, attributing to him the contrary view that a proposition may have one of two verbs, "is true" or "is false". This paper explains Wittgenstein’s attribution as a consequence of Frege’s treatment of content as theoretically prior to the act of judgment. Where content is prior to judgment, the denial (...) of p—what is rejected in asserting p—is distinct from the assertion of not-p. Wittgenstein’s own embrace of Frege’s identity is then considered, an embrace explained in part by his repudiation of Frege’s theoretical order. (shrink)
Conflicting Rules and Paradox.Colin Johnston -2014 -Philosophy and Phenomenological Research 88 (2):410-433.detailsFirst paragraph: This paper seeks to understand various paradoxes as cases of conflicting rules. In particular, the ambition is to outline a new perspective on and response to the Liar -- though it will take us a while to get that far. We begin in Section 1 with an account of simple rule confliction. Section 2 then brings this account to bear on a paradox, the Secretary Liberation Paradox, which is readily seen to involve conflicting rules. Finally in Section 3 (...) I suggest that the Liar can also be seen as a case of rule confliction, and outline briefly how that perspective provides for Liar arguments to be blocked. (shrink)
Russell, Wittgenstein, and synthesis in thought.Colin Johnston -2012 - In José L. Zalabardo,Wittgenstein's Early Philosophy. Oxford, GB: Oxford University Press. pp. 15.detailsWittgenstein held that Russell’s multiple relation theory of judgment fails to explain an atomic judgment’s representation of entities as combined. He demonstrated this failure as follows. Under the multiple relation theory, an atomic judgment is a complex whose relating relation is judgment, the universal, and whose terms include the entities the judgment represents as combined. Taking such a complex we may arrive through the substitution of constituents at a complex whose relating relation is again judgment but whose terms do not (...) include entities which are logically suited for combination. This second judgment complex will not represent any of its terms as combined, for entities that are logically uncombinable are unrepresentable as combined. Russell’s theory does not, however, explain how the original judgment differs from the complex arrived at by the substitution of constituents such that the former but not the latter represents certain of its terms as combined.

Temporal Passage and Being in Time.Colin Johnston -2021 - In Adrian Haddock & Rachael Wiseman,The Anscombean Mind. New York, NY: Routledge. pp. 154-173.detailsThis paper argues that the passage of time cannot be understood in a certain ‘objective’ manner: it is not something comprehensible as from no one and nowhen by means of generalizations over times, properties, subjects, events etc. This does not mean, however, that its reality should be denied, that we should lower our sights to explaining instead ‘the experience of time as passing’. Rather, time’s passage is to be elaborated within a metaphysics of time of a rather different kind, one (...) which might be presented as an articulation of being in time. (shrink)
The Picture Theory.Colin Johnston -2017 - In Hans-Johann Glock & John Hyman,A Companion to Wittgenstein. Chichester, West Sussex, UK: Wiley-Blackwell. pp. 141–158.detailsAn elementary proposition, Wittgenstein holds, is a combination of names. Each name stands for an object. And the proposition represents that the objects are *so* combined: that is, that they are combined as their names are combined in the proposition. This essay on Wittgenstein's picture theory focuses on this identity: in what manner are the proposition and its sense combinations of the same kind? Answering this question, we consider that the Tractatus makes no distinction between sense and fact (so Wittgenstein (...) rejects the correspondence theory of truth), and that a proposition is for Wittgenstein the *expression* of its sense. (shrink)
Solipsism and the Graspability of Fact.Colin Johnston -2019 - In Hanne Appelqvist,Wittgenstein and the Limits of Language. New York: Routledge.detailsWittgenstein’s Tractarian discussion of solipsism opens with the claim that ‘[t]he limits of my language mean the limits of the world’ (TLP 5.6.) According to this paper, Wittgenstein expresses here a thought that the subject makes no sense of her thinking having content going beyond in kind that which she possesses in thinking. What the subject possesses in thinking is furthermore a truth or falsity, so that the idea is ruled out of truth-independent substance to the world. At the same (...) time, however, thinking is an act of the subject given to her only as such – only as something she does, and so only as a determination of herself. Truth is not therefore independent of the subject; rather, as Wittgenstein puts it, ‘the world is my world’ (TLP 5.62). This conclusion threatens an idealism under which the nature of truth is explained by reference to that of the subject; objectivity is grounded in a deeper subjectivity. This threat is deflected by the recognition that the solipsist’s subject is an essentially undistanceable ‘I’ without content or character, so that ‘solipsism strictly carried out coincides with pure realism’ (TLP 5.64).

Wittgenstein on representability and possibility.Colin Johnston -2017 - In Sandra Lapointe & Christopher Pincock,Innovations in the History of Analytical Philosophy. London, United Kingdom: Palgrave-Macmillan. pp. 127-147.detailsIt is a central commitment of the Tractatus that “it is impossible to judge a nonsense” (§5.5422). This essay seeks to understand the ground of this commitment in Wittgenstein’s thought. To this end, various interpretations of the Tractatus on ‘the relation between language and reality’ are considered, with each position assessed for the understanding it provides of the stance against nonsense. Having rejected as inadequate various realist readings, and then also an idealist reading, the essay recommends a view on which (...) language and reality are internally bound together in the notion of truth. Where a fact is precisely a truth condition, and so something to be represented, a proposition (a judgment) is precisely the representation of such a fact, the representation of a truth condition.

Assertion, saying, and propositional complexity in Wittgenstein's Tractatus.Colin Johnston -2011 - In Oskari Kuusela & Marie McGinn,The Oxford Handbook of Wittgenstein. Oxford, England: Oxford University Press.detailsWittgenstein responds in his Notes on Logic to a discussion of Russell's Principles of Mathematics concerning assertion. Russell writes: "It is plain that, if I may be allowed to use the word assertion in a non-psychological sense, the proposition "p implies q" asserts an implication, though it does not assert p or q. The p and the q which enter into this proposition are not strictly the same as the p or the q which are separate propositions." (PoM p35) Wittgenstein (...) replies: "Assertion is merely psychological. In not-p, p is exactly the same as if it stands alone; this point is absolutely fundamental." (NB p95) Wittgenstein's response is intriguing, not least because of the centrality to his Tractatus of the idea that a proposition says something. This paper will examine that idea, distinguishing it from 'merely psychological' assertion, and explore in this context how we should understand the occurrence of a Tractarian proposition within another.

Frege on Syntax, Ontology, and Truth's Pride of Place.Colin Johnston -2018 -European Journal of Philosophy 26 (1):569-588.detailsFrege's strict alignment between his syntactic and ontological categories is not, as is commonly assumed, some kind of a philosophical thesis. There is no thesis that proper names refer only to objects, say, or that what refers to an object is a proper name. Rather, the alignment of categories is internal to Frege's conception of what syntax and ontology are. To understand this, we need to recognise the pride of place Frege assigns within his theorising to the notion of truth. (...) For both language and the world, the Fregean categories are logical categories, categories, that is, of truth. The elaboration of this point makes clear the incoherence of supposing that they might not align. (shrink)
Zalabardo on Semantic Unity and Metaphysical Unity.Colin Johnston -2018 -Australasian Philosophical Review 2 (3):321-326.detailsABSTRACTZalabardo argues that the Tractatus makes an important contribution towards explaining how a representation doesn¹t merely introduce various objects, but furthermore represents them as comb...
The Determination of Form by Syntactic Employment: a Model and a Difficulty.Colin Johnston -2008 -Contributions of the Austrian Ludwig Wittgenstein Society 16:156-158.detailsThis paper develops a model for understanding the Tractarian doctrine that a sign insyntactic use determines a form. This doctrine is found to be in tension withWittgenstein's agnosticism with regard to forms of reality.
