◘ Talk by Paul-Mikhail Catapang Podosky (NYU Shanghai): Talking Real and True? The Politics of Race and Gender Classification

Date/Time: May 19th 9am HK

Abstract. I argue that neither metaphysics nor semantics ought to constrain our social kind classificatory practices with race and gender terms, at least in many ordinary contexts. Unlike Robin Dembroff (2021), who argues that we needn’t track extant social kinds with our classifications under conditions of ontological oppression, I maintain that there is a more fundamental issue: meeting the requirements of tracking social kinds, or even tracking the meanings of social kind terms, is simply too epistemically demanding. Granting that ought implies can, even in the epistemic domain, this means that epistemic reasons (alone) cannot normatively govern our classificatory practices with race and gender terms. This allows us to focus more carefully on the reasons that ought to motivate classification; reasons that are sensitive to the lived experience of marginalized folk.

◘ Talk by Laura Schroeter (Melbourne): Three Strands in Sex/Gender Concepts (joint work with François Schroeter)

Date/Time: 16 February 2022, 4pm HK

Abstract: Cognitive, social and developmental psychologists have amassed a wealth of data about the complex patterns of understanding associated with sex/gender terms like ‘woman’ and ‘man’. We focus on three core strands in the conceptual understanding of the term ‘woman’: (1) biological sex, (2) social role, and (3) affiliation (identifying as a member of the class ‘woman’ or ‘man’). In the recent philosophical literature, many theorists have privileged one of these three core strands to argue that ‘woman’ has a univocal reference – a biological kind, a social class, or an affiliative identity kind. We argue against these univocalist approaches and suggest that ordinary sex/gender concepts – and the words used to express them – should be understood as having complex meanings that may be sharpened by context. We contrast our approach with family resemblance interpretations (Stoljar) and standard contextualist proposals (Saul, Diaz-Leon). We draw on the literature on polysemy to show that the complexity of our sex/gender concepts need not lead to confusion or breakdowns in communication.

◘ Talk by Xindi Ye (Hong Kong): Topic continuity and context-sensitivity

Abstract. Plunkett & McPherson (2021) propose a contextualist semantics of ‘topic continuity’: dimensions of continuity are built into the character of ‘topic continuity’, while content is fixed by features of the conversational context. The result is a gradable, multidimensional expression. This talk aims to clarify features of the proposed semantics and investigate their consequences on evaluative discussions about the topic continuity of conceptual engineering proposals. On the basis of foregoing considerations, I argue that Plunkett & McPherson’s proposed semantics cannot do the work they want it to do.

◘ Talk by Matti Eklund (Uppsala): Conceptual Engineering and Conceptual Advances

Date/Time: November 24, 2021, 5pm HK time

Via Zoom.

Abstract. In the talk I focus on conceptual engineering as conceptual innovation. First, I provide a motivation for taking this aspect of conceptual engineering to be significant. Then I turn to three specific things. I present an example of attempted conceptual innovation at work (this has to do with independent work on alien languages). I show how, even when “conceptual innovation” is discussed in texts on conceptual engineering (examples: Deutsch, Chalmers) what ends up being discussed is arguably something else. Then I discuss what we should take genuine conceptual innovation to amount to.

◘ Talk by Derek Ball (St Andrews): Metasemantics and Free Speech

Date/Time: September 30, 2021, 4pm HK time

Abstract. Hume wrote, “We cannot form to ourselves a just idea of the taste of a pine-apple, without having actually tasted it”. Putnam claimed that brains in vats could not entertain thoughts about the external world, since thinking such thoughts requires genuine contact with the world one is thinking about. These are claims about how one’s circumstances constrain what one can think — what contents one can entertain. This talk aims to develop the notion of a content constraint, and to relate this notion to issues of free speech. A leading idea is that free speech requires adequate conceptual and linguistic resources, and that this requirement can motivate actions designed to avoid content constraints (including constraints that might be caused by the actions of other speakers).

◘ Talk by Sarah Sawyer (Sussex): Concept Pluralism in Conceptual Engineering

Date/Time: Friday April 16th, 5pm Hong Kong Time

Via Zoom: contact Matthew McKeever at if you’d like to attend.

Abstract. In this talk, I will argue that an adequate meta-semantic framework capable of accommodating the range of projects currently identified as projects in conceptual engineering must be sensitive to the fact that concepts (and hence projects relating to them) fall into distinct kinds. Concepts can vary, I will argue, with respect to their direction of determination, their modal range, and their temporal range. Acknowledging such variations yields a preliminary taxonomy of concepts and generates a meta-semantic framework that allows us both to accommodate the full range of cases and to identify a proper subset of concepts for special ameliorative consideration. Ignoring such variations, in contrast, leads to a restricted meta-semantic framework that accommodates only a subset of the particular projects while generating implausible accounts of others.

◘ Talk by Una Stojnić (Princeton): Nonnegotiable Meanings: Communication, Ignorance, and Metalinguistic Negotiation

Date/Time: Friday, March 26th, 9am Hong Kong Time

Via Zoom: contact Matthew McKeever at if you’d like to attend.

Abstract. A piece of received wisdom among philosophers is that successful communication requires shared content. A speaker can convey to an audience a desire for water by uttering “I want water” just in case both can coordinate on a shared content—that the speaker desires water. Another piece of received wisdom emphasizes that competent speakers can fail to know, and often make errors about, the meanings of expressions without disrupting linguistic usage (Burge, 1979; Kripke, 1980; Putnam 1975). What allows them to do so is that they are situated in a network of causal/social/historical connections, to which they defer in linguistic usage. Deferential Network Models were introduced to sidestep any clash between successful usage and “arguments from ignorance and error” (Devitt and Sterelny, 1999). But, given potential ignorance, how can agents coordinate on substantive shared information successful communication presumes? How is communication possible in a world of deference?
One reaction is to argue that little antecedent semantic knowledge is needed since we can coordinate on meanings on the fly. Some argue that meanings are dynamic, i.e., constantly changing, and potentially negotiated by members of a linguistic community even during a single conversation (Armstrong, 2016, Cappelen, 2018, Carston 2002, Davidson, 1986, Haslanger 2012; 2018, Ludlow 2008, 2014, Plunkett and Sundell 2013, i.a.). We, however, argue that given the practice of linguistic deference, meanings are non-negotiable, i.e., are not dynamic. Meta-linguistic negotiation can neither change word meaning nor secure a mutually shared content presupposed by communication. Indeed, accounts of meta-linguistic negotiation are unsuccessful in part because they already assume coordination on shared content. In response, one can either, deny that there is widespread ignorance and error, and so, a need for deference, or deny that communication requires a non-trivial mutual grasp of shared content. But either option carries a cost.

◘ Talk by Amie Thomasson (Dartmouth): How should we think about linguistic function?

Date/Time: Monday, March 22nd, 9pm Hong Kong Time

Abstract. Talk of the functions of words or concepts has played a central role in conceptual engineering and in other philosophical projects. But what can we mean by ‘functions’ here, and how can we determine what those functions are? Some have expressed skepticism that we can make any good sense of the idea of function as applied to concepts or words. And this is a fair worry to which we ought to be responsive. In this paper I argue that the idea that parts of language (or concepts) have functions is not hopeless, nor are we limited to saying that the function of a concept (or term) F is just ‘to pick out the Fs’. I will try to show how we can get help in understanding and identifying linguistic functions from work in systemic functional linguistics. This in turn enables us to make progress in determining how we should not, and how we should, come to think about function in language, in ways that matter for conceptual engineering and other projects in philosophy.

CLHK’s Inaugural Talk: Topic Continuity in Conceptual Ethics and Beyond

Talk by David Plunkett (Dartmouth) and Tristram McPherson (OSU).

Date/Time: Friday March 5th, 9am Hong Kong Time.

Via Zoom: contact Matthew McKeever at if you’d like to attend.

Abstract. One important activity in conceptual ethics and conceptual engineering involves proposing to associate a new intension with an existing lexical item. Many philosophers think that one important way to evaluate such a proposal concerns whether it preserves the “topic” picked out the existing lexical item, and several have offered competing proposals concerning what is required for topic continuity. Our paper does two things. First, we distinguish the descriptive question of what is required for “topic continuity” as we currently understand it, from the conceptual ethics question of how it would be best for conceptual ethicists to use ‘topic continuity’ in evaluating their projects. Second, we motivate and provide a context-sensitive answer to the conceptual ethics question. This answer is motivated by the idea that there are several distinct considerations that we can care about in thinking about topic continuity, and how best to weigh them against each other can vary from context to context. We conclude by locating our account in a broader way of thinking about topic across a range of inquiries.
