Conceptual engineering involves revising our concepts. It can be pursued as a specific philosophical methodology, but is also common in ordinary, non-philosophical, contexts. How does our capacity for conceptual engineering fit into human cognitive life more broadly? I hold that conceptual engineering is best understood alongside practices of conceptual exploration, examples of which include conceptual supposition (i.e. suppositional reasoning about alternative concepts), and conceptual comparison (i.e. comparisons between possible concept choices). Whereas in conceptual engineering we aim to change the concepts (...) we use, in conceptual exploration, we reason about conceptual possibilities. I approach conceptual exploration via the linguistic tools we use to communicate about concepts, using metalinguistic negotiation, convention-shifting conditionals, and metalinguistic comparatives as my key examples. I present a linguistic framework incorporating conventions that can account for this communication in a unified way. Furthermore, I argue that conceptual exploration helps undermine skepticism about conceptual engineering itself. (shrink)

Assertions about appearances license inferences about the speaker's perceptual experience. For instance, if I assert, 'Tom looks like he's cooking', you will infer both that I am visually acquainted with Tom (what I call the "individual acquaintance inference"), and that I am visually acquainted with evidence that Tom is cooking (what I call the "evidential acquaintance inference"). By contrast, if I assert, 'It looks like Tom is cooking', only the latter inference is licensed. I develop an account of the acquaintance (...) inferences of appearance assertions building on two main previous lines of research: first, the copy raising literature, which has aimed to account for individual acquaintance inferences through the "perceptual source" semantic role; second, the subjectivity literature, which has focused on the status of acquaintance inferences with predicates of personal taste, but hasn't given much attention to the added complexities introduced by appearance language. I begin by developing what I take to be the most empirically-sound version of a perceptual source analysis. I then show how its insights can be maintained, while however taking anything about perception out of the truth conditions of appearance sentences. This, together with the assumption that appearance assertions express experiential attitudes, allows us to capture the acquaintance inferences of bare appearance assertions without making incorrect predictions about the behavior of appearance verbs in embedded environments.

How different neural crest derivatives differentiate in distinct embryonic locations in the vertebrate embryo is an intriguing issue. Many attempts have been made to understand the underlying mechanism of specific pathway choices made by migrating neural crest cells. In this speculative review we suggest a new mechanism for the regulation of neural crest cell migration patterns in avian and mammalian embryos, based on recent progress in understanding the expression and activity of receptor tyrosine kinases during embryogenesis. Distinct subpopulations of crest‐derived (...) cells express specific receptor tyrosine kinases while residing in a migration staging area. We postulate that the differential expression of receptor tyrosine kinases by specific subpopulations of neural crest cells allows them to respond to localized growth factor ligand activity in the embryo. Thus, the migration pathway taken by neural crest subpopulations is determined by their receptor tyrosine kinase response to the differential localization of their cognate ligand. (shrink)

In theoretical work about the language of personal taste, the canonical example is the simple predicate of personal taste, 'tasty'. We can also express the same positive gustatory evaluation with the complex expression, 'taste good'. But there is a challenge for an analysis of 'taste good': While it can be used equivalently with 'tasty', it need not be (for instance, imagine it used by someone who can identify good wines by taste but doesn't enjoy them). This kind of two-faced behavior (...) systematically arises with complex sensory-evaluative predicates, including those with other appearance verbs, such as 'look splendid' and 'sound nice'. I examine two strategies for capturing these different uses: one that posits an ambiguity in appearance verbs, and one that does not. The former is in line with an approach to 'look'-statements prominent in work in philosophy of perception, and I consider how the motivation given in that tradition carries over to the present context. I then show how the data used to support the verbal ambiguity approach can equally be captured on the second strategy, which appeals only to independently-motivated flexibility in adjective meaning. I close by discussing some considerations that are relevant for choosing between the two options. (shrink)

What distinguishes academic administration from administration or managing in business? Rudolph Weingartner, arugues that colleges and universities are founded to serve certain purposes; they are supported by governments and private individuals; and, as professional institutions, they have students, among others, as clients to whom they owe education services in ways analogous to the obligations hospitals have via-à-vis their patients. Academic administration is not just another job of managing, but a calling that importantly assists institutions to carry out their missions.

I argue that Democritus presents a theory of colour in which the predominance of atomic shapes and microstructural arrangements are necessary but not sufficient for colour vision. Focusing primarily on Democritus’ basic colours, I analyse his microstructural account, providing a new analysis of the natural and technological underpinnings of his method of explanation. I argue that the notion of predominance allows Democritus to account for both the variation and the repeatable correspondence of colour perception by setting limits on possible microstructures. (...) This account, however, is complicated by the evidence for a Democritean theory of colour transformation and distorted vision, which arise from a dynamic interplay of features at the level of microstructures and at the level of perception.

This paper offers a critique of ‘powerful knowledge’ – a concept in Education Studies that has been presented as a just basis for school curricula. Powerful knowledge is disciplinary knowledge produced and refined through a process of ‘specialisation’ that usually occurs in universities. Drawing on postcolonial, decolonial and Indigenous studies, we show how powerful knowledge seems to focus on the progressive impulse of modernity while overlooking the ruination of colonial racism. We call on scholars and practitioners working with the powerful (...) knowledge framework to address more fully the hegemonic relations of disciplinary specialisation and its historical connections to colonial-modernity. This, we argue, would enable curriculum knowledge that is ‘powerful’ in its interrogation of racial violence, rather than in its epistemic reproduction of it. (shrink)

This section discusses mostly some unsolved problems. . . .I hope that some mathematicians who are interested in a classification of sets of real numbers, in particular sets with Lebesgue measure zero, will read it and try to find solutions for the problems here outlined.

Democritus' theory of vision combines the notions of images (??????) streaming from objects and air imprints, which gives him the resources to account for the perception of the relative size and distance of objects, not just their characteristics. This perspectival explanation of the visual theory accommodates important but overlooked evidence from Vitruvius. By comparing Democritus' theory with ancient developments in visual representation, my analysis provides a new approach to the evidence of atomist vision. I begin with the process of vision (...) before turning to the Peripatetic objections, showing how a unified theory of vision takes into account all of the ancient testimony and provides possible atomist responses to the criticisms raised against it. I also identify the importance of vision via air imprints as an important metaphor for the conventionality of sensible qualities. Understanding these fundamental issues puts us in a better position to assess Democritus' place in the development of ancient optics and of atomist approaches to sense perception. (shrink)

We present a novel semantic and conversational framework for a class of gradable-like constructions. These include metalinguistic comparatives, like "Ann is more a linguist than a philosopher", as well as metalinguistic equatives, degree modifications, and conditionals. To the extent previous literature discusses such metalinguistic gradability, the focus has been on comparatives. We extend our account of metalinguistic comparatives (Rudolph & Kocurek 2020) to cover a broader range of metalinguistic gradable constructions. On our semantic expressivist view, these all serve in (...) various ways to express speakers' relative commitments to different linguistic interpretations. (shrink)

Faultless disagreement and faultless retraction have been taken to motivate relativism for predicates of personal taste, like ‘tasty’. Less attention has been devoted to the question of what aspect of their meaning underlies this relativist behavior. This paper illustrates these same phenomena with a new category of expressions: appearance predicates, like ‘tastes vegan’ and ‘looks blue’. Appearance predicates and predicates of personal taste both fall into the broader category of experiential predicates. Approaching predicates of personal taste from this angle suggests (...) that their relativist behavior is due to their experience-sensitivity, rather than their evaluative meaning. Furthermore, appearance predicates hold interest beyond what they can teach us about predicates of personal taste. Examination of a variety of uses of appearance predicates reveals that they give rise to relativist behavior for a variety of reasons—including some that apply also to other types of expressions, such as epistemic modals and comparative terms. This paper thus serves both to probe the source of relativist behavior in discourse about personal taste, as well as to map out this kind of behavior in the rich and under-explored discourse about appearances.

We offer a novel account of metalinguistic comparatives, such as 'Al is more wise than clever'. On our view, metalinguistic comparatives express comparative commitments to conventions. Thus, 'Al is more wise than clever' expresses that the speaker has a stronger commitment to a convention on which Al is wise than to a convention on which she is clever. This view avoids problems facing previous approaches to metalinguistic comparatives. It also fits within a broader framework—independently motivated by metalinguistic negotiations and convention-shiftingexpressions— (...) that gives linguistic conventions a role in the semantics.

This article investigates the emergence of the concept of stress in the 1930s and outlines its changing disciplinary and conceptual frames up until 1960. Originally stress was a physiological concept applied to the hormonal regulation of the body under stressful conditions. Correlated closely with chemical research into corticosteroids for more than a decade, the stress concept finally became a topic in cognitive psychology. One reason for this shift of the concept to another discipline was the fact that the hormones previously (...) linked to the stress concept were successfully transferred from laboratory to medical practice and adopted by disciplines such as rheumatology and dermatology. Thus the stress concept was dissociated from its hormonal context and became a handy formula that allowed postindustrial society to conceive of stress as a matter of individual concern. From a physiological phenomenon stress turned into an object of psychological discourse and individual coping strategies. (shrink)

An läßlich der I 00. Wiederkehr des Geburtstages von Ludwig Wittgenstein, dem wohl bedeutendsten Philosophen unseres Jahrhunderts und Namensgeber der veranstaltenden Gesellschaft, wurde das 14. Internationale Symposium in Kirchberg gänzlich unter die programmatische Perspektive einer Neubewertung seiner Philosophie gestellt. Dem Anlasse entsprechend war dieses Symposium das weitaus größte aller bisherigen mit nahezu 600 Teilnehmern und 230 Vorträgen. Nur 138 davon konnten in die Akten des 14. Symposiums aufgenommen werden, dietrotzdieser Auswahl über 1000 Seiten stark wurden. Wegen dieses außerordentlichen Umfangs ist (...) es nötig, die Akten diesmal auf drei Bände aufzuteilen. Der erste Band enthält eingeladene Vorträge, gegliedert nach fünf Themenschw- punkten: Zur Philosophie der Traktatperiode Zur Philosophie von Logik und Mathematik Zur Übergangsperiode der Dreißigerjahre Zur Aufgabe der Philosophie Zur Ethik und Religion. Freilich wäre es eine Übertreibung zu behaupten, daß alle Beiträge im vollen Wortsin ne eine Neubewertung von Wittgensteins Philosophie veranschaulichen. Aber der Ten denz nach exemplifizieren die gesammelten Texte den Stand der gegenwärtigen Wittgen stein-Interpretation sehr deutlich. Waren in den ersten Jahren nach seinem Tode und der Publikation der nachgelassenen Schriften die Bemühungen zunächst auf die sprachphi losophischen Aspekte der Philosophischen Untersuchungen, das Privatsprachenproblem und den Neuerungen nach der Traktatperiode gerichtet, so zeigten sich seit den Siehziger jahren Tendenzen zur Vereinheitlichung. So entstand in den letzten Jahren ein zuneh mend differenzierteres Bild sowohl der Entwicklung von Wittgensteins Philosophie als auch der Rolle von Logik, Bedeutung und Bezug sprachlicher Zeichen im Gesamtkonte.
