Re-Engineering the Concept of Understanding for AI

With Pierre Beckmann.

Argues that the concept of understanding needs to be re-engineered for artificial cognition in a way that is empirically informed by mechanistic interpretability research and theoretically informed by a grasp of the functions of the concept.

The Invented Inventor: Adapting Intellectual Property to Generative AI

Under review

As AI increasingly drives discovery, the concept of inventor faces severe strain. Recent judicial decisions, such as the Swiss Federal Administrative Court’s 2025 DABUS ruling, expose a deepening tension: courts demand intellectual creation by a natural person even as human contributions to AI-assisted discovery become increasingly nominal. This paper approaches the resulting tension from the standpoint of political philosophy rather than jurisprudence: the strain AI places on the concept of inventorship is too fundamental to be resolved by interpretative methods taking existing conceptual architectures for granted. Inspired by Hume’s genealogy of property, the paper reconstructs the historical “need matrices” that forged the concept of inventorship, tracing its evolution from Venetian guild economics through Romantic genius ideology to corporate R&D. This reveals the concept to be an overburdened bundle serving four social functions: incentivising innovation, disseminating knowledge, legitimating monopolies, and resolving priority disputes. It also clarifies the mismatch between the concept and the emerging realities of AI-driven discovery. To resolve this mismatch, we must disaggregate the concept of inventorship and develop specialised conceptual resources for each of these functions. If we invented the notion of inventor to perform certain functions, we can reinvent it to perform them better.

Conceptual Engineering

In Metzler Handbuch Analytische Philosophie. Hans-Johann Glock, Christoph Pfisterer and Stefan Roski (eds.). Stuttgart: Metzler.

Conceptual engineering reorients analytic philosophy from the descriptive analysis of existing concepts to the normative task of assessing and improving representational devices to better serve our theoretical and practical purposes. This entry traces the method’s intellectual genealogy from Rudolf Carnap’s explication and pragmatist reconstruction to the contemporary ‘functionalist’ and ‘ameliorative’ frameworks championed by Haslanger, Simion, and Kelp. It concludes by examining the discipline’s current ‘applied turn,’ surveying how recent scholarship from 2024 to 2026 has operationalized these methods to address concrete problems in social ontology, artificial intelligence, and medicine.

Explication or Amelioration? Carnapian Clarification as the Normative Basis for Conceptual Engineering

The Monist. Special issue on Explication and Conceptual Engineering.

As conceptual engineering fractures into explication pursuing exactness and amelioration pursuing justice, the field risks losing its focus. I argue that unifying these projects requires retrieving a crucial insight from Rudolf Carnap: that attempts to improve concepts must start with the preliminary stage of practical clarification. However, Carnap’s account of clarification in terms of predictive proficiency remains normatively inert and biased towards exactness. I expand it into a normative diagnosis of the needs underpinning a concept’s inferential structure. This reveals whether properties like vagueness are flaws that need fixing or features worth preserving.

Law as a Test of Conceptual Strength

In Bernard Williams on Law and Jurisprudence: From Agency and Responsibility to Methodology. Veronica Rodriguez-Blanco, Daniel Peixoto Murata and Julieta Rabanos (eds.). Oxford: Hart. In Press. https://philpapers.org/archive/QUELAA.pdf

Reads Williams’s “What Has Philosophy to Learn from Tort Law?” as a radicalization of Austin’s insight that tort law is where the concepts of common sense are truly put on trial. Identifies seven features of tort litigation that subject notions like fault, intention, negligence, and voluntariness to extraordinary pressure. Explains, by contrasting tort law with criminal law, how differences in evidential standards, case profiles, and doctrines of strict liability display both the power and the weak points of our responsibility-tracking concepts.

Reasons of Love and Conceptual Good-for-Nothings

In Themes from Susan Wolf. Michael Frauchiger and Markus Stepanians (eds.). Berlin: De Gruyter. In Press.

Appealing to the instrumentality of concepts raises the worry of yielding the “wrong kind of reasons.” Drawing on Susan Wolf’s work on “reasons of love,” I argue this worry is misplaced. I further explore Wolf’s notion of “valuable good-for-nothings” to demonstrate how non-instrumental values ultimately reinforce the importance of reasons of love in concept use.

The Ethics of Conceptualization: Tailoring Thought and Language to Need

Oxford: Oxford University Press. 2025. doi:10.1093/9780198926283.001.0001

Philosophy strives to give us a firmer hold on our concepts. But what about their hold on us? Why place ourselves under the sway of a concept and grant it the authority to shape our thought and conduct? Another conceptualization would carry different implications. What makes one way of thinking better than another? This book develops a framework for concept appraisal. Its guiding idea is that to question the authority of concepts is to ask for reasons of a special kind: reasons for concept use, which tell us which concepts to adopt, adhere to, or abandon, thereby shoring up—or undercutting—the reasons for action and belief that guide our deliberations. Traditionally, reasons for concept use have been sought either in timeless rational foundations or in concepts’ inherent virtues, such as precision and consistency. Against this, the book advances two main claims: that we find reasons for concept use in the conceptual needs we discover when we critically distance ourselves from a concept by viewing it from the autoethnographic stance; and that sometimes, concepts that conflict, or exhibit other vices such as vagueness or superficiality, are just what we need. By considering not what concepts are absolutely best, but what concepts we now need, we can reconcile ourselves to the contingency of our concepts, determine the proper place of efforts to tidy up thought, and adjudicate between competing conceptions of things—even things as contested as liberty or free will. A needs-based approach separates helpful clarification from hobbling tidy-mindedness, and authoritative definition from conceptual gerrymandering.

The Dworkin–Williams Debate: Liberty, Conceptual Integrity, and Tragic Conflict in Politics

Philosophy and Phenomenological Research 109 (1): 3–29. 2024. doi:10.1111/phpr.13002

By reconstructing the little-known Dworkin-Williams debate over whether political concepts like liberty and equality can and should be reconciled to avoid conflict, the article explores the nature of political values, the limits of philosophical intervention in politics, the challenge of pluralism, and the conditions for political legitimacy in the face of inevitable conflict and loss.

Virtues, Rights, or Consequences? Mapping the Way for Conceptual Ethics

Studia Philosophica: The Swiss Journal of Philosophy 83 (1): 9–22. 2024. doi:10.24894/StPh-en.2024.83002

Maps out the ways in which moral and political reflection on which concepts to use might take its cue from virtue-ethical, deontological, and consequentialist traditions, flagging the main difficulties facing each approach.

Conceptual Engineering and the Politics of Implementation

Pacific Philosophical Quarterly 103 (3): 670–691. 2022. With Friedemann Bieber. doi:10.1111/papq.12394

Argues that how much control we have over conceptual change is itself something we can control, and while some domains require the institutionalization of the power to enforce conceptual innovations, because there are strong practical pressures to coordinate on a single harmonized technical terminology, there are also liberal and democratic rationales for making conceptual engineering hard to implement by default.

Function-Based Conceptual Engineering and the Authority Problem

Mind 131 (524): 1247–1278. 2022. doi:10.1093/mind/fzac028

Identifies a central problem for conceptual engineering—the problem of establishing the authority of engineered concepts—and argues that this problem cannot generally be solved by appealing to increased precision, consistency, or other theoretical virtues. Solving the problem requires engineering to take a functional turn and attend to the functions of concepts. This also helps us alleviate Strawsonian worries about changes of topic.

Nietzsche’s Conceptual Ethics

Inquiry 66 (7): 1335–1364. Proceedings of the International Society of Nietzsche Studies. 2023. doi:10.1080/0020174X.2022.2164049

While Nietzsche appears to engage in two seemingly contrary modes of concept evaluation—one looks to concepts’ effects, the other to what concepts express—this article offers an account of the expressive character of concepts which unifies these two modes and yields a powerful approach to practical reflection on which concepts to use.

Choosing Values? Williams contra Nietzsche

The Philosophical Quarterly 71 (2): 286–307. 2021. doi:10.1093/pq/pqaa026

Highlights enduring epistemic and metaphysical difficulties for any project of evaluating and improving the values we live by, including contemporary work in conceptual ethics and engineering, and argues that attempts to sidestep these difficulties fall prey to “Saint-Just’s illusion”—the mistake of believing that a set of values from one political context can be successfully transplanted into a different political context.

Left Wittgensteinianism

European Journal of Philosophy 29 (4): 758–77. 2021. With Damian Cueni. doi:10.1111/ejop.12603

Focusing on the social and political conceptual practices that Wittgenstein neglected, the paper presents a novel, more dynamic interpretation of Wittgenstein’s model of conceptual change, on which conceptual change becomes intelligible not just as a brute, exogenous imposition on rational discourse, but as endogenous and reason-driven. This counters the socially conservative tendencies of existing interpretations and renders intelligible the possibility of radical critique within a Wittgensteinian framework.

The Practical Origins of Ideas: Genealogy as Conceptual Reverse-Engineering

Oxford: Oxford University Press. 2021. doi:10.1093/oso/9780198868705.001.0001

Why did such highly abstract ideas as truth, knowledge, or justice become so important to us? What was the point of coming to think in these terms? In The Practical Origins of Ideas, Matthieu Queloz presents a philosophical method designed to answer such questions: the method of pragmatic genealogy. Pragmatic genealogies are partly fictional, partly historical narratives exploring what might have driven us to develop certain ideas in order to discover what these do for us. The book uncovers an under-appreciated tradition of pragmatic genealogy which cuts across the analytic–continental divide, running from the state-of-nature stories of David Hume and the early genealogies of Friedrich Nietzsche to recent work in analytic philosophy by Edward Craig, Bernard Williams, and Miranda Fricker. However, these genealogies combine fictionalizing and historicizing in ways that even philosophers sympathetic to the use of state-of-nature fictions or real history have found puzzling. To make sense of why both fictionalizing and historicizing are called for, the book offers a systematic account of pragmatic genealogies as dynamic models serving to reverse-engineer the points of ideas in relation not only to near-universal human needs, but also to socio-historically situated needs. This allows the method to offer us explanation without reduction and to help us understand what led our ideas to shed the traces of their practical origins. Far from being normatively inert, moreover, pragmatic genealogy can affect the space of reasons, guiding attempts to improve our conceptual repertoire by helping us determine whether and when our ideas are worth having.

On Ordered Pluralism

Australasian Philosophical Review 3 (3): 305–11. 2019. doi:10.1080/24740500.2020.1859234

Beginning with the debate concerning “moral justice forgiveness” and “gifted” forgiveness, this paper critically examines Miranda Fricker’s method for ordering plural conceptions of a practice. It argues that the selection of a paradigm case, such as “moral justice forgiveness,” is not absolute, but depends on which functional aspect of the practice one wishes to explain.

The Points of Concepts: Their Types, Tensions, and Connections

Canadian Journal of Philosophy 49 (8): 1122–1145. 2019. doi:10.1080/00455091.2019.1584940

By distinguishing four senses in which concepts might be said to have a “point,” this paper resolves the tension between the ambition of point-based explanations to be informative and the claim—central to Dummett’s philosophy of language, but also to the literature on thick concepts—that mastering concepts already requires grasping their point.
