Ontology of Concepts

Many philosophers have recently become interested in conceptual engineering, or the activity of producing better conceptual schemes in human populations. But few, if any, are asking the question: what would it mean for actual human agents to possess the social authority to modify a conceptual scheme in this way? This paper argues for a deontological approach to conceptual engineering, wherein we have to secure social authority qua engineers before attempting to modify social concepts. I show that the dominant, consequentialist conception (...) of engineering violates basic rights that concept-users have, particularly over their own identity-constituting concepts. Using examples from the philosophy of race and sexuality, I show that conceptual engineers cannot authoritatively modify social concepts if they employ consequentialist reasoning about those concepts.

When asked which of our concepts are normative concepts, metaethicists would be quick to list such concepts as GOOD, OUGHT, and REASON. When asked why such concepts belong on the list, metaethicists would be much slower to respond. Matti Eklund is a notable exception. In his recent book, Choosing Normative Concepts, Eklund argues by elimination for “the Normative Role view” that normative concepts are normative in virtue of having a “normative role” or being “used normatively”. One view that Eklund aims (...) to eliminate is “the Metaphysical view” that normative concepts are normative in virtue of referring to normative properties. In addition to arguing that Eklund’s objection looks doubtful by its own lights, we argue that there are several plausible versions of the Metaphysical view that Eklund doesn’t eliminate, defending various claims about normative concepts and their relationships to deliberation, competence, reference, and possession along the way.

Abilitism is an approach to the metaphysics of concepts according to which each concept consists of a managing cognitive ability coordinating other abilities (cognitive and non-cognitive) and a set of subordinate abilities associated with this managing ability. As I argue here, if we accept the abilitist approach, we can efficiently solve such puzzles in the metaphysics of concepts as the partial possession problem, the concept pluralism problem, etc. However, there are some possible objections to abilitism, concerning the abilitist explanation of (...) compositional properties of concepts, knowledge-that, an extension/intension of concepts, and the idea that concepts are constituents of thought. As I demonstrate here, these objections can be answered. (shrink)

Ontologies are some of the most central constructs in today's large plethora of knowledge technologies, namely in the context of the semantic web. As their coinage indicates, they are direct heirs to the ontological investigations in the long Western philosophical tradition, but it is not easy to make bridges between them. Contemporary ontological commitments often take causality as a central aspect for the ur-segregation of entities, especially in scientific upper ontologies; theories of causality and philosophical ontological investigations often go hand-in-hand, (...) and were essentially inseparable in medieval thought. This constitutes the foundation for a bridge, and this article analyzes the causality-based ontology of the late medieval philosopher Dietrich of Freiberg from the viewpoint of today's upper-ontology engineering. In this bridging attempt, it offers a translation into English of the first part of Dietrich's De origine (abbreviated title) that is a compromise between traditional scholarly translations of medieval Latin philosophical texts and contemporary ontology.

Dennett elabora una concepción del “yo” entendido como un centro de gravedad narrativo. Uno de los obstáculos principales para valorar esta propuesta radica en que resulta dificultoso entender cuál es la naturaleza del concepto dennettiano de “yo”: concretamente, cuáles son los compromisos ontológicos y epistemológicos que cabe atribuir al fenómeno en cuestión. En este artículo defendemos que el mejor modo de realizar una reconstrucción interpretativa de su noción de “yo” es apelando a la distinción elaborada por Reichenbach entre tres clases (...) de entidades, Concreta,a e Illata, y entendiendo a los centros de gravedad narrativos como un caso de Abstracta reichenbachiano. Sostenemos que resulta pertinente e iluminador entender los centros de gravedad narrativos como Abstracta en el sentido de Reichenbach, apoyándonos en que: i) aunque no la aplica directamente al problema de la naturaleza del “yo”, Dennett sí emplea la distinción de Reichenbach en otras partes de su obra; ii) Dennett traza explícitamente una analogía del “yo” con los centros de gravedad que son, justamente, uno de sus ejemplos de Abstracta; iii) este modo de entender al “yo” permite dar sentido y entender mejor ciertos aspectos de la teoría narrativista dennettiana. Además de permitirnos clarificar las metáforas empleadas por Dennett en la elaboración de su teoría narrativa, dicha elucidación conceptual permite comprender mejor la distinción entre las tres clases de psicología intencional trazada por Dennett y es útil para sugerir a cuál de estos tres tipos pertenece el concepto de “yo”. Dennett's theory of personal identity argues that the “self” is no more than a center of narrative gravity. One of the main hurdles to assessing this proposal lies in the fact that it is difficult to understand what the nature of Dennett's concept of "self" is; specifically, what are the ontological and epistemological commitments that can be attributed to the phenomenon in question. In this article, we claim that the best way to make an interpretative reconstruction of his notion of "self" is appealing to the distinction elaborated by Reichenbach between three classes of entities, Concreta, Abstracta, and Illata, and understanding the narrative centers of gravity as a case of Reichenbachian Abstracta. We defend that understanding the narrative centers of gravity as Abstracta in the sense of Reichenbach is pertinent and illuminating given that: i) although he does not apply it directly to the problem of the nature of the "self", Dennett does use Reichenbach's distinction in other parts of his work; ii) Dennett explicitly draws an analogy of the "self" with the centers of gravity that are, precisely, one of his examples of Abstracta; iii) this way of understanding the "self" allows us to give sense and better understand certain aspects of Dennett’s narrative theory. Besides allowing us to clarify the metaphors used by Dennett in the elaboration of his narrative theory, such conceptual elucidation allows us to better understand the distinction between the three classes of intentional psychology drawn by Dennett (1987) and is useful in suggesting to which of these three types the concept of "self" belongs.

A concept is traditionally defined via the necessary and sufficient conditions that clearly determine its extension. By contrast, cognitive views of concepts intend to account for empirical data that show that categorisation under a concept presents typicality effects and a certain degree of indeterminacy. We propose a formal language to compactly represent concepts by leveraging on weighted logical formulas. In this way, we can model the possible synergies among the qualities that are relevant for categorising an object under a concept. (...) We show that our proposal can account for a number of views of concepts such as the prototype theory and the exemplar theory. Moreover, we show how the proposed model can overcome some limitations of cognitive views. (shrink)

(Recipient of the 2020 Everett Mendelsohn Prize.) This article revisits the development of the protoplasm concept as it originally arose from critiques of the cell theory, and examines how the term “protoplasm” transformed from a botanical term of art in the 1840s to the so-called “living substance” and “the physical basis of life” two decades later. I show that there were two major shifts in biological materialism that needed to occur before protoplasm theory could be elevated to have equal status (...) with cell theory in the nineteenth century. First, I argue that biologists had to accept that life could inhere in matter alone, regardless of form. Second, I argue that in the 1840s, ideas of what formless, biological matter was capable of dramatically changed: going from a “coagulation paradigm” that had existed since Theophrastus, to a more robust conception of matter that was itself capable of movement and self-maintenance. In addition to revisiting Schleiden and Schwann’s original writings on cell theory, this article looks especially closely at Hugo von Mohl’s definition of the protoplasm concept in 1846, how it differed from his primordial utricle theory of cell structure two years earlier. This article draws on Lakoff and Johnson’s theory of “ontological metaphors” to show that the cell, primordial utricle, and protoplasm can be understood as material container, object, and substance, and that these overlapping distinctions help explain the chaotic and confusing early history of cell theory.

A characteristic form of philosophical inquiry seeks to answer ‘what is x?’ questions. In this paper, we ask how philosophers do and should adjudicate debates about the correct answer to such questions. We argue that philosophers do and should rely on a distinctive type of pragmatic and meta-representational reasoning – a form of rationalizing self-interpretation – in answering ‘what is x?’ questions. We start by placing our methodological discussion within a broader theoretical framework. We posit a necessary connection between epistemic (...) methodology and metasemantics. In our view, the correct semantic assignment for a representation must be justifiable from the epistemic perspective of the subject herself, given suitable empirical information and cognitive powers. So the upshot of your own ideal, fully informed epistemic methods will determine the correct answers to ‘what is x?’ questions. The bulk of the paper is devoted to articulating and defending our rationalizing self-interpretation account of philosophical methodology. By working through a specific example, we seek to isolate the relevant inputs into deliberation and the methods for adjudicating between competing answers to a ‘what is x?’ question. We suggest that the self-interpretive methods we isolate generalize across the board as a way of identifying the real nature of familiar topics. We also explain how these methods undercut the case for a priori conceptual analysis. (shrink)

What is a concept? Philosophers have given many different answers to this question, reflecting a wide variety of approaches to the study of mind and language. Nonetheless, at the most general level, there are two dominant frameworks in contemporary philosophy. One proposes that concepts are mental representations, while the other proposes that they are abstract objects. This paper looks at the differences between these two approaches, the prospects for combining them, and the issues that are involved in the dispute. We (...) argue that powerful motivations have been offered in support of both frameworks. This suggests the possibility of combining the two. Unlike Frege, we hold that the resulting position is perfectly coherent and well worth considering. Nonetheless, we argue that it should be rejected along with the view that concepts are abstract objects. (shrink)

Given the fundamental role that concepts play in theories of cognition, philosophers and cognitive scientists have a common interest in concepts. Nonetheless, there is a great deal of controversy regarding what kinds of things concepts are, how they are structured, and how they are acquired. This chapter offers a detailed high-level overview and critical evaluation of the main theories of concepts and their motivations. Taking into account the various challenges that each theory faces, the chapter also presents a novel approach (...) to concepts that is organized around two ideas. The first is a pluralistic view of differing types of conceptual structure. The second is a model that treats concepts as atomic representations that are linked to various types of conceptual structures. (shrink)

Philosophers and historians of science have made the claim that successive scientific theories are incommensurable, that is, that many or all of their concepts fail to coincide. This claim has been echoed by cognitive psychologists who have applied it to the successive conceptual schemes of young children, or of children and adults. This paper examines the psychological evidence for the claim and proposes ways of reinterpreting it which do not involve imputing incommensurability. An alternative approach to understanding conceptual change is (...) suggested, according to which novel concepts are introduced against a background of shared concepts, rather than as part of incommensurable conceptual schemes.

Two main theories of concepts have emerged in the recent psychological literature: the Prototype Theory (which considers concepts to be self-contained lists of features) and the Theory Theory (which conceives of them as being embedded within larger theoretical networks). Experiments supporting the first theory usually differ substantially from those supporting the second, which suggests that these the· ories may be operating at different levels of explanation and dealing with different entities. A convergence is proposed between the Theory Theory and the (...) intentional stance in the philosophy of language and mind. From this stance, concepts should not be thought of as concrete physical entities. (shrink)

A review essay on Peacocke's book A Study of Concepts. Raises questions about the role of the concept of finding an inference primitively compelling and questions of detail about the basic framework, its application to the systematicity of thought, the response to potential objections in the chapters on the metaphysics of concepts and naturalism, and the treatment of the concept of belief.
