It has become commonplace in the theory of concepts to distinguish between questions about the structure and questions about the ontology of concepts. Structural questions concern the way concepts are composed of, or otherwise related to, other concepts (or non-conceptual constituents), while ontological questions concern the metaphysical nature of concepts: how concepts exist (if they exist); what kind of entities they are. A tacit assumption in discussions about the structure and ontology of concepts seems to be that structural and ontological questions can be treated more or less independently of each other. Correspondingly, it might be assumed that one can rather arbitrarily combine structural analyses of concepts with any hypothesis about their ontological make-up. In this paper, we would like to question this assumption with regard to a particular recent development in the structural analysis of concepts, the so-called frame theory. As a matter of fact, most frame theorists adopt a subjectivist theory of concepts. Yet, subjectivism attracts philosophical criticisms, which originate mainly in the writings of the later Ludwig Wittgenstein. While Wittgenstein appreciated the cognitive dimension of concepts, he came to reject the subjectivist’s causal analysis of mental explanation and their ensuing reification of concepts as causally operative mental particulars. Instead, Wittgenstein suggested that concepts are socially imparted norms of classification and inference – i. e., abstractions from collective word-usages and other practices associated with categorizing and higher-order thinking, which may serve as instructions for individual agents on how to discriminate and interact with things of different kinds. Applying the Wittgensteinian critique of subjectivism to the frame analysis, the we not only find that the frame approach quite nicely dovetails with what the pragmatist has to say about concepts and categorization, insofar as frames seem particularly well-suited to depict the defeasible and context-dependent default character of our usual criteria for semantical understanding. Indeed, pragmatism, with its emphasis on the holistic, indeterminate and normative nature of our conceptual activities, seems able to explain why concepts are frames. This shows that there exist at least some interconnections between structural and ontological analyses, which must not be ignored, especially in interdisciplinary investigations on concepts. Even if frame theory is not strictly incompatible with a subjectivist ontology, it does license an abductive inference to a pragmatist ontology of concepts, as frames precisely formalize the insights into our actual conceptual practice that led Wittgenstein to develop his pragmatist view.

In this paper, I discuss Michael Moore’s and Jonathan Schaffer’s views on the ontology of omissions in context of their stances on the problem of omissive causation. First, I consider, from a general point of view, the question of the ontology of omissions, and how it relates to the problem of omissive causation. Then I describe Moore’s and Schaffer’s particular views on omissions and how they combine with their stances on the problem of omissive causation. I charge Moore and Schaffer with inconsistencies and insufficiencies within their overall theories, and consider their replies. Finally, I propose my own view on the ontology of omissions and solution to the problem of omissive causation

David Hume’s and later Ludwig Wittgenstein’s views on concepts are generally presented as standing in stark opposition to each other. In a nutshell, Hume’s theory of concepts is taken to be subjectivistic and atomistic, while Wittgenstein is metonymic with a broadly pragmatistic and holistic doctrine that gained much attention during the second half of the 20th century. In this essay, I shall argue, however, that Hume’s theory of concepts is indeed much more akin to the views of Wittgenstein and his epigones than many, including Wittgenstein himself, probably might have suspected. As I try to show, Hume anticipates many themes central to Wittgenstein’s writings on language and meaning, and actually takes initial steps towards both an anti-subjectivistic and anti-atomistic psychology and epistemology.

Few philosophers believe in the existence of so-called negative properties. Indeed, many find it mind-boggling just to imagine such properties. In contrast, I think not only that negative properties are quite imaginable, but also that there are good reasons for believing that some such properties actually exist. In this paper, I want to defend the reality and irreducibility, or genuineness, as I call it, of negative properties. After briefly presenting the idea of a negative property, I collect commonly invoked tests for the realness of things and attend to the question whether negative properties pass any of these. Next, I try to segregate the many different notions of irreducibility, probing whether negative properties can be reckoned to be genuine in any sense of the word. In the final section, I rebut some frequent objections raised against negative properties. _German_ Wenige Philosophen glauben an die Existenz sogenannter negativer Eigenschaften. Die meisten halten solche Eigenschaften sogar für unvorstellbar. Ich dagegen halte negative Eigenschaften nicht nur für denkbar, sondern glaube darüber hinaus, dass solche Eigenschaften tatsächlich existieren. In diesem Aufsatz möchte ich die Wirklichkeit und Irreduzibilität – oder Echtheit – negativer Eigenschaften verteidigen. Nachdem ich kurz die Idee einer negativen Eigenschaft vorstelle, ziehe ich geläufige Kriterien für die Realität von Dingen heran und überprüfe, ob negative Eigenschaften diese erfüllen. Als nächstes unterscheide ich verschiedene Begriffe von Irreduzibilität, um zu überprüfen, ob negative Eigenschaften als echt in irgendeinem Sinn des Wortes betrachtet werden können. Im letzten Abschnitt möchte ich einige häufige Einwände gegen negative Eigenschaften zurückweisen

Absences, i.e., agential omissions and forbearances, but also ‘natural’ negative states and events beyond the sphere of human agency, seem to be part and parcel of the real world. Yet, it is exactly the putative reality of absences that strikes many philosophers as utterly mysterious, if not entirely unintelligible. As a promising approach towards solving the problem of real absences, I wish to explore the idea that absences are latent potentialities. To this end, I shall investigate what potentialities are, what kinds of potentiality exist, and what it means for a potentiality to remain latent. I will also discuss whether the framework of latent potentiality is able to meet the extensional constraints imposed on the theory of absences by our intuitions about the reach of negative acts and events, i.e., whether latent potentialities can account for all real absences.

Moore is one of the many law theorists who doubt that omissions can operate as factors in the causation of events and that in cases in which potential agents remain passive in spite of an obligation to intervene ascriptions of responsibility are justified exclusively by non-causal factors. The paper argues that this is an uneasy and essentially unstable position. It also shows that Moore himself, in Causation and Responsibility, does not consistently follow his exclusion of a causal role of omission in the context of casuistic analysis. Though Moore is to be praised for the clear stance he takes on the issue of negative causality, an analysis of the reasons given for the negation of causality by omission shows that these do not carry enough weight to compensate the sacrifice in theoretical coherence made by the special treatment of negative responsibility in cases in special obligations. It is proposed, instead, that the fact that responsibility for omissions is, as a rule, weaker than that for positive acts is better explained by non-causal factors such as the significant, though incomplete, correlation of the active-passive distinction with a number of normatively relevant factors and the greater social significance of moral and legal rules against active over against passive forms of wrongdoing.

„Negative Kausalität“ bezeichnet ein hochkontroverses metaphysisches Problem. Können negative Entitäten wie Abwesenheiten oder das Nicht-Eintreten bestimmter Ereignisse Ursachen oder Ursachenfaktoren sein? Diese Frage steht im Schnittpunkt einer Reihe disziplinübergreifender Grundfragen: der Frage nach dem Wesen von Kausalität, der Frage nach der Natur von Handlungen und Ereignissen und der Frage nach der Beziehung zwischen Kausalität und normativer - moralischer und rechtlicher - Verantwortlichkeit. Die vorliegende Studie entwickelt im ersten Schritt eine Konzeption von negativer Kausalität ausgehend vom Sonderfall der handlungsförmigen negativen Kausalität, der Kausalität durch Unterlassen. In einem zweiten Schritt erkundet sie anhand des Ariadnefadens der Kausalität von Unterlassungen die terra incognita der Kausalität andersartiger „negativer Ereignisse“ wie Abwesenheiten und Nicht-Ereignissen. In einem dritten Schritt zieht sie Konsequenzen für hartnäckige Probleme wie die Aufteilung der Kausalität beim Zusammentreffen mehrer negativer Ursachen. _English_ The term “negative causality” denotes a highly controversial problem in metaphysics: Can negative entities such as the absence or the non-occurrence of certain events be causes or causal factors? This question is situated at the intersection of a series of fundamental questions that transcend disciplinary boundaries, questions concerning not only the nature of causality, actions, and events, but also the relationship between causality and moral and legal responsibility. This book is intended for philosophers, legal theorists, and theorists of science.

Within a single paragraph in his Treatise of Human Nature, David Hume prompted what has become one of the most central orthodoxies in ethical theory: the thesis that one cannot derive what ought to be from what there is. In the aftermath of Hume’s seminal discussion, the No-Ought-From-Is-thesis has obtained approval among moral theorists to the point that it has been assigned the status of an undisputed ‘law’. As common with commonplaces in philosophy, alas, both the exact content and argument of ‘Hume’s Law’ have proven to be quite elusive. The present anthology aims to clarify and discuss several controversies surrounding the No-Ought-From-Is-thesis.
