Drawing on recent phenomenological discussions of collective intentionality and existential phenomenological accounts of agency, this article proposes a novel interpretation of shared action. First, I argue that we should understand action on the basis of how an environment pre-reflectively solicits agents to behave based on (a) the affordances or goals inflected by their abilities and dispositions and (b) their self-referential commitment to a project that is furthered by these affordances. Second, I show that this definition of action is sufficiently flexible (...) to account for not only individual action (in which both (a) and (b) refer only to an individual) but also several distinct subtypes of shared action. My thesis is that behaviour counts as shared action if and only if it is caused by a solicitation in which either (a) the goals, or (b) the commitments, or both (a) goals and (b) commitments are joint, i.e., depend on several individuals. We thereby get three distinct subtypes of shared actions: (i) jointly coordinated individually committed action, (ii) individually coordinated jointly committed action, and (iii) jointly coordinated jointly committed action.

It is no exaggeration to say that of the early 20th century German philosophers who claimed to establish a new ontology, former neo-Kantian turned realist Nicolai Hartmann is the only one to have actually followed through. "Ontology: Laying the Foundations" deals with "what is insofar as it is," and its four parts tackle traditional ontological assumptions and prejudices and traditional categories such as substance, thing, individual, whole, object, and phenomenon; a novel redefinition of existence and essence in terms of the (...) ontological factors Dasein and Sosein and their interrelations; an analysis of modes of "givenness" and the ontological embeddedness of cognition in affective transcendent acts; and a discussion of the status of ideal being, including mathematical being, phenomenological essences, logical laws, values, and the interconnections between the ideal and real spheres. Hartmann’s work offers rich resources for those interested in overcoming the human-centeredness of much 20th century philosophy.

We discuss the principles for a primitive, object-linguistic notion of consequence proposed by ) that yield a version of Curry’s paradox. We propose and study several strategies to weaken these principles and overcome paradox: all these strategies are based on the intuition that the object-linguistic consequence predicate internalizes whichever meta-linguistic notion of consequence we accept in the first place. To these solutions will correspond different conceptions of consequence. In one possible reading of these principles, they give rise to a notion (...) of logical consequence: we study the corresponding theory of validity by showing that it is conservative over a wide range of base theories: this result is achieved via a well-behaved form of local reduction. The theory of logical consequence is based on a restriction of the introduction rule for the consequence predicate. To unrestrictedly maintain this principle, we develop a conception of object-linguistic consequence, which we call grounded consequence, that displays a restriction of the structural rule of reflexivity. This construction is obtained by generalizing Saul Kripke’s inductive theory of truth. Grounded validity will be shown to satisfy several desirable principles for a naïve, self-applicable notion of consequence. (shrink)

The book is the first English translation of Nicolai Hartmann's seminal book which addresses all philosophical questions of the arts. It will be of value to graduate students in philosophy, scholars concerned with 20th century Continental philosophy, students of aesthetics and art history and criticism, and persons in and out of academic philosophy who wish to develop their aesthetic understanding and responsiveness to art and music.

Some moral philosophers argue that we hold others and ourselves morally responsible for acting on second-personal reasons. This article connects this idea with the emerging literature on the moral responsibility of groups by exploring in which sense, if any, groups can be held accountable for acting on second-personal reasons. On the developed view, groups are second-personally competent if and only if they possess capacities for sympathy, acting on that sympathy, and related self-reactive attitudes. Focusing especially on loosely structured groups without (...) unifying decision-making procedures, the article goes on to argue that the required group-level capacities can be realized through the interdependent exercise of member-level capacities.

We study the relationships between two clusters of axiomatizations of Kripke’s fixed-point models for languages containing a self-applicable truth predicate. The first cluster is represented by what we will call ‘\-like’ theories, originating in recent work by Halbach and Horsten, whose axioms and rules are all valid in fixed-point models; the second by ‘\-like’ theories first introduced by Solomon Feferman, that lose this property but reflect the classicality of the metatheory in which Kripke’s construction is carried out. We show that (...) to any natural system in one cluster—corresponding to natural variations on induction schemata—there is a corresponding system in the other proving the same sentences true, addressing a problem left open by Halbach and Horsten and accomplishing a suitably modified version of the project sketched by Reinhardt aiming at an instrumental reading of classical theories of self-applicable truth.

Hartmann sah die Aufgabe der Philosophie nicht in der Überwindung, sondern in der kritischen Reformulierung der klassischen ontologischen Fragestellungen. In dem knappen, ausgereiften Traktat von 1949 umreißt er in dichter Zusammenschau noch einmal die Kerngedanken seines Versuchs einer neuen Grundlegung der Ontologie.

Truth-theoretic deflationism holds that truth is simple, and yet that it can fulfil many useful logico-linguistic roles. Deflationism focuses on axioms for truth: there is no reduction of the notion of truth to more fundamental ones such as sets or higher-order quantifiers. In this paper I argue that the fundamental properties of reasonable, primitive truth predicates are at odds with the core tenets of classical truth-theoretic deflationism that I call fix, express, and quantify. Truth may be regarded as a broadly (...) logical, sui generis notion. However, this has little to do with the original aims of the deflationary theory of truth. (shrink)

As a response to the semantic and logical paradoxes, theorists often reject some principles of classical logic. However, classical logic is entangled with mathematics, and giving up mathematics is too high a price to pay, even for nonclassical theorists. The so-called recapture theorems come to the rescue. When reasoning with concepts such as truth/class membership/property instantiation, (These are examples of concepts that are taken to satisfy naive rules such as the naive truth schema and naive comprehension, and that therefore are (...) compatible with a solution to paradox cast in the logics considered below. Other notions of similar kind can be added to the list.) if one is interested in consequences of the theory that only contain mathematical vocabulary, nothing is lost by reasoning in the nonclassical framework. This article shows that this claim is highly misleading, if not simply false. Under natural assumptions, some well-established approaches to recapture are incorrect. (shrink)

Reissue from the classic Muirhead Library of Philosophy series (originally published between 1890s - 1970s).

Substructural logics and their application to logical and semantic paradoxes have been extensively studied. In the paper, we study theories of naïve consequence and truth based on a non-reflexive logic. We start by investigating the semantics and the proof-theory of a system based on schematic rules for object-linguistic consequence. We then develop a fully compositional theory of truth and consequence in our non-reflexive framework.

According to the implicit commitment thesis, once accepting a mathematical formal system S, one is implicitly committed to additional resources not immediately available in S. Traditionally, this thesis has been understood as entailing that, in accepting S, we are bound to accept reflection principles for S and therefore claims in the language of S that are not derivable in S itself. It has recently become clear, however, that such reading of the implicit commitment thesis cannot be compatible with well-established positions (...) in the foundations of mathematics which consider a specific theory S as self-justifying and doubt the legitimacy of any principle that is not derivable in S: examples are Tait’s finitism and the role played in it by Primitive Recursive Arithmetic, Isaacson’s thesis and Peano Arithmetic, Nelson’s ultrafinitism and sub-exponential arithmetical systems. This casts doubts on the very adequacy of the implicit commitment thesis for arithmetical theories. In the paper we show that such foundational standpoints are nonetheless compatible with the implicit commitment thesis. We also show that they can even be compatible with genuine soundness extensions of S with suitable form of reflection. The analysis we propose is as follows: when accepting a system S, we are bound to accept a fixed set of principles extending S and expressing minimal soundness requirements for S, such as the fact that the non-logical axioms of S are true. We call this invariant component the semantic core of implicit commitment. But there is also a variable component of implicit commitment that crucially depends on the justification given for our acceptance of S in which, for instance, may or may not appear reflection principles for S. We claim that the proposed framework regulates in a natural and uniform way our acceptance of different arithmetical theories. (shrink)

This is a translation of Nicolai Hartmann’s article “Der Megarische und der Aristotelische Möglichkeitsbegriff: ein Beitrag zur Geschichte des ontologischen Modalitätsproblems,” first published in 1937. In this article, Hartmann defends an interpretation of the Megarian conception of possibility, which found its clearest form in Diodorus Cronus’ expression of it and according to which “only what is actual is possible” or “something is possible only if it is actual.” Hartmann defends this interpretation against the then dominant Aristotelian conception of possibility, based (...) on the opposition between dynamis and energeia, and according to which there is always an open multiplicity of simultaneous “possibilities,” the outcome of which remains undetermined. Since, according to Hartmann, reality suffers no indetermination, the Megarian conception of possibility is an account of real possibility, whereas the Aristotelian one is merely an account of epistemic possibility.

In the paper we investigate typed axiomatizations of the truth predicate in which the axioms of truth come with a built-in, minimal and self-sufficient machinery to talk about syntactic aspects of an arbitrary base theory. Expanding previous works of the author and building on recent works of Albert Visser and Richard Heck, we give a precise characterization of these systems by investigating the strict relationships occurring between them, arithmetized model constructions in weak arithmetical systems and suitable set existence axioms. The (...) framework considered will give rise to some methodological remarks on the construction of truth theories and provide us with a privileged point of view to analyze the notion of truth arising from compositional principles in a typed setting.

The existence of a close connection between results on axiomatic truth and the analysis of truth-theoretic deflationism is nowadays widely recognized. The first attempt to make such link precise can be traced back to the so-called conservativeness argument due to Leon Horsten, Stewart Shapiro and Jeffrey Ketland: by employing standard Gödelian phenomena, they concluded that deflationism is untenable as any adequate theory of truth leads to consequences that were not achievable by the base theory alone. In the paper I highlight, (...) as Shapiro and Ketland, the irreducible nature of truth axioms with respect to their base theories. But, I argue, this does not immediately delineate a notion of truth playing a substantial role in philosophical or scientific explanations. I first offer a refinement of Hartry Field’s reaction to the conservativeness argument by distinguishing between metatheoretic and object-theoretic consequences of the theory of truth and address some possible rejoinders. In the resulting picture, truth is an irreducible tool for metatheoretic ascent. How robust is this characterizaton? I test it by considering: a recent example, due to Leon Horsten, of the alleged explanatory role played by the truth predicate in the derivation of Fitch’s paradox; an essential weakening of theories of truth analyzed in the first part of the paper.

We determine the modal logic of fixed-point models of truth and their axiomatizations by Solomon Feferman via Solovay-style completeness results. Given a fixed-point model $\mathcal {M}$, or an axiomatization S thereof, we find a modal logic M such that a modal sentence $\varphi $ is a theorem of M if and only if the sentence $\varphi ^*$ obtained by translating the modal operator with the truth predicate is true in $\mathcal {M}$ or a theorem of S under all such translations. (...) To this end, we introduce a novel version of possible worlds semantics featuring both classical and nonclassical worlds and establish the completeness of a family of noncongruent modal logics whose internal logic is nonclassical with respect to this semantics.

Adam Ferguson, lecturer of moral philosophy at the University of Edinburgh , was one of the leading figures of the Scottish Enlightenment. His published works, however, have sometimes been dismissed as derivative and viewed as less important than some of his contemporaries, because of his reliance on ancient Stoic philosophy. An analysis of Ferguson's lecture notes, conversely, demonstrates Stoicism's pedagogical function. Rather than adopting Stoic principles, Ferguson used their terminology to teach philosophical concepts. Ferguson's nuanced discussion of ancient philosophy in (...) his lectures demonstrated his critiques of the ancient schools and his purpose for employing their language throughout his texts.

One way to study and understand the notion of truth is to examine principles that we are willing to associate with truth, often because they conform to a pre-theoretical or to a semi-formal characterization of this concept. In comparing different collections of such principles, one requires formally precise notions of inter-theoretic reduction that are also adequate to compare these conceptual aspects. In this work I study possible ways to make precise the relation of conceptual equivalence between notions of truth associated (...) with collections of principles of truth. In doing so, I will consider refinements and strengthenings of the notion of relative truth-definability proposed by Fujimoto (2010): in particular I employ suitable variants of notions of equivalence of theories considered in Visser (2006) and Friedman & Visser (2014) to show that there are better candidates than mutual truth-definability for the role of sufficient condition for conceptual equivalence between the semantic notions associated with the theories. In the concluding part of the paper, I extend the techniques introduced in the first and show that there is a precise sense in which ramified truth (either disquotational or compositional) does not correspond to iterations of comprehension.

Heidegger is often criticised for having next to nothing to say about human sociality. Yet, his work provides neglected resources for understanding the nature of social life. Drawing on his celebrated philosophy of mind and philosophy of action, the book systematically reconstructs Heidegger’s social ontology. It argues that Heidegger’s famous claim that human mindedness and agency is constitutively being-in-the-world implies that we can only understand others, do things with others, and form lasting groups with others if we pre-reflectively correlate their (...) behaviour with our own projects and the world that lies between us. Drawing on both his published texts, lecture courses, and notebooks, the book puts Heidegger into dialogue with contemporary debates on social cognition, collective intentionality, and social normativity, while also reassessing the significance of his account of authenticity and criticising his affiliation with Nazism. Written in a clear and engaging style, this book is an essential contribution to contemporary phenomenology and social ontology. (shrink)

This is a translation of an early essay by the German philosopher Nicolai Hartmann (1882–1950). In this 1923 essay Hartmann presents many of the fundamental ideas of his new critical ontology. He summarizes some of the main points of his critique of neo-Kantian epistemology, and provides the point of departure for his new approach in an extensive criticism of the errors of the classical ontological tradition. Some of these errors concern the definition of an ontological category or principle, and others (...) concern the relations among categories themselves. The outline for the new ontology is sketched through the correctives Hartmann appends to the treatment of each error, prefiguring his mature ontological system. (shrink)

This article traces the development of how the early Heidegger tried to integrate the structures of social life into phenomenological ontology. Firstly, I argue that Heidegger's analysis of the three elements of the lifeworld—the with-world (Mitwelt), the environing world (Umwelt), and the self-world (Selbstwelt)—is ambiguous, because it shifts between defining sociality as a domain of entities and a mode of appearance. This is untenable because the social as a mode of appearance constantly overflows the definition as a domain by implicating (...) social structures in phenomenological explications of entities that, formally, belong to other domains. Secondly, I argue that Heidegger realized this and subsequently changed his terminology from Mitwelt to Mitsein in order to avoid confusing the mode of appearance with the innerworldly entities. The systematic consequence of this line of argument is that the object of social ontology must be the world as such rather than a particular domain. Lastly, I respond to the common worry that this position is unable to explain the significance of interpersonal encounters by arguing that the world not only makes the appearance of others possible but also that the world is itself at stake in these encounters.
