This chapter covers the traditional role of responsibility, and the possible connections between response and responsibility. These connections are explored through the advance of trust and the surplus of the extraordinary in relation to the Third Party. The idea of responsibility comes from the sphere of juridical law, and has a theological touch. The classical conception presented suffers from a permanent erosion that is reinforced by systemic constraints. Trust is a natural element of every community that is together applied by (...) common aims in life. The phenomenon of trust refers to the bond, the nexus, which holds together the members of a community, creating the requisite solidarity. The term ‘trust’ or ‘confidence’ should not primarily read as a substantive, but as a verb or as the derivative of a verb. Furthermore, it is noted that the responsive ethics proposed could function as a permanent corrective. (shrink)

We specify two problems in syllogistic: the lack of functoriality of predicates (although a thief is a person, a good thief may not be a good person) and the change of grammatical role of the middle term, from subject to predicate, in some syllogisms. The standard semantics, the class interpretation, by-passes these difficulties but, we argue, in a manner that is at odds with logical intuition. We propose a semantics that is category theoretic to handle these difficulties. With this semantics (...) we specify when syllogisms are valid and we set limits to the class interpretation. To perform this task we show how to construct the categorical notion of an entity in a system of kinds. We devote two brief sections to an argument that our approach is very much in the spirit of Aristotle. (shrink)

Good’s theorem is the apparent platitude that it is always rational to ‘look before you leap’: to gather information before making a decision when doing so is free. We argue that Good’s theorem is not platitudinous and may be false. And we argue that the correct advice is rather to ‘make your act depend on the answer to a question’. Looking before you leap is rational when, but only when, it is a way to do this.

Epistemologists have recently noted a tension between (i) denying access internalism, and (ii) maintaining that rational agents cannot be epistemically akratic, believing claims akin to ‘p, but I shouldn’t believe p’. I bring out the tension, and develop a new way to resolve it. The basic strategy is to say that access internalism is false, but that counterexamples to it are ‘elusive’ in a way that prevents rational agents from suspecting that they themselves are counterexamples to the internalist principles. I (...) argue that this allows us to do justice to the motivations behind both (i) and (ii). And I explain in some detail what a view of evidence that implements this strategy, and makes it independently plausible, might look like. (shrink)

Without directly addressing the Demarcation Problem for logic—the problem of distinguishing logical vocabulary from others—we focus on distinctive aspects of logical vocabulary in pursuit of a second goal in the philosophy of logic, namely, proposing criteria for the justification of logical rules. Our preferred approach has three components. Two of these are effectively Belnap’s, but with a twist. We agree with Belnap’s response to Prior’s challenge to inferentialist characterisations of the meanings of logical constants. Belnap argued that for a logical (...) constant to exist, its rules must be conservative over a previously given consequence relation and guarantee the uniqueness of the constant. The twist is that we require logical vocabulary to be provably conservative, not over a previously given formal consequence relation, but over a previously given meaningful vocabulary of a language. Uniqueness is also a feature defined in terms of provability: if two syntactically distinguished expressions are governed by the same rules, then formulas with them as main operators are interderivable. Belnap’s criteria are not only those for the existence of a logical constant, but more: they are what distinguishes logical vocabulary from all other expressions. It is the defining mark of a logical constant that it is provably conservative over the fragment of the language which excludes it and that its rules guarantee its uniqueness. The third component is the topic neutrality of logic. The provable conservativeness of logic over a previously given vocabulary of a language is motivated, in part, by appeal to molecularism in the theory of meaning. Molecularity is a feature endorsed by the theory of meaning as a whole, so it does not distinguish logical constants from other expressions. The same is true for conservativeness. We argue that molecularity, and hence conservativeness, are implicit presuppositions of speakers’ use of language: the addition of new vocabulary to a language is presupposed to be conservative. But this presupposition is one that we should be able reflectively to endorse (such as when attempting a rational reconstruction of the use of the vocabulary). Thus, where conservativeness is found to fail, this defect should be remedied and the use of the vocabulary corrected (as in classical negation) or excised altogether (as in pejoratives). We go on to characterise a notion of topic neutrality, which we argue applies to logical vocabulary. We then note that reflective endorsement of the conservativeness of a topic neutral vocabulary requires a proof that the vocabulary is conservative relative to any base vocabulary. Thus we require that logical vocabulary be demonstrably conservative. Allying this requirement, distinctive of logic, to a general consideration about the commitments of assertion yields a mode of justification for logical constants akin to some conceptions of Harmony, i.e., to the idea that the consequences of assertion of a logical complex need to be warranted by the grounds and ought to be the strongest consequences warranted by the grounds. Intuitionistic logic acquires a somewhat familiar justification but emanating from a new motivation. (shrink)

This comment deals with some basic elements Searle uses in order to construct social reality, i.e. togetherness, we-intentionality and the distinction between institutional and brute facts. The commentator argues that Searle’s theory tends to a partial biologism because lacking a sufficient concept of embodiment. Consequently ‘pre-institutional facts’ such as eating, copulating, working or torturing are systematically underdetermined. On the deontic level the theory relies on natural processes of conventional power. So the distinction between factual acceptance and acceptability is blurred by (...) a sort of conformism, and one neglects the status of dissidents and victims whose belonging to the predominant ‘we’ remains highly dubious.

Bernhard Nickel presents a theory of generic sentences and the kind-directed modes of thought they express. The theory closely integrates compositional semantics with metaphysics to solve the problem that generics pose: what do generics mean? Generic sentences are extremely simple, yet if there are patterns to be discerned in terms of which are true and which are false, these patterns are subtle and complex. Ravens are black, and lions have manes: statistical measures cannot do justice to the facts, but (...) what else is there that has a hope of giving us insight into what we are capturing across so many domains? Nickel argues that generics are the top of a fundamentally explanatory iceberg, and that this explanatory framework is deeply intertwined with the semantics of the language we use to express them. In providing an integrated semantic and metaphysical theory of generics, he aims to solve old puzzles and draw attention to new phenomena. (shrink)

In der vorliegenden Schrift soll Martin Buber als dem scharfen Diagnostiker unserer Zeit und dem Künder ewiger Wahrheiten die ganze Aufmerksamkeit gelten. Kein Denken lässt sich so wenig in billigen Schlagwörtern einfangen, wie das Martin Bubers. Die erste Aufgabe wird sein, die Situation in der wir leben, und die Buber meint, etwas näher zu bestimmen. Dies wird uns in die Lage setzen, jene Fragen zu vernehmen, die die Situation zu uns allen spricht. Sodann werden wir uns der besonderen Gestalt der (...) Buberschen Antwort zuwenden. Erst dann erscheint die Frage nach Herkunft und Inhalt der Antwort sinnvoll. In einem letzten Teil sollen dann gleichsam drei Bewährungsproben von Bubers Denken erörtert werden. (shrink)

The last decade has seen an explosion of research on the gut microbiota—the trillions of microorganisms that colonize the human gut. It is now clear that interindividual diversity in microbiota composition plays an important role in determining susceptibility to a wide variety of diseases. However, identifying the precise changes in microbiota composition that play causal roles has remained a largely unrealized goal. Here, we propose that functional classifications of microbes based on their interactions with and effects on the host—particularly the (...) host immune system—will illuminate the role of the microbiota in shaping human physiology. We outline the benefits of “functional” classification compared to phylogenetic classifications, and review current efforts at functional classification of the microbiota. Finally, we outline a theoretical framework for classifying host-microbiota interactions. Future advances enabling broader functional classifications of the microbiota promise to revolutionize our understanding of the role of gut microbes in health and disease. Functional classifications of the human microbiota reveal previously hidden patterns and will be key to cracking the microbiota composition code. This figure shows a theoretical comparison between phylogenetic classification and functional classification of a host-associated microbial community. (shrink)

This book develops an empirically informed normative theory of need-based justice, summarizing core findings of the DFG research group FOR2104 “Need-based Justice and Distributive Procedures”. In eleven chapters scholars from the fields of economics, political science, philosophy, psychology, and sociology cover the identification and rationale of needs, the recognition and legitimacy of needs, the dynamics and stability of procedures of distributions according to needs, and the consequences and sustainability of need-based distributions. These four areas are studied from the perspective of (...) two mechanisms of need objectification, the social objectification by the discursive generation of mutual understanding (transparency) and the factual objectification by the transfer of decisions to uninvolved experts (expertise). The volume addresses academics in the fields of justice research, ethics, political theory, social choice and welfare, framing, individual and group decision making, inequality and redistribution, as well as advanced students in the contributing disciplines.

Recent neuroeconomic studies challenge the conventional economic logic of behavior. After an introduction to some starting points of brain research in ‘classical’ economics we discuss the final and contingent causes of rational and irrational behavior in neuroeconomics and standard economics and present the concept of expanded rationality models (ERM) which imports neuroeconomic elements like emotions, beliefs and neuroscientific constraints and exports improved testable predictions. The typical structure of neuroeconomic proof of economic models and the imprecise neuroscientific measurement let us suggest (...) a feed-back structure of economic research. We apply Hirshleifer’s conception of macro-/micro-technology and contrast it to the neuroeconomic black box critique on economic theory. Furthermore, instead of direct adjustment of preference structures we propose the auxiliary creation of neuroeconomic constraints like action-dependent or outcome-dependent neuroeconomic belief constraints (NBC) and emotion compatibility constraints (ECC). This prepares the ground for our examination of neuroeconomics and ERM as two different paths towards an analytical unification of behavioral sciences. (shrink)
