Response to critical comments by Edward Slowik on my article 'Leibniz on Motion and the Equivalence of Hypotheses' in The Leibniz Review 18 (2008).

This essay examines some of the ways in which the assumption of the essential finitude of the human mind, in contrast to the infinitude of God’s mind, bears on Leibniz’s and Kant’s accounts of our representational capacities. This examination reveals several underappreciated similarities between their views, but also some notable differences that help us pinpoint where and in what ways Kant departs from his celebrated predecessor. The fruits of this examination are a better understanding of Kant’s conception of the discursivity (...) of our understanding, his account of the difference between concepts and intuitions, and the particular flavor of his idealism. -/- .

A popular story about Kant's relation to Leibniz presents Kant as a Leibniz-Wolffian by education who, inspired by his encounter with the teachings of Newton and Hume, took on the project of reconciling Leibniz-Wolffian metaphysics with Newtonian science and of responding to epistemological skepticism, a project that led him further and further away from his Leibniz-Wolffian roots and culminated in the total rejection of the Leibniz-Wolffian philosophy in the Critique of Pure Reason. In this essay, four shortcomings of the popular (...) story are identified and several suggestions are made about how to amend and expand the story in order to overcome these shortcomings. Furthermore, some of the most important Leibnizian doctrines that influenced Kant are collected and their role in Kant's philosophy is discussed. (shrink)

Wittgenstein famously criticizes the philosophical practice of analyzing the meaning of words outside their ordinary use in everyday language, whereby often self-made pseudo-problems arise. In order to shed further light on Wittgenstein’s critique, this article makes use of the Remarks on the Philosophy of Psychology. First, starting from the remark in Vol. I, §52, his criticism of the philosophical method of selection and generalization is explained in detail. Next, I give a brief outline of Wittgenstein’s own way of philosophizing by (...) reference to a selection of comments concerning the use of psychological words in everyday language, which will also further elucidate his critique. Finally, I enter into the question which significance everyday language according to Wittgenstein has for philosophy. (shrink)

According to an attractive account of belief, our beliefs have centered content. According to an attractive account of communication, we utter sentences to express our beliefs and share them with each other. However, the two accounts are in conflict. In this paper I explore the consequences of holding on to the claim that beliefs have centered content. If we do in fact express the centered content of our beliefs, the content of the belief the hearer acquires cannot in general be (...) identical to the content the speaker expresses. I sketch an alternative account of communication, the Recentering model, that accepts this consequence and explains how expressed and acquired content are related. (shrink)

Griffiths et al. (2015) have proposed a quantitative measure of causal specificity and used it to assess various attempts to single out genetic causes as being causally more specific than other cellular mechanisms, for example, alternative splicing. Focusing in particular on developmental processes, they have identified a number of important challenges for this project. In this discussion note, I would like to show how these challenges can be met.

I present a reconstruction of F.H.C. Crick's two 1957 hypotheses "Sequence Hypothesis" and "Central Dogma" in terms of a contemporary philosophical theory of causation. Analyzing in particular the experimental evidence that Crick cited, I argue that these hypotheses can be understood as claims about the actual difference-making cause in protein synthesis. As these hypotheses are only true if restricted to certain nucleic acids in certain organisms, I then examine the concept of causal specificity and its potential to counter claims about (...) causal parity of DNA and other cellular components. I first show that causal specificity is a special kind of invariance under interventions, namely invariance of generalizations that range over finite sets of discrete variables. Then, I show that this notion allows the articulation of a middle ground in the debate over causal parity. (shrink)

The recent literature on causality has seen the introduction of several distinctions within causality, which are thought to be important for understanding the widespread scientific practice of focusing causal explanations on a subset of the factors that are causally relevant for a phenomenon. Concepts used to draw such distinctions include, among others, stability, specificity, proportionality, or actual-difference making. In this contribution, I propose a new distinction that picks out an explanatorily salient class of causes in biological systems. Some select causes (...) in complex biological systems, I argue, have the property of enabling coherent causal control of these systems. Examples of such control variables include hormones and other signaling molecules, e.g., TOR (target of rapamycin), morphogens or the products of homeotic selector genes in embryonic pattern formation. I propose an analysis of this notion based on concepts borrowed from causal graph theory. (shrink)

I examine different arguments that could be used to establish indeterminism of neurological processes. Even though scenarios where single events at the molecular level make the difference in the outcome of such processes are realistic, this falls short of establishing indeterminism, because it is not clear that these molecular events are subject to quantum mechanical uncertainty. Furthermore, attempts to argue for indeterminism autonomously (i.e., independently of quantum mechanics) fail, because both deterministic and indeterministic models can account for the empirically observed (...) behavior of ion channels. (shrink)

Causal selection is the task of picking out, from a field of known causally relevant factors, some factors as elements of an explanation. The Causal Parity Thesis in the philosophy of biology challenges the usual ways of making such selections among different causes operating in a developing organism. The main target of this thesis is usually gene centrism, the doctrine that genes play some special role in ontogeny, which is often described in terms of information-bearing or programming. This paper is (...) concerned with the attempt of confronting the challenge coming from the Causal Parity Thesis by offering principles of causal selection that are spelled out in terms of an explicit philosophical account of causation, namely an interventionist account. I show that two such accounts that have been developed, although they contain important insights about causation in biology, nonetheless fail to provide an adequate reply to the Causal Parity challenge: Ken Waters's account of actual-difference making and Jim Woodward's account of causal specificity. A combination of the two also doesn't do the trick, nor does Laura Franklin-Hall's account of explanation (in this volume). We need additional conceptual resources. I argue that the resources we need consist in a special class of counterfactual conditionals, namely counterfactuals the antecedents of which describe biologically normal interventions. (shrink)

Hat das menschliche Wesen einen klaren Kern, welchen ihn erst zum Menschen macht? Wie wäre dieser zu definieren? Der Mensch verfügt über viele Fähigkeiten, die ihn zu einem vernünftig agierenden Tier machen. Aber ist das der wesentliche Unterschied zu den anderen Tieren? Das vorliegende Dossier geht der Frage nach, was der Mensch ist und was ihn auszeichnet.

John Searle has argued that functions owe their existence to the value that we put into life and survival. In this paper, I will provide a critique of Searle’s argument concerning the ontology of functions. I rely on a standard analysis of functional predicates as relating not only a biological entity, an activity that constitutes the function of this entity and a type of system but also a goal state. A functional attribution without specification of such a goal state has (...) no truth-value. But if completed with a goal state, functional attributions understood as four-place relations attain a truth-value. The truth conditions of all attributions of function involve a dependence claim of the goal state on the function bearer’s activity. The nature of this dependence may differ; I consider five different possibilities: causality, mechanistic constitution, mereology, supervenience and metaphysical grounding. If these dependency relations are objective, Searle’s central ontological thesis fails. What he ought to have said is that our valuing survival or other goal states may be the reason why biology seeks functional knowledge, but this has nothing to do with ontology. I will show further that Searle also raised an interesting challenge concerning the relationship of functional and causal truths, but it does not threaten the objectivity of functions either. At best, it could show that functional vocabulary is eliminable. However, I will show that functional vocabulary is not so eliminable. (shrink)

Dieses Heft beinhaltet philosophische Perspektiven der Debatten der personalen Identität und der Liebe. Neben der Darstellung der Kerninhalte der beiden Debatten wird die Frage „Wen liebe ich?“ philosophisch problematisiert. Dabei soll aufgezeigt werden, was unter einer philosophischen Herangehensweise zu verstehen ist und wie sich dies konkret im Fall der angeführten Frage niederschlägt.

I examine to what extent accounts of mechanisms based on formal interventionist theories of causality can adequately represent biological mechanisms with complex dynamics. Using a differential equation model for a circadian clock mechanism as an example, I first show that there exists an iterative solution that can be interpreted as a structural causal model. Thus, in principle, it is possible to integrate causal difference-making information with dynamical information. However, the differential equation model itself lacks the right modularity properties for a (...) full integration. A formal mechanistic model will therefore have to leave out either noncausal or causal explanatory relations. (shrink)

Um was geht es beim Bedingungslosen Grundeinkommen? Und weshalb ist es auch ein Thema der Philosophie? Sollte die Gesellschaft grundsätzlich hinterfragen, was unter dem Begriff „Arbeit“ zu verstehen ist? Würde das Grundeinkommen Gerechtigkeit ermöglichen oder verunmöglichen?

It is a widely held view in philosophy that propositions perform a plethora of different theoretical roles. Amongst other things, they are believed to be the semantic values of sentences in contexts, the objects of attitudes, the contents of illocutionary acts, and the referents of that-clauses. This assumption is often combined with the claim that propositions have their truth-values eternally. In this paper I aim to show that these two assumptions are incompatible: propositions cannot both fulfill the mentioned roles and (...) be eternally true or false. Following Kaplan and Lewis’s Operator Argument, I argue that compositional semantic values of sentences in contexts do not correspond to eternal propositions. Thus, either we regard the non-eternal entities that in fact realize the semantic role of propositions as also fulfilling the remaining propositional roles, or we abandon the assumption that there is a unique realizer of all the roles. The Operator Argument has recently come under attack, mainly for its tense-logical assumptions. However, rejecting these assumptions is not a sufficient defense of the compatibility of the two claims, since the extensional alternative to the tense-logical framework does not allow us to universally retain eternal propositions as compositional semantic values of sentences either.

Muss ein Mensch Selbstachtung haben, um Empfänger der Menschenwürde zu sein? Spielt Menschenwürde auch in der Wirtschaft und im Rechtssystem eine Rolle? Und wie lässt sich „Menschenwürde“ überhaupt definieren? Im Dossier findet man die philosophischen Hintergründe zum Thema „Menschenwürde“.

Die Aufgabe der Philosophie besteht nicht darin, den moralischen Zeigefinger zu erheben und vorzugeben, was man tun soll und was nicht. Vielmehr zeigt die Philosophie unterschiedliche Argumente auf, weshalb die eine oder andere Haltung vertretbar oder aus gewissen Gründen gegebenenfalls vertretbarer ist als eine andere. Insofern eine Gesellschaft an Klugheit interessiert ist und sich einer zukünftigen Entwicklung verantwortungsvoll stellt, kann die Philosophie eine wertvolle Aufgabe übernehmen: Die Methode, analytisch das Für und Wider abzuwiegen, bedeutet nicht zuletzt viel Arbeit und Aufmerksamkeit (...) für das Detail. Wie beispielsweise das Kapitel zur Grünen Gentechnik (Seite 6) zeigt, sind die Diskussionen um die zu fällenden moralischen Urteile nicht an ein externes Gremium zu delegieren. Im Gegenteil: Die Diskussion sollte innerhalb der Gesellschaft stattfinden, einerseits um den unterschiedlichen Haltungen Platz zu geben, andererseits aber, weil nur auf diese Weise ein echter Konsens zu Stande kommen kann. Die Rolle der Philosophie zeigt sich ähnlich auch, wenn es um die für die pluralistische Gesellschaft zentrale Toleranz geht. Die wertenden Einstellungen der Bürgerinnen und Bürger verdienen es, ernst genommen zu werden und offen diskutiert zu werden. Nur durch eine tiefgreifende Auseinandersetzung lässt sich verhindern, dass populistische Wortführer mit eigennützigen, aber aufmerksamkeitsstarken Argumenten von den Themen ablenken, die ernsthaft angegangen werden möchten: Die Vision einer friedlichen und freiheitlichen Gesellschaft, das demokratische Ideal, wird nicht mit dem Verweis auf die „Krise“ aufgegeben. Verantwortung interessiert die Bürgerinnen und Bürger schliesslich eben doch mehr, als Donald Trumps neuste Lüge. Das philosophische Themendossier zeigt, dass die akademische Philosophie viel leis-tet, um eine oberflächliche Auseinandersetzung mit gesellschaftlich und zukunftsrelevanten Themen zu verhindern. Auch wenn das auf den ersten Blick nach viel Anstrengung klingt, so zeigt der zweite Blick, dass darin viel Wohlwollen zugunsten der Gesellschaft steckt. Es lohnt sich, den Mut aufzubringen, sich intensiv mit den eigenen Werturteilen auseinanderzusetzen und das Auge vom eigenen Wohl auch auf das Wohle aller schweifen zu lassen. Philosophie kann „ansteckend“ sein und viel Freude hervorrufen: Gerade dann, wenn man neue Ideen mit dazu gewinnt oder andere Argumente für bereits gefasste Entscheidungen kennenlernt. Die Philosophie entwickelt sich fortlaufend weiter und bleibt somit mehr denn je: stets aktuell. (shrink)

It is easy to imagine being someone else from the first-person point of view. Such imaginings give rise to a puzzle. In this paper I explain what the puzzle is and then consider several existing attempts of solving the puzzle. I argue that these attempts are unsuccessful. I propose a Lewisian account of first-person imagination and make the case that this account has the potential to solve the puzzle.

„Im Grunde gibt es nur die Liebe“, sagte Picasso einst. Kaum ein Mensch durchläuft sein Leben, ohne früher oder später von jenen Gefühlen gebeutelt zu werden, welche als Liebe bezeichnet werden. Aber was ist Liebe überhaupt? Gibt es klare Kriterien, die Liebe notwendigerweise aufweist? Welchen Einfluss haben die kulturellen Vorbedingungen auf unsere Vorstellungen von Liebe?

Several authors have used the notion of causal specificity in order to defend non-parity about genetic causes (Waters 2007, Woodward 2010, Weber 2017, forthcoming). Non-parity in this context is the idea that DNA and some other biomolecules that are often described as information-bearers by biologists play a unique role in life processes, an idea that has been challenged by Developmental Systems Theory (e.g., Oyama 2000). Indeed, it has proven to be quite difficult to state clearly what the alleged special (...) role of genetic causes consists in. In this paper, I show that the set of biomolecules that are normally considered to be information-bearers (DNA, mRNA) can be shown to be the most specific causes of protein primary structure, provided that causal specificity is measured over a relevant space of biological possibilities, disregarding physical as well as logically possible states of the causal variables.

This paper examines causal theories of reference with respect to how plausible an account they give of non-physical natural kind terms such as ‘gene’ as well as of the truth of the associated theoretical claims. I first show that reference fixism for ‘gene’ fails. By this, I mean the claim that the reference of ‘gene’ was stable over longer historical periods, for example, since the classical period of transmission genetics. Second, I show that the theory of partial reference does not (...) do justice to some widely held realist intuitions about classical genetics. This result is at loggerheads with the explicit goals usually associated with partial theories of reference, which is to defend a realist semantics for scientific terms. Thirdly, I show that, contrary to received wisdom and perhaps contrary to physics and chemistry, neither reference fixism nor partial reference are necessary in order to hold on to scientific realism about biology. I pinpoint the reasons for this in the nature of biological kinds, which do not even remotely resemble natural kinds (i.e., Lockean real essences) as traditionally conceived. (shrink)

Experimental modeling in biology involves the use of living organisms (not necessarily so-called "model organisms") in order to model or simulate biological processes. I argue here that experimental modeling is a bona fide form of scientific modeling that plays an epistemic role that is distinct from that of ordinary biological experiments. What distinguishes them from ordinary experiments is that they use what I call "in vivo representations" where one kind of causal process is used to stand in for a physically (...) different kind of process. I discuss the advantages of this approach in the context of evolutionary biology. (shrink)

„Gemeinschaft“ steht in der Philosophie nicht nur im Zusammenhang mit ethischen Überlegungen, sondern auch mit Fragen nach der Natur von sozialen Handlungen und dem charakteristischen Wesen von Kollektiven. Gibt es Bedingungen, die erfüllt sein müssen, damit man von einer Gemeinschaft – in Abgrenzung zu „Gesellschaft“ – sprechen kann?

In this paper, I investigate why anorexia nervosa emerged in non-Western nations after Western globalization efforts. Using Simone de Beauvoir’s theory of gender from The Second Sex alongside Michel Foucault’s conceptualization of the “docile body,” I argue that the emergence of anorexia nervosa in non-Western nations reflects the Western sovereign’s subordination of women. While patriarchal oppression is not exclusive to the West, I contend that the political ideology behind Western industrialization has allowed new avenues for patriarchal oppression to permeate. To (...) conclude, I demand that mainstream discourse on anorexia nervosa consider the political conditions which are catalytic to its occurrence. (shrink)

Linguistic structures have recently started to attract attention from economists as determinants of economic phenomena. This paper provides the first comprehensive review of this nascent literature and its achievements so far. First, we explore the complex connections between language, culture, thought and behaviour. Then, we summarize the empirical evidence on the relationship between linguistic structures and economic and social outcomes. We follow up with a discussion of data, empirical design and identification. The paper concludes by discussing implications for future research (...) and policy. (shrink)

Dieses Themendossier zeigt auf, mit welchen Themen sich die Philosophie befasst und wem die Philosophie was nützt. Wo heutzutage Philosophinnen und Philosophen wirken, wird ebenso betrachtet, wie die Frage, weshalb es sich überhaupt lohnt zu philosophieren.

Darwin famously held that his use of the term "chance" in evolutionary theory merely "serves to acknowledge plainly our ignorance of the causes of each particular variation". Is this a tenable view today? Or should we revise our thinking about chance in evolution in light of the more advanced, quantitative models of Neo-Darwinian theory, which make substantial use of statistical reasoning and the concept of probability? Is determinism still a viable metaphysical doctrine about biological reality after the quantum revolution in (...) physics, or dowe have to abandon it in favor of an objective indeterminism? In light of such reflections, what is the relevant interpretation of probability in evolutionary theory? Do biologists use the concept of probability because they are finite cognitive agents or because the evolutionary process is fundamentally probabilistic? In this paper, I will show that we do not yet fully understand the nature of chance in evolution. (shrink)

I want to exhibit the deeper metaphysical reasons why some common ways of describing the causal role of genes in development and evolution are problematic. Specifically, I show why using the concept of information in an intentional sense in genetics is inappropriate, even given a naturalistic account of intentionality. Furthermore, I argue that descriptions that use notions such as programming, directing or orchestrating are problematic not for empirical reasons, but because they are not strictly causal. They are intentional. By contrast, (...) other notions that are part of the received view in genetics and evolutionary theory are defensible if understood correctly, in particular the idea that genes are the main replicators in evolution. The paper concludes that dropping all intentional or intentionally laden concepts does not force us to accept the so-called causal parity thesis, at least not in its stronger form. (shrink)

Self-locating attitudes and assertions provide a challenge to the received view of mental and linguistic intentionality. In this paper I try to show that the best way to meet this challenge is to adopt relativistic, centred possible worlds accounts for both belief and communication. First, I argue that self-locating beliefs support a centred account of belief. Second, I argue that self-locating utterances support a complementary centred account of communication. Together, these two claims motivate a unified centred conception of belief and (...) communication. (shrink)

It has been claimed that the intentional stance is necessary to individuate behavioral traits. This thesis, while clearly false, points to two interesting sets of problems concerning biological explanations of behavior: The first is a general in the philosophy of science: the theory-ladenness of observation. The second problem concerns the principles of trait individuation, which is a general problem in philosophy of biology. After discussing some alternatives, I show that one way of individuating the behavioral traits of an organism is (...) by a special use of the concept of biological function, as understood in an enriched causal role (not selected effect) sense. On this view, a behavioral trait is essentially a special kind of regularity, namely a regularity that is produced by some regulatory mechanism. Regulatory mechanisms always require goal states, which can only be provided by functional considerations. As an example from actual (as opposed to folk) science, I examine the case of social behavior in nematodes. I show that the attempt to explain this phenomenon actually transformed it. This supports the view that scientific explanation does not explain an explanandum phenomenon that is given prior to the explanation; rather, the explanandum is changed by the explanation. This means that there could be a plurality of stances that have some heuristic value initially, but which will be abandoned in favor of a functional characterization eventually. (shrink)
