The Christian does not live in a vacuum, says the author, but in a world of government, politics, labor, and marriage. Hence, Christian ethics cannot exist in a vacuum what the Christian needs, claims Dietrich Bonhoeffer, is concrete instruction in a concrete situation. Although the author died before completing his work, this book is recognized as a major contribution to Christian ethics. The root and ground of Christian ethics, the author says, is the reality of God as revealed in (...) Jesus Christ. This reality is not manifest in the Church as distinct from the secular world such a juxtaposition of two separate spheres, Bonhoeffer insists, is a denial of God's having reconciled the whole world to himself in Christ. On the contrary, God's commandment is to be found and known in the Church, the family, labor, and government. His commandment permits man to live as man before God, in a world God made, with responsibility for the institutions of that world. (shrink)
Pragmatic pluralism denotes a particular approach to problems of international human rights and protections that departs from conventional cosmopolitan approaches. Pragmatic pluralism argues for situated and localized forms of cooperation between state and non-state actors, particularly religious groups and organizations, that may not share the secular, juridical understandings of rights, persons, and obligations common to contemporary cosmopolitan theory. A resource for the development of such a model of pragmatic pluralism can be found in the work of Hannah Arendt. Arendt's early (...) dissertation "Love and Saint Augustine" affords a model of religious community and obligation that can be read productively alongside her later political writings. The possibilities inherent in a cooperative reading of these two parts of her work can be illustrated in relation to an issue of particular concern to cosmopolitan theorists: the international refugee crisis.

While political philosophers have turned to Hegel’s notion of recognition in their development of a theory of identity politics, a careful reading of the Phenomenology of Spirit, and of the master-servant dialectic in particular, reveals the limits of this approach. For Hegel, recognition cannot be separated from a process of self-determination, which is as essential to the development of genuine autonomy as the affirmation of claims to recognition. This article examines the role of self-determination in the Phenomenology of Spirit and (...) considers its implications for the theorization of contemporary politics. (shrink)

The German theologian and martyr Dietrich Bonhoeffer is not widely known for engaging with scientific thought, having been heavily influenced by Karl Barth's celebrated stance against natural theology. However, during the period of his maturing theology in prison Bonhoeffer read a significant scientific work, Carl Friedrich von Weizsäcker's The World View of Physics. From this he gained two major insights for his theological outlook. First, he realized that the notion of a "God of the gaps" is futile, not (...) just in science but in other areas of human inquiry. Second, he felt that an infinite universe, as considered by science, would be self-subsistent and could exist as if there were no God. Bonhoeffer replaced Barth's radical critique of religion with the even more extreme view that it is a mere passing phase in history that grown-up humanity can dispense with. At the same time Bonhoeffer began an important critique of Barth's reaction, namely, the latter's retreat to a "positivism of revelation." While Bonhoeffer did not go quite as far as one might like, his approach opened up hopeful avenues for an answer to "the liberal question" and even a revived place for some kind of natural theology.

Before being executed by the Nazis at the age of 39, Dietrich Bonhoeffer had produced enough material, according to Howell (1995), to fill 16 volumes of theological reflections. Nevertheless, Howell noted, Dietrich Bonhoeffer is not a household name. That is unfortunate. One of Bonhoeffer's most inspiring efforts-from the perspective of mass media ethics-centered around his unfinished attempt to define "what is meant by telling the truth." As is often the case with truly outstanding thinkers, his reflections in (...) this regard appear even more timely today than when he composed them well over 50 years ago. (shrink)
The struggle that prompted Bonhoeffer’s “unconscious Christianity” offers a concrete illustration of the commonsensical in Rahner’s “anonymous Christian.” Thus Rahner’s theory adds theological coherence to what Bonhoeffer intuited. While Bonhoeffer faced the seeming ineffectiveness of Jesus’ teaching for the majority of Christians in Germany, Rahner faced his church’s view of Augustine’s “massa damnata” through a reexamination of church mission and theological categories. In both theologians, Jesus the God-man is the symbol of God’s communion with “the human” in (...) God’s care for all peoples. The article concludes by asking whether the advent of such Christologies signals an approaching time of greater humility with regard to the Christian path to salvation. (shrink)
The theology of Dietrich Bonhoeffer, which is deeply rooted in classical Christology and Lutheran orthodoxy, has close affinities with views about the nature of God and God’s relationship with the world that has recently been labeled “open theism.” Bonhoeffer’s concepts of God, freedom, providence and ethics provide relational views of God with firm theological credentials and exemplify a strong integration of philosophy and theology.
This paper examines Heidegger’s account of the proper relation between philosophy and theology, and Dietrich Bonhoeffer’s critique thereof. Part I outlines Heidegger’s proposal for this relationship in his lecture “Phenomenology and Theology,” where he suggests that philosophy might aid theology by means of ‘formal indication.’ In that context Heidegger never articulates what formal indication is, so Part II exposits this obscure notion by looking at its treatment in Heidegger’s early lecture courses, as well as its roots in Husserl. Part (...) III presents Bonhoeffer’s theological response, which challenges Heidegger’s attempt to maintain a neutral ontology that remains unaffected by both sin and faith. (shrink)
This paper attempts to read Bonhoeffer’s work as a whole. I maintain that Bonhoeffer’s attempt to develop a distinctly Christian version of the Hegelian concept of objective spirit is the central concern of his Sanctorum Communio. I note the ways he continues to refine and clarify that concept in later works, even as it remainsunnamed. I then argue that by the time of the Letters and Papers from Prison, developing this concept has become Bonhoeffer’s overriding project. I (...) conclude by suggesting ways that the earlier works already provide resources for answering the probing questions of the Letters and Papers. (shrink)
Though Bonhoeffer is usually thought to have been one of the architects of modern theology, he was also one of modernity's most penetrating critics. The author lays out Bonhoeffer's challenges to certain cherished modern assumptions by examining (1) his linkage of totalitarianism to the political utopianism that arose out of the French Revolution, (2) his fear of the nihilistic implications of the rationalists' notion of the sovereign self and of the modern tendency to view life as an end (...) in itself, and (3) his suspicion of all forms of moral absolutism, including the Kantian absolutizing of the duty to tell the truth. What emerges is a picture of Bonhoeffer as a theologian who coupled a keen sense of our creatureliness and limitation with a resolute belief in the activity of God in history, and of Bonhoeffer as an ethicist who generated a Christian relational ethics that offers an alternative to both the ethics of abstract principle and the ethics of intuitive situational response.

In Dietrich Bonhoeffer's Ethics the notion of reality plays a central role. The present article focuses on the ethical implications of the Chalcedonian Christology underlying this concept. This approach is tied to the debate on the relationship between the universal and specific identity of Christian social ethics in public discourse. In the opening section the article outlines the pertinence of this debate with regard to Bonhoeffer's Christological ethic. In the following section the article analyzes Bonhoeffer's concept of (...) reality and the implied Chalcedonian traits. With this foundation established the article raises the question about its social ethical implications. The final part of the article argues that Bonhoeffer's ethics and ecclesiology cannot be separated from each other, explaining why Bonhoeffer's notion of reality leads to an assertion of the church's role in letting reality become real. In the light of Bonhoeffer's notion of reality the last section argues for the reconciliation of Christian witness and participation in public discourse. (shrink)
The work of René Girard invites us to re-imagine a ‘religious–secular’ interactivity within social space in a way released from the violent dualisms of the ‘sacred/profane.’ Earlier Dietrich Bonhoeffer considered the same task and suggested directions for a positive theology of church-state relations, even as the inherited forms of these institutions were collapsing about him. This paper explores the Girardian scenario for church and state becoming rivalrous ‘doubles’– whether it be secular utopic projects doubling religious narratives of redemption, or (...) churches doubling the state as parallel yet purer societies – and suggests resources from Bonhoeffer by which a non-rivalrous church-state relationality - both mutually-constituting and mutually-limiting - may be configured.

On one level this is a case study in science, religion, and morality, with special attention to the consequences for morality of science's embeddedness in society. On another level this is the science-and-theology dialogue between the theologian Dietrich Bonhoeffer and his brother Karl-Friedrich, a physicist. The influence of Karl-Friedrich and the brothers' exchanges on Dietrich's prison theology receives special attention. Because this study is set in Germany in the 1930s and 40s, and Karl-Friedrich's work intersected Germany's efforts to develop (...) a nuclear weapon, the discussion leads to Los Alamos and the Manhattan Project. The attention there is to the interplay of science, religion, and morality at the time the bomb was detonated at the Trinity site. (shrink)
Dietrich Bonhoeffer's thinking about ethics and Christianity is a fascinating attempt to combine different, and often conflicting, strands in the Christian intellectual tradition. In this article, I outline his thinking, analyse the advantages and disadvantages in his approach, and relate it to developments in contemporary philosophy. His critique of an excessive stress upon principles and abstraction in opposition to a concern for concrete circumstances is, I argue, best seen as a necessary critique of what I call moralism rather than (...) morality. It is also related to recent philosophical theories of particularism and the debates about ‘emergency ethics’ in current philosophy. On the negative side, Bonhoeffer has a tendency to treat non-Christian ethics as necessarily relativist and at times is excessively influenced by the elements in Christian theological tradition that are hostile to the natural and to non-Christian philosophy. In addition, his invocation of ‘the Divine mandates’ seems to have undesirable implications for some genuine values in liberal democratic theory and practice. (shrink)

Cicero's Topica is one of the canonical texts on ancient rhetorical theory. This is the first full-scale commentary on this work, and the first critical edition that is informed by a full analysis of its transmission.

The introduction and the commentary seek to elucidate the exact origins of the theory of argument used by Cicero and explain how it works. Moreover, since Cicero's suggestions for a reform of (...) Roman civil law have parallels in similar efforts within the legal profession, Tobias Reinhardt considers how much common ground there is between Cicero and the jurists. (shrink)

This paper argues that ‘that’-clauses are not singular terms (without denying that their semantical values are propositions). In its first part, three arguments are presented to support the thesis, two of which are defended against recent criticism. The two good arguments are based on the observation that substitution of ‘the proposition that p’ for ‘that p’ may result in ungrammaticality. The second part of the paper is devoted to a refutation of the main argument for the claim that ‘that’-clauses are (...) singular terms, namely that this claim is needed in order to account for the possibility of quantification into ‘that’-clause position. It is shown that not all quantification in natural languages is quantification into the position of singular terms, but that there is also so-called ‘non-nominal quantification’. A formal analysis of non-nominal quantification is given, and it is argued that quantification into ‘that’-clause position can be treated as another kind non-nominal quantification. (shrink)
Jason Stanley and Timothy Williamson have argued that there is no fundamental distinction between what Gilbert Ryle famously called 'knowing how' and 'knowing that', and that the former can be treated as a special kind of the latter. I will endeavour to show that sentences of the form 'a knows how to F' are ambiguous between a reading in which we ascribe knowledge-that to a and another in which we ascribe something to a which is irreducible to any kind of (...) knowledge-that and can most appropriately be characterized as an ability. The authors' attempt to reduce also the latter reading to an ascription of knowledge-that fails because it rests on an unexplained conception of practical modes of presentation. (shrink)
This thesis is about the conceptualization of persistence of physical, middle-sized objects within the theoretical framework of the revisionary ‘B-theory’ of time. According to the B-theory, time does not flow, but is an extended and inherently directed fourth dimension along which the history of the universe is ‘laid out’ once and for all. It is a widespread view among philosophers that if we accept the B-theory, the commonsensical ‘endurance theory’ of persistence will have to be rejected. The endurance theory says (...) that objects persist through time by being wholly present at distinct times as numerically the same entity. Instead of endurantism, it has been argued, we have to adopt either ‘perdurantism’ or the ‘stage theory’. Perdurantism is the theory that objects are four-dimensional ‘space-time worms’ persisting through time by having distinct temporal parts at distinct times. The stage theory says that objects are instantaneous temporal parts (stages) of space-time worms, persisting by having distinct temporal counterparts at distinct times. In the thesis, it is argued that no good arguments have been provided for the conclusion that we are obliged to drop the endurance theory by acceptance of the B-theory. This conclusion stands even if the endurance theory incorporates the claim that objects endure through intrinsic change. It is also shown that perdurantism and the stage theory come with unwelcome consequences. -/- Paper I demonstrates that the main arguments for the view that objects cannot endure in B-time intrinsically unchanged fail. Papers II and III do the same with respect to the traditional arguments against endurance through intrinsic change in B-time. Paper III also contains a detailed account of the semantics of the tenseless copula, which occurs frequently in the debate. The contention of Paper IV is that four-dimensional space-time worms, as traditionally understood, are not suited to take dispositional predicates. In Paper V, it is shown that the stage theory needs to introduce an overabundance of persistence-concepts, many of which will have to be simultaneously applicable to a single object (qua falling under a single sortal), in order for the theory to be consistent. The final article, Paper VI, investigates the sense in which persistence can, as is sometimes suggested, be a ‘conventional matter’. It also asks whether alleged cases of ‘conventional persistence’ create trouble for the endurance theory. It is argued that conventions can only enter at a trivial semantic level, and that the endurance theory is no more threatened by such conventions than are its rivals. (shrink)
What exactly do we do when we try to make sense of other people e.g. by ascribing mental states like beliefs and desires to them? After a short criticism of Theory-Theory, Interaction Theory and the Narrative Theory of understanding others as well as an extended criticism of the Simulation Theory in Goldman's recent version (2006), we suggest an alternative approach: the Person Model Theory . Person models are the basis for our ability to register and evaluate persons having mental as (...) well as physical properties. We argue that there are two kinds of person models, nonconceptual person schemata and conceptual person images , and both types of models can be developed for individuals as well as for groups.

Of course there is a long history of such sayings in all the world’s main spiritual traditions. Socrates’ remark reminds us at once of Solon’s doleful doctrine that we should call no man happy until he is dead (Herodotus Histories Book 1; Aristotle Nicomachean Ethics 1100a11). And Bonhoeffer’s famous saying, while it echoes the typical teaching of many Christian spiritual masters, for instance St Thomas à Kempis and Bianco da Siena (the author of that beautiful hymn “Come down O (...) Love Divine”), is ultimately just a paraphrase of Jesus’ even more famous saying that anyone who wants to follow him must “deny himself, and take up his cross, and follow me” (Matthew 16.24).

This paper asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since there are strong reasons for thinking that such conventionality is impossible, it is desirable that our metaphysical-cum-semantic (...) theories of persistence be able to account for such scenarios in terms of conventions of the first kind. Later parts of the article therefore investigate whether three of the currently most influential metaphysical-cum-semantic theories of persistence—the endurance theory, the stage theory, and the perdurance theory—can do this. Fortunately, for them, it turns out that all can, though some philosophers have disputed this. However, when we ask how they account for a typical case of “conventional persistence” some problematic features of the theories—having to do with reference, persistence conditions, how they relate, and the epistemology of persistence—are revealed.

This paper intends to show that Aquinas gives a non-deterministic account of free decision. Angelic sin is the eminent test case: ex hypothesi, angels are supremely intelligent and not subject to ignorance, passions, or negatively disposing habits. Nothing predetermines their choice; rather it ultimately depends on their freedom alone. All angels acted based upon reasons, but why certain angels acted for an inadequate reason whereas others for an adequate reason cannot be fully explained. Thomas's action theory allows him to (...) explain angelic choice as contingent and selfdetermined. The salient features of this explanation are transferable to human free decision. (shrink)
In this paper I explore how the tenseless copula is to be interpreted in sentences of the form “ a is F at t ”, where “ a ” denotes a persisting, changeable object, “ F ” stands for a prima facie intrinsic property and “ t ” for a B-time. I argue that the interpretation of the copula depends on the logical role assigned to the time clause. Having rejected the idea that the time clause is to be treated (...) as a sentence operator, I argue: (1) that if “at t ” is thought of as being associated with “ a ” or “ F ”, then the tenseless copula is most plausibly read as an “is” simpliciter ; and (2) that if “at t ” is treated as being associated with the copula, then the tenseless copula is most plausibly understood as expressing a disjunction of tensed copulas. I end the paper by explaining the importance of the issue. I indicate the ramifications interpretation of the tenseless copula has for the so-called problem of temporary intrinsics. (shrink)
An alternative to the standard endurance/perdurance accounts of persistence has recently been developed: the stage theory (Sider, T. Four-Dimensionalism: an Ontology of Persistence and Time. Oxford: Oxford University Press, 2001; Hawley, K. How Things Persist. Oxford: Oxford University Press, 2001). According to this theory, a persisting object is identical with an instantaneous stage (temporal part). On the basis of Leibniz's Law, I argue that stage theorists either have to deny the alleged identity (i.e., give up their central thesis) or hold (...) that stages are both instantaneous and continuants. I subsequently show that, although stage theory is flexible enough to accommodate the latter claim, the cost for accommodating it is an excessive proliferation of persistence concepts. (shrink)
This article re-examines Ned Block‘s ( 1997 , 2007 ) conceptual distinction between phenomenal consciousness and access consciousness. His argument that we can have phenomenally conscious representations without being able to cognitively access them is criticized as not being supported by evidence. Instead, an alternative interpretation of the relevant empirical data is offered which leaves the link between phenomenology and accessibility intact. Moreover, it is shown that Block’s claim that phenomenology and accessibility have different neural substrates is highly problematic in (...) light of empirical evidence. Finally, his claim that there can be phenomenology without cognitive accessibility is at odds with his endorsement of the 'same-order-theory' of consciousness. (shrink)
Abstract The subjectivity of conscious experience is a central feature of our mental life that puzzles philosophers of mind. Conscious mental representations are presented to me as mine, others remain unconscious. How can we make sense of the difference between them? Some representationalists (e.g. Tye) attempt to explain it in terms of non-conceptual intentional content, i.e. content for which one need not possess the relevant concept required in order to describe it. Hanna claims that Kant purports to explain the subjectivity (...) of conscious experience in this way. This paper examines this claim in some detail in the context of a more general criticism of this kind of attempt to explain subjectivity and proposes a different reading of Kant that also leads to an alternative account of subjectivity independent from content.

Tobias Hansson Wahlberg argues in a recent article (2009) that the truth of “Hesperus is Phosphorus” depends on the assumption that the endurance theory of persistence is true. The statement is not true (or at least can reasonably be doubted), he argues, if one assumes (a) the theory of persistence according to which objects are four-dimensional entities, persisting through perdurance, i.e. by having temporal parts that are numerically distinct, and (b) the thesis of unrestricted mereological composition (UMC), that is, (...) that any two things, however scattered in space or time, compose a sum.

This paper identifies an overdetermination problem faced by the non-reductive dispositional property account of disposition ascriptions. Two possible responses to the problem are evaluated and both are shown to have serious drawbacks. Finally it is noted that the traditional conditional analysis of dispositional ascriptions escapes the original difficulty.
Two recurrent arguments levelled against the view that enduring objects survive change are examined within the framework of the B-theory of time: the argument from Leibniz's Law and the argument from Instantiation of Incompatible Properties. Both arguments are shown to be question-begging and hence unsuccessful.
One of the older questions in the debate about Corporate Social Responsibility (CSR) is whether it is worthwhile for organizations to pay attention to societal demands. This debate was emotionally, normatively, and ideologically loaded. Up to the present, this question has been an important trigger for empirical research in CSR. However, the answer to the question has apparently not been found yet, at least that is what many researchers state. This apparent ambivalence in CSR consequences invites a literature study that (...) can clarify the debate and allow for the drawing of conclusions. The results of the literature study performed here reveal that there is indeed clear empirical evidence for a positive correlation between corporate social and financial performance. Voices that state the opposite refer to out-dated material. Since the beginnings of the CSR debate, societies have changed. We can therefore clearly state that, for the present Western society, “Good Ethics is Good Business.”. (shrink)
A central method within analytic philosophy has been to construct thought experiments in order to subject philosophical theories to intuitive evaluation. According to a widely held view, philosophical intuitions provide an evidential basis for arguments against such theories, thus rendering the discussion rational. This method has been the predominant way to approach theories formulated as conditional or biconditional statements. In this paper, we examine selected theories of musical expressivity presented in such logical forms, analyzing the possibilities for constructing thought experiments (...) against them. We will argue that philosophical intuitions are not available for the evaluation of the types of counterarguments that would need to be constructed. Instead, the evaluation of these theories, to the extent that it can succeed at all, will centrally rely on inferential, non-immediate access to our subjective musical experiences. Furthermore, attempted thought experiments lose their methodological function because no proper distinction can be drawn between the persons figuring in the thought-experimental scenario and the evaluator of the scenario. Consequently, some of the central contributions to what is generally understood to be analytic philosophy of art are shown to represent a form of aesthetic criticism, offering much less basis for rational argumentation than is often thought.

There is increasing evidence for epigenetically mediated transgenerational inheritance across taxa. However, the evolutionary implications of such alternative mechanisms of inheritance remain unclear. Herein, we show that epigenetic mechanisms can serve two fundamentally different functions in transgenerational inheritance: (i) selection-based effects, which carry adaptive information in virtue of selection over many generations of reliable transmission; and (ii) detection-based effects, which are a transgenerational form of adaptive phenotypic plasticity. The two functions interact differently with a third form of epigenetic information transmission, (...) namely information about cell state transmitted for somatic cell heredity in multicellular organisms. Selection-based epigenetic information is more likely to conflict with somatic cell inheritance than is detection-based epigenetic information. Consequently, the evolutionary implications of epigenetic mechanisms are different for unicellular and multicellular organisms, which underscores the conceptual and empirical importance of distinguishing between these two different forms of transgenerational epigenetic effect.

Disposition ascription has been discussed a good deal over the last few decades, as has the revisionary metaphysical view of ordinary, persisting objects known as 'fourdimensionalism'. However, philosophers have not merged these topics and asked whether four-dimensional objects can be proper subjects of dispositional predicates. This paper seeks to remedy this oversight. It argues that, by and large, four-dimensional objects are not suited to take dispositional predicates.
It is argued that philosophers who adopt the perdurance theory of persistence and who subscribe to the principle of Unrestricted Mereological Composition (UMC) are in a position to regard “Phosphorus is Hesperus” as false.
A virtual particle is an elementary particle in a quantum field theory that serves to symbolise the interaction of its counterparts, the so called real particles. In the last 20 years, philosophers of physics have put forth several arguments for and against an interpretation of virtual particles as being like ordinary objects in space and time. In this article, I will attempt to systematise the major arguments and argue that no pro-argument is ultimately satisfactory, and that only one contra-argument—that of (...) superposition—is sufficient to deny the realistic interpretation of virtual particles. The secondary aim of this paper is to argue that even the philosophical considerations of virtual particles overestimate their role in that these entities are merely pictorial descriptions of a mathematical approximation method. This description, while helpful, is not necessary to understand particle interactions. In the end, quantum field theory is not the place to explain what actually happens in the very centre of an individual particle interaction. (shrink)
In classroom teaching, material objects like the blackboard play an important role. Yet qualitative research on education has largely ignored this material dimension of education and focused on interaction and discourse. Both dimensions are, however, closely related to each other. Material objects are embedded in classroom discourse and are transformed into knowledge objects by speech acts, and in turn structure discussions and constitute a point of reference for school lessons. Drawing on ethnographic research on classroom lessons in mathematics and science (...) classes in German high schools, we propose a perspective that recognizes both the materiality of teaching and its interactive dimension.

The paper tries to shed new exegetical light on Frege's "Dialogue with Pünjer on Existence" by showing that Pünjer's position in the dialogue is strongly inspired by Kantian claims about existence. It is argued that Pünjer's wavering between a broadly Meinongian and a broadly Fregean view on existence can be explained by the fact that there are Kantian remarks which seem to speak in favour of each of these views. A suggestion is then made how Kant's claims can be interpreted (...) in such a way that the tension which they seem to entail disappears. (shrink)
This paper tries to read some structure into the perplexing diversity of the literature on Heidegger’s concept of authenticity. It argues that many of the interpretations available rely on views that are false and cannot be Heidegger’s. It also shows that the only correct interpretation of Heidegger’s concept of authenticity emerges from a synthesis of Dreyfus’ later interpretation and Haugeland’s interpretation of this concept. A synthesis of these interpretations yields an interpretation, according to which Dasein’s being is authentic only if (...) it is capable of using tools or language in radically new ways. (shrink)
