The debate on the conventionality of simultaneity and the debate on the dimensionality of the world have been central in the philosophy of special relativity. The link between both debates however has rarely been explored. The purpose of this paper is to gauge what implications the former debate has for the latter. I show the situation to be much more subtle than was previously argued, and explain how the ontic versus epistemic distinction in the former debate impacts the latter. Despite (...) claims to the contrary, I conclude that special relativity leaves the debate on the dimensionality of the world underdetermined. (shrink)

The heated debates and severe conflicts between the atomists and the anti-atomists of the latter half of the nineteenth century are well known to the historian of science. The position of Dmitrii Ivanovich Mendeleev towards these nineteenth century debates on atomism will be studied in this paper. A first attempt will thus be offered to reconcile Mendeleev’s seemingly contradictory comments and ambiguous standpoints into one coherent view.

The aim of this doctoral dissertation is to closely explore the nature of Einstein’s block universe and to tease out its implications for the nature of time and human freedom. Four questions, in particular, are central to this dissertation, and set out the four dimensions of this philosophical investigation: (1) Does the block universe view of time follow inevitably from the theory of special relativity? (2) Is there room for the passage of time in the block universe? (3) Can we (...) distinguish past from future in the block universe? (4) Is there room for human freedom in the block universe? Although the answer of most philosophers would be yes, triple no, my own answer, controversially, is no, triple yes. -/- I thereby challenge the status quo with respect to each of these metaphysical questions, and argue that none of these questions can be answered from looking at physics alone. Physics may constrain our metaphysics, but it certainly does not settle it. What is needed in order to answer these questions, are additional metaphysical assumptions that fall outside the scope of modern physics. My primary goal in this dissertation, therefore, is not to settle the debates on the nature of time and human freedom, but to clarify them by expliciting the metaphysical assumptions that are otherwise left implicit.

Human freedom is in tension with nomological determinism and with statistical determinism. The goal of this paper is to answer both challenges. Four contributions are made to the free-will debate. First, we propose a classification of scientific theories based on how much freedom they allow. We take into account that indeterminism comes in different degrees and that both the laws and the auxiliary conditions can place constraints. A scientific worldview pulls towards one end of this classification, while libertarianism pulls towards (...) the other end of the spectrum. Second, inspired by Hoefer, we argue that an interval of auxiliary conditions corresponds to a region in phase space, and to a bundle of possible block universes. We thus make room for a form of non-nomological indeterminism. Third, we combine crucial elements from the works of Hoefer and List; we attempt to give a libertarian reading of this combination. On our proposal, throughout spacetime, there is a certain amount of freedom that can be interpreted as the result of agential choices. Fourth, we focus on the principle of alternative possibilities throughout and propose three ways of strengthening it. (shrink)

This review paper provides a detailed overview and critical analysis of the philosophical literature on the Rietdijk–Putnam–Maxwell argument for the four-dimensionality of the world. After briefly introducing the debate on the dimensionality of the world, I present the arguments by Rietdijk, Putnam and Maxwell, and highlight the differences between them. I subsequently raise a total of eleven objections against the Rietdijk–Putnam–Maxwell argument, and conclude that its validity is underdetermined by the formalism of special relativity.

The block universe theory of time is commonly said to be incompatible with temporal becoming. This confuses Maudlin who upholds both eternalism and passage. The aim of this paper is to answer Maudlin’s plea for clarification by distinguishing four degrees of temporal becoming. After discussing their respective compatibility with the block universe, I show that Maudlin asks much less from temporal becoming than most philosophers of time. Consequently, his form of becoming is compatible with the block universe, whereas the stronger (...) forms of becoming are not. (shrink)

At the heart of chemistry lies the periodic system of chemical elements. Despite being the cornerstone of modern chemistry, the overall structure of the periodic system has never been fully understood from an atomic physics point of view. Group-theoretical models have been proposed instead, but they suffer from several limitations. Among others, the identification of the correct symmetry group and its decomposition into subgroups has remained a problem to this day. In an effort to deepen our limited understanding of the (...) periodic law, we have extended the traditional Lie algebraic framework to account for the peculiar degeneracy structure of the periodic system. Starting from the four-dimensional hidden symmetry and accidental degeneracy of the hydrogen atom, as first revealed by Fock in 1935, our research has mainly focussed on the way this SO(4) symmetry of the Coulomb potential gets broken in the periodic system as a consequence of the transformation of the hydrogenic (n, l) filling order to the Madelung (n+l, n) order due to electronic repulsions, relativistic effects and spin-orbit couplings. In this PhD dissertation, a new left-step format of the periodic table is first proposed on the basis of the Madelung rule. Following the particle physics tradition, the chemical elements are then considered as various states of some 'atomic matter', which is described by a non-compact spectrum-generating dynamical Lie group. The chemical elements are shown to form a basis for a single infinite-dimensional degeneracy space of the SO(4,2) ⊗ SU(2) group. An explanation for the period doubling is then proposed in terms of a particular symmetry breaking of the SO(4,2) group to the anti de Sitter SO(3,2) group. The Madelung rule is rationalised on the basis of nonlinear Lie algebras which reflect the screening of the Coulomb hole. This opens new perspectives for a symmetry-based understanding of how the periodic law emerges from its quantum mechanical foundations, and holds the future promise of complementing our current phenomenological approach by a direct atomic physics approach.

This chapter gives an overview of the evolution of the position of the rare-earth elements in the periodic system, from Mendeleev’s time to the present. Three fundamentally different accommodation methodologies have been proposed over the years. Mendeleev considered the rare-earth elements as homologues of the other elements. Other chemists looked upon the rare earths as forming a special intraperiodic group and therefore clustered the rare-earth elements in one of the groups of the periodic table. Still others adhered to the intergroup (...) accommodation of the rare earths, according to which the rare-earth elements do not show any relationship with the other elements, so that they had to be placed within the periodic table as a separate family of elements. The intergroup accommodation became the preferred one in the twentieth century. The advantages and disadvantages of the different representations of the modern periodic table are discussed. (shrink)

According to Leininger, presentists and growing blockers cannot explain why past and present regularities persist in the future. In order to do so, they would have to appeal to enforcers, such as causation, laws or dispositions. But in a world with no future, these enforcers are powerless and cannot guarantee future regularity. I disagree and argue that Leininger’s coordination problem can be met by distinguishing type- from token-level necessitation. Whereas token-level necessitation is cross-temporal and subject to Leininger’s coordination problem, type-level (...) necessitation is atemporal and immune to the coordination problem. For this solution to work, though, type-level necessitation must be ontologically prior to token-level necessitation. This forces us to adopt a Platonist position according to which universals are transcendent, and not immanent. (shrink)

To this day, a hundred and fifty years after Mendeleev's discovery, the overal structure of the periodic system remains unaccounted for in quantum-mechanical terms. Given this dire situation, a handful of scientists in the 1970s embarked on a quest for the symmetries that lie hidden in the periodic table. Their goal was to explain the table's structure in group-theoretical terms. We argue that this symmetry program required an important paradigm shift in the understanding of the nature of chemical elements. The (...) idea, in essence, consisted of treating the chemical elements, not as particles, but as states of a superparticle. We show that the inspiration for this came from elementary particle physics, and in particular from Heisenberg's suggestion to treat the proton and neutron as different states of the nucleon. We provide a careful study of Heisenberg's last paper on the nature of elementary particles, and explain why the Democritean picture of matter no longer applied in modern physics and a Platonic symmetry-based picture was called for instead. We show how Heisenberg's Platonic philosophy came to dominate the field of elementary particle physics, and how it found its culmination point in Gell-Mann's classification of the hadrons in the eightfold way. We argue that it was the success of Heisenberg's approach in elementary particle physics that sparked the group-theoretical approach to the periodic table. We explain how it was applied to the set of chemical elements via a critical examination of the work of the Russian mathematician Abram Ilyich Fet the Turkish-American physicist Asim Orhan Barut, before giving some final reflections.

When it comes to evaluating reductive hypotheses in metaphysics, supervenience arguments are the tools of the trade. Jaegwon Kim and Frank Jackson have argued, respectively, that strong and global supervenience are sufficient for reduction, and others have argued that supervenience theses stand in need of the kind of explanation that reductive hypotheses are particularly suited to provide. Simon Blackburn's arguments about what he claims are the specifically problematic features of the supervenience of the moral on the natural have also been (...) influential. But most discussions of these arguments have proceeded under the strong and restrictive assumptions of the S5 modal logic. In this paper we aim to remedy that defect, by illustrating in an accessible way what happens to these arguments under relaxed assumptions and why. The occasion is recent work by Ralph Wedgwood, who seeks to defend non-reductive accounts of moral and mental properties together with strong supervenience, but to evade both the arguments of Kim and Jackson and the explanatory challenge by accepting only the weaker, B, modal logic. In addition to drawing general lessons about what happens to supervenience arguments under relaxed assumptions, our goal is therefore to shed some light on both the virtues and costs of Wedgwood's proposal.

In this essay, Johannes Giesinger comments on the current philosophical debate on educational justice. He observes that while authors like Elizabeth Anderson and Debra Satz develop a so-called adequacy view of educational justice, Harry Brighouse and Adam Swift defend an egalitarian principle. Giesinger focuses his analysis on the main objection that is formulated, from an egalitarian perspective, against the adequacy view: that it neglects the problem of securing fair opportunities in the competition for social rewards. Giesinger meets this objection (...) by expressing two basic theses: First, he argues that Brighouse and Swift themselves fail to give an adequate account of fair competition; and, second, he shows that the adequacy view provides the theoretical resources to face this problem.

The Newman problem is a fundamental problem that threatens to undermine structural assumptions and structural theories throughout philosophy and science. Here, we consider the problem in the context of consciousness science. We introduce and discuss the problem, and explain why it is detrimental not only to structuralist assumptions, but also to theories of consciousness, if left unconsidered. However, we show that if phenomenal spaces, and mathematical structures of conscious experience more generally, are understood in the right way, the Newman problem (...) does not arise. The upshot of our paper is that consciousness science needs to be careful in which definition of structure to consider, but if it is, the Newman problem disappears. (shrink)

Informally, structural properties of mathematical objects are usually characterized in one of two ways: either as properties expressible purely in terms of the primitive relations of mathematical theories, or as the properties that hold of all structurally similar mathematical objects. We present two formal explications corresponding to these two informal characterizations of structural properties. Based on this, we discuss the relation between the two explications. As will be shown, the two characterizations do not determine the same class of mathematical properties. (...) From this observation we draw some philosophical conclusions about the possibility of a ‘correct’ analysis of structural properties. (shrink)

The term ‘identity politics’ is used to refer to a wide range of political movements. In this paper, we look at the theoretical ideas underpinning two strongly, mutually opposed forms of identity politics, and identify some crucial differences between them. We critically compare the identitarian ideology of the New Right with feminist standpoint theory, focusing on two issues: relativism and essentialism. In carrying out this critical comparison we illuminate under-theorized aspects of both new right identitarianism and standpoint theory; demonstrate how (...) the two are distinct; reveal the depth and pervasiveness of the new right ideology’s flaws; and show what a coherent left-wing identity politics could look like.

The question of what the function of human remembering might be has entered the contemporary philosophical discourse only relatively recently. In this debate, two main views have emerged: preservatism and simulationism. According to preservatism, the function of remembering is to preserve information from/about the past. In contrast, simulationism holds that the function of remembering is to enable reliable thought about the future. Here, I employ form to function reasoning to evaluate both of these views. I argue that both perservatism and (...) simulationism fail to account for the entire representational structure of episodic remembering. As an alternative, I then propose my own account: that the function of remembering is to track when we have epistemic authority about the past. (shrink)

This is, to the best of my knowledge, the first published attempt at a rigorous logical formalization of a passage in Leibniz's Monadology. The method we followed was suggested by Johannes Czermak.

This is part one of a two-part paper, in which we develop an axiomatic theory of the relation of partial ground. The main novelty of the paper is the of use of a binary ground predicate rather than an operator to formalize ground. This allows us to connect theories of partial ground with axiomatic theories of truth. In this part of the paper, we develop an axiomatization of the relation of partial ground over the truths of arithmetic and show that (...) the theory is a proof-theoretically conservative extension of the theory PT of positive truth. We construct models for the theory and draw some conclusions for the semantics of conceptualist ground. (shrink)

Debates on Nietzsche’s naturalism usually posit nature and culture as competing principles to understand the contingent genesis of humanity. In contrast to this polarizing tendency, I argue that Nietzsche focuses on the cultural characteristics of humanity because of his naturalistic framework. Moreover, I submit that Nietzsche’s conceptualization of the entanglement of nature and culture contains important insights for critically understanding the challenges of the Anthropocene today.

Computational functionalism posits that consciousness is a computation. Here we show, perhaps surprisingly, that it cannot be a Turing computation. Rather, computational functionalism implies that consciousness is a novel type of computation that has recently been proposed by Geoffrey Hinton, called mortal computation.

Living organisms are exposed to numerous influencing factors. This holds also true for their infrastructures that are processing and transducing information like endocrine networks or nerval channels. Therefore, the ability to compensate for noise is crucial for survival. An efficient mechanism to neutralise disturbances is instantiated in form of parallel complementary communication channels exerting antagonistic effects at their common receivers. Different signal processing types share the ability to suppress noise, to widen the system’s regulation capacity, and to provide for variable (...) gains while leaving the transferred signal to a large extent unchanged.

In this paper, I examine two exemplary replies to the challenge of history that played a crucial role in the controversies on the nature and purpose of philosophy during the so-called long 19th century. Nietzsche and Dilthey developed concepts of philosophy in contrast with one another, and in particular regarding their approach to the history of philosophy. While Nietzsche advocates a radical break with the history of philosophy, Dilthey emphasizes the continuity with the philosophical tradition. I shall argue that these (...) conceptual reorientations are linked to specific social images of the philosopher. Nietzsche, on the one hand, presents us a new version of the philosophical recluse. Dilthey, on the other hand, embraces the idea of a philosophical community, thus emphasizing the collective character of philosophical research. My examination of these connections attempts to show that the history of philosophy should also be studied as a social tradition. (shrink)

Several authors have recently questioned whether dehumanization is a psychological prerequisite of mass violence. This paper argues that the significance of dehumanization in the context of National Socialism can be understood only if its ideological dimension is taken into account. The author concentrates on Alfred Rosenberg’s racist doctrine and shows that Nazi ideology can be read as a political anthropology that grounds both the belief in the German privilege and the dehumanization of the Jews. This anthropological framework combines biological, cultural (...) and metaphysical aspects. Therefore, it cannot be reduced to biologism. This new reading of Nazi ideology supports three general conclusions: First, the author reveals a complex strategy of dehumanization which is not considered in the current psychological debate. Second, the analysis of the ideological mechanism suggests a model of dehumanization that is more plausible than other psychological models. Third, the author provides evidence that this kind of dehumanization had psychological consequences and hence was an important feature of Nazi reality. (shrink)

This chapter explores the ideological dimension of dehumanization in the context of National Socialism, focusing on the connection between concepts of humanity and dehumanizing images. NS regarded itself as a political revolution, realizing a new concept of humanity. Nazi ideologues undergirded the self-understanding of NS by developing racist anthropologies. I examine two major strands of Nazi ideology, focusing on their diverging strategies of dehumanization, and arguing that they were dependent on different anthropological frameworks. Richard Walther Darré held a naturalistic concept (...) of humanity and advanced biologistic forms of dehumanization. Alfred Rosenberg developed a dualistic anthropology that combined metaphysical and natural features. He dehumanized certain groups of people by reducing them to being human in a natural sense only. Moreover, I aim to show that the key motifs of these racist worldviews were prevalent in the scientific and philosophical debates on anthropology in early-twentieth-century Germany. I thus explore the general orientation of both the naturalistic and the anti-naturalistic strand in anthropological thought, unfold the animalizing tendencies of these views, and emphasize their conformity with the key motifs of Nazi ideology. The case of NS should thus exemplify the dehumanizing potential of anthropological theories. (shrink)

We live in times of an increasing polarization in which the margins of the political spectrum begin to dominate our social imagination again. While the neoliberal iteration of the capitalist project suggests an extreme individualism as the normative default position, the devastating impact of the globalized economy on many has reignited the pursuit of socialist alternatives. In this constellation, Simmel’s social theory of modernity can be a useful resource to undercut the return of the old battle between opposite economic systems. (...) This paper argues that two kinds of pluralism can be derived from his conceptualization of the social effects of the money economy. In contrast to one-size-fits-all concepts of freedom, Simmel embraces a social pluralism which acknowledges a plurality of cultural spheres as relevant for the self-actualization of modern individuals, attributing different combinations of independence and embeddedness to them. Moreover, he rejects the social extremes of socialism and individualism, since they fail to properly integrate individual freedom into the social whole without undermining it. Instead Simmel gives us the vision of a pluralist economy in which democratic worker’s cooperatives are combined with an overall liberal market to satisfy both the longing for community and the strive for individual distinction.

This is part two of a two-part paper in which we develop an axiomatic theory of the relation of partial ground.

We show that our theory is (...) a proof-theoretically conservative extension of the ramified theory of positive truth up to. (shrink)

This paper examines a looming reproducibility crisis in the core of the hard sciences. Namely, it concentrates on molecular modeling and simulation (MMS), a family of methods that predict properties of substances through computing interactions on a molecular level and that is widely popular in physics, chemistry, materials science, and engineering. The paper argues that in order to make quantitative predictions, sophisticated models are needed which have to be evaluated with complex simulation procedures that amalgamate theoretical, technological, and social factors (...) – leading to problems with reproducibility. Thus, for methodological reasons, the predictive success causes a reproducibility problem. (shrink)

The asylum system faces problems on two fronts. States undermine it with populist politics, and migrants use it to satisfy their migration preferences. To address these problems, asylum services should be commodified. States should be able to pay other states to provide determination and protection-elsewhere. In this article, I aim to identify a way of implementing this idea that is both feasible and desirable. First, I sketch a policy proposal for a commodification of asylum services. Then, I argue that this (...) policy proposal is not only compatible with the right to asylum, but also supported by moral considerations. Despite some undesirable moral features, a market in asylum facilitates the provision of asylum to those who need it. (shrink)

The concept of life plays a crucial role in the debate on synthetic biology. The first part of this chapter outlines the controversial debate on the status of the concept of life in current science and philosophy. Against this background, synthetic biology and the discourse on its scientific and societal consequences is revealed as an exception. Here, the concept of life is not only used as buzzword but also discussed theoretically and links the ethical aspects with the epistemological prerequisites and (...) the ontological consequences of synthetic biology. The second part examines this point of intersection and analyses some of the issues which are discussed in terms of the concept of life. The third part turns to the history of the concept of life. It offers an examination of scientific and philosophical discourses on life at the turn of the 20th century and suggests a surprising result: In the light of this history, synthetic biology leads to well-known debates, arguments, notions and questions. But it is concluded that the concept of life is too ambiguous and controversial to be useful for capturing the actual practice of synthetic biology. In the fourth part I argue that with regard to the ethical evaluation of synthetic biology, the ambiguity of the concept of life is not as problematic as sometimes held because other challenges are more important. The question whether the activity of synthetic biological systems should be conceived as life or not is primarily theoretical. (shrink)

The aim of this chapter is to clarify the meaning and the use of the concept of relativism in the context of National Socialism (NS). This chapter analyzes three aspects of the connection between relativism and NS: The first part examines the critical reproach that NS is a form of relativism. I analyze and criticize the common core of this widespread argument, which is developed in varying contexts, was held in different times, and is still shared by several authors. The (...) second part investigates the ideological debate among Nazi philosophers themselves concerning whether NS is indeed a form of relativism. I focus on the epistemological consequences of Nazi anthropology and analyze both its relativistic tendencies and the strategies used to reject relativism. In contrast to the received view, I argue that Nazi philosophers attempted to overcome both absolutism and relativism. The third part investigates the academic debate on relativism during NS, using the example of the prize question on relativism that was announced by the Prussian Academy of Science in 1936. By examining the academic approaches to the problem of relativism, I also address the question of how broader philosophical debates were related to the core of Nazi ideology. Academic philosophers took the self-understanding of Nazi philosophers seriously. They saw the shared aim of overcoming relativism as an opportunity to collaborate with NS. The brief conclusion summarizes the findings of the chapter. I conclude that, in the context of NS, critics, ideologists, and academics understand and use the concept of relativism in the same way.

In this paper we investigate with a case study from chemistry under what conditions a simulation can serve as a surrogate for an experiment. The case-study concerns a simulation of H2-formation in outer space. We find that in this case the simulation can act as a surrogate for an experiment, because there exists comprehensive theoretical background knowledge in form of quantum mechanics about the range of phenomena to which the investigated process belongs and because any particular modelling assumptions as can (...) be justified. If these requirements are met then direct empirical validation may even be dispensable. We conjecture that this is not the case in the absence of comprehensive theoretical background knowledge.

How to understand Brentano’s account of truth is a question of some controversy. A number of different views have been put forward as positions that Brentano held at some stage in his career. The received view has it that the early Brentano subscribed to a form of correspondence theory which he later rejected in favor of a definition of truth in terms of correct judging, where the correctness of a judgment is defined in terms of the notion of self-evidence (see (...) Kraus 1966, Szrednicki 1965, Stegmüller 1969, Kamitz 1983, Chrudzimski 2001). This fundamental shift in Brentano’s view is regarded as a change from an ontological to a “gnoseological”, i.e. epistemic, theory of truth (see Kastil 1934). Brentano’s mature view is sometimes said to resemble a neo-Kantian conception of truth or related views (see Kraus 1966, van der Schaar 1999, 2003), it has been compared with a coherence theory of truth (see Krantz 1990/91), and it is regarded as embracing a form of alethic anti-realism that places a substantial epistemic constraint on the concept of truth (see Künne 2003). More recently, Charles Parsons suggested that the early Brentano may also be regarded as a precursor of a deflationist theory of truth (see Parsons 2004). Following up on this proposal, the received view has been challenged by a new interpretation that ascribes to Brentano a deflationist position that he held throughout his career in combination with the view that truth pertains primarily to self-evident judgment (see Brandl forthcoming). Section 1 first summarizes the received view and then indicates two problems raised by this interpretation. Section 2 explains in which sense Brentano may have been a deflationist and how this interpretation avoids the problems of the received view. (shrink)

This chapter argues for a structural injustice approach to the governance of AI. Structural injustice has an analytical and an evaluative component. The analytical component consists of structural explanations that are well-known in the social sciences. The evaluative component is a theory of justice. Structural injustice is a powerful conceptual tool that allows researchers and practitioners to identify, articulate, and perhaps even anticipate, AI biases. The chapter begins with an example of racial bias in AI that arises from structural injustice. (...) The chapter then presents the concept of structural injustice as introduced by the philosopher Iris Marion Young. The chapter moreover argues that structural injustice is well suited as an approach to the governance of AI and compares this approach to alternative approaches that start from analyses of harms and benefits or from value statements. The chapter suggests that structural injustice provides methodological and normative foundations for the values and concerns of Diversity, Equity, and Inclusion. The chapter closes with an outlook onto the idea of “structure” and on responsibility. The idea of a structure is central to justice. An open theoretical research question is to what extent AI is itself part of the structure of society. Finally, the practice of responsibility is central to structural injustice. Even if they cannot be held responsible for the existence of structural injustice, every individual and every organization has some responsibility to address structural injustice going forward.

A central dispute in social ontology concerns the existence of group minds and actions. I argue that some authors in this dispute rely on rival views of existence without sufficiently acknowledging this divergence. I proceed in three steps in arguing for this claim. First, I define the phenomenon as an implicit higher-order disagreement by drawing on an analysis of verbal disputes. Second, I distinguish two theories of existence—the theory-commitments view and the truthmaker view—in both their eliminativist and their constructivist variants. (...) Third, I examine individual contributions to the dispute about the existence of group minds and actions to argue that these contributions have an implicit higher-order disagreement. This paper serves two purposes. First, it is a study to apply recent advances in meta-ontology. Second, it contributes to the debate on social ontology by illustrating how meta-ontology matters for social ontology. (shrink)

This paper develops a taxonomy of kinds of actions that can be seen in group agency, human–machine interactions, and virtual realities. These kinds of actions are special in that they are not embodied in the ordinary sense. I begin by analysing the notion of embodiment into three separate assumptions that together comprise what I call the Embodiment View. Although this view may find support in paradigmatic cases of agency, I suggest that each of its assumptions can be relaxed. With each (...) assumption that is given up, a different kind of disembodied action becomes available. The taxonomy gives a systematic overview and suggests that disembodied actions have the same theoretical relevance as the actions of any ordinarily embodied human. (shrink)

We show that any predicational theory of partial ground that extends a standard theory of syntax and that proves some commonly accepted principles for partial ground is inconsistent. We suggest a way to obtain a consistent predicational theory of ground.

We begin by considering two common ways of conceiving critical metaphysics. According to the first (and polemical) conception, critical metaphysics analyzes nothing more than the form of thought and thereby misses the proper point of metaphysics, namely to investigate the form of reality. According to the second (and affirmative) conception, critical metaphysics starts from the supposed insight that the form of reality cannot be other than the form of thought and is thus not required to analyze anything but that form. (...) We argue that the first conception is too weak while the second is too strong. Then we sketch an alternative conception of critical metaphysics, a conception we find expressed both in Kant’s B-Deduction and in the way Barry Stroud has recently investigated the possibility of metaphysics. According to such a conception, a properly critical metaphysics needs to proceed in two steps: first, it needs to analyze the most general and necessary form of any thought that is about an objective reality at all; second, it needs to investigate how that form of thought relates to the reality it purports to represent. But unlike Kant, Stroud remains sceptical regarding the possibility of a satisfying transition from thought to reality in metaphysics. We argue that this dissatisfaction can be traced back to a notion of objectivity and reality in terms of complete mind-independence. Then we sketch an alternative notion of objectivity and reality in terms of distinctness from subjects and acts of thinking, and argue that it is that notion that allows Kant, with his Transcendental Idealism, to make the transition required for any satisfying metaphysics, namely that from the form of thought to reality.

We explore a ‘Neo-Cartesian’ account of divine ultimacy that raises the concept of God to its ultimate level of abstraction so that we can do away with even the question of his existence. Our starting point is God’s relation to the logical and metaphysical order of reality and the views of Descartes and Leibniz on this topic. While Descartes held the seemingly bizarre view that the eternal truths are freely created by God, Leibniz stands for the mainstream view that the (...) eternal truths are grounded in God’s nature. We argue that the implausibility of Descartes’ doctrine stems mainly from the assumption that there is a non-epistemic notion of absolute necessity that constitutes the ultimate court of appeal for all modal questions and that this assumption is questionable. We also question the assumption that God’s ultimacy merely requires that all reality be grounded in God in the sense of mere explanation, so that it suffices if the necessary truths are grounded in God’s nature but not in God’s will. This will lead us to a reassessment of Descartes’ position. In the final and main part of the paper, we push Descartes’ doctrine of the creation of the eternal truths to its ‘logical’ conclusion with the aim of getting to a novel conception of ‘God.’. (shrink)
