Searle proposes an argument in order to prove the existence of universals and thereby solve the problem of universals: From every meaningful general term P(x) follows a tautology Vx[P(x) v -P(x)], which entails the existence of the corresponding universal P. To be convincing, this argument for existence must be valid, it must presume true premises and it must be free of any informal fallacy. First, the validity of the argument for existence in its non-modal interpretation will be proven with the (...) help of the formal deductive system F. Secondly, it will be shown that a self-contradictory tautology concept is employed, which renders the premises meaningless. Consequently, the inconsistency will be emended through redefinition and the argument's ensuing correctness will be demonstrated. Finally, it will be shown that the argument for existence presupposes the existence of universals in its premise and hence begs the question. (shrink)

The problem addressed in this paper is “the main epistemic problem concerning science”, viz. “the explication of how we compare and evaluate theories [...] in the light of the available evidence” (van Fraassen, BC, 1983, Theory comparison and relevant Evidence. In J. Earman (Ed.), Testing scientific theories (pp. 27–42). Minneapolis: University of Minnesota Press). Sections 1– 3 contain the general plausibility-informativeness theory of theory assessment. In a nutshell, the message is (1) that there are two values a theory should exhibit: (...) truth and informativeness—measured respectively by a truth indicator and a strength indicator; (2) that these two values are conflicting in the sense that the former is a decreasing and the latter an increasing function of the logical strength of the theory to be assessed; and (3) that in assessing a given theory by the available data one should weigh between these two conflicting aspects in such a way that any surplus in informativeness succeeds, if the shortfall in plausibility is small enough. Particular accounts of this general theory arise by inserting particular strength indicators and truth indicators. In Section 4 the theory is spelt out for the Bayesian paradigm of subjective probabilities. It is then compared to incremental Bayesian confirmation theory. Section 4 closes by asking whether it is likely to be lovely. Section 5 discusses a few problems of confirmation theory in the light of the present approach. In particular, it is briefly indicated how the present account gives rise to a new analysis of Hempel’s conditions of adequacy for any relation of confirmation (Hempel, CG, 1945, Studies in the logic of comfirmation. Mind, 54, 1–26, 97–121.), differing from the one Carnap gave in § 87 of his Logical foundations of probability (1962, Chicago: University of Chicago Press). Section 6 adresses the question of justification any theory of theory assessment has to face: why should one stick to theories given high assessment values rather than to any other theories? The answer given by the Bayesian version of the account presented in section 4 is that one should accept theories given high assessment values, because, in the medium run, theory assessment almost surely takes one to the most informative among all true theories when presented separating data. The concluding section 7 continues the comparison between the present account and incremental Bayesian confirmation theory. (shrink)

This article shows that a slight variation of the argument in Milne 1996 yields the log‐likelihood ratio l rather than the log‐ratio measure r as “the one true measure of confirmation. ” *Received December 2006; revised December 2007. †To contact the author, please write to: Formal Epistemology Research Group, Zukunftskolleg and Department of Philosophy, University of Konstanz, P.O.

This paper starts by indicating the analysis of Hempel's conditions of adequacy for any relation of confirmation (Hempel, 1945) as presented in Huber (submitted). There I argue contra Carnap (1962, Section 87) that Hempel felt the need for two concepts of confirmation: one aiming at plausible theories and another aiming at informative theories. However, he also realized that these two concepts are conflicting, and he gave up the concept of confirmation aiming at informative theories. The main part of the (...) paper consists in working out the claim that one can have Hempel's cake and eat it too - in the sense that there is a logic of theory assessment that takes into account both of the two conflicting aspects of plausibility and informativeness. According to the semantics of this logic, a is an acceptable theory for evidence β if and only if a is both sufficiently plausible given β and sufficiently informative about β. This is spelt out in terms of ranking functions (Spohn, 1988) and shown to represent the syntactically specified notion of an assessment relation. The paper then compares these acceptability relations to explanatory and confirmatory consequence relations (Flach, 2000) as well as to nonmonotonic consequence relations (Kraus et al., 1990). It concludes by relating the plausibility-informativeness approach to Carnap's positive relevance account, thereby shedding new light on Carnap's analysis as well as solving another problem of confirmation theory.

Degrees of belief are familiar to all of us. Our confidence in the truth of some propositions is higher than our confidence in the truth of other propositions. We are pretty confident that our computers will boot when we push their power button, but we are much more confident that the sun will rise tomorrow. Degrees of belief formally represent the strength with which we believe the truth of various propositions. The higher an agent’s degree of belief for a particular (...) proposition, the higher her confidence in the truth of that proposition. For instance, Sophia’s degree of belief that it will be sunny in Vienna tomorrow might be .52, whereas her degree of belief that the train will leave on time might be .23. The precise meaning of these statements depends, of course, on the underlying theory of degrees of belief. These theories offer a formal tool to measure degrees of belief, to investigate the relations between various degrees of belief in different propositions, and to normatively evaluate degrees of belief.

This paper shows that causation in the sense of Lewis is a special case of causation in the sense of Spohn.

Traditionally, the investigation of truth has been anchored in a priori reasoning. Cognitive science deviates from this tradition by adding empirical data on how people understand and use concepts. Building on psychophysics and machine learning methods, we introduce conceptual scaling, an approach to map people's understanding of abstract concepts. This approach, allows computing participant-specific conceptual maps from obtained ordinal comparison data, thereby quantifying perceived similarities among abstract concepts. Using this approach, we investigated individual's alignment with philosophical theories on truth and (...) the predictive capacity of conceptual maps. The obtained results indicated that, while people's understanding of truth is multifaceted and encapsulates notions of coherence and authenticity, alignment is best for the correspondence theory of truth. Furthermore, conceptual maps allowed predicting individual outcomes with an accuracy of roughly 70%. This research demonstrates that conceptual scaling offers accurate descriptions of individual's understanding of abstract concepts, behavioral predictions, and quantification of alignment with theoretical perspectives.

The paper provides an argument for the thesis that an agent’s degrees of disbelief should obey the ranking calculus. This Consistency Argument is based on the Consistency Theorem. The latter says that an agent’s belief set is and will always be consistent and deductively closed iff her degrees of entrenchment satisfy the ranking axioms and are updated according to the ranktheoretic update rules.

Philosophically, one of the most important questions in the enterprise termed confirmation theory is this: Why should one stick to well confirmed theories rather than to any other theories? This paper discusses the answers to this question one gets from absolute and incremental Bayesian confirmation theory. According to absolute confirmation, one should accept ''absolutely well confirmed'' theories, because absolute confirmation takes one to true theories. An examination of two popular measures of incremental confirmation suggests the view that one should stick (...) to incrementally well confirmed theories, because incremental confirmation takes one to (the most) informative (among all) true theories. However, incremental confirmation does not further this goal in general. I close by presenting a necessary and sufficient condition for revealing the confirmational structure in almost every world when presented separating data. (shrink)

The Spohnian paradigm of ranking functions is in many respects like an order-of-magnitude reverse of subjective probability theory. Unlike probabilities, however, ranking functions are only indirectly—via a pointwise ranking function on the underlying set of possibilities W —defined on a field of propositions A over W. This research note shows under which conditions ranking functions on a field of propositions A over W and rankings on a language L are induced by pointwise ranking functions on W and the set of (...) models for L, ModL, respectively.

Philosophers typically rely on intuitions when providing a semantics for counterfactual conditionals. However, intuitions regarding counterfactual conditionals are notoriously shaky. The aim of this paper is to provide a principled account of the semantics of counterfactual conditionals. This principled account is provided by what I dub the Royal Rule, a deterministic analogue of the Principal Principle relating chance and credence. The Royal Rule says that an ideal doxastic agent’s initial grade of disbelief in a proposition \(A\) , given that the (...) counterfactual distance in a given context to the closest \(A\) -worlds equals \(n\) , and no further information that is not admissible in this context, should equal \(n\) . Under the two assumptions that the presuppositions of a given context are admissible in this context, and that the theory of deterministic alethic or metaphysical modality is admissible in any context, it follows that the counterfactual distance distribution in a given context has the structure of a ranking function. The basic conditional logic V is shown to be sound and complete with respect to the resulting rank-theoretic semantics of counterfactuals. (shrink)

Belief revision theory studies how an ideal doxastic agent should revise her beliefs when she receives new information. In part I, I have first presented the AGM theory of belief revision. Then I have focused on the problem of iterated belief revisions. In part II, I will first present ranking theory (Spohn 1988). Then I will show how it solves the problem of iterated belief revisions. I will conclude by sketching two areas of future research.

Bayesianism is the position that scientific reasoning is probabilistic and that probabilities are adequately interpreted as an agent's actual subjective degrees of belief, measured by her betting behaviour. Confirmation is one important aspect of scientific reasoning. The thesis of this paper is the following: if scientific reasoning is at all probabilistic, the subjective interpretation has to be given up in order to get right confirmation—and thus scientific reasoning in general. The Bayesian approach to scientific reasoning Bayesian confirmation theory The example (...) The less reliable the source of information, the higher the degree of Bayesian confirmation Measure sensitivity A more general version of the problem of old evidence Conditioning on the entailment relation The counterfactual strategy Generalizing the counterfactual strategy The desired result, and a necessary and sufficient condition for it Actual degrees of belief The common knock-down feature, or ‘anything goes’ The problem of prior probabilities.

Recent accounts of actual causation are stated in terms of extended causal models. These extended causal models contain two elements representing two seemingly distinct modalities. The first element are structural equations which represent the or mechanisms of the model, just as ordinary causal models do. The second element are ranking functions which represent normality or typicality. The aim of this paper is to show that these two modalities can be unified. I do so by formulating two constraints under which extended (...) causal models with their two modalities can be subsumed under so called which contain just one modality. These two constraints will be formally precise versions of Lewissystem of weights or priorities” governing overall similarity between possible worlds. (shrink)

The problem adressed in this paper is “the main epistemic problem concerning science”, viz. “the explication of how we compare and evaluate theories [...] in the light of the available evidence” (van Fraassen 1983, 27).

The question I am addressing in this paper is the following: how is it possible to empirically test, or confirm, counterfactuals? After motivating this question in Section 1, I will look at two approaches to counterfactuals, and at how counterfactuals can be empirically tested, or confirmed, if at all, on these accounts in Section 2. I will then digress into the philosophy of probability in Section 3. The reason for this digression is that I want to use the way observable (...) absolute and relative frequencies, two empirical notions, are used to empirically test, or confirm, hypotheses about objective chances, a metaphysical notion, as a role-model. Specifically, I want to use this probabilistic account of the testing of chance hypotheses as a role-model for the account of the testing of counterfactuals, another metaphysical notion, that I will present in Sections 4 to 8. I will conclude by comparing my proposal to one non-probabilistic and one probabilistic alternative in Section 9. (shrink)

I raise an example that suggests that Andrea Kern’s Knowledge View of Perception should concede that a mere perceptual experience can be a potentiality for one to know something on its basis. I argue that the Knowledge View can accommodate this suggestion by distinguishing between two kinds of defective exercises of a capacity for perceptual knowledge, namely failed and incomplete exercises. I explain that, rather than collapsing the Knowledge View into the contrary Two-Capacity View, my suggestion further articulates the definitive (...) insight of the Knowledge View, namely that perceptual experience, on the basis of which one knows, issues from the same capacity as the knowledge enabled by it.

This paper presents a new analysis of C.G. Hempel’s conditions of adequacy for any relation of confirmation [Hempel C. G. (1945). Aspects of scientific explanation and other essays in the philosophy of science. New York: The Free Press, pp. 3–51.], differing from the one Carnap gave in §87 of his [1962. Logical foundations of probability (2nd ed.). Chicago: University of Chicago Press.]. Hempel, it is argued, felt the need for two concepts of confirmation: one aiming at true hypotheses and another (...) aiming at informative hypotheses. However, he also realized that these two concepts are conflicting, and he gave up the concept of confirmation aiming at informative hypotheses. I then show that one can have Hempel’s cake and eat it too. There is a logic that takes into account both of these two conflicting aspects. According to this logic, a sentence H is an acceptable hypothesis for evidence E if and only if H is both sufficiently plausible given E and sufficiently informative about E. Finally, the logic sheds new light on Carnap’s analysis. (shrink)

This paper discusses an almost sixty year old problem in the philosophy of science -- that of a logic of confirmation. We present a new analysis of Carl G. Hempel's conditions of adequacy (Hempel 1945), differing from the one Carnap gave in §87 of his Logical Foundations of Probability (1962). Hempel, it is argued, felt the need for two concepts of confirmation: one aiming at true theories and another aiming at informative theories. However, he also realized that these two concepts (...) are conflicting, and he gave up the concept of confirmation aiming at informative theories. We then show that one can have Hempel's cake and eat it, too: There is a (rank-theoretic and genuinely nonmonotonic) logic of confirmation -- or rather, theory assessment -- that takes into account both of these two conflicting aspects. According to this logic, a statement H is an acceptable theory for the data E if and only if H is both sufficiently plausible given E and sufficiently informative about E. Finally, the logic sheds new light on Carnap's analysis (and solves another problem of confirmation theory). (shrink)

Many interpretations of Kant’s first Critique fail to appreciate the revolutionary nature of his account of knowledge and its implications for skepticism, givenness and mind-independence, because they read Kant as holding a compositional account of knowledge. I contend that the reason for this is that this account is both naturally appealing in its own right, and fits an influential reading of Kant’s Transcendental Deduction. On this reading, the Deduction aims to respond to a skeptical worry which issues from the empiricist (...) version of epistemic compositionalism and which questions the intelligibility of the claim to knowledge of our judgements. Against this, I argue that what Kant’s Deduction actually aims to address is a radicalization of this epistemic worry, which instead questions the intelligibility of the objective purport of our judgements. I contend that the compositional account is unable to respond to this more radical worry, thereby putting it into question both as a reading of Kant, and as an account of knowledge generally. To corroborate this, I provide a reading of the Deduction that overcomes epistemic compositionalism by thinking through its shortcomings in order to arrive at a more adequate successor account: the hylomorphic account of knowledge, which, I contend, is able to dissolve both the more radical and the epistemic worry. I suggest that this implies generally that the epistemic worry issuing from the compositional account is not self-contained, but must give way to Kant’s more radical worry, which I argue can only be addressed within the underappreciated framework of epistemic hylomorphism.

The thesis of this paper is that we can justify induction deductively relative to one end, and deduction inductively relative to a different end. I will begin by presenting a contemporary variant of Hume ’s argument for the thesis that we cannot justify the principle of induction. Then I will criticize the responses the resulting problem of induction has received by Carnap and Goodman, as well as praise Reichenbach ’s approach. Some of these authors compare induction to deduction. Haack compares (...) deduction to induction, and I will critically discuss her argument for the thesis that we cannot justify the principles of deduction next. In concluding I will defend the thesis that we can justify induction deductively relative to one end, and deduction inductively relative to a different end, and that we can do so in a non-circular way. Along the way I will show how we can understand deductive and inductive logic as normative theories, and I will briefly sketch an argument to the effect that there are only hypothetical, but no categorical imperatives.

Can sensibility, as our capacity to be sensibly presented with objects, be understood independently of the understanding, as the capacity to form judgments about those objects? It is a truism that for judgments to be empirical knowledge they must agree with what sensibility presents. Moreover, it is a familiar thought that objectivity involves absolute independence from intellectual acts. The author argues that together these thoughts motivate a common reading of Kant on which operations of sensibility are conceived as intelligible independently (...) of acts of the understanding, so that their supposed objectivity can validate judgments as empirical knowledge. He contends that there are two reasons why this epistemic compositionalism is implausible both as a reading of Kant and in itself. First, read compositionally, Kant’s Transcendental Deduction is unable to fulfill its stated aim of showing that the categories are objectively valid, that is, exemplified by the objects that sensibility presents. Second, Kant sees that sensibility by itself cannot be understood to even purport to present objects, thus undermining the very intelligibility of compositionalism. The author argues that, given these challenges, Kant’s Deduction develops an alternative account, on which operations of sensibility and acts of the understanding can be understood only together. He contends that this epistemic hylomorphism transforms the familiar thought underlying compositionalism: objectivity simultaneously involves formal agreement with intellectual acts in general and material independence from any specific such act. He thus shows how Kant reconceives our conception of objectivity by overcoming compositionalism in favor of hylomorphism. (shrink)

Crupi et al. propose a generalization of Bayesian confirmation theory that they claim to adequately deal with confirmation by uncertain evidence. Consider a series of points of time t0, . . . , ti, . . . , tn such that the agent’s subjective probability for an atomic proposition E changes from Pr0 at t0 to . . . to Pri at ti to . . . to Prn at tn. It is understood that the agent’s subjective probabilities change for (...) E and no logically stronger proposition, and that the agent updates her subjective probabilities by Jeffrey conditionalization. For this specific scenario the authors propose to take the difference between Pr0 and Pri as the degree to which E confirms H for the agent at time ti , C0,i. This proposal is claimed to be adequate, because. (shrink)

Weisberg introduces a phenomenon he terms perceptual undermining. He argues that it poses a problem for Jeffrey conditionalization, and Bayesian epistemology in general. This is Weisberg’s paradox. Weisberg argues that perceptual undermining also poses a problem for ranking theory and for Dempster-Shafer theory. In this note I argue that perceptual undermining does not pose a problem for any of these theories: for true conditionalizers Weisberg’s paradox is a false alarm.

Any theory of confirmation must answer the following question: what is the purpose of its conception of confirmation for scientific inquiry? In this article, we argue that no Bayesian conception of confirmation can be used for its primary intended purpose, which we take to be making a claim about how worthy of belief various hypotheses are. Then we consider a different use to which Bayesian confirmation might be put, namely, determining the epistemic value of experimental outcomes, and thus to decide (...) which experiments to carry out. Interestingly, Bayesian confirmation theorists rule out that confirmation be used for this purpose. We conclude that Bayesian confirmation is a means with no end. 1 Introduction2 Bayesian Confirmation Theory3 Bayesian Confirmation and Belief4 Confirmation and the Value of Experiments5 Conclusion.

This dissertation articulates our human capacity to judge as a capacity for knowledge, specifically for empirical knowledge, and for knowledge of itself as such. I interpret and draw on the account of such knowledge presented by Kant’s Critique of Pure Reason, situate this account historically, and relate it to relevant contemporary debates. The first chapter motivates my project by assessing the insights and shortcomings of Cartesian epistemology. I argue that while Descartes draws on the essential self-consciousness of judgement to show (...) that the cogito is knowledge, he fails, by his own standards, to secure this status for any judgement beyond the cogito. I conclude that self-consciousness alone is empty, but that, since we can judge beyond the cogito, judgement can be given content from elsewhere. The next chapter evaluates the empiricist doctrine that operations of the senses by themselves give content to judgement and can vindicate it as empirical knowledge. I contend that Kant deepens Hume’s finding, that empiricism fails to enable us to explain empirical knowledge, into the more radical insight that empiricism fails to enable us to understand the senses as providing any content. I conclude that the senses alone are blind and that our account of empirical knowledge must privilege neither sensory givenness nor intellectual self-consciousness. The third chapter contrasts two readings of Kant on the cooperation between sensibility and understanding in empirical knowledge. I argue, against many Kantians, that the Transcendental Deduction shows that instead of understanding this cooperation compositionally – so that operations of sensibility are intelligible independently of acts of the understanding – we must conceive of it hylomorphically – so that the operations of sensibility and understanding constitute the mutually dependent matter and form of empirical knowing respectively. The final chapter substantiates this hylomorphism by explicating the form of knowledge as synthesis. Following Kant, I argue that inference is a species of synthesis and provide a synthetic explanation of inference. The resulting account simultaneously illustrates synthesis, addresses a prominent contemporary problem regarding the nature of inference, and explains how our capacity to know provides not just isolated glimpses of empirical reality, but a unified conception of it.

Ranking functions have been introduced under the name of ordinal conditional functions in Spohn (1988; 1990). They are representations of epistemic states and their dynamics. The most comprehensive and up to date presentation is Spohn (manuscript).

In this thesis I try to evaluate the risks and potentials of modern and archaic myths for human existence in a holistical approach. After Adorno's and Horkheimer's critique that enlightment would still be mythical the positive aspects of myth and ancient religion were - with a few exceptions (i.g. Blumenberg, Eliade) - mostly neglected: In the analysis of Critical Theory myth only serves power, its misuse in fashist and capitalistic societies is inevitable; therefore any hint of mythological structures needs to (...) be destroyed. Even so, myth as one of the first tools of sensemaking had made sure that humanity clings to life through entire history. In the words of Baudrillard and Blumenberg, mythical (and, further on, religious and rationalistic) icons preserves their followers to get in touch with an overwhelming reality. The mythical tills the world as an factual entity and, in the cultural aspect, as an entity shapeable by "our" collective power. With the evidence given of increasing difficulties for finding "Bedeutsamkeit" (Blumenberg) in individual life, the bivalency of myth illustrates a promising oppurtunity for individual and existential sensemaking.

Max Scheler's concept of the “becoming god” and its implication of mankind as his “ally” has been a long-time target of relentless criticism. The strongest objections were made mainly against the tendency of overestimating the human share in the affairs of being, culminating in the groundless self-idealization of mankind. Put aside these fierce reactions, Scheler's notion of “being in progress” however seems to be accurate overall: If the spheres of being can be described as matter, life and spirit, and the (...) balance between all of them is what defines being as a whole, then currently being is indeed not fully existent yet and therefore still has to be unfolded. Strangely enough, in Scheler's view it is mainly the lower spheres of being, more precisely the urge of life (“Lebensdrang”) that holds the power of unfolding all other – without it, pure spirit would have been absolutely powerless. In this sense, the life-related power of mankind holds the potential to help evolving the higher spheres of being, since natural evolution (at least in terms of experience) has mostly come to an end for the contemporary human race. Henceforth, helping spirit unfold is a matter of intentional decision, since it doesn't unfold by default anymore. When assuming Scheler's term of eros as the mediator between life and spirit, mankind analogously seems to become the becoming god's eros. In this article, I explore what the implications of this conclusion might be. (shrink)

Since Jürgen Habermas' speech for the Peace Price of the German Book Trade in October 2001, secular reason – personified by one of its main protagonists – has been able to debate with religion anew. For the purpose of an unbiased encounter between philosophy and religion, Habermas introduced the term “postsecular” back then in order to emphasize that this dialogue was inevitably necessary, all the more in the face of religiously motivated terrorism. Nonetheless, this willingness to debate was accompanied by (...) the conviction that secular reason itself, as a matter of fact, would be “ideologically neutral”. However, taking the necessity of accomplishing the confrontation with “world” (Weltbewältigung) seriously, the reflection on world view as a whole unveils its implied tasks of granting metaphysical and existential certainty (metaphysische Sicherheit), therefore resulting in the statement that there cannot be a neutral world view at all. Only dialogue as exchange of beliefs generates the general framework within which the discursive issues of world views are separated from their existential aspects, thus enabling a reasonably conducted debate without endangering the existential certainty of its participants. As a consequence, the neutrality of world views exclusively rests in dialogue and is no unique feature of secular reason at all. Eventually, this leads to the reconsideration of the conditions that must be given for an argument to be called “rational”. The article tries to point out that an argument in political contexts, whether given by a religious or a secular person, should only be acknowledged rational if it takes at least all living people – regardless of their group affiliations – into account.

In his 1968 poetry collection „Fadensonnen“, Paul Celan offers a hermetic blend of existentialism and mysticism, which is unusual in two respects. Firstly, the European philosophy of existence, especially with its proponents Jean-Paul Sartre, Albert Camus and Martin Heidegger, had gone to great lengths to criticize and delegitimize the Abrahametic religions, for the concept of god seemed to be an obstacle to humanity in pursuit of its own humanization. Secondly, in the aftermath of the holocaust, the idea of man wanting (...) to merge with a god that had not prevented this cruelty from happening had lost much of its plausibility. Despite these two objections, Celan's poems address the struggle of togetherness in a world that negates the mere possibility of otherness, trying to salvage the unique identity and dignity of the other. With this in mind, the modus operandi of his poems is that of a butcher: Whatever has previously been alive – before the Shoah – now has to be stripped bare of its layers of individual and collective history, has to become less than body and flesh. In this way, the poems' inherent pain and misery transform the reader into a nobody, for only a nobody has got the prerequisites to encounter other people unbiasedly in their unique wholeness. Within this space of encounter, only the reminiscence of body and sexuality exists, commemorating the other, so that radical corporeality seems to be the prerequisite for togetherness. In this ahistorical sphere there is no room for a god that permitted the holocaust, redefining mysticism as the connection between men instead of one between man and god. Celan's poems act as a catalyst, for they exclude god from the spheres of man, making poetry a memorial site to the dead and the ones living in pain. This way, the poems are trying to save Eros (in the sense of creaturely love) from being mutilated by the crimes of European history while at the same time aiming at rehabilitating mankind in a post-holocaust world.

Does a nihilist who kills himself betray his own beliefs? An unreflected answer would probably turn out positive, because a nihilist may be defined as a person who embraces all aspects of life and pain itself. But someone who escapes his sorrowful existence by committing suicide seems not to accept his own human condition and therefore cannot die as a nihilist. If this argumentation is right, human life would not be possible outside cultural contexts, for the particularity of nihilism is (...) its large distance to and independence of culture and collectivity. In his autobiographical work "Arbeit und Struktur" Wolfgang Herrndorf portrays his three and a half years of living with brain cancer. At the same time he shows us how his originally humanistic nihilism turns into a more pessimistic one while coping with his disease. Herrndorf, in a manner of speaking, writes his own "myth to live" without being able to rely on the shelter of culture, without a "myth of collectivity". In the face of this, we must assume Herrndorf's ideological transformation from a cooperative nihilism to a pessimistic nihilism, which justifies his own death, was his sole opportunity to mentally survive the three and a half years of pain and dissolution. From this perspective, the example of Wolfgang Herrndorf and his "Arbeit und Struktur" would reveal mankind's absolute dependency on metaphysical significance and its need for individual myths to live. Despite regarding himself as a modern, secular and rationalistic human being, Herrndorf cannot overcome the necessity of the iconological translation of "reality to world". Therefore, the intent of this master's thesis is to show that all living human beings are captives of icons and their metaphysical representation, and that the endless effort of translating whole reality into a single myth to live is part of our conditio humana.

Logic is the study of the quality of arguments. An argument consists of a set of premises and a conclusion. The quality of an argument depends on at least two factors: the truth of the premises, and the strength with which the premises confirm the conclusion. The truth of the premises is a contingent factor that depends on the state of the world. The strength with which the premises confirm the conclusion is supposed to be independent of the state of (...) the world. Logic is only concerned with this second, logical factor of the quality of arguments. (shrink)

There are many psychic mechanisms by which people engage with their selves. We argue that an important yet hitherto neglected one is self-appraisal via meta-emotions. We discuss the intentional structure of meta-emotions and explore the phenomenology of a variety of examples. We then present a pilot study providing preliminary evidence that some facial displays may indicate the presence of meta-emotions. We conclude by arguing that meta-emotions have an important role to play in higher-order theories of psychic harmony.

It was the emphasis of Søren Kierkegaard's railing against 19th-century Danish Christianity in all its ruthlessness that eventually led him to utterly reject and actively fight the majority of the contemporary as well as important aspects of the historical discourse on Christianity. One of the aspects that Kierkegaard distanced himself from sharply consists in the long tradition of Christian mysticism. Nevertheless his concept of the “knight of faith” reveals several deliberations that appear to be close to mystical Christian conceptions (e.g. (...) the meaning of suffering or despair for the leap of faith, an increasing awareness of sin and guilt as well as the conditions for the knight of faith's secular ministry). Thus, Kierkegaard's critique of mysticism suggests his misunderstanding of the mystical perspective's implications. This essay tries to solve said misunderstanding between Kierkegaard and christian tradition by interrelating the process of becoming a knight of faith with the mystical responsibility before the divine and the ethical responsibility before all of humanity.

We argue that a semantics for counterfactual conditionals in terms of comparative overall similarity faces a formal limitation due to Arrow’s impossibility theorem from social choice theory. According to Lewis’s account, the truth-conditions for counterfactual conditionals are given in terms of the comparative overall similarity between possible worlds, which is in turn determined by various aspects of similarity between possible worlds. We argue that a function from aspects of similarity to overall similarity should satisfy certain plausible constraints while Arrow’s impossibility (...) theorem rules out that such a function satisfies all the constraints simultaneously. We argue that a way out of this impasse is to represent aspectual similarity in terms of ranking functions instead of representing it in a purely ordinal fashion. Further, we argue against the claim that the determination of overall similarity by aspects of similarity faces a difficulty in addition to the Arrovian limitation, namely the incommensurability of different aspects of similarity. The phenomena that have been cited as evidence for such incommensurability are best explained by ordinary vagueness. (shrink)

In his recently published posthumous works "Prefiguration" and "The Rigorism of Truth" Hans Blumenberg surprisingly steps into the area of political history that he had left widely unconsidered in "Work on Myth". While "Prefiguration" tackles the “demonic” aspects of Napoleon and Hitler that Blumenberg tries to dismantle and bring into derision, in "Rigorism of Truth" he attacks Hannah Arendt's phrase of the Banality of Evil in relation to the Jerusalem trial against Adolf Eichmann in 1961. In this latter issue Blumenberg (...) defends the demonic he sees culminated in the form of Eichmann to assert what he calls the “mythical dimension“ in the Israeli process of nation-building. To him, Eichmann represents a prototypical demon incarnate that must be slaughtered by the heroic character seen in young state Israel. This obviously turns Blumenberg's criticism of Napoleon and Hitler into an affirmation of political myths that, on the face of it, appears to be a contradiction in terms. The essay focuses on this theoretical tension and tries to point out that significance (“Bedeutsamkeit”) is not only a necessity for individual self-assertion (“Selbstbehauptung”) but also a category of communality that must be handled with care.

Ist die Begrenzung von staatlichen Ausgaben und Haushaltsdefiziten wirklich im Sinne der Generationengerechtigkeit? Wer begreift, wie unser Geldsystem tatsächlich funktioniert, muss diese Frage eindeutig und vehement verneinen.

Historical and cultural approaches to climate generally consider climate to be a stabilising concept between weather and culture. Different historical and cultural concepts of climate signify different ways of learning to live with the weather. However, anthropogenic climate change evidences the limit of this approach: instead of stabilising, climates ephemeralise together with the ways we have come to adapt to them. Changing climates require a concept of climate that captures how climates are experienced both as stable and ephemeral. To create (...) such a concept, I engage in an exercise of counterfactual etymology, reconstructing the concept of climate that might have emerged from the Ancient Greek term hora as opposed to klima. Central to my re-creation of phenomenological climate are Plato's myths, through which I highlight the methodological kinship between myth and phenomenology. Drawing on a later dialogue, Philebus, I provide an ontological account of climates as both stable and ephemeral. I conclude by situating my approach to climate and its changes in recent work on the relationship between weather and climate, arguing for the necessity of phenomenological climate in order to make sense of what changes with climate change. My turn to Ancient Greek philosophy and its application to the phenomenology of climate and its changes sounds out a novel approach to research in historical geography. (shrink)

Since at least Luhmann, contingency – whose conceivability must be reduced to a great extent by means of “reduction of complexity“ in order to assure stability of social and psychological systems – has been an important topos of sociological theory. What is a genuinely philosophical approach of the past decades, on the other hand, is the idea of its conceivability as being conducive for the purpose of individual autonomy. If both assumptions held equally true, collectivity and mature individuality would effectively (...) contradict each other: Mere affiliation with a collective would be the most efficient way to flee from the existential threat that is contingency, while the questioning of affiliation would require the capacity of enduring said threat. However, an individual that is thoroughly shielded from specific experiences of contingency will have little reason to break loose from its original collective environment and to expose itself to the burden of contingency. Consequently, autonomy would solely – if ever – be possible outside of any collective context and the idea of reasonably founded social liability coined at times of the Enlightenment would ultimately become obsolete. Alasdair MacIntyre and Hans Blumenberg rank among the authors who have dealt with this dilemma in their own specific ways. What makes both of them relevant to the search for a possible solution is the emphasis with which they have included existential as well as cultural contingency in the topos of human identity. The consideration of narrative categories plays an important part at this point: For it is MacIntyre´s conception of the human being as a “story-telling animal“ – surely Blumenberg would concur with this wording – that allows us to particularly understand the myth-building, rhetoric engagement with the world´s unreliability as a crucial structural factor of man´s conduct of life. Contingency always had to be “digested“ in some way or other, either had to be veiled and disowned or made accessible and bearable in order to guarantee man´s metaphysical potentiality – which both MacIntyre and Blumenberg do by molding the unpredictable and the perilous into collective and singular narrations. It is obvious that the collective narratives are superordinate to the individual ones: First and foremost, we are always members of a specific cultural environment who can only hope to obtain an autonomous identity by means of distancing ourselves from this environment to a certain extent. At the same time, as mentioned before, this cultural context serves as the best possible protection against existential contingency; in this regard, MacIntyre and Blumenberg think of cultural reduction of contingency as necessary but yet obstructive to the formation of a resilient individual and autonomous identity. Setting out from here, this essay discusses the extent to which the individual recognition of cultural and existential contingency plays a part in MacIntyre´s and Blumenberg´s concept of a responsible yet socially agreeable identity. It will become obvious that a close connection can be drawn between the affirmation of one´s own cultural contingency and the one of one´s potential suffering in “limit situations” (Karl Jaspers): Human identity could only live up to the task of dealing with existential contingency appropriately by equally admitting its own cultural contingency – and thus the cultural contingency of every other person as well. The affirmation of cultural contingencies and differences would establish a new “genre-specific” reliability that could potentially dismantle the paradigm of (post)modern tentativeness criticized by MacIntyre and Blumenberg and that could return visions of an open and humane future to contemporary societies.

Soda taxes are controversial. While proponents point to their potential health benefits and the public projects that could be funded with their revenue, critics argue that they are paternalistic and regressive. In this paper, we explore the prospects for designing a just soda tax, one that appropriately balances the often-competing ethical considerations of promoting social welfare, respecting people’s autonomy and ensuring distributive fairness. We argue that policymakers have several paths forward for designing a just soda tax, but that the considerations (...) relevant to ethical policy design are more complicated than is sometimes acknowledged.

This paper summarizes (in German) recent tendencies in the philosophy of the life sciences.

This is a pdf of a Mathematica calculation that supplements the paper "Presentist Fragmentalism and Quantum Mechanics" forthcoming in Foundations of Physics. In that paper the Born rule (or at least a progenitor) is derived from experimental conditions on the mutual observations of two fragments. In this pdf the experimental conditions are applied to Hilbert space dimensions 3, 4, and 5. It turns out each of these have a 1-dimensional solution space which, it is hoped, can be interpretated as the (...) phase. (shrink)
