This article suggests a ‘best alternative' justification of induction (in the sense of Reichenbach) which is based on meta-induction . The meta-inductivist applies the principle of induction to all competing prediction methods which are accessible to her. It is demonstrated, and illustrated by computer simulations, that there exist meta-inductivistic prediction strategies whose success is approximately optimal among all accessible prediction methods in arbitrary possible worlds, and which dominate the success of every noninductive prediction strategy. The proposed justification of meta-induction is (...) mathematically analytical. It implies, however, an a posteriori justification of object-induction based on the experiences in our world. *Received November 2005; revised March 2008. †To contact the author, please write to: Department of Philosophy, University of Duesseldorf, Universitaetsstrasse 1, Geb. 23.21, Duesseldorf, Germany D-40225; e-mail: gerhard[email protected].

This paper supplements an earlier one (Wassermann 1978b). Its views aim to reinforce those of Lewontin and other prominent evolutionists, but differ significantly from the opinions of some philosophers of science, notably Popper (1957) and Olding (1978). A basic distinction is made between 'laws' and 'theories of mechanisms'. The 'Theory of Evolution' is not characterized by laws, but is viewed here as a hypertheory which explains classifiable evolutionary phenomena in terms of subordinate classifiable theories of 'evolution-specific mechanisms' (ESMs), each of (...) which could apply to a host of species. Adaptations could result from ESMs that are rooted in molecular complementarities. The status of optimization theories that aim to predict best adapted states of organisms or populations is also discussed. (shrink)

One of the most discussed issues in psychology—presently and in the past—is how to define and measure the extent to which human cognition is rational. The rationality of human cognition is often evaluated in terms of normative standards based on a priori intuitions. Yet this approach has been challenged by two recent developments in psychology that we review in this article: ecological rationality and descriptivism. Going beyond these contributions, we consider it a good moment for psychologists and philosophers to join (...) forces and work toward a new foundation for the definition of rational cognition. We take a first step in this direction by proposing that the rationality of both cognitive and normative systems can be measured in terms of their cognitive success. Cognitive success can be defined and gauged in terms of two factors: ecological validity (the system's validity in conditions in which it is applicable) and the system's applicability (the scope of conditions under which it can be applied). As we show, prominent systems of reasoning—deductive reasoning, Bayesian reasoning, uncertain conditionals, and prediction and choice—perform rather differently on these two factors. Furthermore, we demonstrate that conceptualizing rationality according to its cognitive success offers a new perspective on the time-honored relationship between the descriptive (“is”) and the normative (“ought”) in psychology and philosophy.

This paper elaborates on the following correspondence theorem (which has been defended and formally proved elsewhere): if theory T has been empirically successful in a domain of applications A, but was superseded later on by a different theory T* which was likewise successful in A, then under natural conditions T contains theoretical expressions which were responsible for T’s success and correspond (in A) to certain theoretical expressions of T*. I illustrate this theorem at hand of the phlogiston versus oxygen theories (...) of combustion, and the classical versus relativistic theories of mass. The ontological consequences of the theorem are worked out in terms of the indirect reference and partial truth. The final section explains how the correspondence theorem may justify a weak version of scientific realism without presupposing the no-miracles argument. (shrink)

In the first part of my paper I discuss eight arguments in favour of the theory-dependence of observation: realistic content, guidance function of theories, perception as cognitive construction, expectation-dependence of perception, theory-dependence of scientific data, continuity between observational and theoretical concepts, language-dependence, and meaning holism. I argue that although these arguments make correct points, they do not exclude the existence of observations that are weakly theory-neutral in the sense that they don’t depend on acquired background knowledge. In the second part (...) I suggest an experimental method, the method of ostensive learning experiments, by which the degree of theory- and language-independence of a concept can be tested. (shrink)

White (2015) proposes an a priori justification of the reliability of inductive prediction methods based on his thesis of induction-friendliness. It asserts that there are by far more induction-friendly event sequences than induction-unfriendly event sequences. In this paper I contrast White's thesis with the famous no free lunch (NFL) theorem. I explain two versions of this theorem, the strong NFL theorem applying to binary and the weak NFL theorem applying to real-valued predictions. I show that both versions refute the thesis (...) of induction-friendliness. In the conclusion I argue that an a priori justification of the reliability of induction based on a uniform probability distribution over possible event sequences is impossible. In the outlook I consider two alternative approaches: (i) justification externalism and (ii) optimality justifications. (shrink)

One persistent puzzle in the life sciences is the asymmetric lipid composition of the cellular plasma membrane: while the exoplasmic leaflet is enriched in lipids carrying predominantly saturated fatty acids, the cytoplasmic leaflet hosts preferentially lipids with (poly‐)unsaturated fatty acids. Given the high energy requirements necessary for cells to maintain this asymmetry, the question naturally arises regarding its inherent benefits. In this paper, we propose asymmetry to represent a potential solution for harmonizing two conflicting requirements for the plasma membrane: first, (...) the need to build a barrier for the uncontrolled influx or efflux of substances; and second, the need to form a fluid and dynamic two‐dimensional substrate for signaling processes. We hence view here the plasma membrane as a composite material, where the exoplasmic leaflet is mainly responsible for the functional integrity of the barrier and the cytoplasmic leaflet for fluidity. We reinforce the validity of the proposed mechanism by presenting quantitative data from the literature, along with multiple examples that bolster our model. (shrink)

Although I agree with Elqayam & Evans' (E&E's) criticisms of is-ought and ought-is fallacies, I criticize their rejection of normativism on two grounds: (1) Contrary to E&E's assumption, not every normative system of reasoning consists of formal rules. (2) E&E assume that norms of reasoning are grounded on intuition or authority, whereas in contemporary epistemology they have to be justified, primarily by their truth-conduciveness.

Suppose two people are about to drown. We are in a position to save only one, so the other will have to die. One of the two has just culpably killed an innocent person, but has no intention of killing anybody else and there is no reason to expect that he will. Everything else being equal, should we give them an equal chance of being saved by flipping a coin? In this paper I argue that we should not. I argue (...) that the implications of a person's moral culpability for (recent or prospective) harm to a particular victim should transfer to other conflict situations in which the wrongdoer might find him or herself. This requires establishing the extent to which a person's contributing to harming another person — and his moral culpability for that harm — impinges on our decision making in situations where it is possible only to assist either the wrongdoer or some other person that is not his victim.

This chapter offers a close reading of a passage from the literary and philosophical work Minima Moralia that enacts Theodor W. Adorno's radical concept of nonpropositional truth content in philosophical aesthetics after Auschwitz. Readers of Adorno's texts, especially those devoted to philosophical aesthetics, can hardly fail to be struck by their chiastic structure. The aesthetic theory that Adorno develops constitutes not only a theory of the aesthetic but also a theory that is itself aesthetic, hence a theory of literature that (...) exhibits qualities associated with literary texts, and a theory of music that harbors within itself traces of musical composition. The rhetorically self-conscious tropes of his posthumous Aesthetic Theory, the stylized literary studies of his Notes to Literature, his musically inflected meditations on musicological questions from Ludwig van Beethoven to Arnold Schönberg, and so many of his other texts perform this provocative inversion in a variety of registers and conceptual modulations.

Wer hat sich nicht schon gefragt, was es mit unseren moralischen Überzeugungen auf sich hat: Spiegeln diese die Wahrheit in Sachen Moral wieder? Gibt es eine solche Wahrheit überhaupt? Oder sind moralische Überzeugungen eher das Produkt unserer Interessen und Neigungen, Ausdruck unserer Wünsche oder Mittel der Machtausübung, das bloße Ergebnis unserer Erziehung, unseres sozialen Umfelds oder gar eine List der Evolution? Ist es eine Illusion, wenn man glaubt, echte moralische Erkenntnisse gewinnen zu können? Kurzum: Kann die Moral Objektivität beanspruchen? Die (...) vorliegende Arbeit versucht, eine Antwort auf diese zentrale Frage der Metaethik zu geben. Dazu wird zunächst gezeigt, dass uns der Status der Moral ein Rätsel ist, weil wir dazu neigen, drei Thesen für wahr zu halten, die nicht zugleich wahr sein können. Die drei prinzipiell möglichen Strategien zur Auflösung dieses Trilemmas geraten jedoch in Schwierigkeiten, weil es bisher nicht gelungen ist, ein passendes Vergleichsobjekt für die Moral zu finden. In dieser Arbeit wird dafür argumentiert, dass die Moral in genau der gleichen Weise wie die Wissenschaft Objektivität beanspruchen kann. (shrink)

Two major works in recent evolutionary biology have in different ways touched upon the issue of cultural replicators in language, namely Dawkins’ Selfish Gene and Maynard Smith and Szathmáry’s Major Transitions in Evolution. In the latter, the emergence of language is referred to as the last major transition in evolution, a claim we argue to be derived from a crucial property of language, called Duality of Patterning. Prima facie, this property makes natural language look like a structural equivalent to DNA, (...) and its peer in terms of expressive power. We will argue that, if one takes seriously Maynard Smith and Szathmáry’s outlook and examines what has been proposed as linguistic replicators, amongst others phonemes and words, the analogy meme-gene becomes problematic. A key issue is the fact that genes and memes are assumed to carry and transmit information, while what has been described as the best candidate for replicatorhood in language, i.e. the phoneme, does by definition not carry meaning. We will argue that semiotic systems with Duality of Pattering force us to reconsider either the analogy between replicators in the biological and the cultural domain, or what it is to be a replicator in linguistics.

In sec. 1.1 I emphasize the meliorative purpose of epistemology, and I characterize Goldman's epistemology as reliabilistic, cognitive, social, and meliorative. In sec. 1.2 I point out that Goldman's weak notion of knowledge is in conflict with our ordinary usage of 'knowledge'. In sec. 2 I argue for an externalist-internalist hybrid conception of justification which adds reliability-indicators to externalist knowledge. Reliability-indicators produce a veritistic surplus value for the social spread of knowledge. In sec. 3 I analyze some particular meliorative rules (...) which have been proposed by Goldman. I prove that obedience to the rule of maximally specific evidence increases expected veritistic value (sec. 3.1), and I argue that rule-circular arguments are epistemically worthless (sec. 3.2). In the final sec. 3.3 I report a non-circular justification of meta-induction which has been developed elsewhere. (shrink)

Two conditions guiding permissible use of force in self-defence are proportionality and success. According to the proportionality condition the means used to prevent an attack can be permissible only if they are proportional to the interest at stake.1 According to the success condition, otherwise impermissible acts can be justified under the right to self-defence only if they are likely to succeed in preventing the perceived threat.2 These requirements should not always be interpreted narrowly. Sometimes people are permitted to kill culpable (...) aggressors in order to avoid a non-lethal harm. Sometimes people are permitted to take up arms to defend themselves against culpable aggressors they have little or no hope of .. (shrink)

The reception of the rational sciences, scientific practice, discourse and methodology into Arabic Islamic society proceeded in several stages of exchange with the transmitters of Iranian, Christian-Aramaic and Byzantine-Greek learning. Translation and the acquisition of knowledge from the Hellenistic heritage went hand in hand with a continuous refinement of the methods of linguistic transposition and the creation of a standardized technical language in Arabic: terminology, rhetoric, and the genres of instruction. Demonstration more geometrico, first introduced by the paradigmatic sciences-mathematics, astronomy, (...) mechanics-and adopted by philosophers embracing the cosmology of Neoplatonism, was complemented and superseded by the methods of syllogistic demonstration. Faced with the establishment of philosophy as a demonstrative science, which claimed absolute and universal knowledge, even the hermeneuti. (shrink)

In this paper it is shown that, in spite of their intuitive starting points, Kuipers' accounts lead to counterintuitive consequences. The counterintuitive results of Kuipers' account of H-D confirmation stem from the fact that Kuipers explicates a concept of partial (as opposed to full) confirmation. It is shown that Schurz-Weingartner's relevant-element approach as well as Gemes' content-part approach provide an account of full confirmation that does not lead to these counterintuitive results. One of the unwelcome results of Kuipers' account of (...) nomic truthlikeness is the consequence that a theory Y, in order to be more truthlike than a theory X (where Y and X are incompatible), must imply the entire nomic truth. It is shown how the relevant-element approach to truthlikeness avoids this result. (shrink)

Nelson Goodman (1906-1998) was one of the outstanding thinkers of the 20th century. In a memorial note, Hilary Putnam considers him to be ""one of the two or three greatest analytic philosophers of the post-World War II period"". Goodman has left his mark in many fields of philosophical investigation: Epistemology, Philosophy of Science, Logic, Metaphysics, the General Theory of Symbols, Philosophy of Languageand Philosophy of Art, all have been challenged and enriched by the problems he has shown up, the projects (...) he developed from them and the solutions he has suggested.

This article tries to point out the dialectical and paradoxical character of Eckhart’s thought, which permits him at once to affirm and to negate categories such as being, nothingness, personality, substance, origin, creation, image. In this way, Eckhart can unite a personal-theistic and a non-personal-atheistic view. A dialectical structure can also be seen in Eckhart’s ethics. Further, the dialectical interpretation can elucidate the ambivalence in the concept of the scintilla animae. The origin and aim of Eckhart’s dialectics proves to consist (...) in the concept of non-distinction. (shrink)

Among the many discussions Kierkegaard had with his Copenhagen contemporaries, his dispute with the Icelandic theologian Magnús Eiríksson over Kierkegaard’s theory of faith is particularly noteworthy. In the various drafts that Kierkegaard developed in response to Eiríksson’s critique, one finds insightful remarks not only on „the absurd“ and „the paradox“ as foundational concepts of Kierkegaard’s theory of faith, but also on the different perspectives of the various pseudonyms in this respect within the intricate tapestry of his writings. Notably, these drafts (...) were omitted from the authoritative Danish edition of Kierkegaard’s works, Søren Kierkegaards Skrifter (SKS), and have remained largely untranslated into other languages. In this workshop report, Kierkegaard’s drafts are made accessible and presented in their entirety for the first time in German translation. (shrink)

According to a plausible picture of information, to acquire information is to rule out possibilities. What is the nature of these possibilities? The most natural answer---that they are possible states of the world---seems to be refuted by the existence of informative truths that are necessary, and so don't rule out any real possibilities. This seems to show that informational contents cannot be identified with the real possibilities they eliminate. Real possibilities, it seems, are too coarse-grained to do the work of (...) informational contents. ;In the first part of the dissertation, I look at two defenses of the coarse-grained conception of content. First, Stalnaker has claimed that the informativeness of necessary truths can be explained within a two-dimensional semantic framework, in which necessary truths have contingent metalinguistic contents. In Chapter 1, I argue that this metalinguistic approach misconstrues the content of mathematical truths. Second, Stalnaker has claimed that we have independent reason to adopt a coarse-grained conception of content since naturalistic views of content such as indicator views allow only for coarse-grained contents. In Chapter 2, I argue that both indicator and teleological views allow for more fine-grained contents and that, given certain assumptions, they even require them. Together, these arguments show that the best attempt to explain the informativeness of necessary truths in terms of coarse-grained entities fails, and that naturalism gives us no reason for thinking that some other attempt will succeed. Instead of explaining informativeness in terms of the elimination of real possibilities, I claim, we should explain it in terms of the elimination of more fine-grained epistemic possibilities. ;In the second part of the dissertation, I describe the characteristic features of epistemic possibilities. Chapter 3 clarifies the relevant sense of epistemic possibility by distinguishing it from related senses that have gone under the same name. I argue that P is epistemically possible for a thinker at a time just in case an operative belief that P is compatible with his operative beliefs at this time, where beliefs are called compatible, not if their contents are compatible, but if the beliefs themselves are compatible in the sense that it is possible to have them at the same time. Since epistemic possibility in this sense is a matter of what it is possible to believe, I call it epistemic possibility in the believability sense. ;In Chapter 4, I turn to the question of what sort of thing epistemic possibilities are. I argue that epistemic possibilities can be defined in terms of, but not identified with, a certain kind of fine-grained content. (shrink)
