The biological species concept deals both with the meaning of the sexual species as a harmonious gene pool and with its protection against deleterious outbreeding (effected by isolating mechanisms). According to the Darwin-Muller-Mayr theory isolating mechanisms are acquired by incipient species during alloparty. Isolating mechanisms are not the result of ad hoc selection, but of a change of function of properties acquired during the preceding isolation of the incipient species. The role of behavioral properties (recognition) among (...) the isolating mechanisms has long been recognized and described by naturalists but was rejected as basis of a species definition for a number of valid reasons.

This collection of revised and new essays argues that biology is an autonomous science rather than a branch of the physical sciences. Ernst Mayr, widely considered the most eminent evolutionary biologist of the 20th century, offers insights on the history of evolutionary thought, critiques the conditions of philosophy to the science of biology, and comments on several of the major developments in evolutionary theory. Notably, Mayr explains that Darwin's theory of evolution is actually five separate (...) theories, each with its own history, trajectory and impact. Ernst Mayr, commonly referred to as the "Darwin of the 20th century" and listed as one of the top 100 scientists of all-time, is Professor Emeritus at Harvard University. What Makes Biology Unique is the 25th book he has written during his long and prolific career. His recent books include This is Biology: The Science of the Living World (Belknap Press, 1997) and What Evolution Is (Basic Books, 2002). (shrink)

Prompted by recent recognitions of the omnipresence of horizontal gene transfer among microbial species and the associated emphasis on exchange, rather than isolation, as the driving force of evolution, this essay will reflect on hybridization as one of the central concerns of nineteenth-century biology. I will argue that an emphasis on horizontal exchange was already endorsed by ‘biology’ when it came into being around 1800 and was brought to full fruition with the emergence of genetics in 1900. The true revolution (...) in nineteenth-century life sciences, I maintain, consisted in a fundamental shift in ontology, which eroded the boundaries between individual and species, and allowed biologists to move up and down the scale of organic complexity. Life became a property extending both ‘downwards’, to the parts that organisms were composed of, as well as ‘upwards’, to the collective entities constituted by the relations of exchange and interaction that organisms engage in to reproduce. This mode of thinking was crystallized by Gregor Mendel and consolidated in the late nineteenth-century conjunction of biochemistry, microbiology and breeding in agro-industrial settings. This conjunction and its implications are especially exemplified by Wilhelm Johannsen’s and Martinus Beijerinck’s work on pure lines and cultures. An understanding of the subsequent constraints imposed by the evolutionary synthesis of the twentieth century on models of genetic systems may require us to rethink the history of biology and displace Darwin’s theory of natural selection from that history’s centre.

In the six decades since the publication of Julian Huxley's Evolution: The Modern Synthesis, spectacular empirical advances in the biological sciences have been accompanied by equally significant developments within the core theoretical framework of the discipline. As a result, evolutionary theory today includes concepts and even entire new fields that were not part of the foundational structure of the Modern Synthesis. In this volume, sixteen leading evolutionary biologists and philosophers of science survey the conceptual changes that have emerged since (...) Huxley's landmark publication, not only in such traditional domains of evolutionary biology as quantitative genetics and paleontology but also in such new fields of research as genomics and EvoDevo. Most of the contributors to Evolution—The Extended Synthesis accept many of the tenets of the classical framework but want to relax some of its assumptions and introduce significant conceptual augmentations of the basic Modern Synthesis structure—just as the architects of the Modern Synthesis themselves expanded and modulated previous versions of Darwinism. This continuing revision of a theoretical edifice the foundations of which were laid in the middle of the nineteenth century—the reexamination of old ideas, proposals of new ones, and the synthesis of the most suitable—shows us how science works, and how scientists have painstakingly built a solid set of explanations for what Darwin called the "grandeur" of life.

A theory may be invalid, not owing to erroneous observations or the invocation of an inappropriate law, but because of the use of equivocal terms. This is demonstrated for Darwin's failed model of sympatric speciation through the principle of divergence.

Modern Darwinism is an elaboration of Darwin's original theories. The misunderstandings of the synthetic theory, on which recent attacks are based, are analyzed in detail. Six areas are described in which current theory modifies or amplifies Darwin's thinking. The rejection of an inheritance of acquired characters, the greater role assigned to chance in the production of genetic variability, the knowledge of the total separation of genotype and phenotype, and the clearer recognition of the role of the (...) individual as target of selection, are among the modern amplifications of the Darwinian theory. Remaining gaps in our understanding of evolution are specified. (shrink)

Theories postulating saltational evolution are a necessary consequence of essentialism. If one believes in constant types, only the sudden production of a new type can lead to evolutionary change. That such saltations can occur and indeed that their occurrence is a necessity is an old belief. Almost all of the theories of evolution described by H. F. Osborn in his From the Greek s to Darwin were saltational theories, that is, theories of the sudden origin of new kinds. The (...) Darwinian revolution did not end this tradition, which continued to flourish in the writings of Thomas H. Huxley, William Bateson, Hugo De Vries, J. C. Willis, Richard Goldschmidt, and Otto Schindewolf. Traces of this idea can even be found in the writings of some of the punctuationists. (shrink)

The cell is not only the structural, physiological, and developmental unit of life, but also the reproductive one. So far, however, this aspect of the cell has received little attention from historians and philosophers of biology. I will argue that cell theory had far-reaching consequences for how biologists conceptualized the reproductive relationships between germs and adult organisms. Cell theory, as formulated by Theodor Schwann in 1839, implied that this relationship was a specific and lawful one, that is, that (...) germs of a certain kind, all else being equal, would produce adult organisms of the same kind, and vice versa. Questions of preformation and epigenesis took on a new meaning under this presupposition. The question then became one of whether cells could be considered as autonomous agents producing adult organisms of a given species, or whether they were the product of external, organizing forces and thus only a stage in the development of the whole organism. This question became an important issue for nineteenth-century biology. As I will demonstrate, it was the view of cells as autonomous agents which helped both Charles Darwin and Gregor Mendel to think of inheritance as a lawful process. (shrink)

The prevalent reading of Darwin's achievements today is adaptationist. Darwin, so the usual story goes, succeeded in providing a naturalistic explanation of the fact that organisms are adapted to their environments, a fact that served and continues to serve, as a chief argument for creationism. This stands in a curious tension with Darwin's own fascination with phenomena whose adaptive value was problematic, like vicariance, ornaments, atavisms, and rudiments, as well as the various "contraptions" and "contrivances" by which (...) organisms take advantage of each other. I will explore this "dark side" of Darwin's evolutionism with respect to three themes that run through his work: heredity, which provided one of the corner stones of Darwin's theory and yet was defined as an essentially capricious, not necessarily adaptive force; mimicry, which for Darwin exemplified a general tendency of nature to produce deceiving semblances that turn actual relations on their head; and extinction, a phenomenon that pointed towards the redundancy of life, which for Darwin, in the double sense of that word, was both a fundamental condition and necessary consequence of evolution by natural selection.

The publication of Darwin's On the Origin of Species in 1859 ignited a public storm he neither wanted nor enjoyed. Having offered his book as a contribution to science, Darwin discovered to his dismay that it was received as an affront by many scientists and as a sacrilege by clergy and Christian citizens. To answer the criticism that his theory was a theory only, and a wild one at that, he published two volumes in 1868 to (...) demonstrate that evolution was obvious to anyone who cared to look at a bull in a pasture or a dog on a hearth. In response to those who insisted that species were distinct since creation, Darwin pointed to breeders of pigs and pigeons. In reply to those who protested that human intervention is one thing and natural selection another, he argued, "If organic beings had not possessed an inherent tendency to vary, man could have done nothing." To counter those who scorned his descriptions of species in exotic places, he submitted local evidence of cabbages and cauliflower. Based on a wide array of sources, from ancient pictographs to Polish roosters, from skins and from skeletons, from scientific journals and breeding manuals, Darwin assembled a mass of proof--and a hypothesis about species reversion that risked his reputation anew. The Variation of Animals and Plants under Domestication is a two-volume compilation of his thorough and intensive research and the revolutionary conclusions that resulted. The first portion of his work is dedicated to a meticulous analysis of various aspects of plant and animal life, including an inventory of varieties and their physical and behavioral characteristics, investigation of the impact of a species' surrounding environment and the role that both natural and forced changes in this environment have had. Darwin then turns to a richly detailed discussion of the roles of inheritance and crossing in the development of species. A wealth of illustrations further support and enhance his findings. This fascinating, invaluable, and courageous undertaking eventually formed the foundation for our current understanding of evolution. "In science as in politics the victors tend to write the history books. As a result, the record of the past is edited, intentionally or unintentionally, so that it focuses mainly on the precursors of contemporary orthodoxy. Such a focus may accurately represent the genealogy of modern ideas, but it almost inevitably misrepresents the historical experience of their progenitors... Even the powerful, persuasive, and ultimately triumphant theory of evolution by natural selection required not only defense, but repeated buttressing and revision. Variation showed Darwin hard at work on this rearguard action, using the materials he had at hand... His information was gleaned from the observations of fanciers, breeders, and amateur naturalists, as well as from the treatises of those on the cutting edge of zoology and botany. As hindsight narrows the historical spotlight, it imposes its own sense of hierarchy on the preoccupations of the past. But Darwin was interested in all of these topics, valued all of these sources, and belonged, to a greater or lesser extent, to all of these communities."--from the Introduction. (shrink)

Perhaps the most readable and accessible of the great works of scientific imagination, The Origin of Species sold out on the day it was published in 1859. Theologians quickly labeled Charles Darwin the most dangerous man in England, and, as the Saturday Review noted, the uproar over the book quickly "passed beyond the bounds of the study and lecture-room into the drawing-room and the public street." Yet, after reading it, Darwin's friend and colleague T. H. Huxley had a (...) different reaction: "How extremely stupid not to have thought of that." Based largely on Darwin's experience as a naturalist while on a five-year voyage aboard H.M.S. Beagle, The Origin of Species set forth a theory of evolution and natural selection that challenged contemporary beliefs about divine providence and the immutability of species. A landmark contribution to philosophical and scientific thought, this edition also includes an introductory historical sketch and a glossary Darwin later added to the original text. Charles Darwin grew up considered, by his own account, "a very ordinary boy, rather below the common standard of intellect." A quirk of fate kept him from the career his father had deemed appropriate--that of a country parson--when a botanist recommended Darwin for an appointment as a naturalist aboard H.M.S. Beagle from 1831 to 1836. Darwin is also the author of the five-volume work Zoology of the Voyage of the Beagle (1839) and The Descent of Man (1871). (shrink)

Most people who are regular consumers of psychoactive drugs are not drug addicts, nor will they ever become addicts. In neurobiological theories, non-addictive drug consumption is acknowledged only as a “necessary” prerequisite for addiction, but not as a stable and widespread behavior in its own right. This target article proposes a new neurobiological framework theory for non-addictive psychoactive drug consumption, introducing the concept of “drug instrumentalization.” Psychoactive drugs are consumed for their effects on mental states. Humans are able to (...) learn that mental states can be changed on purpose by drugs, in order to facilitate other, non-drug-related behaviors. We discuss specific “instrumentalization goals” and outline neurobiological mechanisms of how major classes of psychoactive drugs change mental states and serve non-drug-related behaviors. We argue that drug instrumentalization behavior may provide a functional adaptation to modern environments based on a historical selection for learning mechanisms that allow the dynamic modification of consummatory behavior. It is assumed that in order to effectively instrumentalize psychoactive drugs, the establishment of and retrieval from a drug memory is required. Here, we propose a new classification of different drug memory subtypes and discuss how they interact during drug instrumentalization learning and retrieval. Understanding the everyday utility and the learning mechanisms of non-addictive psychotropic drug use may help to prevent abuse and the transition to drug addiction in the future. (shrink)

Philipp Mayring und Norbert Rath greifen zentrale Fragen der heutigen Zeit auf: Was ist Glück? Woher kommt Glück? Wie kann man Glück erreichen? Zunächst geht es um klassische philosophische Ansätze – was verstehen antike Denker wie Demokrit, Platon, Aristoteles und Epikur sowie neuzeitliche Philosophen wie Montaigne, Kant, Hegel, Nietzsche, Freud und Adorno darunter? Es zeigt sich die Historizität der Glückskonzepte und die Notwendigkeit einer Kritik am »falschen« Glück. Psychologische Konzepte von Glück sind ebenso schillernd. Sie untersuchen empirisch, wie subjektive Glücksgefühle (...) zustande kommen, welche emotionalen, kognitiven und handlungsbezogenen Prozesse ihnen zu Grunde liegen und in welchen Situationen sich Menschen glücklich fühlen. Auch hier erscheint ein kritischer Standpunkt notwendig: Kritik an unterschiedlichen Glücksdefinitionen, Kritik an Erhebungsinstrumenten und Kritik an der Instrumentalisierung und Kommerzialisierung von Forschungsergebnissen. Gerade im Blick auf eine neuerdings weit verbreitete Positive Psychologie besteht ein Ideologieverdacht: Könnte es sich hier um kaum einlösbare Versprechungen einer affirmativen psychologischen Glücksforschung handeln? Philipp Mayring und Norbert Rath gehen diesen Fragen im Dialog zwischen Philosophie und Psychologie nach. Trotz der unterschiedlichen Herangehensweisen und Perspektiven der beiden Autoren zeigen sich erstaunliche Übereinstimmungen hinsichtlich einer kritischen Theorie des Glücks. (shrink)

According to a well-known view in the philosophy of mind, intentional attitudes by their very nature satisfy requirements of rationality (e.g. Davidson 1980; Dennett 1987; Millar 2004). This view (which I shall call Constitutivism) features prominently as the ‘principle of minimal rationality’ in de Sousa’s monograph The Rationality of Emotion (1987). By explicating this principle in terms of the notion of the formal object of an attitude, de Sousa articulates an interesting and original version of Constitutivism, which differs in important (...) respects from other extant versions. In this paper, I explore this version of Constitutivism against the background of recent developments in the theory of rationality and make explicit its ramifications for the long-standing dispute over whether the mind is essentially normative. My focus will be on how to conceive of the form of the rationality requirements that attitudes as such must satisfy according to this principle. I argue that, although de Sousa seems officially to endorse a structuralist conception of rationality, according to which these requirements are requirements of coherence, his considerations on formal objects suggest that they are more aptly conceived in terms of a reasons-responsive conception of rationality. I further argue that which of these two readings we choose makes a significant difference to the prospect of vindicating the essential normativity of mind by invoking the principle of minimal rationality.

This book discusses undercover reporting and deception in journalism, addressing the ethical issues encountered by professionals when deception is involved and providing an explanation of how high-profile cases have developed. Carson and Muller begin by examining how philosophical theories which form the basis of contemporary ethical codes for journalists, bear upon undercover reporting and questions of deception in the digital age. Drawing upon case studies such as Al Jazeera's undercover operation against the National Rifle Association in the US and (...) the One Nation political party in Australia, and Britain's Channel 4 infiltration of Cambridge Analytica, this book goes on to define and discuss the ethical concepts behind deception and betrayal and lays out an original ethical framework for undercover journalists facing related challenges in their work. Undercover Reporting, Deception and Betrayal in Journalism is an important research text for students and academics in journalism and media studies. (shrink)

A treasure trove of illuminating and entertaining quotations from the legendary naturalist Here is Charles Darwin in his own words—the naturalist, traveler, scientific thinker, and controversial author of On the Origin of Species, the book that shook the Victorian world. Featuring hundreds of quotations carefully selected by world-renowned Darwin biographer Janet Browne, The Quotable Darwin draws from Darwin’s writings, letters to friends and family, autobiographical reminiscences, and private scientific notebooks. It offers a multifaceted portrait that takes (...) readers through his youth, the famous voyage of the Beagle, the development of his thoughts about evolution, his gradual loss of religious faith, and the time spent turning his ideas into a well-articulated theory about the natural origin of all living beings—a theory that dangerously included the origin of humans. The Quotable Darwin also includes many of the key responses to Darwin’s ideas from figures across the social spectrum, scientists and nonscientists alike—and criticism too. We see Darwin as an innovative botanist and geologist, an affectionate husband and father, and a lively correspondent who once told his cousin that he liked to play billiards because “it drives the horrid species out of my head.” This book gives us an intimate look at Darwin at work, at home, as a public figure, and on his travels. Complete with a chronology of Darwin’s life by Browne, The Quotable Darwin provides an engagingly fresh perspective on a remarkable man who was always thinking deeply about the natural world.

Wenn ausgerechnet Pazifisten bei der Verfechtung ihrer Position aggressiv werden, so finden wir das besonders verstörend – jedenfalls verstörender als bei anderen Spannungen zwischen Theorie und Praxis. Woran liegt das? Meiner Ansicht nach kommen in diesem Fall drei Elemente zusammen, deren Mischung die pazifistische Position von innen bedroht: Während sich der hasserfüllte Pazifist schon beim Diskutieren schnell von negativen Emotionen fortreißen lässt, also alles andere als Willensstärke dokumentiert, verlangt er in seiner Theorie ein Höchstmaß an Willensstärke, und zwar gerade im (...) Umgang mit Emotionen. Dass er das nicht schafft, wirft nicht nur ein negatives Licht auf seine Person, sondern liefert Gründe gegen seine Theorie.

By pushing Descartes to more clearly explain the union of body and soul beyond the functioning of a ‘strong’ passion, namely sadness, Elisabeth wants Descartes to review his idea of the passions, and his understanding of the ‘theory of the four humors’. This chapter aims at showing that Descartes turns away from Galen’s theory of the humors, which he globally adopts in the 1633 Treatise of Man. With the shift in his conceptualization of the humors between this Treatise (...) and the Treatise of the Passions (1649), Descartes analyzed more specifically the inner feelings, consciousness, and the passions, by considering that a man is not simply a body, but a psychophysical being, with a body and a soul.

An important appeal of strategy-proofness is the robustness that it implies. Under a strategy-proof voting rule, every individual has an optimal strategy independently of the behavior of all other voters, namely truth-telling. In particular, optimal play is robust with respect to the beliefs voters may have about the type and the behavior of the other voters. Following Blin and Satterthwaite (Economet J Economet Soc 45(4):881–888, 1977), we call this logically weaker property “belief-independence.” In this paper, we give a number of (...) examples of voting rules that are belief-independent but not strategy-proof. However, we also show that belief-independence implies strategy-proofness under a few natural additional conditions. The notion of belief-independence naturally leads to a the strengthening of strategy-proofness to “robust” strategy-proofness which requires that no voter whose true preference may come from a restricted domain can benefit by submitting any unrestricted preference ordering given any unrestricted preference profile for all other voters. There are examples of strategy-proof voting rules (on a restricted domain) that are not robustly strategy-proof, but under natural additional conditions the two properties are shown to be equivalent.

Noam Chomsky is responsible for creating the field of research on grammatical theory in its present form, and he has also been material in providing frameworks for syntactic analysis, from early transformational grammar to current implementations of the minimalist program. Against the background of these syntactic frameworks, a huge number of constraints on grammatical dependencies have been proposed over the years. Constraints initially suggested by Chomsky have a more troubled history, in the sense that they have variously been claimed (...) to be empirically falsified, considered conceptually flawed, or simply consigned to oblivion. This chapter aims to argue that some of the constraints arguably belonging to this latter group can, upon closer scrutiny, in fact be shown to be at the heart of current syntactic theory, and qualify as “good”, whereas this does not necessarily hold for constraints in the former group.

Historians and philosophers of science have interpreted the taxonomic theory of Carl Linnaeus as an ‘essentialist’, ‘Aristotelian’, or even ‘scholastic’ one. This interpretation is flatly contradicted by what Linnaeus himself had to say about taxonomy in Systema naturae , Fundamenta botanica and Genera plantarum . This paper straightens out some of the more basic misinterpretations by showing that: Linnaeus’s species concept took account of reproductive relations among organisms and was therefore not metaphysical, but biological; Linnaeus did not favour classification (...) by logical division, but criticized it for necessarily failing to represent what he called ‘natural’ genera; Linnaeus’s definitions of ‘natural’ genera and species were not essentialist, but descriptive and polytypic; Linnaeus’s method in establishing ‘natural’ definitions was not deductive, but consisted in an inductive, bottom-up procedure of comparing concrete specimens. The conclusion will discuss the fragmentary and provisional nature of Linnaeus’s ‘natural method’. I will argue in particular that Linnaeus opted for inductive strategies not on abstract epistemological grounds, but in order to confer stability and continuity to the explorative practices of contemporary natural history.

My philosophical case study concerns textbook presentations of the theory of demand. Does this theory contain anything more than just a collection of tautologies? In order to determine its empirical content, it must be viewed holistically. But then, the theory implies false factual claims. We can avoid this result by embracing the theory’s normative character. The resulting consequences will be illuminated with the new autodetermination thesis recently proposed in the philosophy of physics by Oliver Timmer. Applying (...) his ideas to the theory of demand reveals that the statements of this discipline simultaneously concern both values and facts. (shrink)

Using Sneed's metatheory an attempt is made to reconstruct Hodgkin and Huxley's theory of excitation of cell membranes. The structure of this theory is uncovered by defining set-theoretical predicates for the partial potential models, potential models, and models of the theory. The function of permeability is said to be the only theoretical function with respect to this theory. The main underlying assumptions of the theory are briefly outlined.

Our self-understanding as human agents includes a commitment to three crucial claims about human agency: that agents must be active, that actions are part of the natural order of the universe, and that intentional actions can be explained by the agent's reasons for acting. While all of these claims are indispensable elements of our view of ourselves as human agents, they are in continuous conflict and tension with one another, especially once one adopts the currently predominant view of what the (...) natural order must be like. One of the central tasks of philosophy of action consists in showing how, despite appearances, these conflicts can be resolved and our self-understanding as agents be vindicated. The mainstream of contemporary philosophy of action holds that this task can only be fulfilled by an event-causal reductive view of human agency, paradigmatically embodied in the so-called 'standard model' developed by Donald Davidson. Erasmus Mayr, in contrast, develops a new agent-causal solution to these conflicts and shows why this solution is superior both to event-causalist accounts and to Von Wright's intentionalism about agency. He offers a comprehensive theory of substance-causation on the basis of a realist conception of powers, which allows one to see how the widespread rejection of agent-causation rests on an unfounded 'Humean' view of nature and of causal processes. At the same time, Mayr addresses the question of the nature of reasons for acting and complements its substance-causal account of activity with a non-causal account of acting for reasons in terms of following a standard of success.

A monumental work on the flow of time, from the universe's creation to "Now," by the best-selling author of Physics for Future Presidents. "Now" is a simple concept--you're reading this sentence now. Yet a real definition of "now" has eluded even the great Einstein. We know that time stretches and is affected by gravity and velocity. Yet, as eminent physicist Richard A. Muller points out, it is only today that we have all the physics at hand--relativity, entropy, entanglement, antimatter, (...) and the Big Bang--to explain the flow of time. With these building blocks in place, Muller reaches a startling conclusion: our expanding universe is continuously creating not only new space but also new time. The front edge of this new time is what we call "now," and this moment is truly unique--it is the only moment in which we can exercise our free will. Muller's thought-provoking vision is a powerful counter to established theories in science and philosophy, and his arguments will spark major debate about the most fundamental assumptions of our universe.

Cognition is commonly taken to be computational manipulation of representations. These representations are assumed to be digital, but it is not usually specified what that means and what relevance it has for the theory. I propose a specification for being a digital state in a digital system, especially a digital computational system. The specification shows that identification of digital states requires functional directedness, either for someone or for the system of which it is a part. In the case or (...) digital representations, to be a token of a representational type, where the function of the type is to represent.

In 1859, Charles Darwin published his best-known work On The Origin of Species. Darwin's book introduced his revolutionary theory of evolution, a work that Darwin had meticulously developed spanning two decades. Controversial at the time of publishing, Darwin's theory sparked international debate surrounding his theory of natural selection, however this historical text is arguably the most important book of its kind on biological evolution.

Rollback arguments focus on long sequences of actions with identical initial conditions in order to explicate the luck problem that indeterminism poses for libertarian free will theories (i.e. the problem that indeterministic actions appear arbitrary in a free-will undermining way). In this paper, I propose a rollback argument for probability incompatibilism, i.e. for the thesis that free will is incompatible with all world-states being governed by objective probabilities. Other than the most prominently discussed rollback arguments, this argument explicitly focusses on (...) the ability to act otherwise. It argues that the negligible probability of the relative frequencies in overall rollback patterns being relevantly different indicates that even the ability to act otherwise with regard to individual actions is not free-will enabling. My proposed argument provides probability incompatibilists with a tool to argue against a classical event-causal response to the luck problem, while it can still motivate an agent-causal response to it.

May lethal autonomous weapons systems—‘killer robots ’—be used in war? The majority of writers argue against their use, and those who have argued in favour have done so on a consequentialist basis. We defend the moral permissibility of killer robots, but on the basis of the non-aggregative structure of right assumed by Just War theory. This is necessary because the most important argument against killer robots, the responsibility trilemma proposed by Rob Sparrow, makes the same assumptions. We show that (...) the crucial moral question is not one of responsibility. Rather, it is whether the technology can satisfy the requirements of fairness in the re-distribution of risk. Not only is this possible in principle, but some killer robots will actually satisfy these requirements. An implication of our argument is that there is a public responsibility to regulate killer robots ’ design and manufacture. (shrink)

Gerechtigkeit gilt als Kardinaltugend für ein gutes und richtiges Leben. Was aber bedeutet sie inhaltlich und wie lässt sie sich begründen? Der gedankliche Mittelpunkt der Darstellung ist die epochale Neubestimmung der Gerechtigkeit durch John Rawls. Seine Theorie der Gerechtigkeit hat zu vielen Diskussionen, Weiterführungen und Gegenentwürfen Anlass gegeben, die exemplarisch vorgestellt und vier Fragestellungen zugeordnet werden: Ist ein Gesellschaftsvertrag als Grundvoraussetzung der Theorie unabdingbar? Muss nicht die Gemeinschaft als Ort der Gerechtigkeitsvorstellungen stärker betont werden? Ist der Stellenwert, den Rawls der (...) Gleichheit zuschreibt, angemessen? Gewährt er der Freiheit einen adäquaten Raum? Den Abschluss bildet ein argumentationsethischer situationsbezogener Ansatz. (shrink)

This essay discusses Kant and Hegel’s philosophies of action and the place of action within the general structure of their practical philosophy. We begin by briefly noting a few things that both unite and distinguish the two philosophers. In the sections that follow, we consider these and their corollaries in more detail. In so doing, we map their differences against those suggested by more standard readings that treat their accounts of action as less central to their practical philosophy. Section 2 (...) discusses some central Kantian concepts. In Section 3, we take a closer look at the distinction between internal and external action, as found in Kant’s philosophy of morality and legality. In Section 4, we turn to Hegel and his distinctions between abstract right, morality, and ethical life, as well as the location of his account of action within his overall theory of morality. We discuss the distinction between Handlung and Tat, and non-imputable consequences. The overall aims of our essay are to shed light on some puzzles in Kant and Hegel’s conceptions and to examine where their exact disputes lie without taking a stand on which philosophy is ultimately the most satisfactory.

Our reply to Fabian Freyenhagen’s article “Was ist orthodoxe Kritische Theorie?” (DZPhil 65.3 [2017], 456-469) raises the question whether his proposal that Critical Theory only “be adequately and appropriately critical” without a program of justification spares the search for any general criteria. Answering negatively we conversely want to recall, particularly with regard to Horkheimers’s and Adornos’s Dialectic of Enlightment as well as Habermas‘s concept of an emancipatory interest, that such a criterion as a normative foundation of critique is crucial (...) not only for systematical purposes, but also recognised as necessary in this respect by Adorno, who Freyenhagen wants to play off against programs of justification. Critical Theory needs to be clear in this respect. Against this background we are questioning Freyenhagen‘s recourse to an “interest in abolishing social injustice” as the “only criterion for Critical Theory.” Because Freyenhagen ignores the fact that Critical Theory has been understood by its representatives in a twofold manner – as a theoretical program of justification for one and secondly as a cultural diagnosis – his plea for an orthodox Critical Theory is endangered by decisionism.

Goethes Protest gegen Newtons Theorie des Lichts und der Farben ist besser, als man gemeinhin denkt. Man kann diesem Protest in den wichtigsten Elementen folgen, ohne Newton in der physikalischen Sache unrecht zu geben. Laut meiner Interpretation hat Goethe in Newtons wissenschaftsphilosophischer Selbsteinschätzung eine entscheidende Schwäche aufgedeckt: Newton glaubte, mithilfe prismatischer Experimente beweisen zu können, dass das Licht der Sonne aus Lichtstrahlen verschiedener Farben zusammengesetzt sei. Goethe zeigt, dass dieser Übergang vom Beobachtbaren zur Theorie problematischer ist, als Newton wahrhaben wollte. (...) Wenn Goethe darauf beharrt, dass uns der Übergang zur Theorie nicht von den Phänomenen aufgezwungen wird, dann kommt dadurch unser eigener, freier und kreativer Beitrag zur Theorie-Bildung ans Tageslicht. Und diese Einsicht Goethes gewinnt eine überraschende Schärfe, weil Goethe plausibel machen kann, dass sich alle entscheidenden prismatischen Experimente Newtons ebenso gut mit einer alternativen Theorie vereinbaren lassen. Wenn ich recht sehe, war Goethe der erste Wissenschaftsphilosoph, der mindestens eine empirisch äquivalente Alternative zu einer wohletablierten physikalischen Theorie gesehen hat: Damit war Goethe seiner Zeit um ein gutes Jahrhundert voraus.
