It is commonly thought that the distinction between subjectively valid judgements of perception and objectively valid judgements of experience in the Prolegomena is not consistent with the account of judgement Kant offers in the B Deduction, according to which a judgement is ‘nothing other than the way to bring given cognitions to the objective unity of apperception’. Contrary to this view, I argue that the Prolegomena distinction maps closely onto that drawn between the mathematical and dynamical principles in the System (...) of Principles: Kant’s account of the Prolegomena distinction strongly suggests that it is the Analogies of Experience that make it possible for judgements of perception to give rise to judgements of experience. This means that judgements of perception are objectively valid with regard to the quantity and quality of objects, and subjectively valid with regard to the relation they posit between objects. If that is the case, then the notion of a judgement of perception is consistent with the B Deduction account of judgement. (shrink)

This book investigates Aristotle’s views on abstraction and explores how he uses it. In this work, the author follows Aristotle in focusing on the scientific detail first and then approaches the metaphysical claims, and so creates a reconstructed theory that explains many puzzles of Aristotle’s thought. Understanding the details of his theory of relations and abstraction further illuminates his theory of universals. Some of the features of Aristotle’s theory of abstraction developed in this book include: abstraction is a relation; perception (...) and knowledge are types of abstraction; the objects generated by abstractions are relata which can serve as subjects in their own right, whereupon they can appear as items in other categories. The author goes on to look at how Aristotle distinguishes the concrete from the abstract paronym, how induction is a type of abstraction which typically moves from the perceived individuals to universals and how Aristotle’s metaphysical vocabulary is "relational.’ Beyond those features, this work also looks at how of universals, accidents, forms, causes and potentialities have being only as abstract aspects of individual substances. An individual substance is identical to its essence; the essence has universal features but is the singularity making the individual substance what it is. These theories are expounded within this book. One main attraction in working out the details of Aristotle’s views on abstraction lies in understanding his metaphysics of universals as abstract objects. This work reclaims past ground as the main philosophical tradition of abstraction has been ignored in recent times. It gives a modern version of the medieval doctrine of the threefold distinction of essence, made famous by the Islamic philosopher, Avicenna. (shrink)

The dynamic nature of physics cannot be captured through an exclusive focus on the static mathematical formulations of physical theories. Instead, we can more fruitfully think of physics as a set of distinctively social, cognitive, and theoretical/methodological practices. An emphasis on practice has been one of the most notable aspects of the recent “naturalistic turn” in general philosophy of science, in no small part due to the arguments of many feminist philosophers of science. A major project of feminist philosophy of (...) physics has been to shine a critical light on the social and cognitive practices in physics, and how those ultimately influence other aspects of the science. Here we argue that traditional philosophy of physics has focused exclusively on the theoretical/methodological practices of physics, and that feminist philosophy of physics seeks to broaden the focus to include the social and cognitive practices as well.

In times of current crisis, the voices of women are needed more than ever. The accumulation of war and environmental catastrophes teaches us that exploitation of people and nature through violent appropriation and enrichment for the sake of short-term self-interest exacts its price. This book presents contributions on the currently most relevant and most urgent issues: reshaping the economy, environmental problems, technology and the re-reading of history from the non-western and western tradition. With an outlook into the problems of class, (...) race and gender in its intersectional framing, the collection offers a unique overview of current research in these fields and contributes to the renewal and contemporary presentation of feminist thought from partly concrete perspectives with regard to factual issues.

This dissertation addresses the problem of how to evaluate and compare the theories that inform diverse approaches to psychotherapy. It is argued that the field needs a superordinate epistemology to provide legitimacy for its theories and for the clinical work that these theories guide. Such a superordinate epistemology would occupy a higher level of analysis than the theories it is used to evaluate. ;Using a constructivist framework, it is argued that much of the epistemological confusion currently characterizing clinical psychology can (...) be traced to a traditional failure to distinguish among levels of analysis when evaluating clinical psychology theories. It is demonstrated that evaluations of such theories often conflate theory and epistemology. ;The received view of a natural science epistemology and hermeneutics provide the usual terms in which epistemology is debated. These are found inadequate to fill the necessary role of superordinate epistemology. The received view is criticized, in part, for "bracketing" the domain of meaning, and hermeneutics is criticized, in part, for "bracketing" the domain of extra-linguistic reality. For these reasons, it is shown that neither of these approaches can be considered to be superordinate to clinical theories. ;Next, some preliminary theoretical groundwork for the development of a constructivist superordinate epistemology for clinical psychology is offered. The domain of clinical psychology is defined as the conjunction of the domains of meaning and reality. A constructivist reformulation of the role of empirical research and observational knowledge is outlined. A reconceptualization of clinical theories as narratives and "expert languages" is suggested as well. ;It is argued that theoretical propositions first should be evaluated according to whether they conform to observational knowledge about the unintentional constraints on human intentionality. Then theories should be evaluated according to the coherence of their accounts of the transactions between the domains of meaning and reality. The hermeneutic circle is suggested as a methodology for choosing among different interpretations in a given therapeutic encounter. ;Finally, some directions for future work are suggested. (shrink)

What is early modern philosophy? Two interpretative trends have predominated in the related literature. One, with roots in the work of Hegel and Heidegger, sees early modern thinking either as the outcome of a process of gradual rationalization (leading to the principle of sufficient reason, and to "ontology" as distinct from metaphysics), or as a reflection of an inherent subjectivity or representational semantics. The other sees it as reformulations of medieval versions of substance and cause, suggested by, or leading to, (...) early modern scientific developments. -/- This book proposes a rather different kind of explanation. It suggests that the concept of relation, specifically that of dyadic, anti-symmetrical relations, can throw light on a wide variety of developments in early modern thought, such as those concerning causality, sense perception, temporality, and the mereological approach to substance. The book argues that these relations are grounded in an interpretation of causal influence, and not in semantic theories or subjectivity. -/- Furthermore, if it is correct that the problem of unity was, for most of classical antiquity, what the problems of motion, causality and perception were for early modern thinkers, then early modern thought is much closer to the thought of Aristotle than is commonly supposed. The genesis of early modern thought might instead be taken to have occurred in opposition to one aspect of the thought of Duns Scotus (an aspect that lives on in contemporary Neo-Aristotelianism), and that can be explained once the relational perspective examined here is taken into account.

Structural realism as developed by John Worrall and others can claim philosophical roots as far back as the late 19th century, though the discussion at that time does not unambiguously favor the contemporary form, or even its realism. After a critical examination of some aspects of the historical background some severe critical challenges to both Worrall's and Ladyman's versions are highlighted, and an alternative empiricist structuralism proposed. Support for this empiricist version is provided in part by the different way in (...) which we can do justice to Worrall's original demands and in part by the viewpoint it provides (in contrast to e.g. Michael Friedman's) on the stability maintained through scientific theory change.

According to Ernst Cassirer, the transition from the concept of substance to that of mathematical function as a guide of knowledge coincided with the end of ancient and the beginning of modern theoretical thought. In the first part of this article we argue that a similar transition has also taken place in the practical sphere, where mathematical function occurs in one of its specific forms, which is that of the algorithm concept. In the second part we argue that with the (...) rise of modernity the idea of substance and the related concepts of category and classification, which are deeply embedded in western culture, have not been totally supplanted by that of function. The intertwining of the concepts of substance and function has generated contradictory hybrids. These hybrids are used as a key for the understanding of the different repercussions of algorithmic logic on society in terms of social integration. (shrink)

This article is both a comment on Neyland’s ‘On organizing algorithms’ and a supplementary note to our ‘The concept of algorithm as an interpretative key of modern rationality’. In the first part we discuss the concepts of algorithm and recursive function from a different perspective from that of our previous article. Our cultural reference for these concepts is once again computability theory. We give additional arguments in support of the idea that a culture informed by an algorithmic logic has promoted (...) modern rationality both in science and in society. We stress again the importance of distinguishing between algorithms applied to quantifiable entities such as space, time and value and those applied to ontological entities such as human actions. In the second case, the algorithm is applied outside its domain of definition and leads to social disaggregation. (shrink)

Over the course of three books—Wandering Significance, Physics Avoidance, and most recently Imitation of Rigor—Mark Wilson seeks to rectify what he takes to be a century of error regarding analytic philoso-phy’s understanding of scientific theorizing. This is largely framed in terms of a sustained attack on what Wilson terms ‘theory T thinking’, which he uses to refer to a melange of philosophical tendencies that he argues fail to do justice to the nuances of how world–theory relations are forged in the (...) physical sciences. In its place, Wilson puts forward an intricate account of the shifting explanatory strategies scientists and mathematicians utilize, strategies that result in the morphing of the semantic import of our scientific terms. In the aftermath an important question emerges: what is to become of scientific realism? Despite numerous pronunciations of his own ‘stout’ realist stance, it remains unclear what Wilson’s position might actually entail. -/- I first sketch Wilson’s disputes with theory T thinking and demonstrate how his rejection of the main tenets of most contemporary realist accounts leaves a question as to what his own realist avowals could mean, further arguing that these are largely attempts to distance himself from any whiff of neo-Kantianism. In the remainder of the article, I turn to discuss a neo-Kantian account that I argue is both complementary to Wilson’s viewpoint and provides a foundation for a post-theory T realism: Ernst Cassirer’s account of concept-formation in the natural sciences. By fleshing out Cassirer’s notion of the transformation of the given and the particular role he attributes to theoretical idealization, I reconstruct his account in a way that draws out a number of fruitful parallels between his philosophy and Wilson’s. The upshot is that a post-theory T scientific realism can plausibly be brought into line with neo-Kantian conceptions. (shrink)

Bourdieu’s concept of habitus claims to solve the problem of the individual/society duality. However, the concept of habitus appears to be inadequate to explain the idiosyncratic features of individual field actors’ practices. In this article, I argue that to explain the particularity of individual habitus, we must appreciate the operationalization of relational logic in field theory. I further argue that individuals learn to prediscursively identify certain types of practices as meaningful for a given field position because of their embodied experiences (...) of movements within the historically specific relational structure of the field. Thus, the same individual can exhibit multiple and even contradictory practices depending on the person’s relational position in the field. I illustrate this insight by discussing the political habitus of the first prime minister of India, Jawaharlal Nehru. (shrink)

The ArgumentRecent archival research has brought about a new understanding of the import of Einstein's puzzling remarks (1916) attributing a physical meaning to general covariance. Debates over the scope and meaning of general covariance still persist, even within physics. But already in 1921 Cassirer identified the significance of general covariance as a novel stage in the development of the criterion of objectivity within physics; an account of this development, and its implications, is the primary task undertaken in his monograph of (...) “epistemological considerations” on the theory of relativity. Cassirer's assessment is correct: general covariance, understood as an injunction against dynamical theories with background elements, is a “limiting heuristic principle” guiding Einstein's fundamental conception of a “complete field theory”; as such, it underlies a “separation principle” built into the conceptual framework of the EPR criticism of quantum mechanics. In conclusion, a further parallel is noted: mutual recognition that the principle of general covariance is but a form of “anthropomorphism.”. (shrink)

Based on the design of many modern chemical instruments, information about a specimen is retrieved after the specimen undergoes agitation, manipulation and disturbance of its internal state. But can we retain the traditional ideal that instruments should reveal properties that are definable independently of all modes of detection? In this paper I argue that the capacity of chemical instruments to convert experimental phenomena to information places constraints on the way in which the specimen is characterized. During research, the specimen is (...) defined by those properties which permit its detection. Based on modern instrumentation, this constraint necessitates a conception of the specimen as a reactive system of dynamical properties. The dream of a purely transparent detection process violates the design of chemical instruments. This mutual dependence of instrument and specimen is illustrated by empirical studies of the geometrical configuration of DNA. (shrink)

At the turn of the twentieth century, a number of philosophers introduced the idea of philosophical research on cognition that could enter into competition with psychology, which was developing into an autonomous discipline at that time. In view of the problems of the traditional but still prevailing associationist theory, Ernst Cassirer demanded a more sophisticated theory that could explain the human ability to concentrate one's thoughts on a topic, such as a problem or a task. He presented a representational theory (...) of mind to explain this ability. This paper explicates the scope of this theory and Cassirer's idea of interdisciplinary cooperation between philosophers and psychologists. (shrink)

Marburg Neo-Kantianism has attracted substantial interest among contemporary philosophers drawn by its founding idea that the success of advanced theoretical science is a given fact and it is the task of philosophical inquiry to ground the objectivity of scientific achievement in its a priori sources (Cohen and Natorp 1906, p. i). The Marburg thinkers realized that recent advances and developments in the mathematical sciences had changed the character of Kant’s transcendental project, demanding new methods and approaches to establish the objectivity (...) of the latest insights into physical reality. Hermann Cohen, one of the founders of the Marburg School, attempted to base the objectivity of science on the concepts of .. (shrink)

The ArgumentBiology, understood in turn-of-the-century Germany to include psychology, held a central but enigmatic place in the philosopher Ernst Cassirer's work. From his earliest studies with Hermann Cohen through his long engagement with the theoretical biology of Jakob von Uexküll and Adolf Meyer-Abich, Cassirer consistently used the history and practice of biology to examine and delineate a set of characteristic tensions between the natural and cultural sciences. This paper examines Cassirer's treatment of this theme by addressing two contrasting interpretations he (...) gave — in hisPhilosophy of Symbolic Forms and in hisEssay on Man — to the benchmark case from empirical psychology of the “talking” horse “Clever Hans.” The original case involved the horse's ability to signal answers to remarkably complex questions by stamping its hooves, an ability that ultimately appeared to rest on a capacity to detect extremely minute unintentional movement cues in its auditors as it reached the appropriate answer. Due to both Cassirer's shifting description of the case within his philosophy and the case's inherent polyvalence, Cassirer's remarks provide a useful window onto the social, epistemological, and stylistic meaning of his “unified” philosophy of human culture and science.

We seek to elucidate the philosophical context in which one of the most important conceptual transformations of modern mathematics took place, namely the so-called revolution in rigor in infinitesimal calculus and mathematical analysis. Some of the protagonists of the said revolution were Cauchy, Cantor, Dedekind,and Weierstrass. The dominant current of philosophy in Germany at the time was neo-Kantianism. Among its various currents, the Marburg school (Cohen, Natorp, Cassirer, and others) was the one most interested in matters scientific and mathematical. Our (...) main thesis is that Marburg neo-Kantian philosophy formulated a sophisticated position towards the problems raised by the concepts of limits and infinitesimals. The Marburg school neither clung to the traditional approach of logically and metaphysically dubious infinitesimals, nor whiggishly subscribed to the new orthodoxy of the “great triumvirate” of Cantor, Dedekind, and Weierstrass that declared infinitesimals conceptus nongrati in mathematical discourse. Rather, following Cohen’s lead, the Marburg philosophers sought to clarify Leibniz’s principle of continuity, and to exploit it in making sense of infinitesimals and related concepts. (shrink)

The paper focuses on the role of relativistic ideas in Wittgenstein’s philosophy. In particular, it focuses on On Certainty (1969), where in (305), Wittgenstein explicitly invokes Einstein’s theory of relativity: “Here once more there is needed a step like the one taken in relativity theory.” The aim of the paper is to establish a connection between Wittgenstein and Einstein that is both theoretically and exegetically sound. In particular, the paper argues that Wittgenstein’s reaction to scepticism closely resembles Einstein’s reaction to (...) the ether. (shrink)

Against Thomas Mormann's argument that differential topology does not support Carnap's conventionalism in geometry we show their compatibility. However, Mormann's emphasis on the entanglement that characterizes topology and its associated metrics is not misplaced. It poses questions about limits of empirical inquiry. For Carnap, to pose a question is to give a statement with the task of deciding its truth. Mormann's point forces us to introduce more clarity to what it means to specify the task that decides between competing hypotheses (...) and in what way such a task may be both in practice and/or in principle impossible to carry out.

The ArgumentErnst Cassirer's fundamental conception of symbolism (symbolic pregnance) derives from what may be called a bio-medical model of semiotics, not a linguistic one. He employs both models in his philosophy of symbolic forms, but his notion of the “prototype and model of symbolism” was not derived from linguistics. The sources for his conception of symbolism include the ethnographic and anthropological literature he discovered in Aby Warburg's (1866–1929) Hamburg research library, findings of medical research on aphasia and related conditions, particularly (...) the work of Kurt Goldstein (1878–1965) and the theoretical biology of Jacob von Uexküll (1864–1944). The linguistic model of semiotics regards the bond between the signifier and the signified as purely arbitrary and conventional, but Cassirer traced meaning back to a “natural symbolism” of image-like configurations in bodily feeling and perception. In this way, his doctrine of symbolism assumed a form that undercut the distinction between philosophical Naturalism and Idealism. This helps to explain why in later years Cassirer developed his theory of Basic Phenomena. Cassirer's notion of the “prototype and model of symbolism” illustrates his method of thought, which eschews pure argument in favor of interaction with empirical research. (shrink)

In the English-speaking world it is, unfortunately, only known through the fourth volume, and when this appeared in English in 1950 it met (...) with a negative, even hostile, reception. (shrink)

ABSTRACT In the current debate between scientific realism and empiricism, both sides seem to embrace some sort of structuralism as an important component of their descriptions of science. The structural realism is generally presented in two versions: one ontic and the other epistemic. It has been argued that that epistemic structural realism is close, if not identical, to a Kantian approach. We aim to show that this is not the case, since ESR, being fundamentally a realist position, cannot be fully (...) consistent with a transcendental approach. Such a position is better called transcendental structuralism, an alternative that we believe is worth being investigated on its own. In this paper, we will take Henry Allison's interpretation of transcendental idealism as a starting point to establish the distinctions between ESR and TS.RESUMO No debate atual entre realismo científico e empirismo, ambos os lados parecem abraçar algum tipo de estruturalismo como um componente importante de suas descrições sobre a ciência. O realismo estrutural é geralmente apresentado em duas versões: uma ôntica e outra epistêmica. Tem-se argumentado que o realismo estrutural epistêmico, por sua vez, é próximo, se não idêntico, a uma abordagem kantiana. Nosso objetivo neste artigo é mostrar que esse não é o caso. Sendo o ESR fundamentalmente uma posição realista, queremos defender que ele não pode ser totalmente compatível com uma abordagem transcendental. Uma posição kantiana mais coerente é aqui defendida sob o nome de estruturalismo transcendental. Neste artigo, partiremos da interpretação de Henry Allison do idealismo transcendental para estabelecer as devidas distinções entre ESR e TS. (shrink)

In science as in mathematics, it is popular to know little and resent much about category theory. Less well known is how common it is to know little and like much about set theory. The set theory of almost all scientists, and even the average mathematician, is fundamentally different from the formal set theory that is contrasted against category theory. The latter two are often opposed by saying one emphasizes Substance, the other Form. However, in all known systems of mathematics (...) throughout history, mathematicians have moved fluidly between ideas conceived of as thing-like, property-like, and process-like. On the other hand one way to advance science is to better distinguish between thing, property, and process. All this constitutes a distracting background for those interested in, or distressed by, the possible application of category theory to science, and to mathematics as well. (shrink)

The ArgumentCassirer's analyses of twentieth-century physics from the perspective of the philosophy of science focuses on the concept of the object of scientific experience. Within his concept of functional knowledge, he takes a structural stance and claims that it is specifically this concept of the object that has paved the way for modern science. This article aims, first, to show that Cassirer's interpretation of Felix Klein's “Erlanger Programm” provided the impetus for this view. Then, it analyzes Kant's conception of objectivity (...) in order to examine whether Cassirer can rightfully claim that his view is a further development of transcendental principles. Finally, it is argued that it is Cassirer's concept of the object that enables him to integrate one decisive feature of scientific progress, namely, the increasinggeneralizationof the basic concepts of a science, into his conception of knowledge. This is illustrated in more detail through the example of the progression from Newton's mechanics to relativity theory. (shrink)

From the very beginning, it has been difficult to extract a smooth narrative from the complex plot of Bakhtin’s life and work. Early attempts to do this proposed an unconvincing distinction between a private philosophical Bakhtin and the man who wrote compelling and innovative work on the philosophy of language, the stylistics of the novel, and the culture of carnival. The 7-volume Sobranie sočinenij (1996–2012) both frustrates and supports this simplifying narrative. The texts it presents, many radically different from earlier (...) published versions, suggest that Bakhtin’s commitment to the stylistics of the novel was permanent and enduring and that its sociological colouring was more than strategic. The notes and commentary, however, seek to corral the energy of the material, by persistently interpreting Bakhtin’s works as separable into philosophical kernels and sociological/stylistic shells.

The foundations of systematics lie in ontology, not in subjective epistemology. Systems and their elements should be distinguished from classes; only the latter are constructed from similarities. The term classification should be restricted to ordering into classes; ordering according to systematic relations may be called systematization.The theory of organization levels portrays the real world as a hierarchy of open systems, from energy quanta to ecosystems; followingHartmann these systems as extended in time are considered the primary units of reality. Organization levels (...) should be distinguished from levels of differentiation within each organization level.Certain biological systems, such as species, continue to be misinterpreted as classes, particularly by logicians unfamiliar with modern biological theory. Replacement of Aristotelian definitions of species by “polytypic” definitions achieves nothing, because species are individual systems which can be defined from an ontological viewpoint only as wholes. The dispute whether classes are real per se or only in individuals is of no scientific importance; irrespective of which view is taken, any ordering of physical objects into classes constitutes an hypothesis about the structure of the real world.The distinction between essential and contingent characters is relevant only to classification. There are no universal rules for evaluating characters for purposes of systematization. Character statements do not form separate linear sequences. The search for “unit characters” in an absolute sense is futile. All real characters are reducible to relations and are in principle measurable, although there are limitations on the extent to which this can be presently achieved.The concept of the sexual species is fundamental to theories of biosystematics. Sexual species may be defined as lineages consisting at any given time of series of populations between which genetic exchange can occur and delimited in time by two successive processes of speciation. Linnaean nomenclature needs modification; in its traditional form it is appropriate only to non-truncated hierarchies, whereas real phylogenies form truncated hierarchies. In consequence of the distinction between systematization and classification it is concluded that, while taxa may be classified into age classes or evolutionary grades, their limits as taxa can be no different in either case. Classification into evolutionary grades remains an imprecise endeavour, since no general measure of evolutionary differentiation has been devised.The spatial and temporal extent of ecosystems, the postulated basic units of ecosystematics, remains unclarified. Nevertheless there are grounds for expecting progress in this field as the energetic relations between organisms become better understood. Biotic communities are not “abstract” classes, but systematic units. Physiognomic classification should not be confused with systematization of plant communities; both approaches contribute to an understanding of vegetational structure. (shrink)

In his Zur Einstein’schen Relativitätstheorie, Ernst Cassirer presents relativity theory as the last manifestation of the tradition of the “physics of principles” that, starting from the nineteenth century, has progressively prevailed over that of the “physics of models.” In particular, according to Cassirer, the relativity principle plays a role similar to the energy principle in previous physics. In this article, I argue that this comparison represents the core of Cassirer’s neo-Kantian interpretation of relativity. Cassirer pointed out that before and after (...) Kant, the history of physics presents significant instances in which the search for formal conditions that the laws of nature must satisfy preceded and made possible the direct search for such laws. In his earlier years, Cassirer seems to have regarded principles like the energy principle, the relativity principle, and the principle of least action as a constitutive but provisional form of a priori, imposing specific limitations on the form of the allowable laws of nature. Only in his later years, by attributing an autonomous status to these statements of principle, did Cassirer attribute a definitive but merely regulative meaning to the a priori. This does not impose specific requirements on natural laws but only a motivation to search for them. (shrink)

From time to time, when I explain to a new acquaintance that I’m a philosopher of science, my interlocutor will nod agreeably and remark that that surely means I’m interested in the ethical status of various kinds of scientific research, the impact that science has had on our values, or the role that the sciences play in contemporary democracies. Although this common response hardly corresponds to what professional philosophers of science have done for the past decades, or even centuries, it (...) is perfectly comprehensible. For there are large questions of the kinds just indicated, questions that deserve to be posed and answered, and an intelligent person might well think that philosophers of science are the people who do the posing and the answering (Kitcher in Science, truth and democracy.

The article contains the replies to the collection of contributions discussing my research on the philosophy of information.

Today, in any mature information society, we live neither online nor offline but on life, that is, we increasingly live in that special space that is both analogue and digital, both online and offline. Imagine someone asking whether the water is fresh or salty in the estuary where the river meets the sea. That someone has not understood the special nature of the place. Our information society is that place. And our technologies are perfectly evolved to take advantage of it, (...) like mangroves growing in brackish water. In the mangrove society, machine-readable data, new forms of agency and interactions are constantly evolving. The consequences of such a radical transformation are many, but one is particularly significant and rich in consequences: how should we design the mangrove society, when it comes to the relationship between the natural and the digital? In this text, I argue that the digital blue is a great ally of the environmental green. The two work best in tandem. And if the world will enjoy a sustainable development for the environment that is also socially preferable for humanity, it will be because the green and the blue will have created a virtuous circle of nature and technology. It can be done. There is just no time to waste. (shrink)

Artificial agents (AAs), particularly but not only those in Cyberspace, extend the class of entities that can be involved in moral situations. For they can be conceived of as moral patients (as entities that can be acted upon for good or evil) and also as moral agents (as entities that can perform actions, again for good or evil). In this paper, we clarify the concept of agent and go on to separate the concerns of morality and responsibility of agents (most (...) interestingly for us, of AAs). We conclude that there is substantial and important scope, particularly in Computer Ethics, for the concept of moral agent not necessarily exhibiting free will, mental states or responsibility. This complements the more traditional approach, common at least since Montaigne and Descartes, which considers whether or not (artificial) agents have mental states, feelings, emotions and so on. By focussing directly on mind-less morality we are able to avoid that question and also many of the concerns of Artificial Intelligence. A vital component in our approach is the Method of Abstraction for analysing the level of abstraction (LoA) at which an agent is considered to act. The LoA is determined by the way in which one chooses to describe, analyse and discuss a system and its context. The Method of Abstraction is explained in terms of an interface or set of features or observables at a given LoA. Agenthood, and in particular moral agenthood, depends on a LoA. Our guidelines for agenthood are: interactivity (response to stimulus by change of state), autonomy (ability to change state without stimulus) and adaptability (ability to change the transition rules by which state is changed) at a given LoA. Morality may be thought of as a threshold defined on the observables in the interface determining the LoA under consideration. An agent is morally good if its actions all respect that threshold; and it is morally evil if some action violates it. That view is particularly informative when the agent constitutes a software or digital system, and the observables are numerical. Finally we review the consequences for Computer Ethics of our approach. In conclusion, this approach facilitates the discussion of the morality of agents not only in Cyberspace but also in the biosphere, where animals can be considered moral agents without their having to display free will, emotions or mental states, and in social contexts, where systems like organizations can play the role of moral agents. The primary cost of this facility is the extension of the class of agents and moral agents to embrace AAs. (shrink)

This article investigates the various ways in which Rudolf Carnap incorporated contemporary epistemological problems concerning the Geisteswissenschaften in Der logische Aufbau der Welt. I argue that Carnap defends a nonreductive incorporation of the Geisteswissenschaften within the unity of science. To this end Carnap aims to solve the problem of individuality, which was the focus of attention for important philosophers of the Geisteswissenschaften such as Wilhelm Dilthey, Heinrich Rickert, and Wilhelm Windelband. At the same time, Carnap argues that his constitutional method, (...) which transforms cultural objects into psychological or physical objects, does not imply a loss of autonomy for the Geisteswissenschaften. Besides this defense of autonomy, Carnap incorporates several central notions of the contemporary theory of the Geisteswissenschaften into his theory of the Aufbau: cultural manifestation, the phenomenology of cultural experience, and the method of Verstehen.

The relativistic revolution led to varieties of neo-Kantianism in which constitutive principles define the object of scientific knowledge in a domain-dependent and historically mutable manner. These principles are a priori insofar as they are necessary premises for the formulation of empirical laws in a given domain, but they lack the self-evidence of Kant’s a priori and they cannot be identified without prior knowledge of the theory they purport to frame. In contrast, the rationalist endeavors of a few masters of theoretical (...) physics have led to comprehensibility conditions that are easily admitted in a given domain and yet suffice to generate the theory of this domain. The purpose of this essay is to compare these two kinds of relativized a priori, to discuss the nature of the comprehensibility conditions, and to demonstrate their effectiveness in a modular conception of physical theories.

Objections to the computational theory of cognition, inspired by twentieth century phenomenology, have tended to fixate on the embodiment and embeddedness of intelligence. In this paper I reconstruct a line of argument that focusses primarily on the abstract nature of scientific models, of which computational models of the brain are one sort. I observe that the critique of scientific abstraction was rather commonplace in the philosophy of the 1920s and 30s and that attention to it aids the reading of The (...) Organism ([1934] 1939) by the neurologist Kurt Goldstein. With this background in place, we see that some brief but spirited criticisms of cybernetics by two later thinkers much influenced by Goldstein, Georges Canguilhem (1963) and Maurice Merleau-Ponty (1961), show continuity with the earlier discussions of abstraction in science.

The historical beginnings of Ernst Cassirer’s philosophy of culture remain unclear. For it is not apparent how his major philosophy of culture and the Philosophy of Symbolic Forms, published in the 1920s, emerged from his earlier epistemological work and Substance and Function from 1910. However, this gap can be filled to a certain extent by the “Disposition” of a “Philosophy of the Symbolic” from 1917 that could be reconstructed from Cassirer’s literary estate and is documented in this contribution. In the (...) preceding “Introduction” an overview of Cassirer’s text is given and some consequences for our general understanding of Cassirer’s project of a philosophy of culture are put up for discussion.
