Negotiation is mainly treated as a process through which counterparts try to satisfy their conflicting interests. This traditional, subjective approach focuses on the interests-based relation between subjects and the resources which are on the bargaining table; negotiation is viewed as a series of joint decisions regarding the relation of each subject to the negotiated resources. In this paper, we will attempt to outline an intersubjective perspective that focuses on the communication-based relation among subjects, a relation that is founded upon communicative (...) rationality mechanisms which are inherent in social activity. Much in contrast to the concept of interests which describe the relationship of each subject alone to the resources, we will use the concept of ?claim-rights? which are properly formed and validated only vis-à-vis negotiating partners and on the basis of the communication that develops among them. We will offer a step-by-step account of the creation of claim-rights and argue that their validation does not necessarily lie in the parties? interests, but in the communication mechanisms that induce consensus and result in mutually acceptable outcomes.

What is a valid measuring instrument? Recent philosophy has attended to logic of justification of measures, such as construct validation, but not to the question of what it means for an instrument to be a valid measure of a construct. A prominent approach grounds validity in the existence of a causal link between the attribute and its detectable manifestations. Some of its proponents claim that, therefore, validity does not depend on pragmatics and research context. In this paper, (...) I cast doubt on the possibility of a context-independent causal account of validity (what I call unconditional validity). I assess several versions, arguing that all of them fail to judge the validity of measuring instruments correctly. Because different research purposes require different properties from measuring instruments, no account of validity succeeds without referring to the specific research purpose that creates the need for measurement in the first place.

Can judging that an agent blamelessly broke a rule lead us to claim, paradoxically, that no rule was broken at all? Surprisingly, it can. Across seven experiments, we document and explain the phenomenon of excuse validation. We found when an agent blamelessly breaks a rule, it significantly distorts people’s description of the agent’s conduct. Roughly half of people deny that a rule was broken. The results suggest that people engage in excuse validation in order to avoid indirectly blaming others (...) for blameless transgressions. Excuse validation has implications for recent debates in normative ethics, epistemology and the philosophy of language. These debates have featured thought experiments perfectly designed to trigger excuse validation, inhibiting progress in these areas. (shrink)

Thomas Hofweber takes the semantic paradoxes to motivate a radical reconceptualization of logical validity, rejecting the idea that an inference rule is valid just in case every instance thereof is necessarily truth-preserving. Rather than this “strict validity”, we should identify validity with “generic validity”, where a rule is generically valid just in case its instances are truth preserving, and where this last sentence is a generic, like “Bears are dangerous”. While sympathetic to Hofweber’s view that strict (...) validity should be replaced by something allowing for exceptions, I argue that this should instead be truth-conduciveness, a matter of a large majority of instances being truth-preserving. The fact that inference rules have uncountably many instances, I argue, can be handled by defining truth-conduciveness as relative to finite sets of instances. Moreover, I argue that Hofweber’s position, while seemingly radical, may be less so under closer scrutiny. For the mere claim that classical rules and unrestricted truth rules are generically valid (or truth-conducive) is not in itself controversial. Also, if there is an answer to the question of which of these are also strictly valid, then the claim that generic validity is the central notion in logic is at most an interest-relative matter, since there is then also a fact of the matter as to which inference rules are (not) strictly valid. If no solution operating with strict validity to the paradoxes can be had, however, then the claim that validity should be identified with a weaker notion is better motivated. I argue that it is reasonable, in view of past failures, to conjecture that no ordinary solution will score high enough relative to standard (uncontroversial) desiderata to merit justified belief. Hence, it is unknowable which solution is correct. I further argue that this is best explained by its being metaphysically indeterminate which solution is correct. If this conjecture is true, then we ought instead to think of validity as allowing exceptions, and then take the “true logic” to be one that takes both the classical rules and the truth rules to be valid, i.e., truth-conducive. This logic scores very high on the desiderata on logics, and is therefore preferable to any logic operating with strict validity. (shrink)

The validity of psychological measurement is crucially connected to a peculiar form of epistemic circularity. This circularity can be a threat when there are no independent ways to assess whether a certain procedure is actually measuring the intended target of measurement. This paper focuses on how Gustav Theodor Fechner addressed the measurement circularity that emerged in his psychophysical research. First, I show that Fechner's approach to the problem of circular measurement involved a core idealizing assumption of a shared human (...) physiology. Second, I assess Fechner's approach to this issue against the backdrop of his own epistemology of measurement and the measurement context of his time. Third, I claim that, from a coherentist and historicallysituated perspective, Fechner's quantification can be regarded as a first successful step of a longer-term quantification process. To conclude, I draw from these insights some general epistemological reflections that are relevant to current quantitative psychology. (shrink)

Havstad (2022) argues that the argument from inductive risk for the claim that non-epistemic values have a legitimate role to play in the internal stages of science is deductively valid. She also defends its premises and thus soundness. This is, as far as we are aware, the best reconstruction of the argument from inductive risk in the existing literature. However, there is a small flaw in this reconstruction of the argument from inductive risk which appears to render the argument (...) invalid. This flaw is superficial, and a small amendment to it rescues the claim of validity. (shrink)

The notion of validity for modal languages could be defined in two slightly different ways. The first is the original definition given by S. Kripke, for which a formula φ of a modal language L is valid if and only if it is true in every actual world of every interpretation of L. The second is the definition that has become standard in most textbook presentations of modal logic, for which a formula φ of L is valid if and (...) only if it is true in every world in every interpretation of L. For simple modal languages, “Kripkean validity” and “Textbook validity” are extensionally equivalent. According to E. Zalta, however, Textbook validity is an “incorrect” definition of validity, because: (i) it is not in full compliance with Tarski’s notion of truth; (ii) in expressively richer languages, enriched by the actuality operator, some obviously true formulas count as valid only if the Kripkean notion is used. The purpose of this paper is to show that (i) and (ii) are not good reasons to favor Kripkean valid- ity over Textbook validity. On the one hand, I will claim that the difference between the two should rather be seen as the result of two different conceptions on how a modal logic should be built from a non-modal basis; on the other, I will show the advantages, for the question at issue, of seeing the actuality operator as belonging to the family of two-dimensional operators. (shrink)

In this paper, I claim that two ways of defining validity for modal languages (“real-world” and “general” validity), corresponding to distinction between a correct and an incorrect way of defining modal valid- ity, correspond instead to two substantive ways of conceiving modal truth. At the same time, I claim that the major logical manifestation of the real- world/general validity distinction in modal propositional languages with the actuality operator should not be taken seriously, but simply as (...) a by-product of the way in which the semantics of such an operator is usually given.

Rejecting the Cut rule has been proposed as a strategy to avoid both the usual semantic paradoxes and the so-called v-Curry paradox. In this paper we consider if a Cut-free theory is capable of accurately representing its own notion of validity. We claim that the standard rules governing the validity predicate are too weak for this purpose and we show that although it is possible to strengthen these rules, the most obvious way of doing so brings with (...) it a serious problem: an internalized version of Cut can be proved for a Curry-like sentence. We also evaluate a number of possible ways of escaping this difficulty. (shrink)

This article critically examines the structure and implications of the argument in ST 1, Q2, A3, associated with Aquinas’ First Way. Our central endeavor is to discern whether a certain disambiguation of point 6 (“There is something that is not moving/changing that moves/changes other things”) can be logically inferred from points 1-5. Through a three-part proof, the article establishes that under specific conditions, it can indeed be inferred. However, this interpretation notably diverges from Aquinas’ intended conclusion and subsequent stronger interpretations (...) of the claim. The paper also engages in discussions surrounding the soundness of the argument, assessing the plausibility of its premises in light of physics and logical analysis. The contribution does not seek to speculate on Aquinas’ understanding or to dismiss his perspective but rather to delineate what follows from his First Way premises, highlighting discrepancies with contemporary views on the nature of existence, particularly the notion of God.

Few of Kant’s distinctions have generated as much puzzlement and criticism as the one he draws in the Prolegomena between judgments of experience, which he describes as objectively and universally valid, and judgments of perception, which he says are merely subjectively valid. Yet the distinction between objective and subjective validity is central to Kant’s account of experience and plays a key role in his Transcendental Deduction of the categories. In this paper, I reject a standard interpretation of the distinction, (...) according to which judgments of perception are merely subjectively valid because they are made without sufficient investigation. In its place, I argue that for Kant, judgments of perception are merely subjectively valid because they merely report sequences of perceptions had by a subject without claiming that what is represented by the perceptions is connected in the objects the perceptions are of. Whereas the interpretation I criticize undercuts Kant’s strategy in the Deduction, I argue, my interpretation illuminates it. (shrink)

What makes a valid argument valid? Generally speaking, in a valid argument, if the premisses are true, then the conclusion must necessarily also be true. But on its own, this doesn’t tell us all that much. What is truth? And what is necessity? In what follows, I consider answers to these questions proposed by the fourteenth century logician John Buridan († ca. 1358). My central claim is that Buridan’s logic is downstream from his metaphysics. Accordingly, I treat his metaphysical (...) discussions as the key to his logic. As has been often noted, Buridan’s metaphysics are radically anti-realist about universals, though I think the depth and scope of his anti-realism has at times been papered over. Buridan constructs his logic on an amazingly spartan ontology, and this accomplishment is overdue for reconsideration. To the foregoing questions: truth is a feature of propositions, and of propositions only—not of proposition-like states of affairs, or anything like that. It is a function of the reference or supposition (suppositio) of their terms, which depends on predication in a propositional context. And necessary truth is grounded in causation: a predication is necessary if it cannot be falsified by any power, natural or supernatural, without ii annihilating what its terms stand for. “Socrates is a human”, for instance, can only be falsified by annihilating Socrates, and so it is a necessary truth. -/- These considerations provide an ample theoretical basis for a thorough examination of Buridan’s modal logic. This is what the thesis culminates with. In the final chapter, I set forth some novel and surprising findings, chief of which is this: Buridan’s modal syntax and semantics are nothing like Kripke’s—and indeed are incompatible with them. This has significant implications not only for modal logic and metaphysics, but for how we think about medieval logic and philosophy more generally. -/- Throughout the thesis, I advocate a methodology of emphasising the differences, rather than the similarities, between past and present thought. Buridan is wildly unlike what we’re used to, and we should let him speak for himself. (shrink)

The problem analysed in this paper is whether we can gain knowledge by using valid inferences, and how we can explain this process from a model-theoretic perspective. According to the paradox of inference (Cohen & Nagel 1936/1998, 173), it is logically impossible for an inference to be both valid and its conclusion to possess novelty with respect to the premises. I argue in this paper that valid inference has an epistemic significance, i.e., it can be used by an agent to (...) enlarge his knowledge, and this significance can be accounted in model-theoretic terms. I will argue first that the paradox is based on an equivocation, namely, it arises because logical containment, i.e., logical implication, is identified with epistemological containment, i.e., the knowledge of the premises entails the knowledge of the conclusion. Second, I will argue that a truth-conditional theory of meaning has the necessary resources to explain the epistemic significance of valid inferences. I will explain this epistemic significance starting from Carnap’s semantic theory of meaning and Tarski’s notion of satisfaction. In this way I will counter (Prawitz 2012b)’s claim that a truth-conditional theory of meaning is not able to account the legitimacy of valid inferences, i.e., their epistemic significance. (shrink)

Neuroscientific claims have a significant impact on traditional philosophy. This essay, focusing on the field of moral neuroscience, discusses how and why philosophy can contribute to neuroscientific progress. First, viewing the interactions between moral neuroscience and moral philosophy, it becomes clear that moral philosophy can and does contribute to moral neuroscience in two ways: as explanandum and as explanans. Next, it is shown that moral philosophy is well suited to contribute to moral neuroscience in both of these two ways in (...) the context of the problem of ecological validity. Philosophy can play the role of an agent for ecological validity, since traditional philosophy shapes and reflects part of our social reality. Finally, based on these arguments, I tentatively sketch how a Kantian account of moral incentive can play this role. (shrink)

This article discusses an anomaly in the English law of reproductive liability: that is, an inconsistency between the law’s approach to wrongful life claims and its approach to cases of negligent selection of gametes or embryos in infertility treatments (the selection cases). The article begins with an account of the legal position, which brings into view the relevant inconsistency: while the law treats wrongful life claims as non- actionable, it recognises a cause of action in the selection cases, although the (...) selection cases bear a relevant resemblance to wrongful life claims. The article then considers arguments that may be invoked in an attempt to reconcile the above two strands of the law. Three of these counterarguments consist in attempts to distinguish the selection cases from wrongful life claims. It is argued that these attempts fail to reveal a valid basis for treating these situations differently. A fourth possible counterargument levels against the present analysis a charge of reductio ad absurdum. It is shown that this argument suffers from a fundamental flaw caused by confusion between different senses of the term “identity”. Finally, the article discusses possible changes to the legal position that could rectify the problem. It argues that one of these changes, which focuses on legal redress for violation of personal autonomy, is particularly apt to resolve the problem at hand, but also highlights the need for further inquiry into the broader implications of introducing this form of redress into the law of torts.

Against interpretations of Kant that would assimilate the universality claim in judgments of taste either to moral demands or to theoretical assertions, I argue that it is for Kant a normative requirement shared with ordinary empirical judgments. This raises the question of why the universal agreement required by a judgment of taste should consist in the sharing of a feeling, rather than simply in the sharing of a thought. Kant’s answer is that in a judgment of taste, a feeling (...) assumes the role of predicate. Such a solution presents a problem as serious as the one it purports to solve. (shrink)

The transformational pace of modern education, healthcare, business management systems, etc., requires new approaches for prompt and reliable personality assessment. Phenotypology is one of such theories and it claims of the discovered interconnections of a person’s psychological and psychophysical characteristics on the basis of individual features of his/her phenotype. The article aim is to present some validation results for the Phenotypology hypotheses as a possible tool for personality assessment. In order to verify connections between phenotypic treats and individual behavior, we (...) conducted the study when respondents were differentiated according to some anthropometric (facial) peculiarities and characterological features. The results were quantified and analyzed using the mathematical-statistical linear regression. The research output contains the rationale for the conclusion that there are no statistically significant correlations between some phenotypic body features and such individual psychological characteristics as aggressiveness, impetuosity, pedantry, passivity, etc. In particular, the validity of using of appropriate phenotypologic representations to predict the examined character traits was studied. The obtained results disproved the possibility to use directly the phenotypic approach for reliable characterological profiling. Though, the study outcome is tentative due to some limitations on generality. It is necessary to continue verification of the Phenotypology hypotheses with a broader experimental sample with the inclusion of various ethnic and racial groups’ representatives. However, until then, based on actual findings, the practical application of the Phenotypology statements is doubtful, at least for the purposes of character diagnosis and personality assessment.

The usage of Randomised Evaluations(REs) in social inquiry has been recent and responses to them have been wide ranging.RE seek to make predictions on the impact of an intervention, when it is attempted in a new situation. REs work by first determining the impact of the intervention. Subsequently, for the new situation it is expected that the impact would be similar. -/- The problem of induction poses one of the most serious challenges to the epistemological status of RE claims as (...) the value of REs themselve stem from their predictive validity. If the problem of induction is not solved or evaded then belief in projections based on REs is undermined. -/- In this paper, I argue that the unique methodology of REs used in Social Sciences allows itself to evade the problem the successfully, warranting belief that future interventions would have similar impact.

Metaphysics relies on the presupposition of the non-being of the world: since the world has once not existed it is necessary to postulate a cause for its existence, i.e. an extrinsic principle to explain the absolute beginning of the causal series of all things that constitute the world. After the critique of theologizing metaphysics by authors like Kant, Hegel and Nietzsche, the notion of an absolute beginning still persists though in a field in which it often goes as such unnoticed, (...) while it factually enjoys wide acceptance, namely in epistemology. It sounds as a truism that knowledge begins: personal inexistence (birth-death cycle) and the phenomenon of unconsciousness (sleep-wake cycle) seem to endorse the obviousness of that statement. Now, to link the beginning of the phenomenal series of subjective acts of knowledge with the existence of an external world that causes the specific content of our temporary cognitive acts relies, however, on two presuppositions, namely on the thesis of a complete non-being or nothingness of knowledge and, intrinsically related to this first presupposition, on the thesis of an absolute beginning of cognitive activity. If knowledge begins from its own nothingness, there must be a cause that is external to the totality of acts of knowledge, a cause that it doesn´t belong to the series of cognitive acts and, therefore, that it is not caused by any of them: this uncaused cause of contentful knowledge is supposed to be the real world external to the knowing subject. In my paper I make explicit the relation between realist-empiricist approachs to epistemology and the double presupposition of the nothingness and absolute beginning of knowledge, I explain the difficulties implied by these two presuppositions and, finally, I propose as a plausible solution to those difficulties some key theoretical claims of absolute idealism.

Scientific realists argue that a good track record of multi-agent, and multiple method, validation of empirical claims is itself evidence that those claims, at least partially and approximately, reflect ways nature actually is independent of the ways we conceptualize it. Constructivists contend that successes in validating empirical claims only suffice to establish that our ways of modelling the world, our “constructions,” are useful and adequate for beings like us. This essay presents a thought experiment in which beings like us intersubjectively (...) validate claims about properties of particular things in nature under conditions in which those beings have profoundly different personal phenomenological experiences of those properties. I submit that the thought experiment scenario parallels our actual situation, and argue that this shows that successes in intersubjectively validating empirical claims are indeed enough to claim victory for the realist. More specifically, I champion a variation of realism that marries Ronald Giere’s brand of ‘perspectival realism’ with Philip Kitcher’s ‘real realism,’ and posits that causal relations between ourselves and properties instantiated in nature ground our references to the relevant properties even though our conceptions of them are perspective relative.

Werner Heisenberg made an important – and as yet insufficiently researched – contribution to the transformation of the modern conception of science. This transformation involved a reassessment of the status of scientific knowledge from certain to merely hypothetical – an assessment that is widely recognized today. I examine Heisenberg’s contribution in particular by taking his conception of “closed theories” as an example according to which the established physical theories have no universal and exclusive, but only a restricted validity. Firstly, (...) I characterize the historical process of hypothetization of claims to validity. Then, secondly, I reconstruct Heisenberg’s conception, as far as it can be derived from his popular writings, relating it to the process of hypothetization. Finally, I touch on the history of its reception and compare it with conceptions of science that emphasize the significance of the hypothetical for the modern theories of natural sciences. Compared to these conceptions, Heisenberg’s contribution turns out to be rather independent. (shrink)

With his influence on the development of physiology, physics and geometry, Hermann von Helmholtz – like few scientists of the second half of the 19th century – is representative of the research in natural science in Germany. The development of his understanding of science is not less representative. Until the late sixties, he emphatically claimed the truth of science; later on, he began to see the conditions for the validity of scientific knowledge in relative terms, and this can, in (...) summary, be referred to as hypothesizing. Already in the past century, HeImholtz made first approaches to an understanding of science, which were incompatible with his own former position and which pointed to the modern age to an astonishingly large extent. A comparison with Karl R. Popper's logic of research will illustrate how closely he nevertheless approached modern understanding of science. In Popper's logic of research, hypothesizing of scientific knowledge is definitely much more advanced than in Helmholtz's theory of science. What begins vaguely to emerge with Helmholtz has already become an explicitly formulated programme with Popper. Although HeImholtz and Popper are not on a direct line of epistemological development and Popper refers to HeImholtz only rarely and casually, there are in fact surprising points of contact which have not been taken notice of so far and which appear above all if one looks at Helmholtz's understanding of science against the background of Popper's logic of research.

Important decisions that impact humans lives, livelihoods, and the natural environment are increasingly being automated. Delegating tasks to so-called automated decision-making systems can improve efficiency and enable new solutions. However, these benefits are coupled with ethical challenges. For example, ADMS may produce discriminatory outcomes, violate individual privacy, and undermine human self-determination. New governance mechanisms are thus needed that help organisations design and deploy ADMS in ways that are ethical, while enabling society to reap the full economic and social benefits of (...) automation. In this article, we consider the feasibility and efficacy of ethics-based auditing as a governance mechanism that allows organisations to validate claims made about their ADMS. Building on previous work, we define EBA as a structured process whereby an entity’s present or past behaviour is assessed for consistency with relevant principles or norms. We then offer three contributions to the existing literature. First, we provide a theoretical explanation of how EBA can contribute to good governance by promoting procedural regularity and transparency. Second, we propose seven criteria for how to design and implement EBA procedures successfully. Third, we identify and discuss the conceptual, technical, social, economic, organisational, and institutional constraints associated with EBA. We conclude that EBA should be considered an integral component of multifaced approaches to managing the ethical risks posed by ADMS. (shrink)

Abstract: The article aims to sharpen the neo-republican contribution to international political thought by challenging Pettit’s view that only representative states may raise a valid claim to non-domination in their external relations. The argument proceeds in two steps: First I show that, conceptually speaking, the domination of states, whether representative or not, implies dominating the collective people at least in its fundamental, constitutive power. Secondly, the domination of states – and thus of their peoples – cannot be justified normatively (...) in the name of promoting individual non-domination because such a compensatory rationale misconceives the notion of domination in terms of a discrete exercise of power instead of as an ongoing power relation. This speaks in favour of a more inclusive law of peoples than Pettit (just as his liberal counterpart Rawls) envisages: In order to accommodate the claim of collective peoples to non-domination it has to recognize every state as a member of the international order.

Large Language Models (LLMs) are generative AI systems capable of producing original texts based on inputs about topic and style provided in the form of prompts or questions. The introduction of the outputs of these systems into human discursive practices poses unprecedented moral and political questions. The article articulates an analysis of the moral status of these systems and their interactions with human interlocutors based on the Habermasian theory of communicative action. The analysis explores, among other things, Habermas's inquiries into (...) the analogy between human minds and computers, and into the status of atypical participants in the linguistic community such as genetically modified subjects and animals. Major conclusions are the LLMs seem to qualify as authors that originally participate in discursive practices but do display only a structurally derivative form of communicative competence and fail to meet the status of communicative agents. In this sense, while the contribution of AI writing systems in public discourse and deliberation can support the process of mutual understanding within the community of speakers, the human actors involved in the development, use, and diffusion of these systems share a collective responsibility for the disclosure of AI authorship and verification and adjudication of validity claims.

This paper defends the idea that Cassirer's methodology is idealistic in regard to validity claims and the structuralist views he holds and at the same time empiric in regard to the facts and genealogy of culture. This perspective is best to be unfolded along Cassirer's model of representation. The author does so by showing that Cassirer's triad of symbolic articulation (expressive, presentational, significative) and the triad of symbolic development (mimetic, analogical, symbolic) form a coherent and exhaustive theory of symbolic (...) formation. In order to defend this view, two main objections from the secondary literature against the consistency of this essential theory piece of The Philosophy of Symbolic Forms have to be rejected.

We identify the ethics of reparations policies as its own distinct field of inquiry, and consider several neglected ethical issues that arise in the process of devising reparations programmes.

The problem of exclusion refers to individuals with seemingly valid claims being turned away. Finally, the problem of inclusion has to do with including (...) would-be claimants who are not mobilized in making a reparations demand, as well as with reconciling competing reparations demands.

This article provides a critical assessment of Habermas’s recent work on religion and its role in the public sphere by comparing it to Kant’s phi-losophy of religion on the one hand and that of Kierkegaard on the other.

This has (...) implications not just for the conception of religion but also for the very roles of communication, validity, rationality, and philosophy. (shrink)

This paper deals with the question whether some morally normative content is grounded in the dialogical practice that both Apel and Habermas call argumentative discourse, and if so how to demonstrate that it is so grounded. Apel (unlike Habermas) claims that discourse has rationally necessary conceptual presuppositions; that morally normative content is part of such presuppositions; and that this can be ascertained in transcendendal reflection, i.e. by a kind of transcendental argument. I argue that these claims can be charitably interpreted (...) but require clarifications of their key concepts, i.e. “discourse”, “validity claims”, “performative self-contradiction”, and “community of communication”. I argue that discourse as a practice of reason-sensitive agents who are communicatively connected via argumentation can be explained by its normatively constitutive aim, namely fixing the true values of our reasons; that the primary level of validity claims are claims concerning good reasons; that performative self-contradictions are pragmatic-cum-logical inconsistencies that we can know apriori to be incompatible with discourse’s constitutive aim; and finally, that competent discourse participants can know apriori that they would be performatively inconsistent if they flouted a moral kernel that is intrinsic in discourse.

This paper explores Dilthey’s radical transformation of epistemology and the human sciences through his projects of a critique of historically embodied reason and his hermeneutics of historically mediated life. Answering criticisms that Dilthey overly depends on epistemology, I show how for Dilthey neither philosophy nor the human sciences should be reduced to their theoretical, epistemological, or cognitive dimensions. Dilthey approaches both immediate knowing (Wissen) and theoretical knowledge (Erkenntnis) in the context of a hermeneutical phenomenology of historical life. Knowing is not (...) an isolated activity but an interpretive and self-interpretive practice oriented by situated reflexive awareness (Innewerden) and self-reflection (Selbstbesinnung). As embedded in an historical relational context, knowing does not only consist of epistemic validity claims about representational contents but is fundamentally practical, involving all of human existence. Empirically informed Besinnung, with its double reference to sense as meaning and bodily awareness, orients Dilthey’s inquiry rather than the “irrationalism” of immediate intuition or the “rationalism” of abstract epistemological reasoning.

Do claims of taste function as validity claims? Our ordinary use of aesthetic notions suggests as much. When I assert that Rodin’s Camille Claudel is ‘beautiful’ I mean my claim to be, in a sense, correct. I expect others to concur and if they do not I think that they are mistaken. But am I justified in attributing an error to the judgment of someone who, unlike me, does not find Rodin’s Camille Claudel beautiful? Not obviously. For it (...) looks, on the other hand, that my assertion “The sculpture of Camille Claudel is beautiful” is not an assertion about a property of that sculpture, not, that is, about a feature of the world which exists for others as well as for me. Quite the opposite, I seem to base my claim on a subjective response, on a certain feeling of mine. I maintain that the sculpture of Camille Claudel is ‘beautiful’ because it produces a particular effect upon me, namely it pleases me aesthetically. But how can the feeling of pleasure, being a subjective response on my part, serve as a normative ground for a claim? (shrink)

The papers of this special issue are the outcome of a two-­‐day conference entitled “The Second-­‐Person Standpoint in Law and Morality,” that took place at the University of Vienna in March 2013 and was organized by the ERC Advanced Research Grant “Distortions of Normativity.” -/- The aim of the conference was to explore and discuss Stephen Darwall’s innovative and influential second-­‐personal account of foundational moral concepts such as „obligation“, „responsibility“, and „rights“, as developed in his book The Second-­‐Person Standpoint: Morality, (...) Respect, and Accountability (Harvard University Press 2006) and further elaborated in Morality, Authority and Law: Essays in Second-­‐Personal Ethics I and Honor, History, and Relationships: Essays in Second-­‐Personal Ethics II (both Oxford University Press 2013). -/- With the second-­‐person standpoint Darwall refers to the unique conceptual normative space that practical deliberators and agents occupy when they address claims and demands to one another (and to themselves). The very first sentence of Darwall’s examination of the second-­‐personal conceptual paradigm summarizes the gist of the argument succinctly when he claims that “the second-­‐person standpoint [is] the perspective that you and I take up when we make and acknowledge claims on one another’s conduct and will.” (Darwall 2006, 3) The Second-­‐Person Standpoint reminds us that this perspective has been ignored for much too long and that it better take centre stage in any philosophical analysis of moral phenomena, in order to yield a satisfying account of morality as a social institution. The negative part of Darwall’s strategy is to show that neither a purely first-­‐personal approach (represented by Kant and contemporary Kantians), nor a third-­‐personal state-­‐of-­‐affairs-­‐perspective (represented by most varieties of contemporary consequentialism) are capable of accounting for the categorical bindingness characteristic of moral obligation. The latter feat can only be accomplished, and this is the positive part of Darwall’s argument, when those second-­‐ personal normative “felicity conditions” and conceptual presuppositions are acknowledged and spelled out that are already presupposed in every instance of issuing (putatively valid) claims and demands. It is especially second-­‐personal competence and second-­‐personal authority that are the bedrock of these normative conceptual presuppositions, without which engaging in any meaningful address would be impossible. Kantians and utilitarians alike have neglected this critical dimension of the normative landscape. -/- In addition to working out an original conception of moral obligation, the first eight chapters of The Second-­‐Person Standpoint articulate this fundamental insight with respect to a variety of traditional projects in ethical theory such as developing accounts of moral responsibility, rights, dignity, and autonomy. In this context, special emphasis is to be awarded, on the one hand, to Darwall’s refreshing second-­‐personal interpretation of Strawson’s influential account of reactive attitudes and moral responsibility and, on the other, to his historically well-­‐informed reconstruction of Samuel Pufendorf’s often neglected version of an enlightened theistic voluntarism concerning moral authority. Darwall dedicates the second part of The Second-­‐Person Standpoint to the urgent question: how should one respond to the sceptical challenge that expresses utter indifference to the second-­‐person standpoint, including all its multifarious normative presuppositions and implications? What commits us to all this? It is at this point that Darwall, firstly, refines his criticisms of the Kantian, first-­‐personal, paradigm of normativity and emphasizes that only if one already incorporates the second-­‐personal conceptual apparatus into a Kantian analysis of moral obligation is the latter going to yield a convincing account. Secondly, and this certainly is one of the highlights of Darwall’s theory, the Second-­‐Person Standpoint employs themes from Fichte’s philosophy of right in order to strengthen the case for the inescapability of taking up the second-­‐person standpoint of moral obligation. In his contribution for this special issue Darwall further develops his diagnosis that Fichte’s thought offers in many respects a more promising, since more second-­‐personal, foundation of morality than, for example, Kant’s. -/- By now, the impact of Darwall’s second-­‐person standpoint theory has far transcended the confines of contemporary debates on moral obligation. Darwall has put to use the second-­‐personal apparatus to critical engagements with Joseph Raz’s theory of legal authority and Derek Parfit’s convergence arguments for his recent Triple Theory of moral wrongness. The constant theme that unifies all these diverse applications remains the one so impressively presented in The Second-­‐Person Standpoint: without paying attention to the “interdefinable” and “irreducible” circle of (four) foundational second-­‐ personal concepts (valid demand, practical authority, second-­‐personal reason, and accountability), neither superior epistemic status (Raz) nor the identification of optimific states of affairs (Parfit) are potent enough sources to generate anything close to the authority relationships that underlie the idea involved in obligating ourselves and one another. Given all of the above, it comes as no surprise that Darwall reserves his strongest sympathies for a specific ethical theory, namely contractualism. Our commitment to equal basic second-­‐personal authority, that Darwall arrives at through his Fichtean rectification of the Kantian project, leads him to the endorsement of a contractualist paradigm in the spirit of broadly Rawls and Scanlon. -/- .

Husserl’s phenomenology opens itself with a critique of positive sciences. Husserl problematizes the hardcore presupposition of positivism that the world is a definite sort of an existential totality of objects and thus it is exhaustible with empirical data and deductive-conceptual abstraction on the basis of causalspatio-temoprality. Criticizing the wholesome reduction of nature into a physical reality and the instrumentalizing of theoretical reason, he proposes transcendental phenomenology, as an ideal form of science. Self-entitled as the genuine science, the science of origin, (...) the science of all sciences, etc., it concerns itself with the matter of validity. Claiming that validating objectivity as such and the meaning of scientific objectification is something of which onlyphenomenological reflection on pure consciousness is capable and that the positivistic objectivity is and must be founded on transcendental subjectivity, Husserl radically idealistically revised the whole positivistic concept of evidence and givenness of a fact and substituted it with the phenomenological notion of apriori self-evidence and originary givenness of primordial intentional consciousness. Nevertheless, it is noticed that the absolute universal validity of positivistic objectivity was never rejected or questioned; objectivity is still in and of itself an absolute criterion of scientificity in Husserl. This paper will argue that the idealistic turn toward subjectivity takes place through factualization of transcendentality and this, by bestowing apriori apodicticity with facticity, even enhances more the supreme epistemological function of positivity. It will discuss such positivistic drive, directly bequeathed from the very cultural ethos at which phenomenological criticism targeted, as an important locomotive for Husserl’s program and point out an antinomical consequence with which it is to be faced as a consequence.

I discuss Prawitz’s claim that a non-reliabilist answer to the question “What is a proof?” compels us to reject the standard Bolzano-Tarski account of validity, andto account for the meaning of a sentence in broadly verificationist terms. I sketch what I take to be a possible way of resisting Prawitz’s claim---one that concedes the anti-reliabilist assumption from which Prawitz’s argument proceeds.

In the following paper I will examine the possibility for a rational foundation of morals, rational in the sense that to ground a moral statement on reason amounts to being able to convince an unmotivated agent to conform to a moral rule - that is to say, to “rationally motivate” him (as Habermas would have said) to act in ways for which he or she had no previous reason to act. We will scrutinize the “internalist’s” objection (in Williams’ definition) to (...) such a claim and confront it with a, however, obvious fact: our need to convince or, at least, to influence agents to act according to moral judgements that entail strong validity claims. Therefore we need to find a better ground for our moral norms than that provided by a narrow concept of practical reason, which ultimately offers the basis for the internalist’s intuitions. Classical philosophers believed that to have a “right” sense meant also to think accordingly, that there was no intelligence without a social or moral side and that a person who lacked moral sense was not, at the same time, very intelligent. This contradicts some deep Humean intuitions, and in any case requires a more complex concept of practical reason than the one we normally encounter in internalist moral philosophers. In the following pages, I would like to reflect on this kind of social reason, or intelligence, or moral rationality, in an attempt to couple, in a coherent vision of moral sense within the framework of practical reason, intuitions that appear in Kant and Adam Smith with empirical research about what the lack of moral sense could mean.

The claim defended in the paper is that the mechanistic account of explanation can easily embrace idealization in big-scale brain simulations, and that only causally relevant detail should be present in explanatory models. The claim is illustrated with two methodologically different models: Blue Brain, used for particular simulations of the cortical column in hybrid models, and Eliasmith’s SPAUN model that is both biologically realistic and able to explain eight different tasks. By drawing on the mechanistic theory of computational (...) explanation, I argue that large-scale simulations require that the explanandum phenomenon is identified; otherwise, the explanatory value of such explanations is difficult to establish, and testing the model empirically by comparing its behavior with the explanandum remains practically impossible. The completeness of the explanation, and hence of the explanatory value of the explanatory model, is to be assessed vis-à-vis the explanandum phenomenon, which is not to be conflated with raw observational data and may be idealized. I argue that idealizations, which include building models of a single phenomenon displayed by multi-functional mechanisms, lumping together multiple factors in a single causal variable, simplifying the causal structure of the mechanisms, and multi-model integration, are indispensable for complex systems such as brains; otherwise, the model may be as complex as the explanandum phenomenon, which would make it prone to so-called Bonini paradox. I conclude by enumerating dimensions of empirical validation of explanatory models according to new mechanism, which are given in a form of a “checklist” for a modeler. (shrink)

The last two decades have seen a rising interest in (a) the notion of a scientific phenomenon as distinct from theories and data, and (b) the intricacies of experimentally producing and stabilizing phenomena. This paper develops an analysis of the stabilization of phenomena that integrates two aspects that have largely been treated separately in the literature: one concerns the skills required for empirical work; the other concerns the strategies by which claims about phenomena are validated. I argue that in order (...) to make sense of the process of stabilization, we need to distinguish between two types of phenomena: phenomena as patterns in the data ( surface regularities ) and phenomena as underlying (or hidden ) regularities. I show that the epistemic relationships that data bear to each of these types of phenomena are different: Data patterns are instantiated by individual data, whereas underlying regularities are indicated by individual data, insofar as they instantiate a data pattern. Drawing on an example from memory research, I argue that neither of these two kinds of phenomenon can be stabilized in isolation. I conclude that what is stabilized when phenomena are stabilized is the fit between surface regularities and hidden regularities. (shrink)

Current intellectual calls for more socially minded governance often resort to the authority of the experimental and behavioral economists who have provided uncontroversial evidence for the generalized existence of a Homo socialis. For a qualitative social researcher, the narrative of a “discovery” makes little sense. This article provides a more meaningful account of the experimental rationale of prosocial preferences research, interrogating, from a “decolonial” theoretical perspective, the epistemic and normative implications of a method that persuasively claims to have challenged the (...) intellectual imperialism of Homo economicus. Just as the colonial discourse that speaks of the “discovery” of America has shaped the global Eurocentric mentality that splits the world into hierarchical binaries, the academic discourse that speaks of the “discovery” of Homo socialis could reinforce a behavioral range that reduces the interpretation of non-prosocial choices to a binary spectrum still metrologically organized around Homo economicus. The danger is that Southern subjects do not always have the privilege of feeling prosocial and could be penalized for their disadvantage within a socially minded mode of governance. To address this danger, the article argues, experimental social scientists need to become qualitatively attuned to the methodological question of “range validity” beyond the traditional one of “external validity.”.

This special issue collects together nine new essays on logical consequence :the relation obtaining between the premises and the conclusion of a logically valid argument. The present paper is a partial, and opinionated,introduction to the contemporary debate on the topic. We focus on two influential accounts of consequence, the model-theoretic and the proof-theoretic, and on the seeming platitude that valid arguments necessarilypreserve truth. We briefly discuss the main objections these accounts face, as well as Hartry Field’s contention that such objections (...) show consequenceto be a primitive, indefinable notion, and that we must reject the claim that valid arguments necessarily preserve truth. We suggest that the accountsin question have the resources to meet the objections standardly thought to herald their demise and make two main claims: (i) that consequence, as opposed to logical consequence, is the epistemologically significant relation philosophers should be mainly interested in; and (ii) that consequence is a paradoxical notion if truth is.

In this paper, I discuss the debate on Kant and nonconceptual content. Inspired by Kant’s account of the intimate relation between intuition and concepts, McDowell (1996) has forcefully argued that the relation between sensible content and concepts is such that sensible content does not severally contribute to cognition but always only in conjunction with concepts. This view is known as conceptualism. Recently, Kantians Robert Hanna and Lucy Allais, among others, have brought against this view the charge that it neglects the (...) possibility of the existence of essentially nonconceptual content that is not conceptualised or subject to conceptualisation. Their critique of McDowell amounts to nonconceptualism. However, both views, conceptualist and nonconceptualist, share the assumption that intuition is synthesised content in Kant’s sense. My interest is not in the validity of the philosophical positions of conceptualism or nonconceptualism per se. I am particularly interested in the extent to which the views that McDowell and Hanna and Allais respectively advance are true to Kant, or can validly be seen as Kantian positions. I argue that although McDowell is right that intuition is only epistemically relevant in conjunction with concepts, Hanna and Allais are right with regard to the existence of essentially nonconceptual content (intuitions) independently of the functions of the understanding, but that they are wrong with regard to non-conceptualised intuition being synthesised content in Kant’s sense. Kantian conceptualists (Bowman 2011; Griffith 2012; Gomes 2014) have responded to the recent nonconceptualist offensive, with reference to A89ff./B122ff. (§13)—which, confusingly, the nonconceptualists also cite as evidence for their contrary reading—by arguing that the nonconceptualist view conflicts with the central goal of the Transcendental Deduction, namely, to argue that all intuitions are subject to the categories. I contend that the conceptualist reading of A89ff./B122ff. is unfounded, but also that the nonconceptualists are wrong to believe that intuitions as such refer strictly to objects independently of the functions of the understanding, and that they are mistaken about the relation between figurative synthesis and intellectual synthesis. I argue that Kant is a conceptualist, albeit not in the sense that standard conceptualists assume. Perceptual knowledge is always judgemental, though without this resulting in the standard conceptualist claim that, necessarily, all intuitions or all perceptions per se stand under the categories (strong conceptualism). I endorse the nonconceptualist view that, for Kant, perception per se, i.e. any mere or ‘blind’ intuition of objects (i.e. objects as indeterminate appearances) short of perceptual knowledge, does not necessarily stand under the categories. Perception is not yet perceptual knowledge. In this context, I point out the common failure in the literature on the Transcendental Deduction, both of the conceptualist and nonconceptualist stripe, to take account of the modal nature of Kant’s argument for the relation between intuition and concept insofar as cognition should arise from it.

I claim that ‘cause and effect’ only appears to involve distinct existences insofar as we can’t adequately understand the relationship, or insofar as we are determined to look at the matters of fact involved from a logically deductive point of view. Since ‘cause and effect’ often represents the first stab at understanding what happens in a situation, this means it will often appear to involve distinct existences, and since logical deduction is the acme of what it is to perform (...) adequate reasoning, for philosophers, this re-enforces this appearance, to philosophers. In contrast I claim we can try to avoid drawing conclusions beyond objects or factors in a situation, by comparing them as we attempt to trace them about. In so far as we succeed, since we have not had to go beyond the continued existence of those factors, they themselves must appear sufficient to produce that part of the situations they continue into and so construct. I also claim if somethings appear themselves sufficient to bring something about this is inconsistent with the claim it depends on something else e.g. human understanding, or language. Two cases; 1) If we assume this object has, or continues to have some properties e.g. weight, then on this basis we can validly deduce such & such consequences. 2) The continued existence of this object with weight would (or is) itself be sufficient to bring about…. The first makes what we are up to depend on our mode of reasoning, or what we recognize as ‘our way and principles of reasoning’. The second discovers the situation to be autonomous. (shrink)

Mit seinem Einfluß auf die Entwicklung der Physiologie, Physik und Geometrie ist Hermann von Helmholtz wie kaum ein anderer Wissenschaftler der zweiten Hälfte des 19. Jahrhunderts repräsentativ für die Naturforschung in Deutschland. Nicht weniger repräsentativ nimmt sich die Entwicklung seiner Wissenschaftsauffassung aus. Während er bis in die späten 60er Jahre einen emphatischen Wahrheitsanspruch der Wissenschaft vertrat, begann er in der nachfolgenden Zeit, die Geltungsbedingungen der wissenschaftlichen Erkenntnis einer Relativierung zu unterwerfen, die zusammenfassend als Hypothetisierung bezeichnet werden kann. Helmholtz entwickelte damit (...) schon im vergangenen Jahrhundert Ansätze einer Wissenschaftsauffassung , die in erstaunlichem Umfang in die Richtung der Moderne weisen. Wie nah er späteren Wissenschaftsauffassungen bereits gekommen ist, kann ein Vergleich mit Karl R. Poppers Forschungslogik illustrieren. In seiner Forschungslogik ist die Hypothetisierung der wissenschaftlichen Erkenntnis entschieden weiter vorangeschritten als in Heimholtz' Wissenschaftstheorie. Was sich bei Helmholtz erst vage abzuzeichnen beginnt, ist bei ihm bereits explizit formuliertes Programm geworden. Obwohl HeImholtz und Popper in keiner direkten wissenschaftstheoretischen Entwicklungslinie stehen und Popper sich in seinen Schriften auch nur sehr selten und beiläufig auf Helmholtz bezieht, finden sich dennoch überraschende und bisher nicht beachtete Berührungspunkte, die insbesondere dann hervortreten, wenn man Heimholtz' Wissenschaftsauffassung vor dem Hintergrund von Poppers Forschungslogik betrachtet.

Is there an approach to human rights that justifies rights-allocating moral-political principles as principles that are equally acceptable by everyone to whom they apply, while grounding them in categorical, reasonably non-rejectable foundations? The paper examines Rainer Forst’s constructivist attempt to provide such an approach. I argue that his view, far from providing an alternative to “ethical” approaches, depends for its own reasonableness on a reasonably contestable conception of the good, namely, the good of constitutive discursive standing. This suggests a way (...) in which constructivism about human rights might be able to coherently and plausibly negotiate the tension between the scope, the depth and the strength of discursive inclusion: the justification of rights-allocating moral-political principles needs to be premised on an “ethical”, perfectionist defense of the good of constitutive discursive standing.

Die Entwicklung von HeImholtz' Mechanismus ist durch einen Wandel im Geltungsanspruch gekennzeichnet und läßt sich in einer noch sehr groben Übersicht in zwei Perioden einteilen. Auf die erste Periode bis etwa zum Ende der 60er Jahre werde ich im ersten Teil meines Beitrages eingehen. Hier rekonstruiere ich umrißhaft die empiristische Begründung, die Helmholtz für den Wahrheitsanspruch seiner Naturauffassung gegeben hat. Im zweiten Teil werde ich dann die wichtigsten Merkmale der im Verlauf der 70er Jahre hervortretenden Hypothetisierungstendenz charakterisieren. Abschliessend will ich (...) in einem dritten Teil zeigen, wie Helmholtz auf der Grundlage seines gewandelten Wissenschaftsverständnisses das Programm einer mechanistischen Naturerklärung mit großem wirkungsgeschichtlichen Einfluß weiter verfolgt hat.

Inwieweit vermag sich der ehemalige explanative Erfolg nicht mehr anerkannter Theorien auf die Geltung derjenigen Teilaussagen, die Nachfolgetheorien übernommen haben, zu stützen? Zur Klärung dieser Fragestellung können die Ergebnisse von Machs Untersuchung zur mechanistischen Auffassung des Energieerhaltungssatzes herangezogen werden. Indem er sich in seiner Kritik an den ontologischen Annahmen des Mechanismus auf die Wissenschaftsgeschichte beruft, steht er einer heutigen realismuskritischen Argumentation nahe. Andererseits mißt er den hypothesenfreien Theoriebestandteilen einen Geltungscharakter zu, der in seinem Wahrheitsanspruch durchaus mit einer heutigen realistischen Behauptung (...) theorieübergreifender Bestände der wissenschaftlichen Erkenntnis vergleichbar ist. Daß Mach mit einer quer zur gegenwärtigen Terminologie liegenden Analyse einen Beitrag zur Entschärfung gegenwärtiger Kontroversen leistet, läßt eine erneute Vergegenwärtigung der Schrift von 1872 und den sich daran anschließenden Überlegungen Machs lohnenswert erscheinen.

Troeltschs Auseinandersetzung mit naturwissenschaftlichen Weltbildern in "Der Historismus und seine Probleme" bietet grundlegende, noch heute aktuelle Einsichten in die Erkenntnisbedingungen der Naturwissenschaften. Der Begriff des Naturalismus erhält in diesem Zusammenhang eine ähnliche Mehrdeutigkeit wie der Begriff des Historismus (1). Troeltschs Position zu naturwissenschaftlichen Erkenntnissen und ihren Verallgemeinerungen zu Weltbildern findet einen öffentlichen Ausdruck in seiner ambivalenten Haltung gegenüber der nach dem Ersten Weltkrieg aufkommenden Naturwissenschaftskritik. Man kann vermuten, daß diese lebensphilosophisch ausgerichtete Nachkriegsströmung auf die Herausbildung des heutigen Begriffs von Naturwissenschaft (...) beträchtlichen Einfluß ausgeübt hat. Ohne sich das Programm der wiedererstarkten Lebensphilosophie zu eigen zu machen, teilt Troeltsch ihre entschiedene Ablehnung naturwissenschaftlich orientierter Generalisierungsbemühungen (2). In den letzten beiden Teilen möchte ich exemplarisch zeigen, daß sich die soweit rekonstruierte wissenschaftstheoretische Position auch auf Troeltschs frühere Analysen stützen kann. Eine 1901 verfaßte Besprechung von Haeckels Buch „Die Welträthsel“, dem herausragenden Beispiel öffentlichkeitswirksamer Sinnstiftung aus den biologischen Wissenschaften, illustriert seine schon früh differenzierte Geltungskritik naturwissenschaftlicher Weltbilder (3). Schließlich können die im Spätwerk enthaltenen Einsichten in den größeren Kontext seiner schon zu Anfang des Jahrhunderts erschienenen Analysen des Modernisierungsprozesses, in denen er den Naturwissenschaften eine zentrale Rolle zumißt, eingeordnet werden (4).

Werner Heisenberg hat einen wichtigen, noch nicht hinreichend untersuchten Beitrag zum Wandel des neuzeitlichen Wissenschaftsverständnisses geleistet. Der Wandel führte von der Charakterisierung des wissenschaftlichen Wissens als sichere Erkenntnis zu seiner - heute weithin anerkannten - Charakterisierung als bloß hypothetische Erkenntnis. Anfänge dieses Wandlungsprozesses lassen sich im 19. Jahrhundert nachweisen (z.B. bei John Hersehel, William Whewell oder Hermann von Helmholtz). Ich möchte am Beispiel von Heisenberg der Frage nachgehen, welchen Einfluss die Begründung der Quantenmechanik, die seine Wissenschaftsauffassung prägte, auf den Prozess (...) der Relativierung von Geltungsansprüchen hatte. Meine Vermutung ist, dass eine entscheidende Rolle hierbei weniger dem Wahrscheinlichkeitsbegriff als vielmehr dem Wahrheits- und Realitätsbegriff zukam. Ich werde als erstes den historischen Prozess der Hypothetisierung von Geltungsansprüchen, zu dem ich Heisenbergs Konzeption ins Verhältnis setzen möchte, charakterisieren. Anschließend rekonstruiere ich Heisenbergs Konzeption, soweit sie sich seinen populären Reden und Aufsätzen entnehmen lässt. Als drittes werde ich ihre Wirkungsgeschichte kurz ansprechen und sie mit Wissenschaftsauffassungen vergleichen, die die Bedeutung des Hypothetischen für die modernen Theorien der Naturwissenschaften betonen. Ihnen gegenüber erweist sich Heisenbergs Beitrag als durchaus eigenständig. (shrink)

Helmholtz's public reflection about the nature of the experiment and its role in the sciences is a historically important description, which also helps to analyze his own works. It is a part of his conception of science and nature, which can be seen as an ideal type of science and its goals. But its historical reach seems to be limited in an important respect. Helmholtz's understanding of experiments is based on the idea that their planning, realization and evaluation lies in (...) the hands of a person or group acting according to decisions of free will. In my opinion this idea is characteristic for the foundation of the experimental method in early modern times, not however for several forms of its present structures. Above all, the increasing technization of producing knowledge reduces the roIe of the subject in conducting experiments. My lecture consists of three parts. In its first part I would like to present a summary of Helmholtz's own theory of experiment and the change of his conception of science and nature. In the second part I would like to discuss three examples of his experimental practice, which were taken in chronological order from three different periods of his work; in the third part I would like to compare the examples with the change of his conception of science and nature.

Naturbegriffe beschreiben naturphilosophische Gegenstandsbereiche und fassen Resultate naturphilosophischer Diskurse zusammen. Gehört ihre Bestimmung zu den grundlegenden Aufgaben der Naturphilosophie, so stellt ihre gegenwärtige Vielfalt für die Naturphilosophie eine Herausforderung dar, Von kaum einer wirkungsgeschichtlich bedeutsamen Definition von Natur ist in den letzten Jahrzehnten behauptet worden, ihr komme keine Relevanz für den Diskurs zu. Der Beitrag zeigt Ordnungsstrukturen in der Pluralität der Verwendungsweisen auf und begründet den aktuellen Geltungsanspruch traditioneller Begriffe im Bezug auf spezifische Erfahrungsweisen. Nach einer Einführung beginne ich mit (...) der Unterscheidung von wissenschaftlicher und nichtwissenschaftlicher Naturerfahrung, beziehe auf diese Differenz die Aufgaben der Naturphilosophie und gehe dann mit einer Klassifikation von Naturbegriffen zum exemplarischen Teil über.
