Arbejderne i denne publikation er dels tidligere udgivne tidsskriftartikler, dels ikke før publiceret materiale. De afspejler en vedvarende og relevant forskning i antikkens opfattelse af psyken og af især den sokratiske samtale, som har gennemgribende indflydelse på mange forskellige områder i moderne tid: pædagogik, retsvæsen, sundhedsområdet, retorik osv. Teksterne falder i fire grupper: Sokrates (samtalens logik), Platon (især moralfilosofi og psykologi), Aristoteles (moralfilosofi, gudsbegreb og hverdagsargumentation) og Senere Filosofi (stoisk naturfilosofi, nyplatonisme, Augustins erkendelsesteori, og sjæl-legeme-opfattelsen i antikken). Læseren præsenteres her (...) for en række emner, der vil interessere den, der ønsker at fordybe sig i de ‘evige’ spørgsmål. (shrink)

The present work is an attempt to analyse critically Plato's views on mind and body and more particularly on the mind-body relationship within the wider setting of Plato's metaphysics. We seek to achieve this by a philosophical examination"-of the dialogues on the basis of a generally accepted order. Strictly speaking "soul" ought perhaps to be substituted for "mind" in the above. But it seems to be in terms of "mind" that modern philosophers deal with and refer to the problem that (...) Plato tackled in terms of psyche, and as it is part of the motivation for dealing with Plato's treatment that it is of importance for the modern debate, it has been felt necessary to stress the rough identity* of the problem in the title of the book. Below this superordinate level we try to keep "mind" as a translation typically of nous and "soul" as a translation of psyche. (shrink)

Forms, Matter and Mind. Three Strands in Plato’s Metaphysics -/- This book offers a new interpretation of Plato’s conception of man and of how it develops in the Corpus. Commonly, Plato’s anthropology is considered to be a version of naïve Orphism with the soul being a heavenly, but fallen, daemon. This is shown to be a misleading over-simplification. An examination of three basic and interrelated strands in Plato’s thought (Forms, Matter and Mind) demonstrates how Plato’s conception of man is an (...) integrated part of his metaphysics and develops with it. Thus, a change can be seen from a fairly unreflecting Socratic beginning via a transcendent soul to a rather sophisticated ‘Aristotelianism’. What is at issue is a non-materialistic, or more precisely, a dualistic view of man that has been discredited in modern times by two preconceptions: a widespread opinion that dualism must mean or involve Cartesianism, which seems untenable, and an equally widespread and, until recently, unshaken belief that man can be exhaustively described in materialistic terms. Both assumptions are questioned today. The present work shows that Plato’s view of man is fundamentally different from Cartesianism and furthermore that he rejects the materialist view as well. Hence, the book shows Plato’s increasing relevance for the current debate on the nature and possibilities of man. (shrink)

Ancient Greek Psychology and the Modern Mind-Body Debate offers an overview of Platonic-Aristotelian thought on man with a view to considering what its alternative conceptual framework may contribute to the modern debate which is dominated by the scepticism confronting modern reductionism. -/- The mind-body problem is central to the modern philosophical and cultural debate because we cannot understand what man is until we understand what consciousness is and how it interacts with the body. Although many suggestions have been offered, no (...) convincing account has as yet appeared. Perhaps it was all mistaken ideology from the start? A crucial (and fatal?) distinction was made by modern natural science in the 17th century between the subjective/qualitative and the objective/quantitative. -/- The ancient Greeks, notably Plato and Aristotle, focused not on consciousness and experience, but on goal-directed reason/form, and the contrast was not mechanical matter, but the particular. The latter owed its intelligibility and being to reason and form and did not, therefore, constitute a realm of its own. Hence the ancient picture of man did not fall apart either: the soul is conceived of as a dynamic-telic aspect of the human organism. -/- Considering the problems and consequent scepticism that confronts modern reductionism and the recent appearance of holistic ideology in many areas it is suggested that we take a fresh look at the alternative conceptual framework of our ancient Greek ancestors.

This book offers inter alia a systematic investigation of the actual argumentative strategy of Socratic conversation and explorations of Socratic and Platonic morality including an examination ofeudaimonia and the mental conception of health in the Republic as self-control, with a view to the relation of individual health/happiness to social order. The essays cover a period from 1968 to 2012. Some of them are now published for the first time. Self-motion in the later dialogues involves tripartition and tripartition in turn involves (...) embodiment. The Philebus psychology too anticipates Aristotle. The Forms of the Timaeus are patterns, but the two-world picture is abandoned: there is one world constituted by Forms and Place. The Epinomis is arguably genuine. More generally, denying that Plato develops, e.g. exegetically and psychologically, is absurd. There are too many contradictions in the Corpus. The dialogues are artistic wholes and the author's message must be interpreted accordingly: hence in a sense every character is Plato's mouthpiece. Aristotle's idea of the human good or quality of life as optimal mental activity according to the special human capabilities is the root of the modern selfactualization projects. Panaetius (free reason) and Posidonius (science) mark the end of the older Stoa's hard-core materialism and the beginning of a new more 'modern' era. -/- . (shrink)

This is a defence of the authenticity of Plato’s Epistula vii against the recent onslaught by Frede and Burnyeat (2015). It focusses on what Ep. vii has to say about writing and the embedded philosophical Digression and evaluates this in the context of other mainly late dialogues. In the Cratylus, Socrates ends with resignation regarding the potential of language study as a source of truth. This is also the case in Ep. vii, where the four means of knowledge (names, definitions, (...) images (diagrams) and knowledge/insight/true opinion) do not offer the essence of reality due to the weakness of language, in this case owing to a diagram with contrary properties. Consequently, name and definition are impermanent and conventional. Contra Burnyeat, definition is not impossible but useful in the acquisition of knowledge. Only after dialectical examination comes a flash of insight into reality. So, reality (truth) must, as in the Cratylus, be studied directly. Significantly for Plato (as opposed to Socrates), the epistemology is illustrated by a mathematical case. Hence it is relevant to look at mathematical procedure in middle and late dialogues. Moreover, the possible role of division is considered. Finally, the critique of writing justified by the Digression is placed in the context of the general aversion to the written word. The epistemology of the Digression is shown to be a fair and competent synopsis of the later Plato’s epistemology. Hence, there seems to be no reason thus far to doubt that Ep. vii is a genuine work of Plato. (shrink)

In this international and interdisciplinary collection of critical essays, distinguished contributors examine a crucial premise of traditional readings of Plato's dialogues: that Plato's own doctrines and arguments can be read off the statements made in the dialogues by Socrates and other leading characters. The authors argue in general and with reference to specific dialogues, that no character should be taken to be Plato's mouthpiece. This is essential reading for students and scholars of Plato.

C. S. Lewis is one of the most beloved Christian apologists of the twentieth century; David Hume and Bertrand Russell are among Christianity’s most important critics. This book puts these three intellectual giants in conversation with one another on various important questions: the existence of God, suffering, morality, reason, joy, miracles, and faith. Alongside irreconcilable differences, surprising areas of agreement emerge. Curious readers will find penetrating insights in the reasoned dialogue of these three great thinkers.

The concept of ecosystem services is a way of visualizing the instrumental value that nature has for human beings. Most ecosystem services can be performed by more than one species. This fact is sometimes used as an argument against the preservation of species. However, even though substitutability does detract from the instrumental value of a species, it also adds option value to it. The option value cannot make a substitutable species as instrumentally valuable as a non-substitutable species, but in many (...) cases, it can add enough value to make the species more valuable than the projects that threaten its existence.

Angesichts der ökologischen Krise und der zunehmenden Zivilisationsprobleme ist es notwendig, einen philosophischen Naturbegriff, der das Verhältnis des Menschen zur Natur aufgrund dieser Tatsache neu bestimmt, zu entwickeln. Der Jesuit, Paläontologe und Philosoph Pierre Teilhard de Chardin (1881-1955) ist ein herausragendes Beispiel einer Vermittlung von Naturwissenschaft und Naturphilosophie. Teilhard entwirft eine Zusammenschau von transzendent-metaphysischer Teleologie, die aus dem christlichen Glauben heraus Gott als einzige Zweckursache des Geschehens sieht, philosophischer Anthropologie und naturwissenschaftlich orientierter kausalmechanischer Evolutionstheorie, dem allmählichen Entwickeln eines höheren Zustands (...) aus einem vorhergehenden. Die in der Ursache gegründeten Seinszusammenhänge ergeben einen vom Ziel her bestimmten Zusammenhang. Gott ist Totum alles wirklich Seienden im Horizont des möglichen Seins. Das für Teilhard so wichtige teleologische Prinzip hat seinen philosophiehistorischen Ursprung bei Aristoteles, der damit eine Denktradition begründete, die im Gegensatz zum kausal-mechanischen Weltbild der Naturwissenschaften steht und die sich über Thomas von Aquin und Hegel bis zu Teilhard als vorläufig letztem Höhepunkt erhält. Der aus Teilhards Naturphilosophie folgende Optimismus kann von großer Bedeutung für die Gegenwart sein. Er resultiert aus der Übernahme von Verantwortung für die Schöpfung und ist die ethische Konsequenz aus Naturfinalität und christlichem Universalismus. Der Autor: Erik Lehnert, geb. 1975 in Berlin.

One can (for the most part) formulate a model of a classical system in either the Lagrangian or the Hamiltonian framework. Though it is often thought that those two formulations are equivalent in all important ways, this is not true: the underlying geometrical structures one uses to formulate each theory are not isomorphic. This raises the question of whether one of the two is a more natural framework for the representation of classical systems. In the event, the answer is yes: (...) I state and sketch proofs of two technical results—inspired by simple physical arguments about the generic properties of classical systems—to the effect that, in a precise sense, classical systems evince exactly the geometric structure Lagrangian mechanics provides for the representation of systems, and none provided by Hamiltonian. The argument not only clarifies the conceptual structure of the two systems of mechanics, but also their relations to each other and their respective mechanisms for representing physical systems. It also shows why naïvely structural approaches to the representational content of physical theories cannot work. [Lagrange] grasped that he had gained a method of stating dynamical truths in a way, which is perfectly indifferent to the particular methods of measurement employed in fixing the positions of the various parts of the system. Accordingly, he went on to deduce equations of motion, which are equally applicable whatever quantitative measurements have been made, provided that they are adequate to fix positions. The beauty and almost divine simplicity of these equations is such that these formulae are worthy to rank with those mysterious symbols which in ancient times were held directly to indicate the Supreme Reason at the base of all things.

Logical pluralism is the view that there is more than one correct logic. Most logical pluralists think that logic is normative in the sense that you make a mistake if you accept the premisses of a valid argument but reject its conclusion. Some authors have argued that this combination is self-undermining: Suppose that L1 and L2 are correct logics that coincide except for the argument from Γ to φ, which is valid in L1 but invalid in L2. If you accept (...) all sentences in Γ, then, by normativity, you make a mistake if you reject φ. In order to avoid mistakes, you should accept φ or suspend judgment about φ. Both options are problematic for pluralism. Can pluralists avoid this worry by rejecting the normativity of logic? I argue that they cannot. All else being equal, the argument goes through even if logic is not normative. (shrink)

In Consequentialism Reconsidered, Carlson strives to find a plausible formulation of the structural part of consequentialism. Key notions are analyzed, such as outcomes, alternatives and performability. Carlson argues that consequentialism should be understood as a maximizing rather than a satisficing theory, and as temporally neutral rather than future oriented. He also shows that certain moral theories cannot be reformulated as consequentialist theories. The relevant alternatives for an agent in a situation are taken to comprise all actions that they can perform (...) in the situation. The defense of this idea necessitates certain modifications to the standard consequentialist criteria of obligatoriness, rightness and wrongness. The problem of whether agents should adapt their actions to their own future actions is also addressed. Further, a conditional analysis of performability is suggested, and it is argued that particular actions should in this connection be regarded as `abstract' rather than `concrete'. The final chapter sketches a consequentialist theory for collective agents. (shrink)

Maintaining systems of military plans is critical for military effectiveness, but is also challenging. Plans will become obsolete as the world diverges from the assumptions on which they rest. If too many ad hoc changes are made to intermeshed plans, the ensemble may no longer lead to well-synchronized and coordinated operations, resulting in the system of plans becoming itself incoherent. We describe in what follows an Adaptive Planning process that we are developing on behalf of the Air Force Research Laboratory (...) (Rome) with the goal of addressing problems of these sorts through cyclical collaborative plan review and maintenance. The interactions of world state, blue force status and associated plans are too complex for manual adaptive processes, and computer-aided plan review and maintenance is thus indispensable. We argue that appropriate semantic technology can 1) provide richer representation of plan-related data and semantics, 2) allow for flexible, non-disruptive, agile, scalable, and coordinated changes in plans, and 3) support more intelligent analytical querying of plan-related data.

The book revives the neutral monism of Mach, James, and Russell and applies the updated view to the problem of redefining physicalism, explaining the origins of sensation, and the problem of deriving extended physical objects and systems from an ontology of events.

There are several theses in political science that are usually explicitly called ‘laws’. Other theses are generally thought of as laws, but often without being explicitly labelled as such. Still other claims are well-supported and arguably interesting, while no one would be tempted to call them laws. This situation raises philosophical questions: which theses deserve to be called laws and which not? And how should we decide about this? In this paper we develop and motivate a strategy for thinking about (...) laws in political science which integrates two core concepts: spatio-temporal stability and social mechanisms. The proposed strategy is a set of guidelines that political scientists can use to reflect on and argue about specific cases within their discipline, not a clear-cut demarcation criterion. We defend and motivate this strategy and apply it to two cases (one with respect to state repression, one about parliamentary elections). After we have developed and motivated our strategy for political science, we show that our proposal is relevant for other disciplines in the social sciences. We explain how our views fit into critical realism and embed them in the debate on laws in general philosophy of science and in the philosophy of the social sciences. (shrink)

Erik Wielenberg has presented an objection to divine command theory (DCT) alleging that DCT has the troubling implication that psychopaths have no moral obligations. Matthew Flannagan has replied to Wielenberg’s argument. Here, I defend the view that, despite Flannagan’s reply, the psychopath objection presents a serious problem for the versions of DCT defended by its most prominent contemporary advocates — Robert Adams, C. Stephen Evans, and William Lane Craig.

A consideration of Mach's elements, his philosophy of neutral monism, and philosophy of physics, especially space and time, much of it based on unpublished writings from the Nachlass and other original sources. The historical connection between Mach and logical positivism is shown to be superficial at best, and Mach's elements are shown to be mind independent natural qualities (world-elements) with dynamic force, not limited to human sensations.

In everyday life we often act adequately, yet without deliberation. For instance, we immediately obtain and maintain an appropriate distance from others in an elevator. The notion of normativity implied here is a very basic one, namely distinguishing adequate from inadequate, correct from incorrect, or better from worse in the context of a particular situation. In the first part of this paper I investigate such ‘situated normativity’ by focusing on unreflective expert action. More particularly, I use Wittgenstein’s examples of craftsmen (...) (tailors and architects) absorbed in action to introduce situated normativity. Situated normativity can be understood as the normative aspect of embodied cognition in unreflective skillful action. I develop Wittgenstein’s insight that a peculiar type of affective behaviour, ‘directed discontent’, is essential for getting things right without reflection. Directed discontent is a reaction of appreciation in action and is introduced as a paradigmatic expression of situated normativity. In the second part I discuss Wittgenstein’s ideas on the normativity of what he calls ‘blind’ rule-following and the ‘bedrock’ of immediate action. What matters for understanding the normativity of (even ‘blind’) rule-following, is not that one has the capacity for linguistic articulation or reflection but that one is reliably participating in a communal custom. In the third part I further investigate the complex relationships between unreflective skillful action, perception, emotion, and normativity. Part of this entails an account of the link between normativity at the level of the expert’s socio-cultural practice and the individual’s situated and lived normativity. (shrink)

Ruth Chang has defended a concept of "parity", implying that two items may be evaluatively comparable even though neither item is better than or equally good as the other. This article takes no stand on whether there actually are cases of parity. Its aim is only to make the hitherto somewhat obscure notion of parity more precise, by defining it in terms of the standard value relations. Given certain plausible assumptions, the suggested definiens is shown to state a necessary and (...) sufficient condition for parity, as this relation is envisaged by Chang. (shrink)

In a discussion of Parfit's Drops of Water case, Zach Barnett has recently proposed a novel argument against “No Small Improvement”; that is, the claim that a single drop of water cannot affect the magnitude of a thirsty person's suffering. We first show that Barnett's argument can be significantly strengthened, and also that the fundamental idea behind it yields a straightforward argument for the transitivity of equal suffering. We then suggest that defenders of No Small Improvement could reject a Pareto (...) principle that is presupposed in Barnett's argument and our developments of it. However, this does not save No Small Improvement, since there is a convincing argument against this claim that does not presuppose the Pareto principle. (shrink)

John Broome has argued that incomparability and vagueness cannot coexist in a given betterness order. His argument essentially hinges on an assumption he calls the ‘collapsing principle’. In an earlier article I criticized this principle, but Broome has recently expressed doubts about the cogency of my criticism. Moreover, Cristian Constantinescu has defended Broome’s view from my objection. In this paper, I present further arguments against the collapsing principle, and try to show that Constantinescu’s defence of Broome’s position fails.

Much controversy surrounds the question of what ought to be the proper definition of 'singularity' in general relativity, and the question of whether the prediction of such entities leads to a crisis for the theory. I argue that a definition in terms of curve incompleteness is adequate, and in particular that the idea that singularities correspond to 'missing points' has insurmountable problems. I conclude that singularities per se pose no serious problem for the theory, but their analysis does bring into (...) focus several problems of interpretation at the foundation of the theory often ignored in the philosophical literature.

A full appreciation for Ernst Mach's doctrine of the economy of thought must take account of his direct realism about particulars (elements) and his anti-realism about space-time laws as economical constructions. After a review of thought economy, its critics and some contemporary forms, the paper turns to the philosophical roots of Mach's doctrine. Mach claimed that the simplest, most parsimonious theories economized memory and effort by using abstract concepts and laws instead of attending to the details of each individual event (...) or experiment. For Mach, the individual case never truly repeated in all of its uniqueness, nor was all of the individual detail of a physical element adequately captured in abstract laws and schemata, however necessary these were for the pursuit of science. As can be shown from specific passages, some already published, some not, Mach's elements included physical qualia in nature similar to Russell's unsensed sensibilia, which existed even where there were no conscious observers. An argument will be presented to make the case that Mach believed in the mind-independent elements from the 1870s on, while other aspects of his thought evolved over time; I have thus dated the references to reflect this historical progression. I concentrate on Mach's ontology, as it bears on economy of thought, not his epistemology per se, which might well have been restricted to observable elements/sensations. After his own conversion to neutral monism, in the 1920s, Bertrand Russell echoed Mach's call for a 'future science' capable of handling the 'intrinsic character' of qualitative data directly without the excessive abstraction of physics.

Why do corporations and wealthy philanthropists fund the human sciences? Examining the history of the Santa Fe Institute (SFI), a private research institute founded in the early 1980s, this article shows that funders can find as much value in the social worlds of the sciences they sponsor as in their ideas. SFI became increasingly dependent on funding from corporations and libertarian business leaders in the 1990s and 2000s. At the same time, its intellectual work came to focus on the underlying (...) principles of adaptation, innovation, and decentralized coordination supposedly at work in ‘complex systems’ from biological ecosystems to markets and firms. This research cast the ideas of the libertarian economist Friedrich Hayek into a new scientific idiom. SFI also became a space where figures in business, media, academia, and politics could come to learn to see the world in a particular way—to acquire the subjectivity of what I call ‘the Santa Fe Institute libertarian’. At SFI, visitors did not simply learn the principles of neo-Hayekian complex system science. They came to see themselves as agents of social evolution, providing the spark that the free-market system needed to produce new technologies and new solutions to social problems without top-down political direction. For the Institute's corporate and libertarian financiers, SFI was not just a space where intellectuals described the world in favored ideological terms, but a space where elite actors became committed to the project of making a new political-economic order.

Neutral monism is a position in metaphysics defended by Mach, James, and Russell in the early twentieth century. It holds that minds and physical objects are essentially two different orderings of the same underlying neutral elements of nature. This paper sets out some of the central concepts, theses and the historical background of ideas that inform this doctrine of elements. The discussion begins with the classic neutral monism of Mach, James, and Russell in the first part of the paper, then (...) considers recent neo-Russellian versions in the second half. The chances for a revival of neutral monism are probably slight; its key ideas and starting points lie far from those in contemporary philosophy of mind. A better route might be through the philosophy of science and a deeper understanding of causation. (shrink)

Many philosophers have claimed that normative error theorists are committed to the claim ‘Error theory is true, but I have no reason to believe it’, which to some appears paradoxical. Case (2019) has claimed that the normative error theorist cannot avoid this paradox. In this paper, we argue that there is no paradox in the first place, that is once we clear up the ambiguity of the word ‘reason’, both on the error theorist’s side and those that claim that there (...) is a self-defeat problem. Upon clarification, we also raise scepticism to what exactly the nature of self-defeat is meant to be. (shrink)
