Ziel der Untersuchung ist zu zeigen, inwiefern Hegels Charakterisierung des Schönen als ‚das sinnliche Scheinen der Idee‘ auch für die Deutung des Naturschönen Erklärungswert hat. Vorausgesetzt ist die für den Idea- lismus Hegelscher Prägung zentrale Doktrin, derzufolge der Natur Ideel- les zugrunde liegt. Schön sind dann Naturphänomene, in denen jener ideelle Grund der Natur durchscheint. Das Erfassen von Ideellem scheint ein Privileg geistiger Wesen zu sein. Dem stehen evolutionsbiologische Argumente entgegen, die dem Schönen einen positiven Selektionswert, etwa bei der sexuellen (...) Partnerwahl, zusprechen. Auch der Mensch hat stammesgeschichtliche Wurzeln, die in ihm weiter wirken. Doch sobald der Geist auf der evolutionären Bühne erscheint, herrscht das Biologische nicht länger mit der uneingeschränkten Macht, die es im Rahmen natürli- cher Selektion hat. Hegels Deutung des Schönen, auch des Naturschönen, ist wesentlich bezogen auf den Geist. Ich verdeutliche dies an einigen Exempeln (Schneekristall, musikalische Harmonie, Abendhimmel, Ge- birgslandschaft, organische Blüten- und Körperformen). Aber wodurch sind Naturschönheit und Kunstschönheit dann voneinander unterschie- den? Die Hervorbringungen der Natur sind lediglich Zufallskonstellatio- nen. Allerdings, so Hegel, hat der Zufall es ‘recht’ gemacht, d.h. hat er etwas reizend Stimmiges gefügt, gewahrt der Geist darin das im Sinnli- chen durchscheinende Ideelle. Eben darin wird, mit Adorno gesprochen, die gemeinsame Wurzel des Kunstschönen und des Naturschönen erkennbar. Wer das Naturschöne preist, begebe sich „an den Rand der Afterpoe- sie“, des Kitsches, meint Adorno. Gleichwohl sei es wahr zu sagen, „die Landschaft der Toscana sei schöner als die Umgebung von Gelsenkirchen“ (Adorno 1993, 110, 112). In der Tat. Doch was meinen wir, wenn wir Landschaften, Blumen, Sonnenuntergänge ‘schön’ nennen, und welche Kriterien bringen wir dafür in Anschlag? Im Folgenden möchte ich darle- gen, inwiefern Hegels Charakterisierung des Schönen als „das sinnliche Scheinen der Idee“ diesbezüglich erhellend und klärend ist. Hinweise auf Adornos ästhetische Theorie ergänzen diese Überlegungen. Dem stehen evolutionsbiologische Argumente entgegen, die zunehmend Einfluss auf die ästhetische Diskussion gewinnen. (shrink)

The Cartesian concept of nature, which has determined modern thinking until the present time, has become obsolete. It shall be shown that Hegel's objective-idealistic conception of nature discloses, in comparison to that of Descartes, new perspectives for the comprehension of nature and that this, in turn, results in possibilities of actualizing Hegel's philosophy of nature. If the argumentation concerning philosophy of nature is intended to catch up with the concrete Being-of-nature and to meet it in its concretion, then this is (...) impossible for the finite spirit in a strictly a priori sense – this is the thesis supported here which is not at all close to Hegel. As the argumentation rather has to consider the conditions of realization concerning the Being-of-nature, too, it is compelled to take up empirical elements – concerning the organism, for instance, system-theoretical aspects, physical and chemical features of the nervous system, etc. With that, on the one hand, empirical-scientific premises are assumed (e.g. the lawlikeness of nature), which on the other hand become (now close to Hegel) possibly able to be founded in the frame of a Hegelian-idealistic conception. In this sense, a double strategy of empirical-scientific concretization and objective-idealistic foundation is followed up, which represents the methodical basic principle of the developed considerations. In the course of the undertaking, the main aspects of the whole Hegelian design concerning the philosophy of nature are considered – space and time, mass and motion, force and law of nature, the organism, the pro-blem of evolution, psychic being – as well as Hegel's basic thesis concerning the philosophy of nature, that therein a tendency toward coherence and idealization manifests itself in the sense of a (categorically) gradually rising succession of nature: from the separateness of space to the ideality of sensation. In the sense of the double strategy of concretization and foundation it is shown that on the one hand possibilities of philosophical penetration concerning actual empirical-scientific results are opened, and on the other hand – in turn – a re-interpretation of Hegel's theorem on the basis of physical, evolution-theoretical and system-theoretical argumentation also becomes possible. In this mutual crossing-over and elucidation of empirical and Hegelian argumentation not only do perspectives of a new comprehension of nature become visible, but also, at the same time – as an essential consequence of this methodical principle – thoughts on the possibilities of actualizing Hegel's philosophy of nature.

My argument is that Chalmers' zombie fiction and his rigid-designator-argument going back on Kripke comes down to a petitio principii. Rather, at the core it appears to be more related to the essential 'privacy' of the phenomenal internal perspective. In return for Chalmers I argue that the 'principle self-preservation' of living organisms necessarily implies subjectivity and the emergence of sense. The comparison with a robot proves instructive. The mode of 'mere physical' being is transcended if, in the form of phenomenal (...) perception, sense appears on the stage of higher animals – a transition explained here as an emergence phenomenon based on the systemic co-operation of perception, valuation and action ('perc-val-act system'). Some fundamental considerations are added: Those consequences implied by the principle self-preservation reveal the natural-biological origin of the organism – primarily seeming a more insignificant circumstance – as a momentous fundamental difference (end-in-itself-character, subjectivity, constitution of sense) compared to technical artefacts (robot). And the emergentist approach indicates the – maybe paradoxical – possibility of a dualism of physical and psychical phenomena in an overall physical system, that is not dualistic at the same time. (shrink)

The study ties in with former considerations concerning the problem of phenomenal perception of higher animals. Accordingly the phenomenal character, qualia included, results from the adjustment of perceptions to (typal) behavioral dispositions under the principle of self-preservation: an emergence phenomenon provided by the constitutive system unity of perception and behavior, here characterized as percept-act-system. Thereby the subject of behavior can be explained as an emergent instance of the – system-theoretically highest rank – percept-act-level. In terms of the principle of self-preservation (...) it subjects all sensations to an valuation. Perception thus gaining existential sense for the subject, a psychic sense-dimension is spanned which as such does not own physical but ideal character. Accessing Hegel this is further interpreted: Accordingly the ontological basis of this view is the lawfulness of nature, understood as the ideal essence underlying it. In virtue of this – basically Hegelian-type idealistic – conception the material being of nature always encloses the possibility of the psychic, according to that ideal substratum of nature.

The center of this investigation is the ‘real hard problem’ of phenomenal perception (Chalmers), i.e. of the qualitative kind of perception presenting the subject with forms, colors, smell, pleasurable or negative feelings etc.; the problem of Human consciousness, however, will explicitly not be treated. The ‘explanatory gap’ (Levine) complained by the philosophy of mind, that is to say the failure of all attempts to supply a neuronal explanation of experiences, is emergence-theoretically treated: Systems own properties and laws different from their (...) components; so the emergence concept shows promise also for the explanatory potential with respect to neuronal systems. Here the phenomenal character of perception is explained from the systemic co-action of perception and behavior, whereby also an interpretation is opened to Davidson’s anomal monism. Qualitative feelings, as is further shown, are not to be understood as needless ‘epiphenomena’, but as a necessary completion of per-ception when, as in the case of higher animals, the behavior is primarily controlled by phenomenal perception.

Our starting point is the question ‘What is mass’, what in particular enables mass to constitute duration: so that mass can be regarded as moving as well as at rest (the kinematic principle of relativity). In a thought experiment, this question is attacked here not from the perspective of mass itself, but from that of a standing light wave. In this model, mass-analogous structures can be re- constructed that can be in relative motion to each other. The (empirically known) constancy (...) of the speed of light in every reference system is not as- sumed here. However, it can be shown that the speed of light is identical in all systems constituted by mass-analogous structures that move uniformly relative to each other and that the speed of light moreover is the limiting speed of mo- tions. This indepence of the motion of light from the system of reference, this character of absoluteness, and the relativity of mass motions thus prove to be contrary but inextricably linked moments of the kinematic principle of relativi- ty: an interesting perspective concerning a philosophy of relativity theory. - The mathematical relationships are explained in more detail in the appendix.

Ausgangspunkt ist die Frage, was Masse ist, wodurch sie insbesondere befähigt ist, Dauer zu konstituieren und deshalb - im Sinn des kinematischen Relativitätdprinzips - ebenso als bewegt wie als ruhend betrachtet werden kann. In einem Gedankenexperiment wird diese Frage, in Umkehrung der Perspektive, hier nicht von der Masse selbst, sondern von einer stehenden Lichtwelle her angegangen. In diesem Modell lassen sich masse-analoge Strukturen rekonstruieren, die in relativer Bewegung sein können. Die (empirisch bekannte) Unabhängigkeit der Lichtgeschwindigkeit vom Bezugssystem ist dabei nicht (...) vorausgesetzt. Doch kann gezeigt werden, dass die Lichtgeschwindigkeit Grenzgeschwindigkeit solcher relativer Bewegungen ist, dass dies für alle durch masse-analoge Strukturen konstituierte, relativ zueinander gleichförmig bewegten Bezugssysteme gilt und dass die Lichtgeschwindigkeit selbst in allen diesen Systemen gleich ist. Die Absolutheit der Lichtgeschwindigkeit und die Relativität der Massebewegungen erweisen sich so als zwar differente, aber intrinsisch zusammengehörende Momente des kinematischen Relativitätsprinzips: ein Beitrag zu einer Philosophie der Relativitätstheorie. - Die mathematischen Zusammenhänge werden im Anhang ausführlicher dargelegt.

Summary: Kant's characterization of organic entities by the principle of an inner, and that is to say, immanently natural and mind-independent purposiveness has continued to retain validity. Difficulties however exist for Kant's theory from the conditions of their realization. The following inquiry attempts to describe to what extent this difficulty has currently found a system-theoretical solution: The realizability of cyclical causal relationships proves itself here to be a fundamental prerequisite. The possibility for self-regulating systems thus consequently ensues. Decisive for the (...) cybernetical reconstructability of inner purposiveness is however the evidence that the principle of self-regulation - which has apparently been misunderstood in recent discussions (Jonas, Spaemann, Löw) includes not only the possibility of active goal pursuance (robots) but, additionally, the possibility forexistential self-reference (organism). This has fostered greater insight into how normative instances can be established upon a purely physical basis. The status of information will then accordingly be questioned. This inquiry closes with a look to possible ontological consequences. (shrink)

Transzendental wird hier, abweichend von Kant, im Sinn transzendentaler Argumente verstanden. Im Kontext der Letztbegründungsdiskussion sind diese dadurch definiert, dass ihre Verneinung zu einem pragmatischen Widerspruch führt. Nun ist Hegels Philosophie auf die ‚logische Idee‘ gegründet, also auf die in Hegels Verständnis fundamentale dialektische Logik. Sein philosophischer Systementwurf hat dadurch, wie gezeigt wird, transzendentalen Charakter und schließt dementsprechend auch eine transzendentale Naturphilosophie ein. Gezeigt wird weiter, dass Grundbe- stimmungen der Natur, die üblicherweise einfach vorausgesetzt werden, in diesem Rahmen grundsätzlich erklärt (...) werden können: die Existenz der Natur und ihr (räumlich-zeitliches) Auseinandersein, ferner die Erkenn- barkeit der Natur, ihre Gesetzmäßigkeit, Kontingenz und immanente Idea- lisierungstendenz. Dass sich so auch konkrete Naturphänomene erschließen, wird an zwei Exempeln verdeutlicht: in der Begründung dimensionaler Raumstrukturen und in der Begründung des Relativitätsprinzips der Bewe- gung – letzteres mit der Pointe (im Sinn einer Philosophie der (speziellen) Relativitätstheorie), dass die Relativität der Körperbewegung und die Absolutheit der Lichtbewegung so als logisch zusammengehörende Momente kinematischer Relativität verstehbar werden.

Seele kommt zweifellos schon ‚höheren‘ Tieren zu, die als solche über phänomenale Wahrnehmung verfügen. Als aufschlussreich erweist sich der kontrastierende Vergleich von Tier und Roboter: Was hat das Tier, was der Roboter nicht hat? Schlüsselfunktion kommt hier Hegels Deutung zu, die als eine Phänomenologie der ‚animalischen Seele‘ angesprochen werden kann. Sein Diktum ‚Nur ein Lebendiges fühlt Mangel‘ verweist auf das alles Organische durchwaltende Prinzip Selbsterhaltung als Grund des Seelischen: Alles, was das Tier wahrnimmt, hat dadurch existentiellen Sinn, Selbsterhaltungs-Sinn. Zugleich wird (...) deutlich, dass die Roboter-Wahrneh- mung nicht zur Sinn-Konstitution befähigt, sondern durch Sinn-Demenz charakterisiert ist. Konkret-systemtheoretisch wird die Sinnbezogenheit des Tiersubjekts hier als Emergenzphänomen desjenigen Systems gedeutet, das durch die Kooperative von Wahrnehmung, Bewertung und Verhalten (Perc-Eval-Act-System) konstituiert wird. In dieser emergentistischen Perspektive gibt es so gleichsam den Dualismus des ‚bloß Physischen‘ und des Ideell-Seelischen, der im Hinblick auf die insgesamt physische Basis zugleich ein Monismus ist.

The well-known empiricist apories of the lawfulness of nature prevent an adequate philosophical interpretation of empirical science until this day. Clarification can only be expected through an immanent refutation of the empiricist point of view. My argument is that Hume’s claim, paradigmatic for modern empiricism, is not just inconsequent, but simply contradictory: Empiricism denies that a lawlike character of nature can be substantiated. But, as is shown, anyone who claimes experience to be the basis of knowledge (as the empiricist naturally (...) does), has, in fact, always already presupposed the lawfullness of nature, i.e. has assumed the ontology of a nature lawful in itself. If lawfulness is, more closely, understood as dependency on conditions, then the functional character of the laws of nature is involved with the consequence that verification is not to be taken as a mere repetition of measurements but as clarification of the conditional structure of the physical process. Furthermore the functionality of the laws of nature also includes a statement on their invariance (relative to certain transformations) and so their lawlikeness. This throws a new light on the problem of induction. Seen in this way it is hardly surprising that the notorious neglect of the functional aspect in empiricism has led to fundamental problems with the concept of the law of nature. (shrink)

Without doubt already ‘higher’ animals which as such have phenomenal perception possess an animalic soul. The contrasting comparison of animal and robot proves to be revealing: What does the animal have that the robot does not? A key role here plays Hegel’s interpretation, which can be addressed as a phenomenology of the ‘animalic soul’. His dictum ‘Only what is living feels a lack’ refers to the principle of self-preservation which governs everything organic. Concerning higher animals this too appears as the (...) basis of the soul: Everything, which the animal perceives thus has existential sense, self-preservation-sense. At the same time it becomes clear that robot perception is not capable of a constitution of sense, but is characterized by dementia of sense. Concretely systemtheoretically regarded, the relatedness to sense of the animal subject is here interpreted as an emergence phenomenon of the system constituted by the cooperative of perception, valuation and behavior (perc-val-act-system). In this emergentist perspective, there is, as it were, the dualism of solely-physical being and of immaterial-mental being, which at the same time is a monism with regard to the physical basis alltogether.

The present investigation brings into view the philosophy of nature of German Idealism, a philosophical movement which emerged around the beginning of the nineteenth century. German Idealism appro- priated certain motivations of the Kantian philosophy and developed them further in a "speculative" manner (Engelhardt 1972, 1976, 2002). This powerful philosophical movement, associated above all with the names of Fichte, Schelling and Hegel - and moreover having nothing whatsoever to do with the "subjective idealism" of George Berkeley - was replaced by (...) philosophical positions designated roughly as metaphysics of the will, Marxism, life-philosophy, phenomenology and existentialism, as well as positivism, empiricism, philosophy of science, the linguistic turn, and analytic philosophy. These philosophical positions more or less still shape us today. German Idealism amounts to a virtual intellectual-historical antithesis to these movements and thus presents itself in retrospect as a striking alternative. The basis of Idealism - in its various respective forms - is the ideal <Ideelle>, and thus the opposite of that which is real. It continually takes as its task explaining the real in terms of the ideal, and this is especially true of the Idealists' philosophy of nature.' Is this a hopeless undertaking? Does Idealism not lack an empirical basis? Can one secure any solid ground whatsoever in the ether of the ideal? In what follows, I explain how, more than anyone else, Schelling and Hegel sought to handle this problem and to cope with it. By way of anticipation, a clear preference for the Hegelian philosophy of nature will emerge in what follows, a preference which may come as some surprise considering how much controversy has surrounded the significance of that view. The project of renewing a thoroughgoing philosophy of nature can meaningfully begin here. (shrink)

The scope of my considerations here is defined along two lines, which seem to me of essential relevance for a theory of dialectic. On the one hand, the form of negation that – as self-referring antinomical negation – gains a quasi-semantic expulsory force [Sprengkraft] and therewith a forwarding [weiterverweisenden] character; on the other hand, the notion that every logical category is defective insofar as the explicit meaning of a category does not express everything that is already implicitly presupposed for its (...) meaning. Both lines are tightly interwoven. This I would like to demonstrate with the example of the dialectic of Being and Non-Being at the beginning of the Hegelian Logic. I will first make visible the basic structures of dialectical argumentation (sections II and III) – whereby certain revisions will turn out to be necessary in comparison with Hegel’s actual argument. Thereby it proves essential that the whole apparatus of logical categories and principles must be always already available and utilized for the dialectical explication: proving dialectic as a self-explication of logic by logical means: dialectic, as it were, as the self-fulfillment of logic (sections IV–VI). (shrink)

The status of being a subject, a self and being self-aware of it, is to be interpreted here through the process of the child‘s role play with the doll: By speaking to the doll, this inanimate being is seen as animate and becoming the alter ego of the child. Communicating with it thus means that the child speaks to it- self. It has thus established a — so to speak 'tautological‘ — self-relationship, a behavior in which it encounters only figures (...) of itself. This effect of reflexive tautologization, as I would like to say briefly, is decisive: The individual does not gain a self be- cause he puts himself in the other´s place — think of G.H. Mead — but because he rather eliminates the moment of otherness by means of reflexive tautologization and thus, in tautological self-execution, constitutes himself as self and ultimately as self- consciousness: role-playing as the self-fulfilling design of self- hood. Implicated thereby is, according to my argument, that the self-interpretation of the subject as free or as determined is essentially to be conceived as a self-fulfilling design — free is he who (with all conditionalities) 'designs' himself as free. And in turn, the demand for mutual recognition of the subjects results from this as well. ************************************************************************************************* Der Status, ein Subjekt, ein Selbst und dessen sich selbst bewusst zu sein, soll hier am Vorgang des kindlichen Rollenspiels mit der Puppe gedeutet werden: lndem das Kind zur Puppe spricht, kann dieses an sich Leblose begeistet und zum Alter Ego werden. Mit ihm kommunizieren bedeutet somit, dass das Kind vielmehr zu sich selbst spricht. Es hat damit ein — gleich- sam 'tautoIogisches‘ — Selbstverhältnis hergestellt, ein Verhal- ten, in dem ihm nur Gestalten seiner selbst begegnen. Dieser Effekt reflexiver Tautologisierung, wie ich kurz sagen möchte, ist entscheidend: Das lndividuum gewinnt nicht deshalb ein Selbst, weil es sich in den Andern versetzt — man denke an G.H. Mead —, sondern weil es vermittels reflexiver Tautologi- sierung das Moment der Andersheit vielmehr eliminiert und sich so, im tautologischen Selbstvollzug, als Selbst und letztlich als Selbst-Bewusstsein konstituiert: Rollenspiel als sich selbst er- füllender Entwurf von Selbstsein. lmpliziert ist damit, so mein Argument, dass die Selbstdeutung des Subjekts als frei oder als determiniert, essentiell als selbsterfüllender Entwurf zu be- greifen ist — frei ist, wer sich (bei allen Bedingtheiten) als frei 'entwirft'. Und im Gegenzug ergibt sich die Forderung wechsel- seitiger Anerkennung der Subjekte ebenso daraus. (shrink)

Hegel's Science of Logic makes the just not low claim to be an absolute, ultimate-grounded knowledge. This project, which could not be more ambitious, has no good press in our post-metaphysical age. However: That absolute knowledge absolutely cannot exist, cannot be claimed without self-contradiction. On the other hand, there can be no doubt about the fundamental finiteness of knowledge. But can absolute knowledge be finite knowledge? This leads to the problem of a self-explication of logic (in the sense of Hegel) (...) and further, as will be shown, to a new definition of the dialectical procedure. The stringency of which results from the fact that always exactly that implicit content is explicated that was generated by the preceding explication step itself and is thus concretely comprehensible. At the same time, a new implicit content is generated by this act of explication, which requires a new explication step, and so forth. In the dialectical procedure reinterpreted in this way, dialectical arguments are not beheld, guessed at or even surreptitiously obtained, but are methodically accountable. Thereby dialectics is understood as a self-explication of logic by logical means and thus as a proof of the possibility of ultimate-grounding in the form of absolute and nevertheless finite – and thus also fallible – knowledge.

The center of this investigation is the hard problem of phenomenal perception. To be clear, hereby it is thought of higher animals; accordingly the problem of Human consciousness will explicitly not be treated. The so-called explanatory gap (Levine), i.e. missing a neural explanation of experiences, here is emergence-theoretically countered: It is argued that systems own properties and laws different from those of their components. Applied to the brain the phenomenal character of perception is explained as an emergence effect from the (...) systemic cooperation of perception, valuation and behavior, whereby also an interpretation is opened to Davidson’s anomal monism. As is further shown, feelings are to be understood as a necessary completion of perception when, as in the case of higher animals, the behavior is primarily controlled by phenomenal perception.

First I argue that the prohibition of linguistic self-reference as a solution to the antinomy problem contains a pragmatic contradiction and is thus not only too restrictive, but just inconsistent (chap.1). Furthermore, the possibilities of non-restrictive strategies for antinomy avoidance are discussed, whereby the explicit inclusion of the – pragmatically presuposed – consistency requirement proves to be the optimal strategy (chap.2). The central question here is that about the actual reason for antinomic structures. It turns out to be a form (...) of negative self-conditioning (chap.3). This makes it necessary to clarify the status of negative concepts (chap.4). The generalization of these considerations (chap.5) leads to the actual analysis of the antinomic basic structure (chap.6): Decisively for the pragmatics of the concept is that it positively owns a meaning, so that positivity is always constituted by the concept qua concept. Thus a negative concept is characterized by a fundamental ambivalence: From a semantic point of view it has negative character, in its pragmatic status as a concept, however, it has positive character. If the meaning is especially that of a negative self-reference, the ambivalence leads to the antinomic constellation of a negative self-condition – that is the crux of the matter here! The concept thus possesses the property defined by it exactly when it does not possess it and vice versa. A closer analysis shows that the function of reflective structures for the occurrence of antinomies has to be judged much more differentiated than previous opinions suggest. Not only are four forms of reflectivity to be distinguished in this context – ontic, semantic, pragmatic reflectivity, and especially the form of negative self-condition; but it is also apparent that these are intertwined with each other in a way that is difficult to be understood. The astonishing variety of relationships associated with this makes the irritation that has always emanated from the antinomy problem appear more comprehensible. In the developed pragmatic perspective furtheron parallels to the structure of self-consciousness become visible (chap.7). I conclude with considerations about the significance of the antinomic structure for the problem of dialectics, especially for the synthesis formation of mutually exclusive terms (chap.8). ---------- Zunächst wird gezeigt, dass das Verbot sprachlicher Selbstreferenz als Lösung des Antinomienproblems einen pragmatischen Widerspruch enthält und damit nicht nur zu restriktiv, sondern geradezu inkonsistent ist (Kap.1). Ferner werden Möglichkeiten nicht-restriktiver Strategien zur Antinomienvermeidung diskutiert, wobei sich die explizite Einbindung der – pragmatisch präsupponierten – Konsistenzforderung als optimale Strategie erweist (Kap.2). Zentral ist hier die Frage nach dem eigentlichen Grund antinomischer Strukturen. Er erweist sich als eine Form von negativer Selbst-Bedingung (Kap.3). Dies nötigt zu einer Klärung des Status negativer Begriffe (Kap.4). Die Verallgemeinerung dieser Überlegungen (Kap.5) leitet über zur eigentlichen Analyse der antinomischen Grundstruktur (Kap.6): Entscheidend zur Pragmatik des Begriffs gehört, dass ihm eine Bedeutung positiv zukommt, sodass durch den Begriff qua Begriff stets auch Positivität konstituiert ist. Dadurch ist ein negativer Begriff durch eine prinzipielle Ambivalenz gekennzeichnet: In semantischer Hinsicht hat er negativen Charakter, in seinem pragmatischen Status als Begriff hingegen positiven Charakter. Ist die Bedeutung insbesondere die eines negativen Selbstbezugs, führt die Ambivalenz zur antinomischen Konstellation einer negativen Selbst-Bedingung – das ist hier der springende Punkt! Der Begriff besitzt so die durch ihn definierte Eigenschaft genau dann, wenn er sie nicht besitzt und umgekehrt. Die nähere Analyse zeigt, dass hierbei die Funktion reflexiver Strukturen für das Auftreten von Antinomien weitaus differenzierter zu beurteilen ist, als bisherige Auffassungen nahelegen. Nicht nur dass in diesem Kontext vier Formen von Reflexivität – ontische, semantische, pragmatische Reflexivität und insbesondere auch die Form negativer Selbstbedingung – unterschieden werden müssen; es zeigt sich auch, dass diese in schwer durchschaubarer Weise ineinander verschränkt sind. Die damit verbundene erstaunliche Beziehungsvielfalt läßt die Irritation, die seit je vom Antinomienproblem ausging, begreiflicher erscheinen. In der entwickelten pragmatischen Perspektive werden ferner Parallelen zur Struktur von Selbstbewußtsein sichtbar (Kap.7). Ich schließe mit Überlegungen zur Bedeutung der antinomischen Struktur für das Problem der Dialektik, insbesondere zur Synthesebildung einander ausschließender Bestimmungen (Kap.8). (shrink)

The zombie, mocking all nomological arguments, gives rise to axiological considerations that also result in a vindication of the nomological paradigm. So the ‘philosophical benefit of zombies’ ultimately proves to be that they lead to an understanding they were originally invented to refute.

Since there is no really elaborated theory of the dialectic of nature, it is not only desirable but necessary to take a look at some of Hegel's original intuitions, which in many cases lost their distinctness in his later works, or fell victim to the exigencies of his system. Philosophy makes use not only of reasoning but also of intuition. In respect of the mass which offers persistent resistance to a notional solution, it is important to find a suitable image (...) for developing a first approximation to the understanding of the question. According to Hegel, the metaphors of circular and gyratory motion are well-suited for this. Here it is essential to clarify what we can gain by a structural interpretation of such ideas. I think that an attempt has to be made to bring out the contemporary relevance of the topic. Doing so is always a delicate matter, but it is a must if undertakings of the present kind are to be anything more than philological expositions of Hegel's philosophy, if they are to make a real contribution to reflection on the foundations of physics. I shall first give a brief review of the arguments put forward in the Encyclopedia; then I shall analyse Hegel's interpretation of circular and gyratory motion and discuss the possibility of bringing out the relevance of his ideas; finally, I shall draw certain conclusions in respect of the principles involved in comprehending the divisibility of matter, and in putting forward a philosophical interpretation of the theory of relativity.

There are arguments for determinism. Admittedly, this is opposed by the fact of everyday experience of autonomy. In the following, it is argued for the compatibility of determinism and autonomy. Taking up considerations of Donald MacKay, a fatalistic attitude can be refuted as false. Repeatedly, attempts have been made to defend the possibility of autonomy with reference to quantum physical indeterminacy. But its statistical randomness clearly misses the meaning of autonomy. What is decisive, on the other hand, is the possibility (...) of knowledge, which opens up opportunities for planning, freedom of choice and ultimately 'self-choice'. Results of neurobiological research, especially Benjamin Libet's and more recently John-Dylan Haynes', seem to refute this: Actions are unconsciously initiated before conscious decision. But, as Libet has also shown, consciousness always has the possibility of a veto – and thus also of knowledge-driven action control. Ultimately, the idea of possible self-choice can thus become the determining condition. Only such a form of rational self-determination establishes a spiritual identity and at the same time represents the maximum of autonomy possible for human beings. (shrink)

What corresponds to the present-day ‘transcendental-pragmatic’ concept of ultimate grounding in Hegel is his claim to absoluteness of the logic. Hegel’s fundamental intuition is that of a ‘backward going grounding’ obtaining the initially unproved presuppositions, thereby ‘wrapping itself into a circle’ – the project of the self-grounding of logic, understood as the self-explication of logic by logical means. Yet this is not about one of the multiple ‘logics’ which as formal constructs cannot claim absoluteness. It is rather a fundamental logic (...) that only makes logical textures possible at all and so owns transcendental character. The non-contradiction-principle is an example for this. Es- sential is that it is ‘under-cover-effcient’ as soon as meaningful concepts are used. Self-explication of the fundamental logic then means explicating its implicit under-cover validity, in fact by means of the fundamental logic itself. As is shown this is the affair of dialectic which thereby is to be understood as ultimate grounding of the fundamental logic. This is analyzed in detail using the example of the being/non-being-dialectic. As is demonstrated each explication step generates a new implicit issue and therewith a new explication-discrepancy inducing an antinomical structure that anew forwards the explication procedure. So this is entirely determined by itself. Decisive for the ultimate grounding argumentation is that thereby an objectively verifyable procedure is found, which is apparently possible only in a Hegelian framework. In contrast the immediate evidence of a speech act claimed by the transcendental-pragmatic position has only private character, which is grounding-theoretically irrelevant. (shrink)

Previous efforts to bring the Hegelian dialectic closer to a clarification give reason for skepticism. The question: "What is dialectic", according to Dieter Henrich, "has remained without an answer so far". Hegel's objective-idealistic program is, however, so much linked to the possibility of a dialectical logic that it is an urgent desideratum to gain clarity about the stringency of dialectical argumentation. But this is only possible on the basis of a theory of dialectic. Hegel's own reflection on methods cannot be (...) considered sufficient in this respect. It does not enable us to defend the dialectical procedure against objections or to answer questions of method. In the following, a detailed reconstruction of the dialectic of 'being' and 'nothing' in Hegel's 'Science of Logic' will reveal basic structures of dialectical argumentation. As will be shown, antinomic structures play a key role. Such a 'reconstruction', however, will not be a simple confirmation of Hegelian texts, but will always have the character of a critique. In fact, it will turn out that in comparison with Hegel's development of categories, radical revisions are to be expected. ----- Bisherige Bemühungen, das Verfahren Hegelscher Dialektik einer Klärung näherzubringen, geben Anlass zur Skepsis. Die Frage: „Was ist Dialektik?“, so Dieter Henrich, sei „bisher ohne Antwort geblieben“. Das objektiv-idealistische Programm Hegels ist indes so sehr mit der Möglichkeit einer dialektischen Logik verknüpft, daß über die Stringenz dialektischer Argumentation Klarheit zu gewinnen ein dringliches Desiderat darstellt. Das aber ist nur auf der Grundlage einer Theorie der Dialektik möglich. Hegels eigene Methodenreflexion kann diesbezüglich nicht als zureichend erachtet werden. Sie versetzt uns nicht in die Lage, das dialektische Verfahren gegen Einwände zu verteidigen oder Methodenfragen zu beantworten. Im Folgenden sollen in einer detaillierten Rekonstruktion der Dialektik von ‘Sein’ und ‘Nichts’ in Hegels ‘Wissenschaft der Logik’ Grundstrukturen dialektischer Argumentation sichtbar gemacht werden. Wie gezeigt wird, kommt dabei antinomischen Strukturen eine Schlüsselfunktion zu. Eine solche 'Rekonstruktion' wird allerdings nicht eine umstandslose Bestätigung der Hegelschen Textvorlage sein können, sondern immer auch den Charakter einer Kritik haben. In der Tat wird sich ergeben, daß im Vergleich mit Hegels Kategorienentwicklung einschneidende Revisionen zu gewärtigen sind. (shrink)

Dass Kunst Sinnliches zu vergeistigen und Geistiges zu versinnlichen vermag, macht ihren Wesenskern und zugleich Rätselcharakter aus. Dass dieses Rätsel immer erneut als unaufgelöst erscheint, bedeutet auch, dass eine fortdauernde Irritation von Kunst ausgeht. Das Bestürzende der Kunst ist dies, dass sie den scheinbar unversöhnlichen Gegensatz des Geistigen und Sinnlichen zugleich als versöhnt erscheinen lässt: als Ver-Sinnlichung von Ideellem. Hegels These, dass die Kunst, eben durch diese Bindung an Sinnliches, 'ihrer eigentlichen Bestimmung nach für uns ein Vergangenes' sei, erscheint so (...) gesehen problematisch. Hat die geistesgeschichtliche Entwicklung die Kunst ihrer Irrelevanz überführt im Vergleich mit den nach Hegel höheren Formen des Geistigen, der Religion und der Philosophie? Entscheidend ist die Bewertung des sinnlichen Elements – dies näher zu klären wird hier in der Konfrontation der Hegelschen These mit den Kunstdeutungen Heideggers und Adornos unternommen. (shrink)

The well-known empiricist apories of the lawfulness of nature prevent an adequate philosophical interpretation of empirical science until this day. Clarification can only be expected through an immanent refutation of the empiricist point of view. My argument is that Hume’s claim, paradigmatic for modern empiricism, is not just inconsequent, but simply contradictory: Empiricism denies that a lawlike character of nature can be substantiated. But, as is shown, anyone who claimes experience to be the basis of knowledge (as the empiricist naturally (...) does), has, in fact, always already presupposed the lawfullness of nature, i.e. has assumed the ontology of a nature lawful in itself. If lawfulness is, more closely, understood as dependency on conditions, then the functional character of the laws of nature is involved with the consequence that verification is not to be taken as a mere repetition of measurements but as clarification of the conditional structure of the physical process. Furthermore the functionality of the laws of nature also includes a statement on their invariance (relative to certain transformations) and so their lawlikeness. This throws a new light on the problem of induction. Seen in this way it is hardly surprising that the notorious neglect of the functional aspect in empiricism has led to fundamental problems with the concept of the law of nature. (shrink)

Essential for the concept of the law of nature is not only spatio-temporal universality, but also functionality in the sense of the dependency on physical conditions of natural entities. In the following it is explained in detail that just the neglect of this functional property is to be understood as the real reason for the occurrence of the Goodman paradox – with the consequence, that the behavior of things seems to be completely at the mercy of change of unique unrepeatable (...) temporal points. It is exactly this (mis-)understanding that also generated the induction problem. From the intrinsic connection between universality and functionality, however, – that is my claim – the ontological consequence of a nature results, for which lawfulness is coupled to essentially functionally defined time sequences, thereby implying a potentiality dimension of nature, too.

The study ties in with former considerations concerning the problem of phenomenal perception of higher animals. Accordingly the phenomenal character results from the adjustment of perceptions to (species-specific) behavioral dispositions under the principle of self-preservation: an emergence phenomenon provided by the constitutive system unity of perception, valuation and behavior, here named as perc-val-act-system. Thereby the subject of the behavior can be emergentistly explained as an emergent instance of the – systems-theoretically highest rank – perc-val-act-level. In terms of the principle of (...) self-preservation all sensations are submitted to a valuation. Perception thus gaining existential sense for the subject, a phenomenal-mental sense-dimension is spanned out which as such does not own physical but ideal character: Accordingly the ontological basis of this view is the lawfulness of nature, understood as the ideal essence underlying it. In virtue of this – basically Hegelian-type idealistic – conception the physical being of nature always includes the possibility of phenomenal-mental being, because of the implicit ideality of nature itself.

In this paper we argue that Socrates is a cognitivist about emotions, but then ask how the beliefs that constitute emotions can come into being, and why those beliefs seem more resistant to change through rational persuasion than other beliefs.

We argue that, if taken seriously, Kripke's view that a language for science can dispense with a negation operator is to be rejected. Part of the argument is a proof that positive logic, i.e., classical propositional logic without negation, is not categorical.

This chapter describes the potential far‐reaching consequences of contemplative higher education for the fields of science and medicine.

In this paper, we defend Socratic studies as a research programme against several recent attacks, including at least one recently published in Polis . Critics have argued that the study of Socrates, based upon evidence mostly or entirely derived from some set of Plato's dialogues, is founded upon faulty and indefensible historical or hermeneutical technique. We begin by identifying what we believe are the foundational principles of Socratic studies, as the field has been pursued in recent years, and we then (...) show how the research programme that derives from accepting these principles is not defeated by any of the most common recent criticisms of it. Specifically, we argue that challenges to sorting Plato's dialogues by date, more general challenges to historicist interpretations of Plato's dialogues, as well as recent literary criticisms of Socratic studies all fail to undermine the research programme. We conclude with some thoughts about how and why Socratic studies has proved itself a valuable and fruitful research programme. (shrink)

Impulse and momentum are basic concepts of mechanics introduced in the K to 12 curricula. Despite its basic concepts, students still have difficulties understanding the topic, especially when they are out of school due to the pandemic. After reopening the gates for face–to–face classes in the Philippines, the researchers found a significant reason to conduct a lesson study to improve teaching strategies on the topic. Lesson study is a development process wherein teachers work collaboratively to improve teachers teaching capacity. This (...) study was conducted at Plaridel National High School with 23 participants from Grade 9 Newton (Set A and B). The research was conducted in two cycles using a four – phase lesson study. The research lesson was implemented using a 4A Model lesson plan and the results were taken from the analysis of the lesson study observation sheets, along with the class proficiency level. The researchers used the following strategies to improve teaching, namely; (1) showing mastery of subject matter, (2) reviewing basic mathematical operations, (3) contextualizing the lesson, (4) allowing students to answer questions in mother tongue, (5) using collaborative activities, (6) giving rewards, and (7) applying proper time management. However, the findings still showed that both sets of students achieved beginning proficiency level. Despite the implementation of these strategies, the students still lack basic knowledge of the topic and mathematical operations, and they struggle to understand it. Thus, it is recommended to plan the lesson effectively, utilize other research instruments, and collect feedback from the students. (shrink)

Philosophers have rightly condemned lookism—that is, discrimination in favor of attractive people or against unattractive people—in education, the justice system, the workplace and elsewhere. Surprisingly, however, the almost universal preference for attractive romantic and sexual partners has rarely received serious ethical scrutiny. On its face, it’s unclear whether this is a form of discrimination we should reject or tolerate. I consider arguments for both views. On the one hand, a strong case can be made that preferring attractive partners is bad. (...) The idea is that choosing partners based on looks seems essentially similar to other objectionable forms of discrimination. (In particular, the preference for attractive partners is arguably both unfair and harmful to a significant degree.) One can try to resist this conclusion in several ways. I consider three possible replies. The first has to do with the possibility of controlling our partner preferences. The second pertains to attractiveness and “good genes”. The last attempts to link certain aspects of attractiveness to a prospective partner’s personality and values. I argue that the first two replies fail conclusively, while the third only amounts to a limited defense of a particular kind of attractiveness preference. So the idea that we should often avoid preferring attractive partners is compelling. (shrink)

The world of entrepreneurship has historically been linked with taking risks and the potential for significant rewards. However, there persists a notable gender imbalance in the entrepreneurial landscape, wherein women entrepreneurs remain a minority. Women navigating the entrepreneurial path encounter distinct challenges, setting their experiences apart from their male counterparts. In Balayan, Batangas, despite strides towards gender equality, women entrepreneurs continue to face challenges in the entrepreneurial landscape. This qualitative study delves into the experiences of 10 successful female entrepreneurs who (...) met specific criteria. Accordingly, semi-structured interviews are conducted, exploring various aspects of participants' experiences and revealing their motivations, achievements, challenges, and strategies. Thematic analysis reveals the connection between familial, community-driven, and personal motivations that drive these entrepreneurs forward. Despite facing obstacles such as financial constraints and gender biases, they prioritize financial gains and personal growth. With resilience, innovation, and dedication, these women overcome challenges and achieve success, utilizing support networks and online marketing strategies to their advantage. Recommendations include empowering women in entrepreneurship, strengthening support networks, introducing tailored financial literacy programs, and advocating against gender biases. Implement skill development initiatives and provide specialized education in online marketing. Engage in policy advocacy, celebrate success stories, and continuously research challenges and successes. Foster collaborative partnerships between businesses, educational institutions, and communities, and advocate for increased funding opportunities for sustainable growth. This research emphasizes the strength and capabilities of women entrepreneurs in Balayan, Batangas, affirming that "pink doesn't mean weak.". (shrink)

This article is a preliminary presentation of conjunctive paraconsistency, the claim that there might be non-explosive true contradictions, but contradictory propositions cannot be considered separately true. In case of true ‘p and not p’, the conjuncts must be held untrue, Simplification fails. The conjunctive approach is dual to non-adjunctive conceptions of inconsistency, informed by the idea that there might be cases in which a proposition is true and its negation is true too, but the conjunction is untrue, Adjunction fails. While (...) non-adjunctivism is a well-known option, the other view is not so much studied nowadays, but it was not unknown in the tradition, and there are some positive suggestions, in recent literature, that the position is plausible and deserves to be developed. The article compares conjunctivism, non-adjunctivism and dialetheism, then focuses on some possible justifications, costs and benefits of the conjunctive view. (shrink)

Defense of an account of intrinsic properties in terms of (what is now called) grounding rather than naturalness.

In this paper, I develop and defend a new adverbial theory of perception. I first present a semantics for direct-object perceptual reports that treats their object positions as supplying adverbial modifiers, and I show how this semantics definitively solves the many-property problem for adverbialism. My solution is distinctive in that it articulates adverbialism from within a well-established formal semantic framework and ties adverbialism to a plausible semantics for perceptual reports in English. I then go on to present adverbialism as a (...) theory of the metaphysics of perception. The metaphysics I develop treats adverbial perception as a directed activity: it is an activity with success conditions. When perception is successful, the agent bears a relation to a concrete particular, but perception need not be successful; this allows perception to be fundamentally non-relational. The result is a novel formulation of adverbialism that eliminates the need for representational contents, but also treats successful and unsuccessful perceptual events as having a fundamental common factor.

Multidimensional adjectives are ubiquitous in natural language. An adjective F is multidimensional just in case whether F applies to an object or pair of objects depends on how those objects stand with respect to multiple underlying dimensions of F-ness. Developing a semantics for multidimensional adjectives requires us to address the problem of dimensional aggregation: how do the application conditions of an adjective F in its positive and comparative forms depend on its underlying dimensions? Here we develop a semantics for multidimensional (...) adjectives that incorporates aggregation functions. We then explore an analogy between dimensional aggregation and preference aggregation, bringing results from social choice theory to bear on the number and kind of aggregation functions that are admissible in a context. These results suggest that, for any given adjective, there will often be multiple aggregation functions admissible, meaning that multidimensional comparatives are often vague. (shrink)

The paper looks at the semantics and ontology of dispositions in the light of recent work on the subject. Objections to the simple conditionals apparently entailed by disposition statements are met by replacing them with so-called 'reduction sentences' and some implications of this are explored. The usual distinction between categorical and dispositional properties is criticised and the relation between dispositions and their bases examined. Applying this discussion to two typical cases leads to the conclusion that fragility is not a real (...) property and that, while both temperature and its bases are, this does not generate any problem of overdetermination.

According to a widespread view in metaphysics and philosophy of science, all explanations involve relations of ontic dependence between the items appearing in the explanandum and the items appearing in the explanans. I argue that a family of mathematical cases, which I call “viewing-as explanations”, are incompatible with the Dependence Thesis. These cases, I claim, feature genuine explanations that aren’t supported by ontic dependence relations. Hence the thesis isn’t true in general. The first part of the paper defends this claim (...) and discusses its significance. The second part of the paper considers whether viewing-as explanations occur in the empirical sciences, focusing on the case of so-called fictional models. It’s sometimes suggested that fictional models can be explanatory even though they fail to represent actual worldly dependence relations. Whether or not such models explain, I suggest, depends on whether we think scientific explanations necessarily give information relevant to intervention and control. Finally, I argue that counterfactual approaches to explanation also have trouble accommodating viewing-as cases. (shrink)

Susan Schneider (2019) has proposed two new tests for consciousness in AI (artificial intelligence) systems, the AI Consciousness Test and the Chip Test. On their face, the two tests seem to have the virtue of proving satisfactory to a wide range of consciousness theorists holding divergent theoretical positions, rather than narrowly relying on the truth of any particular theory of consciousness. Unfortunately, both tests are undermined in having an ‘audience problem’: Those theorists with the kind of architectural worries that motivate (...) the need for such tests should, on similar grounds, doubt that the tests establish the existence of genuine consciousness in the AI in question. Nonetheless, the proposed tests constitute progress, as they could find use by some theorists holding fitting views about consciousness and perhaps in conjunction with other tests for AI consciousness.

We discuss potential biorisks from large language models (LLMs). AI assistants based on LLMs such as ChatGPT have been shown to significantly reduce barriers to entry for actors wishing to synthesize dangerous, potentially novel pathogens and chemical weapons. The harms from deploying such bioagents could be further magnified by AI-assisted misinformation. We endorse several policy responses to these dangers, including prerelease evaluations of biomedical AIs by subject-matter experts, enhanced surveillance and lab screening procedures, restrictions on AI training data, and access (...) controls on biomedical AI. We conclude with a suggestion about future research directions in bioethics. (shrink)

Prior’s puzzle is standardly taken to be the puzzle of why, given the assumption that that-clauses denote propositions, substitution of “the proposition that P” for “that P” within the complements of many propositional attitude verbs is invalid. I show that Prior’s puzzle is much more general than is ordinarily supposed. There are two variants on the substitutional form of the puzzle—a quantificational variant and a pronominal variant—and all three forms of the puzzle arise in a wide range of grammatical positions, (...) rather than merely in the complements of propositional attitude verbs. The generalized puzzle shows that a range of proposed solutions to the original puzzle fail, or are radically incomplete, and also reveals the connections between Prior’s puzzle and debates over the nature of semantic types and higher-order quantification. I go on to develop a novel, higher-order solution to the generalized form of the puzzle, and I argue that this higher-approach is superior to its first-order alternatives. (shrink)

Ramsification is a well-known method of defining theoretical terms that figures centrally in a wide range of debates in metaphysics. Prior's puzzle is the puzzle of why, given the assumption that that-clauses denote propositions, substitution of "the proposition that P" for "that P" within the complements of many propositional attitude verbs sometimes fails to preserve truth, and other times fails to preserve grammaticality. On the surface, Ramsification and Prior's puzzle appear to have little to do with each other. But Prior's (...) puzzle is much more general than is ordinarily appreciated, and Ramsification requires a solution to the generalized form of Prior's puzzle. Without such a solution, a wide range of theories will either fail to imply their Ramsey sentences, or have Ramsey sentences that are ill-formed. As a consequence, definitions of theoretical terms given using the Ramsey sentence will be either incorrect or nonsensical. I present a partial solution to the puzzle that requires making use of a neo-Davidsonian language for scientific theorizing, but the would-be Ramsifier still faces serious challenges. (shrink)

Deductive inference is usually regarded as being “tautological” or “analytical”: the information conveyed by the conclusion is contained in the information conveyed by the premises. This idea, however, clashes with the undecidability of first-order logic and with the (likely) intractability of Boolean logic. In this article, we address the problem both from the semantic and the proof-theoretical point of view. We propose a hierarchy of propositional logics that are all tractable (i.e. decidable in polynomial time), although by means of growing (...) computational resources, and converge towards classical propositional logic. The underlying claim is that this hierarchy can be used to represent increasing levels of “depth” or “informativeness” of Boolean reasoning. Special attention is paid to the most basic logic in this hierarchy, the pure “intelim logic”, which satisfies all the requirements of a natural deduction system (allowing both introduction and elimination rules for each logical operator) while admitting of a feasible (quadratic) decision procedure. We argue that this logic is “analytic” in a particularly strict sense, in that it rules out any use of “virtual information”, which is chiefly responsible for the combinatorial explosion of standard classical systems. As a result, analyticity and tractability are reconciled and growing degrees of computational complexity are associated with the depth at which the use of virtual information is allowed. (shrink)
