Die strikte Trennung von Objekt- und Metasprache wird aufgrund des vorgeschlagenen Verfahrens zur Vermeidung von Antinomien nicht nur überflüssig, sondern inakzeptabel. Andererseits führt die Vereinigung eines formalen Systems mit seiner Metatheorie zum Gödelschen Unvollständigkeitsproblem. Daß dieses nicht durch Modifizierungen des Beweisbarkeitsbegriffs eliminierbar ist, findet hier, wie gezeigt wird, seine Erklärung darin, daß der zugrundeliegende Sachverhalt tatsächlich nicht beweistheoretischer, sondern sprachlicher Natur ist: Reflexive Unbeweisbarkeitsaussagen sind stets unbeweisbar und wahr zugleich. Damit wird Gödels Problem nun in anderer Weise eliminierbar; durch Beseitigung eben jener reflexiven Unbeweisbarkeitsaussagen

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 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.

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.

A Criticism misjudging itself too. On the Deficiency of Reflection in Formal Explications. The criticism formulated by L. B. Puntel concerning the theory of dialectic proposed by the author is rejected. Puntel's attempt at explicating predication by means of (second order) predicate logic fails: It misjudges predication being already presupposed for the possibility of predicate logic, thus belonging to the transcendental conditions of formal predicate logic, so that predication itself cannot be further explicated by means of such logic. What is in fact criticized by Puntel is something like an artefact of formalization. The unreflected application of formal logic here generates problems instead of solving them

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).

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.
