In the reception of Josef Mitterer’s writings up to now, there are two predominant types of motifs: the radical constructivist background of his philosophy and the ontological and epistemological foundations and consequences of non-dualism. The critics are focused rather on some problematic consequences of non-dualism, ranging from the problem of infinite regress up to the thesis assuming that Mitterer’s philosophy presupposes a world reduced to descriptions. However, these two types of readings are founded on dualizing assumptions which are not coherent with non-dualism. \\Thus, in the present paper I interpret non-dualism in the frame of non-dual-ism, based on non-dualizing assumptions. I argue that non-dualism is a rhetorical project resulting in far-reaching consequences in the field of academic and scientific debates, poetics and practice of negotiations and deliberations, as well as in ordinary discourse. Non-dualism fulfills Richard Rorty’s dream of culture as a never-ending conversation in which the argument of power is successfully replaced by the power of argument. Mitterer makes transparent the rhetorical techniques performed in the dualizing discourse (not only in situations of conflict) in order to present an alternative – the non-dualizing mode of discourse. Mitterer’s philosophy – reread in the context of Rorty’s pragmatism, Foucault’s conception of discourses, Perelman’s new rhetoric – offers the new vocabulary (in Rorty’s meaning) which may change the practice of speaking

Key words: non-dualizing mode of speaking, description “so far” / “from now on, ” constructivism, rhetoric, discourse.

This paper considers communication in terms of inference about the behaviour of others (and our own behaviour). It is based on the premise that our sensations are largely generated by other agents like ourselves. This means, we are trying to infer how our sensations are caused by others, while they are trying to infer our behaviour: for example, in the dialogue between two speakers. We suggest that the infinite regress induced by modelling another agent – who is modelling you – can be finessed if you both possess the same model. In other words, the sensations caused by others and oneself are generated by the same process. This leads to a view of communication based upon a narrative that is shared by agents who are exchanging sensory signals. Crucially, this narrative transcends agency – and simply involves intermittently attending to and attenuating sensory input. Attending to sensations enables the shared narrative to predict the sensations generated by another (i.e. to listen), while attenuating sensory input enables one to articulate the narrative (i.e. to speak). This produces a reciprocal exchange of sensory signals that, formally, induces a generalised synchrony between internal (neuronal) brain states generating predictions in both agents. We develop the arguments behind this perspective, using an active (Bayesian) inference framework and offer some simulations (of birdsong) as proof of principle.

Key words: communication, theory of mind, active inference, predictive coding, attention, sensory attenuation, bayesian, generalised synchrony.

This article analyses the work of Robert Rosen on an interpretation of metabolic networks that he called (M, R) systems. His main contribution was an attempt to prove that metabolic closure (or metabolic circularity) could be explained in purely formal terms, but his work remains very obscure and we try to clarify his line of thought. In particular, we clarify the algebraic formulation of (M, R) systems in terms of mappings and sets of mappings, which is grounded in the metaphor of metabolism as a mathematical mapping. We define Rosen’s central result as the mathematical expression in which metabolism appears as a mapping f that is the solution to a fixed-point functional equation. Crucially, our analysis reveals the nature of the mapping, and shows that to have a solution the set of admissible functions representing a metabolism must be drastically smaller than Rosen’s own analysis suggested that it needed to be. For the first time, we provide a mathematical example of an (M, R) system with organizational invariance, and we analyse a minimal (three-step) autocatalytic set in the context of (M, R) systems. In addition, by extending Rosen’s construction, we show how one might generate self-referential objects f with the remarkable property f(f)=f, where f acts in turn as function, argument and result. We conclude that Rosen’s insight, although not yet in an easily workable form, represents a valuable tool for understanding metabolic networks.

Context: Non-dualism suggests a new way of utilizing language without the assumption of categorically extralinguistic objects denoted by language. Problem: What is the innovative potential, what is the special value of non-dualism for science? Is non-dualism a fruitful conceptual revision or just a philosophical thought experiment with no or little significance for science? Method: We provide a concise introduction to non-dualism’s central new proposals and an overview of the papers. Results: Fourteen contributors show how this way of thinking and speaking can be operationalized creatively, but also address some of its boundaries. Implications: Since not all of the aspects and problems highlighted for discussion in the original Call for Papers were answered satisfactorily, further research is necessary. For example, research is needed on the relationship between dualism’s distinction between object language and metalanguage on the one hand and non-dualism’s distinction between descriptions so far and descriptions from now on on the other; or on the infinite regress allegations by non-dualism against dualism. Constructivist content: Some authors show that non-dualist thinking is anti-essentialist, in a similar way as constructivist thinking. Some also show that comparable questions arise; for example, the question of whether non-dualism denies the material world (containing extralinguistic objects).

Context: The short history of the reception of the philosophy of non-dualism in science is a history of misunderstandings and cursory reception – the latter especially concerns Mitterer’s main work Das Jenseits der Philosophie (The Beyond of Philosophy, which still has not been translated into English). Non-dualism so far is mostly seen either as a kind of constructivism replacing the rhetoric of “construction” with a rhetoric of “description” or as an overall philosophical critique of the use of dualisms, dichotomies or polarities in epistemological contexts. The core arguments of non-dualism are often completely ignored. This paper wishes to discuss them precisely and draw some conclusions. Approach: Close critical reading of Mitterer’s texts, trying to avoid as many translation gaps as possible. Findings: Non-dualism reveals the infinite regress of classical philosophy of language: the categorical differentiation between language and the world leads to a systematic contradiction. While non-dualism also helps to deconstruct the pretension to speak “about reality” or to claim that “in fact” something is the case in everyday life, non-dualism refrains from giving satisfying answers to the great questions of mankind in the “metaphysical” context: questions of starting points/origins, meanings, causes, and the (implicitness of the) time arrow. Benefits: The intention of this paper is to stimulate a broader discussion – so far limited by language – extending it beyond German and Polish scientific circles.

Key words: language/object, realism-constructivism controversy, Mitterer’s indication of the object (“Objektangabe”), Wittgenstein’s aspect seeing (“Aspektsehen”), arrow of time

Open peer commentary on the target article “From Objects to Processes: A Proposal to Rewrite Radical Constructivism” by Siegfried J. Schmidt. Upshot: This commentary asks if Schmidt’s latest process-orientated philosophy is based on a vicious infinite regress argument. The commentator uses recent literature on the distinction of vicious and benign infinite regresses (from Claude Gratton and Nicholas Rescher) and tries to show that – taken verbatim – there is a serious logical problem in Schmidt’s argumentation.

Context: Is non-dualist epistemology, based on the unity of descriptions and objects, logically consistent? Problem: What is the status of the infinite regresses that the non-dualist Josef Mitterer, in his book The Beyond of Philosophy, censures in dualist thought? Their academic discussion is still in its infancy. Method: An attempt to reconstruct and differentiate Mitterer’s infinite regress accusations against dualism (originating from the 1970s) with today’s means and distinctions. Results: A weak and a strong linguistic principle are presented (non-dualism being subsumed under the strong linguistic principle), which are defined as such depending on whether the infinite regresses of dualism are interpreted as benign or as vicious. Implications: Further penetrating investigation of the infinite regresses highlighted by Mitterer is of crucial importance because these regresses have not yet been discussed and classified in relevant current publications on infinite regress arguments by authors such as Rescher or Gratton. Such proper classification is indispensable, however, if the value of the non-dualist alternative to, and its critique of, dualist thought is to be assessed adequately.
