What is being discribed as differences between organic and cultural evolution (for example that one is Darwinian, the other, Lamarckian in character) depends on the implicit agreements made on what are analogue issues in culture and life. A special consequence of the definitions used is that opposite causal mechanisms are attributed. The development of empirical scientific theories is seen as an internal adaptation to external data. Organic evolution, however, is seen as an external selection of internal modifications. Seeing science as a special cognitive tool in the sense of evolutionary epistemology (EE) which then has to evolve according to the same principles as evolution of organic tools does, would require some notional realignments in order to level the established organismic/cultural dichotomy. Central to the approach used here is the notion of reality and adaptation. The EE declares that human categories of perception and thinking (space, time, object, causality etc.) result from evolutionary adaptation to the independent structures of an ontological reality (Campbell: “natural-selection-epistemology”). Here a “Constructivist evolutionary epistemology” (CEE) is proposed which goes one step further and considers also the category of reality itself to be a special mental concept acquired phylogenetically to immunize proven ideas under the label of “reality.” According to the CEE, the evaluation criteria for strategies and theories are the consistency with the previously and phylogenetically acquired organic and mental structures, rather than the adaptation to external data. A similar view can also be held in organic evolution where the various metabolic processes and higher strategies modify the external data according to their previously established own requirements rather than changing those requirements in adaptation to external data. Thus cognitive and scientific as well as organic evolution is an enterprise of conquest rather than of discovery and reality will lose its role as a universal legislator and evaluator. The CEE implements this thought, by considering all regularities perceived and the laws of nature derived from them as invariants of mental or sensory operators. The extension of human sense organs by means of physical measurement operators leads to the completion of classical physics if the experimental and the inborn cognitive operators commute. Otherwise non-classical (i.e. “non-human”) approaches are required such as quantum mechanics, which are based on the invariants brought about experimentally. As the set of possible experimental facilities (and therefore of new invariants) is not closed it follows that evolution of science will not end in a definitive “theory of everything” but in basically endless co-evolution between experiments and their theoretical interpretations. The same applies to organic evolution which can be considered as coevolution between genomic structures and their interpretation by the epigenetic system which itself is subject to genomic modifications. This may lead to non-stable recursive processes described here as nonlinear genetics. Some general evolutionary strategies and principles are discussed with a view to being applicable in organic evolution as well as in cultural and social evolution. Special consideration is given to the view that the need to master the physical world (mainly being done by scientific efforts) may be superseded in the long run by the need to master our social environment.

The constructivist evolutionary epistemology (CEE) has taken up the demand of modern physics that theoretical terms have to be operationalizable (i.e. the description of nature should comprise only quantities, variables or notions which are defined by means of measurement facilities or other physical processes) and extended it by the idea that operationalisation is something general which must be the constituting basis also for observational terms. This is realised by considering the regularities we perceive and which we condense to the laws of nature as the invariants of phylogenetically formed mental cognitive operators. Experimental operators (i.e. measurement facilities) can be seen as extensions of these inborn operators. This will lead to the consolidation of the classical world picture if the mental and the experimental operators involved are commutable. Otherwise there will be invariants which cannot be described in classical terms and, therefore, will require non-classical approaches such as the uncertainty principle in quantum mechanics enunciated by Heisenberg. As the development of experimental facilities will never be completed and, therefore, will continue to bring about novel invariants, evolution of science cannot converge towards what many physicists envisage as the “theory of everything” describing definitively the structure of reality (Feynman, 1965; Hawking, 1979). So, both organic and scientific evolution are entirely open and non-deterministic. When seeing also mathematical objects and structures as invariants of mental operators we must expect similar phenomena. Indeed: Just as experimental operators, though constructed entirely according to the rules of classical physics, may lead to results which cannot be described in classical terms, there are also mathematical calculuses which, though based entirely on well tested axioms, can lead to statements which cannot be proven within the context of these axioms as shown by Gödel.

It is widely understood in physics that evaluation criteria for empirical theories are determined by what is called the objective structures of an outside and real world, and on this basis, discussions ensue as to whether our scientific efforts to condense observations into theories will eventually result in a “theory of everything” (Feynman 1965, Hawking 1979, Barrow 1990, Chalmers 1982) reflecting precisely these structures. “Unless one accepts that the regularities (we perceive) are in some sense objectively real, one might as well stop doing science” (Davies 1990a). I.e., reality is seen as a prerequisite for a non arbitrary and reasonable development of theories. Without reality “anything goes” – which is the downright unacceptable in physics. On the other hand, if regularities are objective in the sense that they depend on the structures of an objective outside world, it remains unclear why mathematics which obviously does not include any information on these structures is nevertheless so helpful in describing them in such a way that purely mathematical extrapolations will lead to correct predictions. This is the old question about “the unreasonable effectiveness of mathematics in the natural sciences” (Wigner 1960), or, as Davies (1990b) put it, “why the universe is algorithmicly compressible” (i.e. why the obviously complex structure of our world can be described in so many cases by means of relatively simple mathematical formulae). This question is closely linked to why induction and, therefore, science at all, succeeds. It is difficult to avoid asking whether mathematics, as the outcome of human thinking has its own specificity which, for what ever reason, fits to the specificity of what man would see or experience. As long as this question is not comprehensively answered science may explain much – but not its own success. But how can such entirely disparate categories as perceiving and thinking be linked with each other? This question will be discussed here in the context of a new constructivist version of evolutionary approaches to epistemology (Diettrich 1991, 1993), which will lead to a revised notion of reality, as well as to some rather unexpected links between the phenomena of non-classical physics and the mathematical findings of Gödel.

The unsolved problem of induction is closely linked to “the unreasonable effectiveness of mathematics in the natural sciences” (Wigner 1960) and to the question “why the universe is algorthmicly compressible” (Davies 1960). The problem of induction is approached here by means of a constructivist version of the Evolutionary Epistemology (CEE) considering both, the perceived regularities we condense to the laws of nature and the mathematical structures we condense to axioms, as invariants of inborn cognitive and mental operators. A phylogenetic relationship between the mental operators generating the perceived and the mathematical regularities respectively may explain the high suitability of mathematical tools to extrapolate observed data. The extension of perceptional operators by means of experimental operators, i.e., by means of measurement devices) would lead to the completion of the classical world picture if both the cognitive and the physical operators are commutable in the sense of operator algebra (quantitative extensions). Otherwise the physical operators will have invariants which no longer can be described in classical terms, and, therefore, would require the formation of non-classical theories (qualitative extension), exceeding the classical world picture. The mathematical analogon would be the algorithmic extension of elementary mathematical thinking exceeding the axiomatic basis previously established according to Gödel’s incompleteness theorem. As a consequence there will be neither a definitive set of axioms in mathematics, nor will be there a definitive theory of everything in physics.

Theories and languages have in common that they aim at describing the world and the experiences made in the world. The specificity of theories is based on the fact that they code certain laws of nature. The specificity of languages is based on the fact that they code our worldview by means of their syntax. Also mathematics can be considered as theory in so far as it codes the constituting axioms. Language can achieve the objectivity postulated by analytical philosophy only if it can refer to a mathematics and logic being objective in the sense of platonism and based on a definitive set of axioms, or if the world-view concerned is definitive and based upon an objective (and therefore definitive) set of laws of nature. The first way is blocked by Goedel’s incompleteness theorem. The objectivity of the laws of nature being necessary for going the second way is questioned as well by what is called the constructivist evolutionary epistemology (CEE): the perceived patterns and regularities from which we derive the laws of nature is considered by the CEE to be invariants of inborn cognitive (sensory) operators. Then, the so called laws of nature are the result of cognitive evolution and therefore are human specific. Whether, e.g., we would identify the law of energy conservation which in physics results from the homogeneity of time, depends on the mental time-metric generator defining what is homogeneous in time. If cognitive operators are extended by means of experimental operators the result can be expressed in classical terms if both commute in the sense of operator algebra (quantitative extensions). Otherwise results would be inconsistent with the classical worldview and would require non-classical approaches such as quantum mechanics (qualitative extensions). As qualitative extensions can never be excluded from future experimental reasearch, it follows that the development of theories cannot converge towards a definitive set of laws of nature or a definitive ‘theory of everything’ describing the structure of reality. Also the structures of mathematics and logic we use have to be considered als invariants of mental operators. It turns out that the incompleteness theorem of Goedel has to be seen as analogy of the incompleteness of physical theories due to possible qualitative experimental extensions. Language, therefore, cannot be considered as an objective depiction of independently existing facts and matters but only as a theory generating propositions being consistent with our world-view. The competence of language is based on the fact that the mental mechanisms generating the ontology we use in our syntax are related to those generating our perceptions. Similar applies to the relationship between the operators generating perceived and mathematical structures enabling us to compress empirical data algorithmically (i.e. to transform them into mathematically articulated theories) and then to extrapolate them by means of the theory concerned (inductive inference). An analogue mechanism establishes our ability to compress verbal texts semantically (i.e. to reduce them to their meaning) and then to extrapolate them (i.e. to draw correct conclusions within the framework of the meaning concerned). This suggests a modified notion of meaning seing it as a linguistic analogy to theories. Similar to physical and mathematical theories also languages can be extended qualitatively particularly by means of metaphorical combinations of semantically noncompatible elements. The development of languages towards it actual richness can be seen as a process of ongoing metaphorosation. this leads to some parallels between verbal, cultural and genetic communication.

It is shown that the method of operational definition of theoretical terms applied in physics may well support constructivist ideas in cognitive sciences when extended to observational terms. This leads to unexpected results for the notion of reality, induction and for the problem why mathematics is so successful in physics. A theory of cognitive operators is proposed which are implemented somewhere in our brain and which transform certain states of our sensory apparatus into what we call perceptions in the same sense as measurement devices transform the interaction with the object into measurement results. Then, perceived regularities, as well as the laws of nature we would derive from them can be seen as invariants of the cognitive operators concerned and are by this human specific constructs rather than ontologically independent elements. (e.g., the law of energy conservation can be derived from the homogeneity of time and by this depends on our mental time metric generator). So, reality in so far it is represented by the laws of nature has no longer an independent ontological status. This is opposed to Campbell’s ‘natural selection epistemology’. From this it is shown that there holds an incompleteness theorem for physical laws similar to Gödels incompleteness theorem for mathematical axioms, i.e., there is no definitive or object ‘theory of everything’. This constructivist approaches to cognition will allow a coherent and consistent model of both cognitive and organic evolution. Whereas the classical view sees the two evolution rather dichotomously (for ex.: most scientists see cognitive evolution converging towards a definitive world picture, whereas organic evolution obviously has no specific focus (the ‘pride of creation’).
Janew C. (2014) Dialogue on alternating consciousness: From perception to infinities and back to free will. Journal of Consciousness Exploration & Research 5(4): 351–391. https://cepa.info/1059
Can we trace back consciousness, reality, awareness, and free will to a single basic structure without giving up any of them? Can the universe exist in both real and individual ways without being composed of both? This metaphysical dialogue founds consciousness and freedom of choice on the basis of a new reality concept that also includes the infinite as far as we understand it. Just the simplest distinction contains consciousness. It is not static, but a constant alternation of perspectives. From its entirety and movement, however, there arises a freedom of choice being more than reinterpreted necessity and unpredictability. Although decisions ultimately involve the whole universe, they are free in varying degrees also here and now. The unity and openness of the infinite enables the individual to be creative while this creativity directly and indirectly enters into all other individuals without impeding them. A contrary impression originates only in a narrowed awareness. But even the most conscious and free awareness can neither anticipate all decisions nor extinguish individuality. Their creativity is secured. Relevance: This article includes major constructivist concepts like operational closure and openness, individual and alternating perception, creativity, and a non-dualistic theory of everything.
In this article I show how the Dappled World Perspective can be refined in the model-based model of cognition. The very idea of modeling as replacing implies severe limitations. And this implies the Dappled World perspective at the level of models: neither humans nor robots can hope to create a single model for extensive parts of their environment. At the model level, we will always have only a patchwork of models, each very restricted in its application scope. Thus, to manage what happens in the world, we need to generate a variety of different models. Could this be done by means of a single “theory of everything” (or, at least, by means of a limited system of theories), i.e., without any ad hoc assumptions? Relevance: This model-based model of cognition is a radical version of non-dualism.
Quale A. (2008) The Issue of Reductionism. A Radical Constructivist Approach to the Philosophy of Physics. Constructivist Foundations 4(1): 43–49. https://constructivist.info/4/1/043
Purpose: To examine the role of reductionism in the theoretical development of modern physics – more specifically, in the quest for a complete unification of physical theory – from the perspective of radical constructivism (RC). Approach: Some central features of the impact of RC on philosophy of physics are pointed out: its position of scientific relativism, with important implications for the validation of scientific propositions; and the notion of sharing constructed knowledge among individual knowers and its consequences for science teaching. The issue of reductionism is then discussed with regard to (a) the hierarchical explanatory ordering of physical phenomena; (b) the idea of a “theory of everything” (TOE); and (c) some of its implications for the methodology and sociology of science. Findings: It is argued that the ontological status of the hierarchical structuring inherent in the sought-after TOE will depend on the individual knower’s epistemic position concerning the notion of truth in science. In the relativist epistemology of RC, any true/false dichotomy of theories is without meaning. A hierarchical ordering is just one of many possible strategies that may be chosen for the construction of physical theories; and such a strategy may then be considered successful only to the extent that it yields a theory that is viable. Implications: The paper serves as an illustration of the impact of RC on the ongoing search in physics for a “final theory.”
