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’).
