We show the presence of genuine quantum structures in human language. The neo-Darwinian evolutionary scheme is founded on a probability structure that satisfies the Kolmogorovian axioms, and as a consequence cannot incorporate quantum-like evolutionary change. In earlier research we revealed quantum structures in processes taking place in conceptual space. We argue that the presence of quantum structures in language and the earlier detected quantum structures in conceptual change make the neoDarwinian evolutionary scheme strictly too limited for Evolutionary Epistemology. We sketch how we believe that evolution in a more general way should be implemented in epistemology and conceptual change, but also in biology, and how this view would lead to another relation between both biology and epistemology.Keywords: quantum, evolution, language, Bell's inequalities, context
IntroductionIn this article we will demonstrate the presence of quantum structures in language by proving the violation of Bell's inequalities 2 . Apart from any specific philosophical theory about language, the presence of quantum structures in language is an interesting finding, particularly to the community of scientists who study the structure of language, and also to those who investigate the working of the human mind, language being one of the mind's major products. In addition to this first-order motivation -as one could call it -, the search for quantum structures in language was equally well guided by the aim of elaborating the global worldviews construction program, which is the main theme of research in the Leo Apostel Centre (CLEA) (Aerts, Apostel, De Moor et al. 1995;Apostel 1995). It is through its relevance for the global worldviews construction program that the material presented in this article becomes relevant for Evolutionary Epistemology (EE), certainly in the broad interpretation that EE was given at the conference where we presented the material of this article. The Stanford Encyclopaedia of Philosophy defines EE thus:EE is the attempt to address questions in the theory of knowledge from an evolutionary point of view. It involves, in part, employing models and metaphors drawn from evolutionary biology in the attempt to characterise and resolve issues arising in epistemology and conceptual change. There are two interrelated but distinct programs which go by the name EE. One focuses on the development of cognitive mechanisms in animals and humans. This involves as straightforward extension of the biological theory of evolution to those aspects or traits of animals which are biological substrates of cognitive activity, e.g. their brains, sensory systems, motor systems, etc. This program has been labelled EEM. The other program attempts to account for the evolution of ideas, scientific theories, epistemic norms and culture in general by using models and metaphors drawn from evolutionary biology, and it has been labelled EET. EE is sometimes given a narrow meaning, according to which it is said to attempt to model epistemolo...
