Some Remarks on the and Epistemology of the Creation–Discovery View

Christian de Ronde∗ Federico Holik† Wim Christiaens‡

In this article we want to discuss the meaning of the violation of Bell inequalities by macroscopical systems as proposed by Diederik Aerts in several examples [1, 2, 3]. We will draw on recent research that has focused on Aerts’ contributions to the debate concerning the interpretation of the EPR-paradox and the violation of Bell inequalities by quantum entities [4]. This also requires a discussion of the so-called creation-discovery view (CD). CD makes explicit the metaphysical and epistemological principles according to which Aerts develops his analyses of the Bell inequalities. A discussion of a number of these principles will be the main goal of this presentation. We will discuss a central epistemological thesis and a central metaphysical thesis. 1. CD-epistemology. CD is a “double helix” of realism and idealism: on the one hand it adopts a strong realist stance by stating that a physical entitiy is something that exists in itself and independent of man; on the other hand it considers a real entity to be a construction that has to be understood in terms of real and possible creation-discoveries. It would appear that according to CD reality is both mind-independent and a construction. 2. CD-metaphysics. Aerts has coined the term “biomousa” to designate the central process at work in physical reality [5]. The biomousa is not just the structure of change, it is the structure of creativity. Aerts solves the problem of CD-epistemology by making the biomousa (reality) itself a construction process, i.e., a process of creation–discovery. The process of knowledge is not just metaphysical, but reality itself is a process of knowing: world views are for man what molecules were for atoms. The construction of reality carried out by man is a creation–discovery that is a special case of the construction of reality: CD-epistemology fits within CD-metaphysics. This means that it is not in its results but in the nature of its activity that CD-epistemology is realist.
