Abstract

Many complex systems, like biologic ones, cannot be understood with reductionist and analytic methods which are based upon an aristotelian logic with two values, false and true; in the past, mathematicians and philosophers have developed alternative logics, and the philosopher Stéphane Lupasco proposed a dynamic logic named “logic of contradictory statements”, with three values, potential, actual, and T which represents a mediate position between actual state and potential state, moreover, dynamics is introduced in form of a logical movement from potential to actual, which can be reversed; last but not least, this logic presents a correlation with metaphysical concepts like involution/evolution dualism proposed by Aurobindo, implicate/explicate order proposed by the physician David Bohm, and hegelian synthesis.In this paper, we propose to describe biological systems with a general model derived from this logic, and propose that dynamics of such systems can be represented by use of (i) discontinuities which propagate, and (ii) organizing centres, so, two kinds of propagation can be involved; we propose to name actualization waves the discontinuities which propagate from centers toward periphery, and potentialization waves the ones which propagate from periphery toward centers (see fig. 1 and 2).So, it is evident that organizing centers are involved in organisation and integration of these two opposite movements in biological systems and we propose that centers are involved in autonomy and organisational closure postulated by Francisco Varela; moreover, we described interaction between two systems, a subject and an object, by use of this conception, and introduce a new concept to explain how these two systems are coupled and interact, and propose to describe this interaction as a “reduction/exchange of wave packets”, and postulate that cognitive and memorisation processes are associated with this mechanism which is controlled by organizing centres.Finally, we propose to describe these centres as composed of recursively interacting elements (see fig. 3), with topological concentric organisation composed of central elements, and peripheric elements associated to form an interface involved in resonance process between waves; and postulate that this configuration is involved in space-time organisation and regulation of dynamical process in biological systems; experimental evidences of these conception are showed, and we prove an analogy between (i) neuronal cognitive processes described with interfacial resonance between internal prerepresentation forms, and external application forms (Dehaene, 1987), and (ii) physical processes in which resonant particles are conceptualized as events which mediate interaction between observed and observing systems (Stapp, 1971).
