ABSTRACT

A heterarchy is a dynamical hierarchical system inheriting logical inconsistencies between levels. Because of these inconsistencies, it is very difficult to formalize a heterarchy as a dynamical system. Here, the essence of a heterarchy is proposed as a pair of the property of self-reference and the property of a frame problem interacting with each other. The coupling of them embodies a one-ity inheriting logical inconsistency. The property of self-reference and a frame problem are defined in terms of logical operations, and are replaced by two kinds of dynamical system, temporal dynamics and state-scale dynamics derived from the same "liar statement". A modified tent map serving as the temporal dynamics is twisted and coupled with a tent map serving as the state-scale dynamics, and this results in a discontinuous self-similar map as a dynamical system. This reveals that the state-scale and temporal dynamics attribute to the system, and shows both robust and emergent behaviors.

    • "Observational heterarchy is not only an abstract notion but also a computational model. The model is the time-state-scale re-entrant system (TSSRS) (Gunji et al., 2008; Sasai and Gunji, 2008) consisting of two perspectives: one is a logical self-reference paradox derived from an external observer (Figure 2C); the other is a frame-problem derived from an internal observer (Figure 2D). The logical self-reference paradox is a mixture of levels, whole of system (time-scale) and subsystem levels (state-scale). "

    ABSTRACT: Libet et al. (1983) revealed that brain activity precedes conscious intention. For convenience in this study, we divide brain activity into two parts: a conscious field (CF) and an unconscious field (UF). Most studies have assumed a comparator mechanism or an illusion of CF and discuss the difference of prediction and postdiction. We propose that problems to be discussed here are a twisted sense of agency between CF and UF, and another definitions of prediction and postdiction in a mediation process for the twist. This study specifically examines the definitions throughout an observational heterarchy model based on internal measurement. The nature of agency must be emergence that involves observational heterarchy. Consequently, awareness involves processes having duality in the sense that it is always open to the world (postdiction) and that it also maintains self robustly (prediction).

    • "In other words, using the terminology of Aristotelian logic, deduction brings conclusion from major premise and minor premise. Deduction is nothing more than an application of the transitive law (Sawa and Gunji, 2007, 2008). Note that major premise, minor premises, and conclusion correspond to " rule " , " case " , and " result " of terminology of Peirce, respectively. "

    ABSTRACT: We propose a dynamical model of formal logic which realizes a representation of logical inferences, deduction and induction. In addition, it also represents abduction which is classified by Peirce as the third inference following deduction and induction. The three types of inference are represented as transformations of a directed graph. The state of a relation between objects of the model fluctuates between the collective and the distinctive. In addition, the location of the relation in the sequence of the relation influences its state.

    ABSTRACT: Although life is destined to be approximately described as a self-referential form, the self-reference is invalidated and life avoids a contradiction. Since life is not a contradiction, it reveals a unity as a whole. Since it is not a self-circulation, it implements diversity and evolvability. Here we show life as invalidated self-reference by constructing a model cell driven by damaged damage. Since it is always close to destruction, it exhibits both amoebic motion and intelligent Physarum-like behavior.
