This paper aims at a logico-mathematical analysis of the concept of chaos from the point of view of a constructivist philosophy of physics. The idea of an internal logic of chaos theory is meant as an alternative to a realist conception of chaos. A brief historical overview of the theory of dynamical systems is provided in order to situate the philosophical problem in the context of probability theory. A finitary probabilistic account of chaos amounts to the theory of measurement in (...) the line of a quantum-theoretical foundational perspective and the paper concludes on the non-classical internal logic of chaos theory. Finally, deterministic chaos points to a philosophy which asserts that chaotic systems are no less measurable than other physical systems where predictable and non–predictable phenomena intermingle in a constructive theory of measurement.

Communication Studies currently undergoes a crisis of paradigms that requires an ontological review that must begin with a debate about the conditions of possibility of every communicational phenomena. In this article we argue that semiosis offers a conceptual framework that allows for the study of communication as qualitative action. Semiosis, or the action of the sign, is here defined as a fundamental process based on perception that models the world of species, creating cognition and culture. At the core of semiosis (...) are dynamic structures that the authors have defined as ‘ontological diagrams’. The first purpose of Semiotics of Communication is to understand how these modeling systems evolve ontologically and phylogenically, producing, in the case of human culture, means of communication ever more varied and technologically advanced.

Using a couple of Paul Watzlawick's clinical cases as a starting point, the author shows how prescriptive behavioral strategies do not produce predictable effects: the theory of (nonlinear) complex systems prevents us from establishing a precise connection between a so-called psychotherapeutic act and what we consider therapeutic effects. It is precisely the consideration of the "Lorenz attractors" that thus brings us to reconsider the long psychoanalytic work as the condition for a general structural change of subjectivity: the result of this (...) work is a change of the neurotic "strange attractor.".
