Expanding on the results of previous contributions I advance several hypotheses on the interaction of physical and semiotic processes, both in organisms and in human artifacts. I then proceed to employ these ideas to formulate a general account of evolutionary processes in terms of concrete generalization, where, in analogy with conceptual generalization, novel creations retain antecedent features as special or restricted cases. I argue the following theses: 1) the main point of intersection of physical and semiotic causation is the process (...) of regulation; 2) The broadest form of regulation is a course of actions known as modulation ; 3) Modulation is a universal means of conveyance by which a form is lifted from one supporting vehicle and re-embodied into another replica. These considerations suggest viewing biological evolution as a complex generalization of semiotic evolution. Biological reproduction is then regarded as a complex generalization of sign replication. The latter is a relatively simple affair: the embodied form is external and largely independent of its indifferent supporting medium. Biological reproduction, on the contrary, is an extremely complex dynamical process in which the embodied type is duplicated from within the medium, through the subsidiary internal replication of molecular genetic records. These ideas are developed and illustrated through comparisons between the evolution of organisms and that of human artifacts. (shrink)

Biosemiotics—a discipline in the process of becoming established as a new research enterprise—faces a double task. On the one hand it must carry out the theoretical and experimental investigation of an enormous range of semiotic phenomena relating organisms to their internal components and to other organisms (e.g., signal transduction, replication, codes, etc.). On the other hand, it must achieve a philosophical re-conceptualization and generalization of theoretical biology in light of the essential role played by semiotic notions in biological explanation and (...) modeling. This paper attempts to contribute to the second task by tracing some aspects of the historical evolution of explanatory models in biology. In so doing, a parallel can be drawn between the present status of biosemiotics and that of physics during the early decades of the last century. By following the career of the concept instrument (organon) in Aristotelian science, we revisit historical stages of the antithetical (but often complementary) roles of mechanical and teleological forms of explanation. The impact of the introduction of the organic codes in biology is seen to be somewhat analogous to that of the introduction of the quantum of action in physics. Faced with intractable empirical facts, physicists combined experimental results and bold philosophical speculation to create quantum physics—a wider, deeper framework that accommodates the new facts through a wholesale reformulation of the classical ideas. Essential to this development was the articulation of the epistemic functions of instruments, which was absent from classical physics. Similarly, the consideration of the role of instruments in biology may lead to a synthesis of Aristotelian and Kantian intuitions within a wider framework capable of joining now separate perspectives, such as Jablonka’s four-fold view of inheritance information, Barbieri’s theory of artifactual copymakers and codemakers, and recently developed models of causation based on the idea of manipulative interventions.

The course of biological evolution is regarded by many authors as an ascending path toward higher levels of variety, complexity and integration. There are similar but partly conflicting accounts of the nature and causes of this ascending course. With the aim of reaching a unified conception I start by summarily reviewing three notable examples. These are, in their latest presentations, those of Hoffmeyer and Stjernfelt 2015, Szathmáry 2015, and Lane 2015a. Comparison of their commonalities and divergences, combined with further reflections, (...) leads to the following views: 1) cooperation between preexistent traits and processes is the primary determinant in the emergence of evolutionary novelty; 2) cooperation is a triadic relation similar to semiosis ; 3) regulation, the key element of both metabolism and replication, results from the cooperation of energetic and semiotic causation; 4) conceptual generalization and concrete generalization are fruits of cooperation. Conceptual generalizations spring from the cooperation of ideas. I believe these realizations supply essential elements for a unified view of the ascent of biological evolution towards higher levels of organization. Some of these conceptions are also applicable to similar ascending trajectories through the stages of cultural and technological evolution. (shrink)

Over de bijdrage van Hegel's filosofie aan onze kennis van de wereld.

Jordan holds that art is constitutive of culture. The doctrine has thus, obviously, its roots in idealistic philosophy. Audacious, perhaps foolhardy as it may seem to some, and absurd and even perverse as it will seem to others, Jordan seeks to demonstrate that poetry "is literally the creator and legislator for the real world".

This paper attempts to explore some of the implications of the distinction between having or enjoying and knowing, between “experiencing” and science, for these implications have not always been adequately realized by those for whom the distinction is fundamental.
