Semiotic Process

This paper tries to combine Peirce’s cosmology and metaphysics with current understanding in physics of the evolution of the universe, regarded as an ongoing semiotic process in a living cosmos. While the basic property of Life is viewed as an unexplainable Firstness inherent in the initial iconic state of the vacuous continuum we shall consider and exemplify two sign developing processes: (a) the transition from icon to index is considered as a symmetry breaking emergence of order actualising one among the possibilities of the iconic vacuum; (b) the transition from index to symbol, regarded as a habit formation — an adaptation of the surroundings to the order that has emerged. While the iconic state is characterized by fractal self-similarity the transitions to index and symbol are modelled by the mean field theory of second order phase transitions.
