From molecules to human : a research on the 4th dimension of life. : Energy, material, information, meaning.

Abstract : Combining semiotics and biology, this thesis intends to give an extensive overview of the phenomena of signs in life. The approach is more than biology-inspired; it is biologically concrete: data from the biological context is directly used to support the hypothesis – semiosis exists in all levels of life: molecules, cells, organs, organisms, and species. A biosemiotics system requires the use of signs and serves the goal of self-maintenance; it is also a modularized component of a larger whole with self-organizing and self-producing properties. Representing a developmental point of view on cognition, it is argued in this work that cognitive functions – referred to as the “semiotic control” – coexist with life. With different cognitive capacities, living organisms create patterns of semiotic control; prominent traits of human cognition such as emotions and language characterize the complex forms of pattern manipulations. The sciences of semiotics and biology cannot be fully understood without each other. In this thesis, furthermore, an effort is made to connect various theoretic stances on biosemiotics to overcome the limitations of individual works. The integration between semiotics with more scientific fields is yet to be explored.
