In “An introduction to phytosemiotics”, a masterwork of integration, Kalevi Kull defended Martin Krampen’s notion of phytosemiotics. In doing so, he developed the notion of vegetative semiosis. In a later work, he argued that vegetative semiosis is not a branch of semiotics, and so should not be identified with phytosemiotics. Rather, vegetative semiosis is a basic form of semiosis and the condition for animal semiosis, which in turn is the condition for cultural semiosis. All multi-celled organisms, including (...) plants, animals and humans, are characterized by vegetative semiosis. While clearly influenced by Aristotle (and Thomas Aquinas), this characterization of vegetative semiosis makes it easier to relate biosemiotics to current science, to integrate current science into biosemiotics, and thereby to greatly expand the research potential of biosemiotics.
