"In his work, Witzany takes on the difficult task of developing a new perspective, a new paradigm of living nature. This is a courageous undertaking. It involves nothing less than documenting that nature as a whole is 'linguistically structured and communicatively organized".
Thure von Uexküll, Freiburg i.Br.G.
"The philosopher Guenther Witzany has developed the fascinating theory of the main princi-ple of life phenomena: he shows us three kinds of communication, those within organisms, those within species and those between species. Revealing nature as a universal language community for the first time is a revolutionary aspect on life and on ourselves.”
Herbert Girardet, Director of Research of the World Future Council, London
"In difference to usual syntactic/semantic interpretations of observations about sign-mediated interactions of living beings (organisms), Witzany introduces consequently the pragmatic point of view in analyzing such processes. This innovative approach of the theory of communicative nature he applies on all known organismic kingdoms. Even for evolution theory new perspectives arise through Witzanys work, because the author argues sign-mediated interaction (communication) as precondition for the possibility of evolutionary processes."
Rupert Riedl, Konrad Lorenz Institute
"The selected approach is original. The character of the inquiry raised is interdisciplinary. The presentation of the scientific and especially of the biological facts is faultless. The solutions offered ultimately lead the halting discussion between biology, philosophy and theology to a new level.“
Günter Altner, University of Koblenz
"The old metaphor of the book of nature acquires an unexpected, new interpretation through Witzany's investigation in that he deciphers the text of that book as an expression of the differing forms of communication that we - as a human language community - are only capable of understanding because all living things have a common language root."
Annemarie Pieper, University of Basel
"It is not by chance that Mr. Witzany's work has received attention and positive resonance particularly among semiotics experts and proponents of psychosomatic medicine. The work does not get mired down in theoretical aspects. The 'philosophy of biology in the light of pragmatics of language' that is pursued here could have far-reaching consequences."
Franz M. Wuketits, University of Vienna
"Witzany has successfully developed a molecular biological biosemiotics based on communication theory and the philosophy of language, without having to rely on the term "semiotics."

"We can only express the hope that the author will receive the opportunity to realize his inno-vative, imaginative and self-contained framework in a contemporary philosophy of biology."
