Scientific knowledge grows at a phenomenal pace--but few books have had as lasting an impact or played as important a role in our modern world as The Mathematical Theory of Communication, published originally as a paper on communication theory more than fifty years ago. Republished in book form shortly thereafter, it has since gone through four hardcover and sixteen paperback printings. It is a revolutionary work, astounding in its foresight and contemporaneity. The University of Illinois Press is pleased and honored (...) to issue this commemorative reprinting of a classic. (shrink)

What makes a living system a living system? What kind of biological phenomenon is the phenomenon of cognition? These two questions have been frequently considered, but, in this volume, the authors consider them as concrete biological questions. Their analysis is bold and provocative, for the authors have constructed a systematic theoretical biology which attempts to define living systems not as objects of observation and description, nor even as interacting systems, but as self-contained unities whose only reference is to themselves. The (...) consequence of their investigations and of their living systems as self-making, self-referring autonomous unities, is that they discovered that the two questions have a common answer: living systems are cognitive systems, and living as a process is a process of cognition. The result of their investigations is a completely new perspective of biological (human) phenomena. During the investigations, it was found that a complete linguistic description pertaining to the ‘organization of the living’ was lacking and, in fact, was hampering the reporting of results. Hence, the authors have coined the word ‘autopoiesis’ to replace the expression ‘circular organization’. Autopoiesis conveys, by itself, the central feature of the organization of the living, which is autonomy. (shrink)

This essay has two goals. The first is to define the behavioristic study of natural events and to classify behavior. The second is to stress the importance of the concept of purpose.Given any object, relatively abstracted from its surroundings for study, the behavioristic approach consists in the examination of the output of the object and of the relations of this output to the input. By output is meant any change produced in the surroundings by the object. By input, conversely, is (...) meant any event external to the object that modifies this object in any manner. (shrink)

Three premises set the stage for a Peirce based notion of resemblance, which, as Firstness, cannot be more than vaguely distinguished from Secondnessand Thirdness. Inclusion of Firstness with, and within, Secondness and Thirdness, calls for a nonbivalent, nonlinear, context dependent mode of thinkingcharacteristic of semiosis — that is, the process by which everything is always becoming something other than what it was becoming — and at the same time itincludes linear, bivalent classical logic as a subset. Certain aspects of the (...) Dao, Buddhist philosophy, and Donald Davidson’s ‘radical interpretation’ affordadditional, and perhaps unexpected, support for the initial set of three premises.

There seems to be a relation or some sort of 'unity' between man's works and the spontaneously occurring works produced by nature such as shells, nests, horns and so on. To use Bertalanffy's term for describing common properties of objects or systems (1973), nature's forms and human forms are isomorphic. For example, efficient structures typical of shells or plants such as spirals and radii, are very common archetypes that recur throughout the whole body of humans' architecture. A spiral form can (...) be easily found in the design of the pavement of a square, the staircase of a building or the cupola of a church, while plant's radiated structures have been beautifully utilised in Gothic architecture in the form of fan vaults. Therefore a certain relation between natural and human models appears evident. But one may easily argue on the legitimacy of hypothesising this very relation. How does such visible evidence entails 'truth' or, generally, a true causal relation? This question immediately raises another one: until what extent should we trust our senses – in this specific case, sight- and, more in general, what type of knowledge do perceptions provide? In the aesthetic framework provided by the discussion on the relation between human and natural forms, this paper proposes a synthetic treatment of inferential methods, with emphasis on abduction. Being the only method of scientific enquiry that takes in serious consideration the fallible-but-creative knowledge-generation potential of perceptions, abduction allows to argue not only that there is a necessarily link between human and natural forms, but that indeed this relation is causal. In other words, human aesthetics is profoundly and primarily shaped by natural evolution. (shrink)

As this book reveals, his vision was much more complex and interesting. He hoped that machines would release people from relentless and repetitive drudgery in order to achieve more creative pursuits.

Esperimento mentale: siete Immanuel Kant, vi trovate in Australia, e ve ne state andando a passeggio. A un tratto scorgete una strana bestiola in riva al lago. Ha gli occhi di una talpa, ma sarà grande dieci volte tanto. Ha il becco di un’anatra, ma non ha le ali; e non ha piume bensì una fitta pelliccia che la fa assomigliare semmai a una lontra. La coda poi sembra quella di un castoro; e le zampe hanno dita palmate, ma con (...) artigli. Insomma, è proprio uno strano animale (ammesso che sia un animale e non una creatura degli inferi o lo scherzo di un taxidermista) nel quale certamente non vi siete mai imbattuti e di cui sicuramente non aver mai sentito parlare. Domanda: che cosa dunque state vedendo? Siete incappati in un ornitorinco. Ma attenzione: l’esperimento richiede che vi immedesimiate in Kant, e ai tempi di Kant l’ornitorinco non era ancora stato scoperto. Per meglio dire: non era ancora stato scoperto e classificato dai naturalisti europei, che ci avrebbero impiegato quasi un altro secolo prima di trovargli un posto nell’ordine sui generis dei mammiferi ovipari. Il vecchio Immanuel non ne sapeva nulla, non ne aveva il concetto; quindi voi non potete rispondere che state vedendo un ornitorinco. State vedendo quella cosa lì e basta. Il problema è cosa significhi dire che state vedendo quella cosa dato che non avete la più pallida idea di che cosa stiate vedendo. (shrink)

Theses on the semiotic study of life as presented here provide a collectively formulated set of statements on what biology needs to be focused on in order to describe life as a process based on semiosis, or sign action. An aim of the biosemiotic approach is to explain how life evolves through all varieties of forms of communication and signification (including cellular adaptive behavior, animal communication, and human intellect) and to provide tools for grounding sign theories. We introduce the concept (...) of semiotic threshold zone and analyze the concepts of semiosis, function, umwelt, and the like as the basic concepts for theoretical biology. (shrink)

The notorious but: unimpeachably corroborated case of Pavlov's mice raises, in capsule form, a variety of fascinating issues with far-reaching ramifications in several directions, but with particularly serious implications, several of which are well worth restating and pondering further (cf. Sebeóle 1977b: 192-201), both for the foundations and research methodology of contemporary semiotics.
