"Knowing how we know" is the subject of this book. Its authors present a new view of cognition that has important social and ethical implications, for, they assert, the only world we humans can have is the one we create together through the actions of our coexistence. Written for a general audience as well as for students, scholars, and scientists and abundantly illustrated with examples from biology, linguistics, and new social and cultural phenomena, this revised edition includes a new afterword (...) by Dr. Varela, in which he discusses the effect the book has had in the years since its first publication.

Machines and Biology have been, since antiquity, closely related. From the zoological figures present in astronomical simulacra, through renaissance mechanical imitations of animals, through Decartes' wind pipe nerves, to present day discussions on the computer and the brain, runs a continuous thread. In fact, the very name of mechanism for an attitude of inquiry throughout the history of Biology reveals this at a philosophical level. More often than not, mechanism is mentioned in opposition to vitalism, as an assertion of the (...) validity of the objectivity principle in biology: there are no purposes in animal nature; its apparent purposefulness is similar to the purposefulness of machines. Yet, the fact that one picks machines as a set of objects comparable to living systems, deserves a closer look. What in machines makes it possible to establish such a connection? (shrink)

We propose that to understand the biological and neurophysiological processes that give rise to human mental phenomena it is necessary to consider them as behavioral relational phenomena. In particular, we propose that: a) these phenomena take place in the relational manner of living that human language constitutes, and b) that they arise as recursive operations in such behavioral domain. Accordingly, we maintain that these phenomena do not take place in the brain, nor are they the result of a unique operation (...) of a human brain, but arise with the participation of the brain as it generates the behavioral relational dynamics that constitutes language.

The answers to these two questions would have been obvious years ago: Human beings, of course, machines are instruments of human design! But now days when we speak so much of progress, science and technology as if progress, science and technology were in themselves values to be venerated, there are many people that think that machines as they become more and more complex and intelligent through human design, may in fact become alive so that they may supplant us as a (...) natural outcome of that very venerated progress and expansion of intelligence. Also many people seems to think that evolution is changing its nature so that technology is becoming the guiding force in the flow of the cosmic change in relation to us. I do not hold this view. I do not look at progress, science or technology as if they were values in themselves, nor do I think that biological or cosmic evolution is changing its nature or character. I think that the question that we human beings must face is that of what do we want to happen to us, not a question of knowledge or progress. The question that we must face is not about the relation of biology with technology, or about the relation between art and technology, nor about the relation between knowledge and reality, nor even about whether or not metadesign shapes our brains. I think that the question that we must face at this moment of our history is about our desires and about whether we want or not to be responsible of our desires. (shrink)

I do not wish to deal with all the domains in which the word time enters as if it were referring to an obvious aspect of the world or worlds that we human live. Indeed, the very fact that time can be made an issue of reflection shows us that what the word time connotes changes with the circumstances in which it is used. This situation alone, however, would not constitute a problem inviting us to enter in deep reflections if (...) we just accepted that the context defined the meaning of the word in each case. But we do not do that, and we ask the question what is time? as if we thought that the word time referred to some independent entity or dimension of nature that could be properly disclosed or described if we tried hard enough, even if we could not the final essence of it. I consider, however, that the question what is time? is adequate because it implies from the start the view that time can be properly treated as some kind of independent entity or dimension of nature. And I consider that such a view is fully inadequate because I think that all that we human beings talk about are relations that arises in our operation in language as a closed domain of recursive consensual coordinations of behaviors. Let me explain what I say with a few words about living, language, and cognition, and then answer the question what distinctions do we make or connote when we talk of time? (shrink)

Purpose: Reflecting on the propensity of our culture to think in local linear causality such as “genetic determination” by examining systems and their operation. Findings: The existence of a system is operational, and a system exists as such only as long as the operational conditions that constitute it prevail. As the observer distinguishes a system, he or she specifies with his or her operation of distinction the conditions that constitute the system. Since the adaptation between living systems and medium is (...) invariant, all that happens in their history must happen as a flow of structural congruent changes conserving their organization and adaptation. Therefore, the ontogenic phenotype is not genetically determined but arises in the process of epigenesis i.e., along a path of interactions starting from the initial structure of both system and medium, along the conservation of its living. Implications: Natural selection should not be considered as a directing pressure causing the differential survival of living systems but as its result. (shrink)

Purpose: To show how is it that that which we connote with notions of self and consciousness are configurations of sensorialities that arise in the flow of our living in recursive coordinations of doings which eventually they guide, and not entities independent of our doings. Approach: Following the consequences of our condition of structure determined systems that do not distinguish in the experience whether what they live is a perception or an illusion. Findings: That we human beings occur as relational (...) dynamics of recursive coordinations of feelings in which self and consciousness occur as configurations of sensorialities in the evanescent continuous present of the the changing flow of our living which they also guide. Practical Implications: Thinking, acting and reflecting in the awareness that self and consciousness are not physical entities or properties. (shrink)

Der Mensch ist fähig zu erkennen. Diese Fähigkeit setzt allerdings seine bio logische Integrität (Ganzheit, Unversehrtheit) voraus. Der Mensch kann außerdem erkennen, daß er erkennt. Erkennen (Kognition) als basale psychologische und somit biologische Funktion steuert seine Handhabung der Welt, und Wissen gibt seinen Handlungen Sicherheit. Objektives Wissen scheint möglich, und die Welt erscheint dadurch planvoll und vorhersagbar. Und doch ist Wissen als Erfahrung etwas Persönliches und Privates, das nicht übertragen werden kann. Das, was man für übertragbar hält, nämlich objektives Wissen, (...) muß immer durch den Hörer geschaffen werden: Der Hörer versteht nur dann, und objektives Wissen erscheint nur dann übertragbar, wenn der Hörer zu verstehen (vor)bereit(et) ist. Kognition als biologische Funktion besteht darin, daß sich die Antwort auf die Frage Was ist Kognition? aus dem Verständnis des Erkennens bzw. des Erkennenden aufgrund der Fähigkeit des letzteren zu erkennen ergeben muß. Eben darin besteht meme Arbeit. Epistemologie Der zentrale Anspruch der Wissenschaft ist Objektivität: sie [die Wissenschaft] ist bestrebt, mit Hilfe einer wohldefinierten Methodologie Aussagen über die Welt zu machen. Gerade in der Basis dieses Anspruches liegt jedoch ihre Schwäche: die apriorische Annahme, daß objektives Wissen eine Beschreibung dessen darstellt, was man weiß. Eine solche Annahme erfordert die Klärung der Fragen Worin be steht Erkennen bzw. Wissen? und Wie erkennen und wissen wir? Biologie a) Das größte Hindernis für das Verständnis der Organisation des Lebendigen liegt darin, daß es nicht möglich ist, sie durch eine Aufzählung ihrer Eigen schaften zu erklären. Sie muß vielmehr als Einheit verstanden werden. (shrink)

La noción del Tao constituye una invitación a un vivir en el bien-estar psíquico y corporal, a un vivir sin esfuerzo en la unidad de toda la existencia en el hacer que surge del ver el presente cuando no hay prejuicio o expectativa. Como tal, la noción del Tao ha llevado a muchas personas a la reflexión y a la acción que busca encontrar o revelar la naturaleza de ese vivir en los ámbitos de la filosofía, la mística, y la (...) religión. ¿Con qué nos conecta ese vivir?, ¿con lo divino o lo biológico? Pensamos que el vivir al que la noción del Tao nos invita es el vivir fundamental del vivir del ser vivo en su naturaleza biológica que se da en el existir en un presente cambiante continuo. En nosotros, los seres humanos, ese vivir ocurre como un vivir en el lenguajear sin enajenarse en el explicar, vivir que surge cuando se vive en la ampliación del ver en el desapego que es la biología del amar. Por esto el camino del Tao es el camino del amar, y el camino del amar es la biología del Tao. (shrink)

The phenomenon of size constancy is defined as the apparent perceptual invariance of the linear dimensions of a seen object as this approaches the eye or recedes from it. It has been interpreted as resulting from the application by the brain of a size correction, made possible by the subject's apprehension of distance cues present in the image. We present several observations which, by dissociating accommodation from distance of the seen object and by suppressing the optic effects of accommodation on (...) the visual image itself, show that this interpretation is incorrect, and that in fact the size correction of the visual image is a function of the central effort of accommodation, not of the distance of the seen object.

Context: At the conference “The Ethical Meaning of Francisco Varela’s Thought,” which took place on 28 May 2011 in Sassari, Italy, Humberto Maturana, Michel Bitbol, and Pier Luigi Luisi participated in two discussions. Purpose: In this edited transcription of the discussions, the participants talk about several aspects of autopoiesis, the observer, ontology, making distinctions and distinguishing different domains, perception and illusion, and transcendence. Results: The discussions shed light on how constructivist concepts are perceived by individual authors. Concepts such as “transcendence” (...) and “objectivity” are understood in different ways. Constructivist content: The concepts discussed are highly relevant for constructivist approaches. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Paradox of Education:A ConversationHumberto R. Maturana and Bernhard PoerksenResponsibility of the TeacherPoerksen: Immanuel Kant writes in his essay Über Pädagogik that the wide field of education is governed by a fundamental paradox. On the one hand, we want free and self-determined individuals to leave our schools; on the other, we impose a syllabus on the future individuals, force them to attend schools, punish their failures, and persecute their (...) noncompliance. There is, if we follow Kant, an inescapable relationship of tension between the goals and the means of educational efforts: They contradict each other. Would you agree?Maturana: No. Education, the commentary of an observer, is the process of transformation resulting from the co-existence with adults. We become the adults we have been living with. This means: If freedom and self-determined thinking are the goals of educational activity, then we have to live together in a way that is supported by the mutual respect for the autonomy of the other. In my view, the paradox formulated by Kant does not exist at all. The way of life, the manner of living together, shapes and transforms people. If you want to teach autonomy and reflection, you cannot use force as a method but must create an open space for communal reflection and action. There must be no contradiction between goals and means.Poerksen: Surely, there must also be constraints? It must be laid down when everybody has to be present, what the task is, who the teacher is, who has authority.Maturana: Compulsion will emerge if the teachers do not succeed in presenting their material in a thrilling way and in making school an attractive place of being together. Their failure will lead to force.Poerksen: The teacher is totally responsible for everything that may happen in school. Is this not an exaggerated claim?Maturana: No. If a teacher behaves respectfully, if he does not intimidate his pupils, if he listens, encourages cooperation and reflection, then a special form of interaction will emerge. The way of living practiced by the teacher, including the goals of teaching, will be the source of profitable learning for the pupils. This also implies that three questions and tasks must be sorted out cooperatively in education. First it seems necessary to me to debate the educational ideal to be chosen—what should the future adults be like when leaving the school one day? Should they be democratically minded and responsibly acting citizens? Or are they to be authoritarian and commandeering hierarchs, lords who feel superior to everyone else? It is then necessary to anchor a way of life in the school that permits acting and thinking according to that ideal. Finally, there is the essential task of preparing the teachers for their job in such a [End Page 25] way as to do justice to the desired goals—to enable them to live what they have to achieve.Poerksen: This would mean that teaching has nothing to do with the stepwise elimination of ignorance, as is commonly thought. The transmission of knowledge is secondary. The primary requirement is a way of life that corresponds with one's ideals, a particular form of living together, out of which the material topics will arise in due course.Maturana: Exactly. The children do not learn mathematics in school; they learn how to live together with a mathematics teacher. Perhaps they will one day carry on this enjoyable and exciting kind of being together independently—and become mathematics teachers or mathematicians themselves. Teachers do not simply transmit some content; they acquaint their pupils with a way of living. In the process, the rules of arithmetic, the laws of physics, or the grammar of a language will be acquired. My claim is: Pupils learn teachers.Poerksen: What about children who systematically refuse to cooperate? What is to be done with them? The classical answer is, of course: bad marks, relegation, exclusion from the winning circles.Maturana: The so-called difficult children about whom teachers keep complaining often only struggle to be seen and accepted, while the whole world expects them to behave in a calculable manner and to adapt to strange demands.

An organism is a harmonious closed network of molecular and cellular interactions that produce molecular and cellular transformations and replacements in the continuous realization of its molecular autopoiesis. The processes that we call immunity are dynamics of recovery of that harmony when it is lost as a result of the appearance or intrusion of molecules that do not normally pertain to it, which destroy that harmony, giving rise to what is lived as a disease.
