A scientific community cannot practice its trade without some set of received beliefs. These beliefs form the foundation of the "educational initiation that prepares and licenses the student for professional practice". The nature of the "rigorous and rigid" preparation helps ensure that the received beliefs are firmly fixed in the student's mind. Scientists take great pains to defend the assumption that scientists know what the world is like...To this end, "normal science" will often suppress novelties which undermine its foundations. Research (...) is therefore not about discovering the unknown, but rather "a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education". (shrink)

Thomas S. Kuhn's classic book is now available with a new index.

The first full-scale history of cognitive science, this work addresses a central issue: What is the nature of knowledge?

What is life? For four centuries, it has been believed that the only possible scientific approach to this question proceeds from the Cartesian metaphor -- organism as machine. Therefore, organisms are to be studied and characterized the same way "machines" are; the same way any inorganic system is. Robert Rosen argues that such a view is neither necessary nor sufficient to answer the question. He asserts that life is not a specialization of mechanism, but rather a sweeping generalization of it. (...) Above all, Rosen argues that renouncing mechanism does not mean abandoning science. A radical alternative is proposed, drawn equally from experience in biology, physics, and mathematics; an alternative which draws attention to a new class of complex systems, which are radically different from mechanism.

La science classique s'est trouvée associée à un désenchantement du monde. C'est la leçon que Jacques Monod entendait tirer des progrès de la biologie : "L'ancienne alliance est rompue. L'homme sait enfin qu'il est seul dans l'immensité indifférente de l'Univers d'où il a émergé par hasard." Notre science n'est plus ce savoir classique, nous pouvons déchiffrer le récit d'une "nouvelle alliance". Loin de l'exclure du monde qu'elle décrit, la science retrouve comme un problème l'appartenance de l'homme à ce monde. Les (...) théories scientifiques ne peuvent plus supposer la possibilité d'un savoir omniscient : nous lisons, jusque dans leurs principes, les traces d'une activité d'exploration au sein d'une nature en évolution.

The first edition of this book profoundly challenged and divided students of philosophy, sociology, and the history of science when it was published in 1976. In this second edition, Bloor responds in a substantial new Afterword to the heated debates engendered by his book.

Hilary Putnam deals in this book with some of the most fundamental persistent problems in philosophy: the nature of truth, knowledge and rationality. His aim is to break down the fixed categories of thought which have always appeared to define and constrain the permissible solutions to these problems.

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)

But to explain. Dissipation inspires the wrath of the moralist and the envy of most others; for the physicist, however, it is merely faintly depressing. We call something dissipative if it looses energy to waste-heat. (Technically: if volume in the phase space is not conserved.) The famous Second Law of Thermodynamics amounts to saying that, if something is isolated from the rest of the world, it will dissipate all the free energy it has. Equivalently, it maximizes its entropy. Thermal equilibrium (...) is the state of maximum entropy. (shrink)

Embodiment, Vesey maintains, is the term applied to our experience of an unmediated movement of our body and an unmediated awareness within perceptual experience. Vesey argues for embodiment as the most satisfying explanation of the mind-body relationship chiefly by arguing against substance dualism as presented by the Local Sign theory of sensation and the Ideo-motor theory of bodily movement. The former is deficient because it rests on the false empirical assumption that all perceptual capacities are learned; the latter is inadequate (...) for more complex reasons, the development of which leads Vesey through his own theory of perception and movement. Vesey's own theory rests on contrast between causal, substance dualism and his own favored, non-causal, subject-object duality, which avoids an absolute dualism because of the internal relatedness of its key terms from the outset. The first half of the book presents a concise review and criticism of current non-dualistic views of the mind-body relation other than that of embodiment; here Vesey has a brief and somewhat unsatisfying skirmish with double aspect and identity theories.—E.
