We must, therefore, make a study of mechanism; but some introduction is advisable, for cybernetics treats the subject from a new, and therefore unusual, ...

Computational functionalism [5] fails to understand the embodied and situated nature of behaviour by taking steady state functions as theoretical primitives, and by interpreting cognitive behaviour from a language-like, observer dependant framework without a naturalized normativity. Evolutionary functionalism [28, 27], on the other hand, by grounding functional normativity on historical processes fails to give an account of normative functionality based on the present causal mechanism producing behaviour. We propose an alternative autonomous dynamical framework where functionality is defined as contribution to (...) self-maintenance [15, 10, 35] and normativity as satisfaction of closure criteria. We develop this framework by a set of formal definitions in the framework of dynamical system theory and propose the hypothesis of an homeostatic-plasticity [31, 40] based general purpose value system as an internalized normative mechanism that selects between internal state trajectories to produce adaptive functionality under different environmental conditions. To test the hypothesis we develop a simulation model where lower level specifications of a control arquitecture (an homeostatic plastic DRNN) give rise (through a simulated evolutionary process) to adaptive behaviour in a foraging task where food sources can be poisonous or profitable. Analysis of the evolved agent show that plastic changes occur when the agent produces salient adaptive interactions, those plastic changes determining the adaptive strategy. The embodied and interactive adaptive functionality is dynamically analysed, illustrating the autonomous dynamical framework. (shrink)

Only those whose work and interests have led them to notice it, will have realised, in all probability, the remarkable extent to which the term organization has gained currency, or acquired new and special emphasis, throughout the entire range of scientific and sociological literature during the last ten or twenty years.In biology and bio-chemistry organization has been discussed or used as a technical term, mostly since 1930 by at least thirty well-known authors; amongst the more prominent are Huxley, Wilson, Woodger, (...) Cannon, Waddington, McDougall, Needham, Block, Hopkins and Sherrington. Under this magic term some authors refer to the physico-chemical nature of the cell or cytoplasm, and usually with special reference to selective or directive catalysis; others to the general constitution or structure of the organism and almost indistinguishable from general morphology and physiology; others to embryological development as such ; others more especially to “relations” between cells, organs and structural parts, often in an abstract sense; others refer more particularly to a hypothetical integrating and/or co-ordinating factor : a few refer to re-constitution from dissociated cells as observed in experiments with Sponges and Hydroids.

Eric Olsen argues from the fact that we once existed as fetal individuals to the conclusion that the Standard View of personal identity is mistaken. I shall establish that a similar argument focusing upon dead people opposes Olson’s favored Biological View of personal identity.

Until fairly recently a common way of doing history of science was to pick up an important strand of contemporary scientific thought and to trace its origin back to the philosophical tangle of the scientific revolution. This approach conveniently by-passed the breakdowns of once useful and pervasive theories, and neglected the long intellectual journeys along devious routes. History of science read like a success story; the pioneers who failed were neither dismissed nor excused; they were simply ignored. The historian knew (...) what he was hunting for and he was careful to limit his search to areas where his quarry was sure to be found. This method, which has been dubbed the precursor-view, stands in contrast—albeit, not in opposition—to the contextual method, which aims at a better understanding of the actual thought-processes of the early scientists. On this second view, history of science must not only account for present theories in the light of past developments, it must also assess old theories in terms of the scientist's conceptual framework, and judge them against the background of the world picture of his age. This may lead the historian down the blind alleys of the past, chasing spurious attempts at explaining the nature of physical reality, but it can clear the ground for a less anachronistic interpretation of the emergence of modern science and the actual process of discovery. History of science acts as a winnowing fork, but we cannot suppose that the discoverer himself always separated the wheat from the chaff, and we must be ever wary of equating the dream with the task.
