In the never-ending debate about the scope and limits of science, the hottest argument now centres on the scientific study of man himself. Can there be a science of man at all, in any comprehensive sense? Or is the idea in some way ultimately self-defeating, like that of pulling oneself up by one's own shoelaces? My purpose in this paper is not to venture a direct answer to this ticklish question, but rather to highlight one or two desirable characteristics of (...) a science which I think must inevitably be lacking in any attempt to turn the scientific spotlight upon ourselves. Whether we call the attainable residue by the name of ‘science’ is less important than that we see clearly what not to expect of it. (shrink)

In the present paper, I shall argue that quantum theory can contribute to reconciling evolutionary biology with the creation hypothesis. After giving a careful definition of the theological problem, I will, in a first step, formulate necessary conditions for the compatibility of evolutionary theory and the creation hypothesis. In a second step, I will show how quantum theory can contribute to fulfilling these conditions. More precisely, I claim that (1) quantum probabilities are best understood in terms of ontological indeterminism, but (...) (2) reflect nevertheless causal openness rather than divine indifference or arbitrariness, and (3) such a genuinely creative universe can be considered as the work of a loving Creator. I ask subsequently whether these necessary conditions are also sufficient for the compatibility of evolutionary theory and the creation hypothesis. Finally, I will show that relating evolutionary biology with theology via quantum theory could also shed some light on the nature of life. (shrink)

This paper argues against a standard view that all deterministic and conservative classical mechanical systems are time-reversible, by asking how the temporal evolution of a system modulates parametric imprecision (either ontological or epistemic). It notes that well-behaved systems (e.g. inertial motion) can possess a dynamics which is unstable enough to fail at reversing uncertainties—even though exact values are reliably reversed. A limited (but significant) source of irreversibility is thus displayed in classical mechanics, closely analogous the lack of predictability revealed by (...) unstable chaotic systems. (shrink)
