La question "combien y a-t-il d’espèces humaines" ouvre sans doute à d’interminables débats. Laissant de côté les aspects théologiques ou politiques la question, nous analysons trois dimensions du problème avec une approche fois épistémologique et historique : métaphysique, biologique technique. Sur le plan revenons aux travaux Linné Buffon pour explorer ce qui est en jeu dès lors que l’on supp...

Is the 'harm principle', famously propounded by J.S. Mill and widely adopted in bioethics, an appropriate principle to guide public health regulation? The harm principle limits liberty-limiting interventions to those instances where the person poses a significant risk of harm to others. However, much of public health regulation is not primarily directed to avert risk to others, but to safeguard...

But even in this involved field of authorship one fails to find a solution to the strange uncertainties and contradictions that made Digby, Digby. Even the "powder of sympathy" in all its implications affords no explanation. Nevertheless, Sir Kenelm could not well be ...

We model the distribution of functions implemented by non-recursive programs, similar to linear genetic programming (GP). Most functions are constants, the remainder are mostly parsimonious. The effect of ad-hoc rules on GP are described and new heuristics are proposed. Bounds on how long programs need to be before the distribution of their functionality is close to its limiting distribution ar...
