title: Biodiversity, biotechnologies and the philosophy of biology.
abstract: The thesis of this paper is that in front of the development of biotechnology and of the capacity of techniques of altering the living, there is still a very old philosophy of biology. A rapid historical view is given where the rise and diffusion of the reductionistic paradigm is presented and the connections between this paradigm and biotechnologies are traced. Curiously biotechnologies are still based on the philosophy of F. Bacon. Then the necessity of a new paradigm in biology based on the recent discoveries of complexity is underlined. It is reminded that the main discovery of science of the XX century is that we are living in a small planet of limited resources and frail equilibriums. This discovery asks for a different view of the scientific progress, more linked to the conservation of the Biosphere than to its alteration. Stability is the task for the future interactions of human-kind with nature. For this reason the relationships between stability and diversity are summarised. Finally, as the species is the main step of Biodiversity, a brief discussion of the problems posed by the altering of species barriers is presented.
