After discussing the transformation of age-old agricultural practices that has been occurring since the mid nineteenth century, and its impact on the natural environment, I identify four features of technology that point to the ambiguity of the idea of "technological progress". These are linked to the intrinsic unpredictability of technological applications and have implications for evaluating technological risks. I then show that large scale technological applications and innovations - such as expanding the practice of smallpox inoculation in the second half (...) of the eighteenth century - occur in states of 'technological exception'. In them, values are suspended and rules, limits and security norms are absent; and, in the face of risks, losses and harm to health and environment that are occasioned by technological applications introduced in the name of economical progress , normal social inhibitions become suspended in the name of furthering the values of capital and market. In addition, I show that maintaining technological exception has favored, on the one hand, the development by large corporations of antiscientific practices that threaten the moral integrity of science by impeding the proper use of the scientific method for evaluating the consequences of using technologies that are protected by patents; and, on the other hand, under the cover of ignorance, continued deterioration of the environment that threatens the very survival of the human species.

Technoscientific research, a kind of scientific research conducted within the decontextualized approach (DA), uses advanced technology to produce instruments, experimental objects, and new objects and structures, that enable us to gain knowledge of states of affairs of novel domains, especially knowledge about new possibilities of what we can do and make, with the horizons of practical, industrial, medical or military innovation, and economic growth and competition, never far removed from view. The legitimacy of technoscientific innovations can be appraised only in (...) the course of considering fully what sorts of objects technoscientific objects are: objects that embody scientific knowledge confirmed within DA; physical/chemical/biological objects, realizations of possibilities discovered in research conducted within DA, brought to realization by means of technical/experimental/instrumental interventions; and components of social/ecological systems, objects that embody the values of technological progress and (most of them) values of capital and the market. What technoscientific objects are - their powers, tendencies, sources of their being, effects on human beings and social/economic systems, how they differ from non technoscientific objects - cannot be grasped from technoscientific inquiry alone; scientific inquiry that is not reducible to that conducted within DA is also needed. The knowledge that underlies and explains the efficacy of technoscientific objects is never sufficient to grasp what sorts of object they are and could become. Science cannot be reduced to technoscience. (shrink)

This article deals with the methodological procedures employed by Johannes Kepler, particularly those used in the process of elaboration of the two first laws of planetary movements. Its aim is to show that the astronomical practice of Kepler is linked with the proposal of (physical and mathematical) hypothesis and with valuing precision in observational data, with the goal of obtaining, by means of rigorous procedures, the (mathematically expressed) regularities of planetary motions. It was only afterwards that Kepler looked for an (...) explanation of the regularities (laws) discovered, formulating the hypothesis of the magnetic action exerted by the Sun, which is located at the physical center of the system. In the new astronomy, he modifies the methodological status of astronomical hypotheses in the beginning of 17th century (present in Ptolemy, Copernicus and Brahe), promoting the passage from a mathematical descriptive astronomy to a physical-mathematical explicative astronomy.
