This paper aims to map the different theoretical options related to the Precautionary Principle (PP). Great part of the literature on it can be systematized by answering to three different questions: is there a basic structure in the PP? If so, in which interpretation of the PP does this structure express itself? Finally, are its damage or knowledge conditions fixed or adjustable? The first question separates realist from non-realist approaches. The second question allows us to discriminate monist, dualist, or pluralist (...) positions in relation to the three interpretations of the PP: decision rule, procedural requirement, or epistemic rule. Finally, the third question distinguishes rigid from non-rigid formulations of the principle. Based on this mapping, one can not only navigate through the different formulations of the PP present both in official documents and in specialized literature, but also deflect some of its common objections, and understand Hans Jonas’ eventual connection with PP. Notwithstanding, this mapping does not capture other important themes attached to PP, which motivates a final distinction between narrow and broader forms of PP. (shrink)

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.

My aim in this paper is to rebut objections that have been made of the account of the various roles for values in scientific activities that I have developed, initially in my book Is Science Value Free?, in response to criticizing the proposal that science is value free. Specifically I respond to objections that my account does not recognize the significance of basic science, and that my defense of the ideal of impartiality cannot be sustained.

Este artigo explora alguns aspectos da noção de "mundo da vida" apresentada por Edmund Husserl, de modo a contribuir com o desenvolvimento do modelo da interação entre ciência e valores proposto por Hugh Lacey. Em particular, almeja-se mostrar a fundação das estratégias descontextualizadoras de pesquisa científica nas experiências concretas, compostas de diversos níveis de operações intencionais.
