The comment lapidary "Bonastre JBB" does not do justice to the work of Bensaude Vincent. This makes the book insult discerning there a capacity to power such discussions "coffee trade." After all, this book is not about "the real objective science" that should instruct the ignorant masses (through an "extension"). The problem is of a different nature regarding nanotechnology and emerging technologies. Indeed, they are first and foremost the fruit of political programs, a comprehensive planning industrial type. The advanced capitalist economies seeking to redeploy their savings through new technologies and innovation. Public authorities, in partnership with industry, devote very substantial budgets. The "road maps" are being developed, which provide all the stages of development of these new technologies, from design in the laboratory for its placing on the market. Now all these technologies are expected to disembark in our society where they have all kinds of consequences, which are completely ignored. All this, and much more, that Bensaude Vincent proposes to study in this scholarly work, comprehensive and extremely well documented. The proposed approach is extremely rigorous, and focuses in turn on the concrete development programs technosciences on the dynamics at work (including economic) and impasses in terms of public debate and democratic development of these technologies. The proposed philosophical reflection and always sticks as close to the ground and draws its relevance. In short, this book is essential that seeks to understand the "nanotechnology" or "biotech" because he discerns the great philosophical and political issues that give rise (and resulting) these technological developments, and provides an excellent summary.
