All life on Earth shares the same ancestor, the most primitive form of life that arose, in still unknown circumstances, more than 3.5 billion years ago. At least this is what is commonly assumed. Astrobiologists have revisited this assumption and advanced the hypothesis of the existence of a “shadow biosphere” on Earth: a parallel tree of life whose instances, being different at the molecular level to the kind of life we are used to, would remain hidden from view. In this (...) paper, I take the emergence of the so-called shadow biosphere hypothesis and the controversial discovery of GFAJ-1, a microbe thriving in the arsenic-rich waters of Mono Lake, as an entry point to look into the strategic role of non-knowledge claims. I juxtapose the Latourian black-box, that is, those undiscussed technoscientific artifacts that are taken for granted in scientific practice, with the shadowy nature of non-knowledge claims in order to pay closer attention to the contingent, active, performative, and always social nature of the making of what is unknown. I conclude this paper by claiming that in the negotiation of what is unknown, emerging disciplines position themselves within the larger scientific community. (shrink)

The goal of this chapter is to contribute to ignorance studies by taking advantage of the pragmatist epistemology of Peirce and Dewey, which, in my view, would be an “unfinished” business without facing sundry problems raised by ignorance studies. Five typical pragmatist claims provide the framework for this chapter. They can be endorsed by other philosophies, but their conjunction is typical of pragmatism: (1) the first is Peirce’s pragmatist maxim for clarifying our ideas, where the reference to “practical bearings”, to (...) situations, conducts and contexts, is pivotal; (2) the second is pragmatism’s focus on inquiry as a norm-governed practice, rather than on mere knowledge; (3) the third idea is their “externalism”, the conviction that mind, reason and knowledge are not properties of atomic individuals but are distributed over community of inquirers or “publics” and their environment; (4) the fourth idea is that philosophy has condemned itself to skepticism when it was looking for absolute theoretical certainties; and (5) the last claim is their rejection of the fact-value dichotomy. My own general claim is that pragmatism has under-appreciated relevance for understanding the epistemology of ignorance and its social implications, and each section explores one possible dimension – semantic, epistemic, externalist, doxastic and normative – for this contribution.

The nineteenth-century strategist Carl von Clausewitz describes “fog” and “friction” as fundamental features of war. Military leverage of sophisticated information technology in the twenty-first century has improved some tactical operations but has not lifted the fog of war, in part, because the means for reducing uncertainty create new forms of it. Drawing on active duty experience with an American special operations task force in Western Iraq from 2007 to 2008, this article traces the targeting processes used to “find, fix, and (...) finish” alleged insurgents. In this case they did not clarify the political reality of Anbar province but rather reinforced a parochial worldview informed by the Naval Special Warfare community. The unit focused on the performance of “direct action” raids during a period in which “indirect action” engagement with the local population was arguably more appropriate for the strategic circumstances. The concept of “data friction”, therefore, can be understood not simply as a form of resistance within a sociotechnical system but also as a form of traction that enables practitioners to construct representations of the world that amplify their own biases.
