Recently, oysters have been identified by the US Food and Drug Administration (USFDA) as a risky food to eat because they may or may not contain the pathogenic bacteria Vibrio parahaemolyticus. The USFDA's attempts to manage the risk manifest themselves in a “Quantitative Risk Assessment”, a report that attempts to quantify and predict the number of oyster eaters that will fall ill from Vibrio. In seeking to produce knowledge and eliminate uncertainty, the USFDA, through the use of a discourse of (...) quantification, does the opposite. Instead, we argue, documents such as risk assessments are best understood as kinds of rhetorical practice. According to this perspective, these documents are epistemologically and ontologically reductive, produce uncertainty, politicize the act of eating, and serve an ironic function. (shrink)

The aim of this paper is to articulate, discuss in detail and criticise Reichenbach's sophisticated and complex argument for scientific realism. Reichenbach's argument has two parts. The first part aims to show how there can be reasonable belief in unobservable entities, though the truth of claims about them is not given directly in experience. The second part aims to extent the argument of the first part to the case of realism about the external world, conceived of as a world of (...) independently existing entities distinct from sensations. It is argued that the success of the first part depends on a change of perspective, where unobservable entities are viewed as projective complexes vis-à-vis their observable symptoms, or effects. It is also argued that there is an essential difference between the two parts of the argument, which Reichenbach comes (somewhat reluctantly) to accept. (shrink)
