This article defends deliberative democracy against the problem of tacit knowledge. It has been argued that deliberative democracy gives a privileged position to linguistic communication and therefore excludes tacit forms of knowledge which cannot be expressed propositionally. This article shows how the exclusion of such knowledge presents important challenges to both proceduralist and epistemic conceptions of deliberative democracy, and how it has been taken by some to favour markets over democratic institutions. After pointing to the limitations of market alternatives, deliberative (...) democracy is defended by arguing that tacit knowledge can be brought into deliberation through the mechanism of trust in testimony. By trusting the testimony of a speaker, deliberators are able to act on knowledge even without it being explicitly expressed. The article then goes on to discuss the implications of this defence for deliberative theory, and particularly, the forms of reason which deliberative democrats must see as legitimate. (shrink)

ABSTRACT In Power Without Knowledge, Jeffrey Friedman develops a critique of technocracy and in doing so makes an epistemic case for exit over voice. He argues that a technocracy that fails to take people’s ideational heterogeneity into account is unlikely to possess the knowledge required to solve social problems, and that the alternative of “exitocracy” may, in some cases, overcome these limits. By creating the conditions under which individuals can exit from undesirable social situations, an exitocracy may allow people to (...) escape their social ills without knowing their society-wide causes or solutions. As Friedman recognizes, however, an exitocracy still requires technocratic knowledge, and this paper explores these requirements in further detail. First, it investigates the limits of exit as a solution to social problems, and the extent to which technocratic policies can be substituted for exit. Second, it considers the need for technocratic knowledge in the promotion of exit opportunities, and how this undermines Friedman’s defense of exitocracy. (shrink)
