It is often assumed that democracies can make good use of the epistemic benefi ts of diversity among their citizenry, but difficult to show why this is the case. In a deliberative democracy, epistemically relevant diversity has three aspects: the diversity of opinions, values, and perspectives. Deliberative democrats generally argue for an epistemic form of Rawls' difference principle: that good deliberative practice ought to maximize deliberative inputs, whatever they are, so as to benefi t all deliberators, including the least eff (...) ective. The proper maximandum of such a principle is not the pool of reasons, but rather the availability of perspectives. Th is sort of diversity makes robustness across different perspectives the proper epistemic aim of deliberative processes. Robustness also offers a measure of success for those democratic practices of inquiry based on the deliberation of all citizens. (shrink)

Expert claims routinely “affect, combat, refute, and negate” someone or some faction or grouping of persons. When scientists proclaim the truth of Darwinism, they refute, negate, and whatnot the Christian view of the creation, and thus Christians. When research is done on racial differences, it affects, negates, and so on, those who are negatively characterized. This is why Phillip Kitcher argues that it should be banned. Some truths are too dangerous to ever inquire into, because, he reasons, even by inquiring (...) we legitimate the negation that racial distinctions already carry. Expert claims also favour or disfavour policies or decisions which have factions or persons supporting them. (shrink)
