Abstract

Markus Lammenranta’s essay sheds light on at least one of the reasons for this. Arguing that disagreement plays a key role not only in the Pyrrhonian but also in the Cartesian skeptical arguments, he contends that these arguments are intuitively sound and that their intuitiveness cannot be accounted for unless we assume a dialectical conception of justification. As we saw, this view maintains that one is justified in holding a belief if and only if, when appropriately challenged, one is able to defend it by offering reasons for it. Lammenranta claims that such a conception of justification should be accepted because it is rooted in our ordinary epistemic practices, and that most epistemologists fail to appreciate and explain the strength of disagreement-based skeptical arguments because of their adoption of an individualistic and nondialectical epistemology.
