Abstract
Logic, it is often held, is primarily concerned with reasoning; and the conviction that logic and reasoning are two sides of the same coin nowadays usually equates with the conviction that logic spells out some directives for the "right" management of beliefs. In this paper I put forward an alternative view, based on seeing rules of logic rules as constitutive rules, not instructing us how to reason, but rather providing us with certain vehicles or in terms of which to reason. This also emphasizes the social nature of beliefs: they are entities forged in a social mold, formed by rules originating from social argumentative practices
