The foregoing, it should be emphasized, are the advantages and disadvantages conventionally associated with these two forms of norms. Not all commentators are persuaded by these arguments. Carol Rose, for example, argues that, in some connections rules, by facilitating commerce, may foster "sociability" and community more than standards, and that it is nnot accicental that philanthropy flourished during historical periods dominated by rules and the related ideology of classical liberalism. By contrast, as the drafters of the UCC recognized, within a community whose members share customs and a vocabulary, standards (like "commercial reasonableness") may result in more predictable decisionmaking than crystalline rules.
