Abstract

Logics—that is to say logical systems—are generally conceived of as describing the logical forms of arguments as well as endorsing cer- tain principles or rules of inference specified in terms of these forms. From this perspective, a correct logic is a system which captures only (and perhaps all) of the correct principles, and good—i.e. logical— reasoning is reasoning which at the level of logical form conforms to the principles of a correct logic. In contrast, as logical particularists we reject the idea that logical validity is a property of logical forms or schema, and instead take validity to be a property of particular in- ferences. In this paper we describe and defend this radically different approach to validity, and explore the particularist understanding of the relationship between logical systems and logical reasoning.
