"5511","A Brief Introduction to N-universes","I describe in this paper the basic elements of the n-universes, a methodological tool originally introduced in Franceschi (2001) in the context of the study of Goodman's paradox. As the n-universes can be used in wide-ranging applications, such as thought experiments, I describe them from an essentially pragmatic standpoint, i.e. by describing accurately the step-by-step process which leads to a given modelisation.","http://cogprints.org/5511/","Franceschi, Paul","UNSPECIFIED"," Franceschi, Paul (2007) A Brief Introduction to N-universes.
