Authentication, scale-relativity, and relational kindhood.

This paper proposes a new natural kinds framework according to which kindhood is relational, dynamic, and scale-relative. Reflecting on the ontogenesis of a scientific classification, I argue that there are two distinct conceptual stages to a scientific classification: a first stage in which enough entities and relations must be authenticated for kindhood to emerge and a second in which the nature of authenticated entities and relations is investigated. The new framework is scale-relative and explains both the changing nature of the entities and relations themselves as well as the changing nature of the classifications in which they are organised.
