|Prehistory=In modern times philosophers have held a variety of views about how best to express the structure and content of scientific theories.[[CiteRef::Winther (2016)]]
The pragmatic view rejects a purely formal characterization of scientific theories entirely, and supposes that a theory necessarily consists of sentences, models, problems, standards, skills, practices, including such things as analogies, metaphors, and natural kinds, with its full characterization necessarily including elements that cannot be formalized.[[CiteRef::Mormann (2008)]][[CiteRef::Winther (2016)]] Proponents of the pragmatic view include [[Nancy Cartwright]], [[Ian Hacking]], [[Philip Kitcher]], and [[Helen Longino]].
|History=[[Theory (Barseghyan-2015)|The original definition]] of ''theory'' was proposed by Barseghyan in 2015. It defined a theory as any set of propositions that attempt to describe something.[[CiteRef::Barseghyan (2015)]] As such, this definition excluded normative propositions. In early 2017, it was replaced by [[Theory (Sebastien-2016)|the definition]] suggested by Sebastien in 2016.
