Abstract
Primitives are both important and unavoidable, and which set of primitives we endorse
will greatly shape our theories and how those theories provide solutions to the
problems that we take to be important. After introducing the notion of a primitive
posit, I discuss the different kinds of primitives that we might posit. Following Cowling
(2013), I distinguish between ontological and ideological primitives, and, following
Benovsky (2013) between functional and content views of primitives. I then propose
that these two distinctions cut across each other leading to four types of primitive
posits. I then argue that theoretical virtues should be taken to be meta-theoretical
ideological primitives. I close with some reflections on the global nature of comparing
sets of primitives.
