Theorizing Boundary Work as Representation and Identity.

This paper introduces two theoretical approaches on symbolic boundaries that have become standard within Science and Technology Studies (STS), but which have little theoretical connections and seem to be talking about different types of boundaries. I will conceptually combine these two approaches, as well as providing a deeper explanation of what is going on when scientists draw boundaries, by utilising theoretical concepts from social psychology: social representations and identities. I will explore how the two boundary concepts can be explained through social representations and identities with an example of popular science authors' depictions of the philosopher of science, Karl Popper, and where the philosopher can become both a boundary marker that separates science from other pursuits as well as defining scientists' identity.
