ABSTRACT
This chapter delves into the possibilities of a neurosemiotics of friendship by analyzing relevant research in social cognitive neuroscience. Neurosemiotics, both as a field dealing with neurobiologically based semiosic processes and as an approach for interpreting the semiosis of neuroscientific inquiry and dissemination, can help us to better understand the construct of friendship. In particular, I will discuss the claim that neural similarity predicts friendship. This postulate, analyzed as an instance of a propositional dicisign, can be true or false, depending on how prediction and friendship are interpreted. Reflections around this notion mold a neurosemiotic perspective on a fundamental aspect of our social lives.
