Standard notions of intentionality as a mental state involving representations of objects go back to the medieval Iranian philosopher Avicenna (980 – 1037). Augustine had already spoken of of “intentions” as acts of the soul, but it was Avicenna who explicitly gave what were translated to Latin as “intentions” the later standard sense of mental representations. Discussion of Avicennan “intentions” was common in the Latin scholastic tradition, but disappeared in the early modern period, only to be revived by Franz Brentano. In his 1874 work Psychology from an Empirical Standpoint, Brentano characterized intentionality as having to do with mental states that are directed toward objects that are themselves mental representations, and argued that intentionality is the defining characteristic of mind in general. Edmund Husserl later attempted to separate a logical concept of intentionality from empirical psychology, and made it a central theme of his phenomenology. Intentionality is widely discussed among analytic philosophers as well.
A main focus of Brandom’s Making It Explicit was to develop in great detail a novel concept of intentionality that is linguistic, social, and normative, rather than mental in the usual sense. Intentionality for Brandom is rooted in normative social practices and dialogue rather than psychology. Representation is treated as something to be explained, rather than as an unexplained explainer. The objects Brandomian intentionality is concerned with are not objects of mental representations, but objects of normative social practices and dialogue. Accepting Brentano’s thesis that intentionality is the defining characteristic of mind, this gives us a concept of mind that is mainly ethical, linguistic, and social (see Mind Without Mentalism).
I think the kind of hermeneutics implicitly practiced by Aristotle throughout his work was concerned with real things, but primarily as objects of normative social practices and dialogue, and only secondarily in a more direct way. Aristotle also said that intelligence comes to us “from outside”. I read him too as working with a primarily ethical, linguistic, and social notion of mind (see also Aristotelian Subjectivity). Plato’s Forms were also explicitly nonpsychological. Even Augustine’s “inner man” has nothing private about it, but rather participates in an ethical community of the spirit that tends toward universality.
An ethical-linguistic-social view of intentionality also gives us a good way of talking about all the practical, real-life concerns of human subjectivity, without the bad theoretical baggage of referring all those concerns to a supposedly sovereign individual Subject or Ego.
