ABSTRACT
This chapter seeks to elucidate the distinctive nature of the rational impression on its own terms, asking precisely what it means for the Stoics to define logikē phantasia as an impression whose content is expressible in language. At the heart of Stoic philosophy of mind is the rational impression. As it happens, the Stoics think that the mind resides in the heart, but this is not what makes the Stoic account interesting; seating the mind in the heart is a commonplace for the time. The Stoics are well known for their robust corporealism: they say that only bodies exist, or are, and they cast a large swath of reality as corporeal. The soul's corporeality can also be considered from a metaphysical standpoint, in terms of the so-called Stoic categories: substrate, qualified individual, disposed individual, and relatively disposed individual.
