 In his Philosophy of Illumination, he deals primarily with ‘apperception’ (which now replaces representation or form). He analyzes the notions of apperception and self-awareness as he explores this pre-logical mode of perception distinct from intellection. He discusses the primary awareness of the soul’s existence, its self-identity, the unmediated character of this particular type of knowledge and issues of individuation. He develops his epistemological theory by providing various arguments to demonstrate the existence of a type of knowledge that is self-evident, innate and unmediated through any type of abstraction or representation of forms, whether it be through an image, a form, a notion or an attribute of the self (Marcotte 2006).
