Hegel also argues strongly against the epistemological emphasis of modern philosophy from Descartes through Kant, which he describes as having to first establish the nature and criteria of knowledge prior to actually knowing anything, because this would imply an infinite regress, a foundationalism that Hegel maintains is self-contradictory and impossible. Rather, he maintains, we must examine actual knowing as it occurs in real knowledge processes. This is why Hegel uses the term "phenomenology". "Phenomenology" comes from the Greek word for "to appear", and the phenomenology of mind is thus the study of how consciousness or mind appears to itself.

In Hegel's dynamic system, it is the study of the successive appearances of the mind to itself, because on examination each one dissolves into a later, more comprehensive and integrated form or structure of mind.
