"Innocence" and "Experience" are definitions of consciousness that rethink Milton's existential-mythic states of "Paradise" and the "Fall." Blake's categories are modes of perception that tend to coordinate with a chronology that would become standard in Romanticism: childhood is a state of protected innocence rather than original sin, but not immune to the fallen world and its institutions. This world sometimes impinges on childhood itself, and in any event becomes known through "experience," a state of being marked by the loss of childhood vitality, by fear and inhibition, by social and political corruption, and by the manifold oppression of Church, State, and the ruling classes.
