William Blake subtitled his Songs of Innocence and Experience ' Showing Two Contrary States of the Human Soul'. His overall vision of the human condition is one where good and evil exist interdependently and this is an idea reflected in Blake's coloured engravings of the poems, examples of which are included in this collection. This edition has comprehensive notes on the poems and an Approaches section offering commentary and activities on key themes and techniques, such as Blake's political beliefs and the role of imagery within his poetry.
