William Blake 
Songs of Innocence & Songs of Experience 

In this collection of poems, Blake contrasts Songs of Innocence, in which he shows how the human spirit blossoms when allowed its own free movement with Songs of Experience, in which he shows how the human spirit withers after it has been suppressed and forced to conform to rules, and doctrines. In fact, Blake was an English Dissenter and actively opposed the doctrines of the Anglican Church, which tells its members to suppress their feelings. Blake showed how he believed this was wrong through his poems in Songs of Experience.
