In 'The Chimney Sweeper' of Innocence, Blake can be interpreted to criticise the view of the Church that through work and hardship, reward in the next life would be attained; this results in an acceptance of exploitation observed in the closing lines 'if all do their duty they need not fear harm.' Blake uses this poem to highlight the dangers of an innocent,... naive view, demonstrating how this allows the societal abuse of child labour.
