Page "Heart of Darkness" Paragraph 42

Themes developed in the novella's later scenes include the naïveté of Europeans ( particularly women ) regarding the various forms of darkness in the Congo ; the British traders and Belgian colonialists ' abuse of the natives and man's potential for duplicity.

The symbolism in the book expands on these as a struggle between good and evil ( light and darkness ), not so much between people as in every major character's soul.
