Freedom is certainly a theme in many of them. angston Hughes deals with freedom from the vantage point of former slaves and 20th century African-Americans. He addresses the question of freedom concerning slaves in several selections in this volume. Likewise, the question of freedom presents itself as something simultaneously tangible and intangible for blacks of the 20s and 30s (and possibly the 1940s). Like dreams, freedom is something which can be experienced internally, as in the mind, and externally, as in society.
