In his 1994 collection of essays The Location of Culture, Bhabha investigates concepts such as 'hybridity' (ideas being informed by all the cultures with which they have contact) and 'mimicry' (adopting ideas from other cultures) to express a postcolonial world in which we are all 'in between' cultures. These concepts have been important to postcolonial studies—but have also informed such diverse disciplines as architecture and literature. Controversially he insists that the written word was as powerful as armed resistance in the struggle against colonizing forces, but Bhabha has also been praised for arguing that identity is not fixed, but fluctuates between different cultural influences.
