Final answer:
The literary movement reflected in Rushdie's works that questions absolute meanings and emphasizes the importance of multiple perspectives is postmodernism. This movement is renowned for challenging universal truths and considering realities as social constructs shaped by language and power relations.
Step-by-step explanation:
The literary movement practiced by Rushdie that posits meanings as unstable and that holds the multiplicity of perspectives as more intriguing than a singular truth is postmodernism. This movement is characterized by its skeptical attitude towards universal explanations and its belief in the relativity of truth, focusing on the role of language and power in shaping our realities.
Postmodernism is also known for its experimental nature in literature, whereby authors create diverse literary worlds to reflect the variety of human experiences. The movement challenges the structural binaries and argues that what we perceive as reality is often a complex social construction that is influenced by individual interpretations and societal dynamics.
Additionally, postmodernism is associated with the idea that there is no single, absolute reality but rather multiple realities that coexist. It embraces constructivism, idealism, pluralism, and skepticism, which are influential in the critical analysis of knowledge and understanding. The movement stepped away from traditional philosophies, focusing on the subjective nature of human cognition and renouncing the claim of human reason as an adequate tool to uncover absolute truth.
