As a consequence of human interference in modern times, language has gone to the extreme of deviating from the world to which it gave the original name. As a poet, Robert Hass tries to restore trust in language with his linguistic skepticism, reexamining the emergence and evolution of language in its natural history, and treating human involvement in it as a result of the dynamism between man as an organic creature and his living environment. Hass’ s concerns about ways of seeing the world and ethics of perception have significantly influenced his aesthetics. The relation of his poetry to the world is neither mapping nor projecting but somewhere in between, revealing and creating the world between mimesis and fiction. Meanwhile, the mirroring capacity and political representation of language are fused in Hass’ s poetry to express his ethics of perceptive experience and his politics of romantic pragmatism.
