Ezra Pound, an American poet from the Romantic period to the Modern era, late 19th century until aprox half of the 20th; who preferred precision and vivid communication through detailed concrete images, rather than summaries or general ideas; <em>imagism</em> was one of his things, he prefferred sharp and clear language striking to the point, he prefered the use of exact words in poetry, concretion and clarity.
I don't know if there are any options, but my first guess would be - image. In his early imagist phase, Pound wanted to get rid of abstractions that were nearly the sole focus of the 19th-century romantic poetry. Instead, he aimed for pure visual images as signifiers of the world around us. He preferred simplicity as opposed to complex philosophical concepts. For example, instead of writing about nature as a source of spiritual nourishment (such as the romantic would have done), he wrote a 2-line, free-verse poem about people who are standing in the station of a metro, waiting for their train to arrive, and resembling "petals on a long, wet bough". The whole poem is an image, absolutely devoid of abstractions.
