On a more specific literary interpretation:

Production and materialism:

For Marx, what sets humans apart from animals is history. We are real individuals, living with real material reality (which reflects the 18th primer). Furthermore, men are distinguished from animals in consciousness—when they begin to produce substances to live for themselves. We, humans, are distinguished because we produce ourselves: 1- in way we keep ourselves alive; 2-through sex, literally reproducing ourselves.

[side note: in terms of animal studies, these views are questionable. Animals have consciousness, produce means to live for themselves, keep themselves alive, and have sex to reproduce themselves. The argument might be made that Marxism can be applied to animals by analyzing animal’s base and superstructures since animals have rituals and “ideology” in a way, especially the more sophisticated primates and mammals]

Marx starts from material history—not ideas. [For example, texts, like everything else, are produced and determined by history and context, not freely shaped by ideas of an author. Those ideas an author has are shaped by his/her material reality and history]. Even the materiality of body affects the manner in which you think. If your body is being tortured, that will shape the way you think. If you are wearing certain clothing—fashionable clothing, tight clothing, comfortable clothing—will shape the way you think].

In terms of literary criticism: Some critics will look at author as if he/she didn’t exist in a certain historical moment. The critic examines the text in an idealist manner or non-materialist manner. Idealism—a way of thinking that divorces consciousness from history; 1-in the realm of which you fall down, scrape your knee, eat dinner, all of material history; 2- in the realm in which you think about this things (in 1) or imagine these things. Idealism believes these two points are separate.

Marxist critic believes, however, that an author is a product of his time and produced in a certain historical moment. The author, furthermore, is a producer of his time. An author takes raw materials (language, old texts, form, style, etc.) and will produce a story by transforming those material, creating a text. As in any production, a surplus remains that in Marxism is Signification: the text says more than the author meant to say because the text uses all these other voices, raw materials in its creation. Also, the text carries a tension between the author’s intention/meaning and the linguistic capacity of these other voices of the text.

A bourgeois critic thinks the author is to be found in the raw materials (the cotton) of the text, but a Marxist critic would say that the tension needs examination. The text becomes fissured, decentered. The text’s historical time dictates what the text can say so that there are certain things the text cannot say or even think. For a Marxist literary critic, the questions to explore are what is impossible for the text to say? What couldn’t the author say because of ideology? How does the text perform society?
