Would you capitalize the name of literary theory in a criticism such add Marxism or feminism?

Yes, you should capitalize the names of literary theories like Marxism and feminism when they are used as proper nouns to refer to the specific theories.

Here's why:

* Specificity: Capitalization helps distinguish the theory as a named concept rather than just a general idea.

* Clarity: It makes it clear you're referring to the specific theoretical framework, not just a general concept related to the topic.

* Convention: This is the standard practice in academic writing and literary criticism.

Example:

* Incorrect: "The book was analyzed using marxism."

* Correct: "The book was analyzed using Marxism."

However:

You would not capitalize these terms if you are using them as adjectives or general concepts.

* Correct: "The novel presents a Marxist perspective on class struggles." (Here, "Marxist" is used as an adjective describing the perspective.)

* Correct: "Feminist ideas have influenced literary analysis for decades." (Here, "feminist" is used as a general concept.)
