An archetypal literary critic would argue that allusions are made to literary works because

the archetypes found in these literary works determine the meaning and function of the literary piece. Moreso, the subconscious affects human behavior.

Explanation:

Archetypes which are incorporated in literary works come in the form of images, symbols, motifs, etc. which all have underlying meanings.  The archetypal critics believe and argue that it is these archetypes that form the basis of literature as readers are able to connect to these images.

They believe that through dreams, humans are somehow able to connect to the underworld and that literature is an imitation of the dreams which humans can easily relate to.
