Pfeffer, Rose.  "Eternal Recurrence in Nietzsche's Philosophy." Review of Metaphysics 19 (December 1965): 276-300.

Excerpt:

“The importance of the theory of eternal recurrence within the

framework of Nietzsche’s thought has been a subject of dispute
among Nietzsche scholars. Some dismiss the idea as a subjective,
religious experience and a deceptive illusion.1 Others acknowledge
its importance, but see it in irreconcilable opposition to other
central concepts of Nietzsche’s philosophy, primarily to that of the
will to power.2”
