  McTaggart entertained several theories about the nature of the C-series. One theory that he did not seriously argue against is the view that the C-relation is a primitive transitive, asymmetric relation for which nothing positive may be said concerning  it.[10] I will briefly discuss a theory that he entertains in his article “The Relation of Time to Eternity”, which was re-published in Mind in 1909 but was written at least two years before. (This article is also reprinted in Philosophical Studies.)
