Let us run through this argument formally, and a little more slowly, for the sake of perspicuity. There is, of course, an obvious way for Schlesinger to avoid this contradiction. Thus, to avoid the contradiction, Schlesinger need only relativize statements about the actuality of worlds to the moments at which they are actual. The problem this poses for Schlesinger's attempted transientist solution to McTaggart's paradox is as follows. Schlesinger wants to avoid the contradiction which McTaggart derives by relativizing statements about the present to worlds in which they are true.
E is present' is true in W n .
E is present' is true when W n is actual. E is present' is true at m n . The rationale is that the moment m n extends through each of the worlds in Schlesinger's model. E is present' is true when W n is actual and W n is actual when m n is present. E is past when m n is past and E is present when m n is present and E is future when m n is future.
