Unique?

Is Poul Anderson unique in addressing both causality paradoxes; certainly in the comprehensiveness of his treatment of both? (Thinks: it is safer to frame this kind of proposition as a question than as a factual assertion.)

In the preceding post, with Anderson as our axis, so to say, we also referred to time travel works by:

SM Stirling (the series has to continue)

Audrey Niffenegger (we hope for a sequel)

HG Wells (whatever happened to the Time Traveller?)

Robert Heinlein

Tim Powers

- and we know that there are others. What an outstanding list of authors! This literary sequence will continue as long as there are authors and readers with intellects and imaginations.
