"Enter a Soldier. Later: Enter Another" is a 1989 science fiction story by Robert Silverberg. It was first published in Asimov's Science Fiction.

When AI researchers attempt to replicate the minds of historical figures, their first success is Francisco Pizarro... who they then introduce to their second success, Socrates.
