Hologram[]
Aholographic simulation of Socrates was among thehistorical figure profiles studied byThe Doctor, in2373, during his attempt to expand hispersonality subroutines. In the simulation Socrates playedkal-toh againstT'Pau, as The Doctor conducted his interviews with the other historical figures.
When The Doctor's alter-ego, created from the combined 'dark threads' of the sub-routines of these historical figures, began to destabilize his program, he took to altering their sub-routines, to solve his own issues. His "work" was later discovered byKes, when she found the upper body of the Socrates hologram laying on theholodeck floor. (VOY: "Darkling")
