Shim of Theseus

From Wikipedia, the free encyclopedia

“The Ship of Theseus is a thought experiment about whether an object which has had all of its original components replaced remains the same object. According to legend, Theseus, the mythical Greek founder-king of Athens, rescued the children of Athens from King Minos after slaying the minotaur and then escaped onto a ship going to Delos. Each year, the Athenians commemorated this by taking the ship on a pilgrimage to Delos to honor Apollo. A question was raised by ancient philosophers: After several centuries of maintenance, if each individual part of the Ship of Theseus was replaced, one at a time, was it still the same ship?”

The Shim of Theseus is a thought experiment about whether a biological female (male) who has had all of their anatomical and cellular components replaced with biologically male (female) cellular components remains the same sex. (Note: This is not a question of gender identity but rather sexual plasticity in the biological sense).

Some questions arise:

  • At what point does the transition occur?
    • The original intent? Some functional capability (ex. reproductive ability)? Presence primary/secondary characteristics? Social acknowledgment?
    • Is there even a “transition” to speak of? Ie is sex continuous?
  • Is it biologically feasible?
  • Does developmental history matter?
  • Is it technologically feasible?
