The ship of Theseus, also known as Theseus's paradox, or various variants, notably grandfather's axe and (in the UK) Trigger's Broom (based upon the BBC sitcom Only Fools and Horses) is a paradox that raises the question of whether an object which has had all its component parts replaced remains fundamentally the same object.
The paradox is most notably recorded by Plutarch in Life of Theseus from the late 1st century. Plutarch asked whether a ship which was restored by replacing all its wooden parts remained the same ship. The paradox had been discussed by more ancient philosophers such as Heraclitus, Socrates, and Plato prior to Plutarch's writings; and more recently by Thomas Hobbes and John Locke. This problem is "a model for the philosophers"; some say "it remained the same, some saying it did not remain the same".

Famous quotes containing the word ship:
“I do not know if you remember the tale of the girl who saves the ship under mutiny by sitting on the powder barrel with her lighted torch ... and all the time knowing that it is empty? This has seemed to me a charming image of the women of my time. There they were, keeping the world in order ... by sitting on the mystery of life, and knowing themselves that there was no mystery.”
—Isak Dinesen [Karen Blixen] (1885–1962)
