Suppose there were an experience machine that would give you any experience you desired. It could stimulate your brain so that you would think and feel you were writing a great novel, or making a friend, or reading an interesting book. All the time you would be floating in a tank, with electrodes attached to your brain. Should you plug into this machine for life, preprogramming your life experiences? While in the tank you won’t know that you’re there; you’ll think that it’s all actually happening. Would you plug in?

Ship Of Theseus
The ship wherein Theseus and the youth of Athens returned from Crete had thirty oars, and was preserved by the Athenians down even to the time of Demetrius Phalereus, for they took away the old planks as they decayed, putting in new and stronger timber in their place, in so much that this ship became a standing example among the philosophers, for the logical question of things that grow; one side holding that the ship remained the same, and the other contending that it was not the same.” —Plutarch
Is the ship still the “same” ship, even though it has been entirely replaced, piece by piece?
