The Ship of Theseus asks whether something remains the same object if all its parts are gradually replaced.
At the end, it is the same ship. At the end, it’s not the same ship.
When you learn new things and eliminate bad habits, sooner or later you will be a new man from the perspective of others, which is not the same you. (not the same ship) But for you, you are the same man who evolved. (same ship)
To others,
who only see the changes from the outside, your new behaviors, new beliefs, and new traits can make you appear like an entirely different person,
almost as if the original “you” has been replaced piece by piece.
But from within,
your sense of self is tied to an unbroken stream of consciousness: every change you make still branches from the person you were yesterday, last year, or ten years ago.
Thus the Ship of Theseus becomes a mirror for personal growth.
Who you are is both what you preserve and what you change.
IF YOU DON'T REPLACE THE OLD PARTS, THE SHIP SLOWLY ROTS, WEAKENS, AND BECOMES HOPELESSLY OUT OF DATE.
Are you replacing parts of yourself with something better each day, or sailing on as the same old ship?
