The Personal Identity Game

Who are you? What makes you the same person today as you were when you were born a few years ago? When did you begin to exist? And what will become of you when you die? 

Discover the answers that philosophers have given to these questions by playing with some cool thought experiments!


This game introduces three important philosophical theories of personal identity: 


Choose the theory you find most plausible based on the brief descriptions below, and press one of the green buttons to start the game. 


You are your body

You are a living organism characterized by functions such as respiration and metabolism. The end of these activities results in the end of you: you can lose an organ or a limb and still be you, but if you stop breathing and digesting you are no longer the same living organism. 

You are your brain

You are the tangle of neurons nestled in the grey matter found in your skull. In other words, you are your brain! After all, you can lose a limb or another organ and still be you, but you cannot be the same person if your brain gets irremediably damaged or altogether destroyed.

You are your mind

You are your memories and your character; more generally, your psychology. After all, if you completely lose your memories or your character traits change radically, people will say that it is no longer you, or that you have become a different person. 

This game has been adapted for The Philosophy Garden by Lisa Bortolotti and Nikk Effingham from a game originally designed by Anna Ichino, Andrea Guardo, Giuliano Torrengo, Samuele Iaquinto for the Philosophy Museum in Milan.
