The word "Person" comes from the latin word "Persona" or "Prosopon" (Greek), which originally referred to the masks worn by actors on stage.
So in a way, when you think to yourself, " I, I am a person" what you're really thinking is "I am the act which i have come to believe in".
We trick ourselves into believing we are singular, that we are one person.
You can look at your legs and your arms and see they are two different things but they are part of the same organism.
Then it gets trickier when you look at bees and flowers, you believe they are different, but they are codependent and therefore, they are in fact one organism.
