Ring them bells for the blind and the deaf

I have so many questions in my head. I just need to know why I can feel my own skin and not others. How did we ever develop these emotions and how did we learn how to name each feeling. Because I'm starting to feel so much for the world. :(

Ring them bells for the blind and the deaf,
Ring them bells for all of us who are left,
Ring them bells for the chosen few
Who will judge the many when the game is through.
Ring them bells, for the time that flies,
For the child that cries
When innocence dies.
