Human

Humans are human, just like humans are human, which is kind of like how humans are human.

Humans are human.
  No matter how much time divides us,
  no matter how much technology guides us,
humans are what they are,
  human.

You have heard these things then,
  you hear these things now,
  you will hear these things later.
Learn to listen, not just hear:
  that is the key to freedom.

They say ignorance is bliss,
  but when knowledge keeps us free,
    to be ignorant
      is be enslaved.
