And yet I uncovered a wealth of conversation about the meaning of those four lines.
The most compelling analysis I read was that this is a song about God, told in a call-and-response style with God speaking the second and fourth lines.
God is absent and uncaring in the face of Man’s devotion. Reminds me of Randy Newman’s ‘God’s Song (That’s Why I Love Mankind).’
Another reading is similar but puts the second and fourth lines in the mouth of another person — the subject of the first person’s unrequited love.
Or could all four lines be delivered by the same person, perhaps saying he doesn’t care about some transgression or fault of the person to whom he’s singing?
Know I don’t care
Know that I see you
Know I’m not there
