What good am I?

I came across a reference to these lyrics in Bob Dylan's biographical Chronicles which I am reading at present. They are from his 1989 Oh Mercy Album and address some of the issues I was grappling with in my earlier "My Tribe" post. The inspiration for this song was him seeing a homeless man being harassed by policemen.

What good am I if I'm like all the rest,
If I just turned away, when I see how you're dressed,
If I shut myself off so I can't hear you cry,
What good am I?

What good am I if I know and don't do,
If I see and don't say, if I look right through you,
If I turn a deaf ear to the thunderin' sky,
What good am I?

What good am I while you softly weep
And I hear in my head what you say in your sleep,
And I freeze in the moment like the rest who don't try,
What good am I?

What good am I then to others and me
If I've had every chance and yet still fail to see
Bridge: If my hands tied must I not wonder within
Who tied them and why and where must I have been

What good am I if I say foolish things
And I laugh in the face of what sorrow brings
And I just turn my back while you silently die,
What good am I?
