Lyric discussion by Infinitly Surreal 

dylan is lamenting having been too idealistic for compromise, finding himself the mirror image of those he defined as 'the enemy' and realizing the world is more grey than black/white. he's describing being more aware of the world the way it is rather than how he felt it could be. it's a bit of a reconciliation between an older man (who feels younger, having been freed from his idealism and hard-charging, never-ending, and exhausting soldier for righteousness character) and settled to being more realistic about his surroundings and where he and society are going. or something.
