this song is awesome!

I would guess that the 4 horseman refers to the biblical notion that 4 horsemen: white, red, black, pale, which forebode the apocalypse, or in a personal sense, perhaps death.

I am not too sure about the lyrics, they seem to have a flavor of acting in a meaningful way before those horseman get you-don't sit around bitching about how unjust or bad life is if you don't try to do anything about it. Drugs and holding yourself up to your own (perhaps lofty) standards-put yourself on trial are featured as well.
