We its obvious that he is criticising the idea that our own human nature is a sin. Like a few others on the album it seems to have some anti religous feelings (The Line: "If we're going to break it down with any logic, it's absurd" reminds me of the line from we will fall together "all we have is logic and love on our side" i think they are similar). Forty days might also be a referance to the flood or less likely jesus' forty days alone.
