Where does evil come from? And how did it become so powerful? We can have a sense that when we try to do right by one another, we aren't merely striving against ourselves. The feeling is that we are struggling against something-someone-else. As if there's a force-a person-that wishes us ill. In his letter to the Romans, the apostle Paul describes just such a person: Sin, a cosmic tyrant who constrains our moral freedom, confuses our moral judgment, and condemns us to slavery and to death. Commentators have long argued about whether Paul literally means to say Sin is a person or is simply indulging in literary personification, but regardless of Paul's intentions, for modern readers it would seem clear enough: there is no such thing as a cosmic tyrant. Surely it is more reasonable to suppose "Sin" is merely a colorful way of describing individual misdeeds or, at most, a way of evoking the intractability of our social ills. In The Emergence of Sin, Matthew Croasmun suggests we take another look. The vision of Sin he offers is at once scientific and theological, social and individual, corporeal and mythological.
He argues both that the cosmic power Sin is nothing more than an emergent feature of a vast human network of transgression and that this power is nevertheless real, personal, and one whom we had better be ready to resist. Ultimately, what is on offer here is an account of the world re-mythologized at the hands of chemists, evolutionary biologists, sociologists, and entomologists. In this world, Paul's text is not a relic of a forgotten mythical past, but a field manual for modern living.
