Check out this recreation of Thomistic philosophy at Original Sin: A Disputation. The article contains this passage, which was written to support the view that Original Sin was not a coherent theological viewpoint:

It is generally believed that theological schools such as Jansenism and denominations such as Calvinism bring in their wake legions of members with withered emotional lives, censorious views of their less austere neighbors, and a bleak, nearly blasphemous, view of God’s love. At least that is the picture handed down to us from countless sources in the culture, from Nathaniel Hawthorne’s novel The Scarlet Letter to more vulgar displays of the journalistic mind, such as H. L. Mencken’s scorn for the Tennessee literalists of his day or, more recently, the soap-opera treatment to which the Reverend Jimmy Swaggart was subjected a few years back.

And there must be something to this perception, at least if we are to take the testimony of certain people raised in the Calvinist tradition seriously. For example, Woodrow Wilson, a Presbyterian, suffered from a bleak and relentless depression stemming, according to his biographers, from the combination of his herculean efforts to spread democracy coupled with his firm belief that the vast majority of the human race was going to hell in any event. And Henry James, Sr., the father of the famous novelist Henry and his equally renowned philosopher brother William, suffered under a similar theology-induced depression until he had what he described as a "vastation" (clean sweep) and became a Swedenborgian.

To the extent this cultural perception is accurate, it must rest on what is the most illogical and contradictory aspect of the doctrine of original sin, at least as it is normally heard in the pew: that we are morally culpable for possessing instincts which we cannot help possessing. One is reminded in this context of Calvin’s weird, though logical, inference in his Institutes (II, i, 8) that "infants bring their own damnation with them from their mothers’ wombs; the moment they are born their natures are odious and abominable to God." To build a pedagogy on this premise is, needless to say, to invite disaster, as we learn in the poem "Holy Willie’s Prayer" by the Scotsman Robert Burns; one of the grimmest poems in the language, it depicts the vision of babies dropping right from their mothers’ wombs into hellfire.

Wow. Is that a fair depiction of Calvinism. I don't think it's written from an intentionally hostile position. But if it's historically inaccurate - like conventional depictions of the Reformation - let me know.
