Imagine understanding United States history with this view of human nature front and center (from the Synod of Dort which concluded — go figure — in 1619):

Human beings were originally created in the image of God and were furnished in mind with a true and sound knowledge of the Creator and things spiritual, in will and heart with righteousness, and in all emotions with purity; indeed, the whole human being was holy. However, rebelling against God at the devil’s instigation and by their own free will, they deprived themselves of these outstanding gifts. Rather, in their place they brought upon themselves blindness, terrible darkness, futility, and distortion of judgment in their minds; perversity, defiance, and hardness in their hearts and wills; and finally impurity in all their ­emotions. (III/IV.1)
