The basic goodness of humanity.

I've come to the conclusion that the divide between conservative and liberal political thought, particularly among Christians, can be traced to what each believes about the fundamental nature of people.

I think that politically-liberal Christians believe that, as beings created in God's image, we have a divine spark that makes humans naturally good. It is the external environmental influences that pressure naturally good people into making bad choices, leading to bad lifestyles. Therefore, if you can eliminate poverty, illiteracy, and social inequality, humanity's condition will be improved and everyone will live in peace. This is why they embrace social programs and push for social justice.

On the other hand, politically-conservative Christians believe that, though created in God's image, humanity has been corrupted, and therefore our natural impulses are not for good, but for evil. Environmental factors may play a small part in decision-making, but goodness can only be achieved through an internal transformation by God. Social programs don't improve humanity's condition, but rather allow another avenue for abuse by naturally selfish people.

I lean toward the latter view, but I definitely have sympathy for the former. Sometimes it seems easier to change a person's environment than to change a selfish, stony heart.
