Readers of National Review Online have a chance to peruse the first in a series of columns from Dennis Prager defining differences between liberals and conservatives.

Difference No. 1: Is Man Basically Good?

Left-of-center doctrines hold that people are basically good. On the other side, conservative doctrines hold that man is born morally flawed — not necessarily born evil, but surely not born good. Yes, we are born innocent — babies don’t commit crimes, after all — but we are not born good. Whether it is the Christian belief in original sin or the Jewish belief that we are all born with a yetzer tov (good inclination) and a yetzer ra (bad inclination) that are in constant conflict, the root value systems of the West never held that we are naturally good.

To those who argue that we all have goodness within us, two responses: First, no religion or ideology denies that we have goodness within us; the problem is with denying that we have badness within us. Second, it is often very challenging to express that goodness. Human goodness is like gold. It needs to be mined — and like gold mining, mining for our goodness can be very difficult.

This is so important to understanding the Left–Right divide because so many fundamental Left–Right differences emanate from this divide.

Perhaps the most obvious one is that conservatives blame those who engage in violent criminal activity for their behavior more than liberals do. Liberals argue that poverty, despair, and hopelessness cause poor people, especially poor blacks — in which case racism is added to the list — to riot and commit violent crimes.
