It’s a recognition that man, left to his own devices, will act in an evil manner, due to his fallen, sinful nature.

That’s the correct vision of the nature of man.

In contrast, the source of all ideological error is the assumption that man is “basically good”.

OK...

That’s the correct vision of the nature of man.

No question mankind is fallen.

In contrast, the source of all ideological error is the assumption that man is “basically good”.

That's the source of *all* ideological error? I could see it being the source of most anthropological error, but you really can't think of *any* ideological error that isn't directly descended from that one error?
