One of the hardest things we can do as readers is disagree with the methods of authors we agree with ideologically. It makes us feel good to find authors who agree with us, but this is when we should be at our most skeptical. Searching the world for self-justification is not a worthwhile goal, it simply turns you into another short-sighted, argumentative know-it-all.
That's from Keely's scathing, analytical
review of The Giver. I like the idea that we should be especially skeptical of the arguments of those we agree with, to counteract out
natural tendency to the contrary.
