Is it enough to condemn evil without trying to understand it?

I’m not sure the answer is obvious. On the one hand, dwelling on the wretchedness of villainy (to paraphrase Obi-Wan Kenobi) can be corrosive to one’s inner life. It’s why we humans often tell one another to “focus on the positive,” or why St. Paul instructs his Philippian friends similarly:

Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.

On the other hand, two things can go wrong if we condemn evil without understanding it. First, we could miss out on the fact that the “evil” isn’t evil at all, but simply another perspective that merits a hearing in dialogue or some other format. Second, in cases when the evil is evil, we could miss out on uncovering the best ways to defeat it.

Throughout his must-read article in this month’s Atlantic, contributing editor Graeme Wood puts the Islamic State phenomenon squarely in the second category. To correct this error, he puts forth a well-researched report on the specific beliefs that drive the caliphate.

If Wood’s analysis is correct, then actual dialogue with the jihadist leaders, even if remotely desirable, is impossible: their interpretation of Islam requires them to forswear the peace and bridge building that dialogue fosters. However, understanding the intellectual foundation of ISIS would greatly enrich our dialogue about ISIS—particularly the dialogue of Western leaders as they seek more intelligent, more effective strategies for bringing the rogue state down.

That is Wood’s thesis, and I agree. It doesn’t make reading about the Islamic State any less stressful or horrifying. A steady diet of such articles would mess with my mind, and probably yours too. Which leads us back to the question: does it make any sense for average citizens, with no power over strategy, to let this stuff into their minds? What do you think?
