Ironically, though our society of affluence brings safety and stability, it doesn't bring psychological health. As wealth goes up, suicide and depression rates tend to go up. I read one study that compared women in North America with women in Nigeria, and the group with the highest rates of depression was urban North American women, which is the wealthiest. Now, there are obviously huge stresses that come with poverty, but the poorer the society, the more collaborative people have to be.

I would never want to pass a law limiting freedom of speech, but that doesn't mean we have to condone statements that undermine basic national unity and respect. Imagine being asked to defend a country where some citizens say the man in the White House isn't their president. Or a major presidential contender accuses the commander in chief of not even being a U.S. citizen. Those kinds of statements erode trust in our democracy, and it's up to both parties to publicly reject them. We have to restore confidence that we are a nation that loves and believes in itself.

Here's an easy way to see if a war movie is being truthful: If you see an explosion on a faraway hillside and the sound of the explosion and the detonation of the bomb happen at the same time - if they're putting the sound and the vision together in the same moment - they're going toward our cultural understanding of war, not the reality of war.

I don't think journalists in World War II were objective about the Nazis, and I don't think they should have been.

Of the primary emotions, fear is the one that bears most directly on survival. Children show fear. Adults try not to, maybe because it's shameful, or, in some circumstances, dangerous. The fear response is automatic, though, and your body runs through its reflexes whether you want it to or not.

If you get an infection, you get a fever; the fever is your body dealing with the infection. If you get traumatized, your mind and your brain have a reaction to that trauma. If you're not dreaming about it, something's probably wrong.
