In my second year of Harvard Divinity School, where I was studying to be a minister like my father, I met a guy named Robert Cox, who had been the editor of the Buenos Aires Herald during the Dirty War in Argentina. Bob used to print the names of those who had been disappeared the day before, above the fold in his newspaper. It was a kind of an awakening to me to see what great journalism can and should do.

Becoming vegan is the most important and direct change we can immediately make to save the planet and its species.

The rush of battle is often a potent and lethal addiction, for war is a drug.

One needs solitude and quiet to think. The cacophony of modern culture is designed to make that impossible.

Freud is right: societies either become locked in a collective embrace of Eros, as individuals do, or a collective embrace of Thanatos, the death instinct. They swing between the two. The notion that societies are naturally prone toward self-preservation is wrong. Self-annihilation can be deeply addictive, intoxicating, enticing. So I take a darker view of human nature, that war is probably always going to be with us. I think history bears me out.

Again, although I'm not a particularly religious person, I go back to the religious left that I come out of: There are moral imperatives to fight back. As Daniel Berrigan says, "We're called to do the good." And then we have to let it go. It's not our job to know where the good goes.

We have been very effectively pacified by the pernicious ideology of a consumer society that is centered on the cult of the self - an undiluted hedonism and narcissism. That has become a very effective way to divert our attention while the country is reconfigured into a kind of neofeudalism, with a rapacious oligarchic elite and an anemic government that no longer is able to intercede on behalf of citizens but cravenly serves the interests of the oligarchy itself.
