The true purpose of education is to make minds, not careers.

The violence of war is random. It does not make sense. And many of those who struggle with loss also struggle with the knowledge that the loss was futile and unnecessary.

Many of us, restless and unfulfilled, see no supreme worth in our lives. We want more out of life. And war, at least, gives a sense that we can rise above our smallness and divisiveness.

The New York Times is an institution that attracts careerists, who are drawn to power and access. This gave me a kind of a free hand. The kind of work that I wanted to do, most of the other reporters didn't want to do. I was not doing lunch. I was not sucking up to officials. I was writing from the street.

I think most generations tend to learn the lesson of war the hard way. There is a deep attraction to the empowerment. 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.

The failure to dissect the cause of war leaves us open for the next installment.

Turn off your televisions. Ignore the Newt-Mitt-Rick- Barack reality show. It is as relevant to your life as the gossip on “Jersey Shore.” The real debate, the debate raised by the Occupy movement about inequality, corporate malfeasance, the destruction of the ecosystem, and the security and surveillance state, is the only debate that matters.
