At issue is not only knowledge of the world but our survival as individuals and as a species. All the basic technologies ever invented by humans to feed and protect themselves depend on a relentless commitment to hard-nosed empiricism: you cannot assume that your arrowheads will pierce the hide of a bison or that your raft will float just because the omens are propitious and you have been given supernatural reassurance that they will. You have to be sure.

war is, in some not yet entirely defined sense, a self-replicating pattern of behavior, possessed of a dynamism not unlike that of living things.

Well I do think there are people who are habitually negative and depressed and take the opposite approach because they imagine the worst, and their minds become dominated by that. They let their own emotions and expectations transform their perceptions of the world.

Cheerfulness, up to and including delusion and false hope, has a recognized place in medicine.

However and wherever war begins, it persists, it spreads, it propagates itself through time and across space with the terrifying tenacity of a beast attached to the neck of living prey. This is not an idly chosen figure of speech. War spreads and perpetuates itself through a dynamic that often seems independent of human will. It has, as we like to say of things we do not fully understand, 'a life of its own.

Human intellectual progress, such as it has been, results from our long struggle to see things 'as they are,' or in the most universally comprehensible way, and not as projections of our own emotions. Thunder is not a tantrum in the sky, disease is not a divine punishment, and not every death or accident results from witchcraft. What we call the Enlightenment and hold on to only tenuously, by our fingernails, is the slow-dawning understanding that the world is unfolding according to its own inner algorithms of cause and effect, probability and chance, without any regard for human feelings.

Yes, I think especially the Pentecostal churches, you know, that there's been such a growth in Pentecostalism. And it's a rejection of the much more dour and barren kind of Calvinist worship and also, the very formal Catholic forms of worship.
