In War, Peace and Human Nature, Douglas Fry et al argue that (1) the belief that war is part of human nature is itself destructive and (2) war is not part of human nature.
A view, erroneous though it may be that war is ancient and presumably thus reflects some natural feature of humankind or human social life, feeds a suspicious and hostile view toward other peoples and countries, making the preparation for war and the practice of war that much easier. The reasoning, or in many cases “gut reaction,” seems to be: if war is in human nature, then we’d better be prepared to fight and perhaps strike first. This implicit assumption, in great part simultaneously stemming from and reinforcing of the violent view of human nature, can be seen as contributing to arms races, preemptive strikes, excessive spending on weapons, hostility toward others, and inordinate fear of other nations or groups, who are by this thinking, naturally inclined to attack. I am suggesting, in other words, that in widespread assertions that war is ancient, we are seeing a cultural belief with very important real world ramifications. Such a view may be in the short-term self-interests of a minority (e.g., arms dealers), but it is not in the long-term interests of humanity overall.It's an important point. And much of the rest of the book backs up the assertion, that over the whole period of human existence, war is not an intractable feature of humanity, Mr Fry has this to say, summing up the evidence gathered and written up by other contributors to the book:
[Steven] Pinker's thesis that chronic war stretches back over the far-reaching millennia before the agricultural revolution is not substantiated by the actual data. ... The worldwide archaeological evidence shows that war was simply absent over the vast majority of human existence .... —the time period beginning far to the left side of [an n-shaped] curve. But with a gradual worldwide population increase ..., the shift from universal nomadic foraging to settled communities, the development of agriculture, a transition from egalitarianism to hierarchical societies—and, very significantly, the rise of state-level civilization five thousand to six thousand years ago—the archaeological record is clear and unambiguous: war developed, despots arose, violence proliferated, slavery flourished, and the social position of women deteriorated. This comparatively recent explosion in pre-state and then state-based violence is represented on the rising left side of the letter n in the curve, but taking place within the last 10,000 years. (My emphasis.)Conclusions? People who believe world peace is possible are not being irrational or going against human nature. Violent political conflict is not inevitable.
Where does the Social Policy Bond idea fit in? Simply: knowing that world peace is possible, we can issue World Peace Bonds as a way of rewarding the people who help achieve it. There are reasons why such bonds have not been issued (they're untried, they threaten existing institutions ...etc) but a big one is that people think that world peace is some Edenic, idealistic vision, not for this world. What Mr Fry and the other contributors to his book show is that world peace is not only possible, but it was, for the greater part of man's existence, a reality.
