I've been accused, in some comments on a posting, of believing that "a simple trust in reason will trump instinct and the problem of short term thinking." Well, Guy, let me stop you there. The truth is not so simple.
Thought emerges from deeper levels that are largely unknown. There is the legacy of evolution that writes the definition of the human species in our genome; there are the biases and passions that wash our mind in sudden waves and slow tides of hormones; there are layers of belief deposited by our experiences, our culture, our society, our family. If you believe that quantum-level events are involved in thought, then add that to the complexity. But do not fall for the reductionism that says that thought is nothing but genetics, experiences, and quantum events. Instead, thought emerges from them, here and there - now and then - to this one and that one. (So I've heard). And reason emerges from thought with a similar frustrating lack of consistency.
In other words, thought is an emergent property of mind, and reason an emergent property of thought.
People are sometimes reasonable. They can even display forethought. In a war or other emergency, for example, the Swiss can depend on having well-stocked shelters, and even underground hospitals, sufficient for 114% of their population. Similarly, as I have pointed out, Canada maintains enough antiviral doses to administer to the entire population in case of a flu pandemic. Making adequate preparations for an emergency seems like good reasoning to me.
Of course, people sometimes fail to show such reasoning ability. For example, the corrupt culture of banking is likely to curb the bankers' freedom of action in numerous ways. The golden goose has been plucked, is naked and shivering in the public gaze, and may yet find itself partially cooked. Still, the lack of reason in one group of people does not negate its presence in another.
The specific case I made in the article you responded to was that politicians should make the military place a higher priority on their preparations for natural disasters. Merely a "higher priority": There are no opposites of "reason" and "unreason" to talk about here, but just a matter of how much gets allocated here, how much there.
We have problems in our culture, our economy, and our governance. It was ever so. In 1960, in Virginia, I would have gone to jail for having married a non-white, and faced other charges if they could prove that we made love. In the 50's and 60's the FBI operated like the STASI, keeping files on the great and the good among the public, and the CIA ran illegal experiments in mind control. In the 30's, the economic problems were worse than now and the United States faced a fascist coup. I know enough of the past to not believe that our problems are worse. I've seen the apartheid regime dismantled in South Africa by a truly great man, I've seen another preside over the dismantling of the Soviet Union, which had seemed eternal. I won't make the mistake of thinking that our present problems are invulnerable to change.
