Emotions are the prime reasons driving the human acts and also the human history. And since the human emotions are unpredictable and uncontrollable it is the major cause of the tragedy play called “The History”.
Lets take as an example the brake out of WWI. Nobody predicted it and there was no rational reason to start it. At 1914 everything seemed to be in positive trend and positive evolution. Science (Atomic and sub atomic discoveries, psychology, etc.), technology (benzine and diesel motors, electricity, aeronautics, etc), economic prosperity due to new technologies and products, social evolution (introduction of social legislation of pension systems, education and health care) and also international political stability due to family relations of all the European kings. And suddenly a confused student, who lost his way, kills a prince, and an 80 year war starts, that its tragic political consequences diminished only recently with the collapse of USSR.
Now lets take the world today and to where the emotions drive us;
On one hand the world economy is advancing to more riches and more evenly distributed wealth among different regions. The Asian and South American economies are caching up with the highly developed US-Europe-Japan. Technology is advancing at accelerating speed, introducing to the market every few years a consumption paradigm changing new product. Science is advancing in wide range of new fields. Birth rates are collapsing in increasing speed. These are all good news.
But what about the bad news?
a. The environmental problem. The world failed to create a global institution that can enforce environmental protective policy with all the price to be paid of such a policy. As an obvious example of price to be paid is the need to reduce hydrocarbon fuel usage, but also the need to change the custom of meat eating.
b. The wake up of irrational anachronistic ideologies mainly in the Muslim world, that see destruction as a legitimate tool to achieve their goal of imposing their faith on rest of the world. The worst of all this is that their system denies the reality, that political-legal-social-religious system, that was very successful 1400 years ago, cannot be applied on a world with population more than twenty fold higher, with hunger to consume more and more products. It may be said that when the realities exposes the difficulty to implement their fundamental policy (as it is happening in these days), the religious fundamentalist movement will be eventually marginalized. Yet, because of the level of commitment of the followers, by using the tools of the modern world (as they showed they know to do), even very small group of believers can endanger the whole human civilization.
