Enlightenment thinkers thought that almost all of the world's problems were in direct result of the lack of reason. With the development of reason they thought many problems were solved. But that was only a theory, an idea that has not helped anything. It is constant, everyone in the world wants to make a model society, and make things better, a natural inclination, which has nothing to do with reason. The question of deciding whether or not "reason" is helping people and nations today is a hard one. Which country does on need to look at to decide?
Looking at America, some could decide that, yes, reason is helping, where others could say no. If we were to look at, say , the Congo in Africa, and all the massacres, then some would say where was reason then? Now what is "reason"? Reason is the be00nlief and idea that more educates people will make better decisions. Now has "reason" helped the United States? Yes for the most part, intelligent people have created a free-based country, made a constitution meant for change, and overall that believes in the good of the world.
Now the United States is not all good, our country is based off of slavery for a long time and women couldn't vote for a long time, only about 40 years ago did they get the vote. At the same time though, look at Enron. All the executives of the company were college educated, considered intelligent, but they basically robbed hundreds of people of their money by not informing them that the company was about to crash and to sell out. Look at Gary Winnick, who was a competent man who helps create a hoax of a company that folded in over night.
So for the most part one can conclude that "reason" does not help at all, its just another idea like God, which cant be proven or disputed, I mean what's the point of arguing over something unable to be proven? Is change part of the "reason" theory? No because the "reason" theory? NO because with time comes more issues. All of which have to be dealt with in time. For a second country, look at Russia. With a huge population of 148 million, and the average income of two thousand dollars a year, some would say that its not a successful country.
Russia, in its day was one of the worlds super powers, and actually for a time was basically the top country in the 1900's. Today the new president there is Vladimir Vladimirovich Putin. HE is a ex-KGB member and the chosen successor of Boris Yeltsin, the previous and deemed corrupt president. The USA has given Russia "bail-out" packages, which were in effect huge sums of money, but some political experts say that the Russian people will never see it because before it gets to them it is already out the door and into some banks over seas by the supposedly "reasonable" and "competent" leaders who want to restore mother Russia.
Now as one were to understand on the basis of the definement of "reason", the upper class in effect should be educated, hence they should be better with the money given to them to help build their nation again. It seems that reason is used improperly. All philosophers look for the best way to live ones life in the best ways possible. "Reason" was just another idea to help the expansion of people's minds. IT was used to open people's minds to an idea that there are better ways to do things and being educated was absolutely a plus.
The idea is a good one in that it is true that a reasonable person, if in a tight situation, will tend to think for the best of their friends and family around them, but at the same time as other things, its not always true. So for the most part, "reason" is another idea, such as the "cookie cutter" idea, where for every thing we see there is a perfect version somewhere else and that "else" is heaven so to speak, which some say yes and others say no. So really its but to what one is willing to apply to the world and believe.
