The Medieval period is a dark shadow in the European history. In general, the term "Medieval" refers to the period from the 5th to the 15th century AD; that is from the collapse of the Western Roman Empire to the era of the Renaissance and the Age of Discovery. The Medieval period was also known as the Dark Ages, a period haunted by famine, plague and war, and many major events took place.

First, there was the collapse and collapse of the Roman Empire that changed the structure of the whole world. The disappearance of this powerful, dominant empire had enormous impact to the world. Another major incident was that the population of Europe had begun to decline, and the Black Death that broke out between 1347 and 1350 took the lives of one-third of Europeans. Third, there were religious conflicts, and the clash between different countries and the resistance of the peasants had reached the peak in the history.

In 1484, the clergyman Heinrich Kramer and Jacob Sprenger's notorious witch-hunt hand book Malleus Maleficarum listed a variety of ways to identify witches, and launched massive witch trials in Europe. The medieval witch trials had a very dark side, and the "witches" who were executed were all innocent women.

In fact, throughout Europe at the time, about 100,000 to 200,000 people were executed in the course three centuries under the name of witch-hunt, most of them women, including Joan of Arc, and burning on the stake was the most common mean of execution; there were also various horrific instruments of torture, which are still visible in museums today. The world's irrationality had reached its peak, and the medieval period has become veritable Dark Age.

In Dark Age like this, logic and reason were subdued by the irrational society, and more often there were only meek, secondary rationality and logic.

Compared with the real world, the irrational society has gradually reached its peak with the internet; the most obvious is Donld Trump being elected and the Brexit. Trump's victory is what we call the result of the "alt-right movement", that is all rationality and logic are not important. What is important is opposition that opposes to everything, and venting out dissatisfaction; Brexit in a perfect example of the outcome of such irrational characteristics in the society.

All calculations and data indicate that the social trauma caused by Brexit may be greater, but the British society still voted to leave the European Union. No one cares about the statistics; people acted according to their own whims, even impulsively, from the queen to the nobility from the middle class to the ordinary labors. Irrationality completely defeated reason and logic. What has happened to this society?

Unlike those bankers who are rational and logical, the views of the general public and the middle class and their public opinion on the internet are actually the result of a sharp decline in the marginal benefits and opportunities of the world. The West has been in a peaceful development environment for a long time after World War II; the whole society is in an ultra-stable state, its structure and order are super stable, yet the negative entropy continues to accumulate and globalization has further aggravated this process. In the past, one could still look forward to the future and seek opportunities for personal development, yet now the opportunities in the future have become very slim and impossible. Therefore, the only thing the public and the middle class can do is to smash the dreams of others and deprive others of their opportunities. This is an inevitable choice; this is a realistic option for them to remind the society to pay attention to their own interests as a social class. This is the origin and key of the rational outbreak.

At 6 o'clock in the morning, you stand at the street of the London Underground Station. From 6 o'clock to 7 o'clock, you will see a lot of young white people rushing out of the subway station, they are the first people to go to work, and few of them are colored people. From 7 o'clock to 8 o'clock, you will see a group of older whites, mostly middle-aged, whose suits symbolize their success. Between 8 and 9, a large number of people rushed out of the subway station, including more and more people of color. For the first group of people, they work hard, but do they have more opportunities in the society? The answer is certainly no, so their anger, disappointment, dissatisfaction, jealousy and struggle are imaginable. They are the foundation of an irrational society.

Final Analysis Conclusion:

The world that has lost its hope is a terrible place. The dark, irrational future world cannot be reasoned; this happens to the United States and the United Kingdom, and more countries and societies will follow. What we see cannot be explained by reason and logic; both statistics and classical theories have to be cast aside. People use emotions and desires to express everything, hence this explains well the occurrence of revolutions, strives, conflicts, helplessness, and even arrogance. People are only using destruction to seek attention, to lay the groundwork for future revival, and there is no boundary and bottom line for this. Such a century can only be a dark age, and this is the reality.
