What exactly is tolerance, a positive word? No, neutral words are appropriate. What does it mean if it were put to the level of philosophy? As a popular historian, Fang Long seems to have more philosophical components, because he is a doctor of philosophy, but most of the books he writes are about history, and most of them are European history. A person who studies philosophy changes his career to writing history books, and you can imagine how readable his books are. Tolerance in such an academic background writer under the pen of the difficulty of understanding is naturally unimaginable to ordinary people, I originally borrowed such a book, casually turned over, think it is OK, did not expect to read, that kind of abstract degree is simply more than I expected, although philosophy books I do not like very much, but also occasionally look, like a set of books in the North Gate I still insist on patience to read, although there is no gain, but also learned some related terms and celebrity research areas, but "Tolerance" has both philosophical abstractions, There is also a specific historical background, read nearly half of it, and did not understand what was going on. An old man who has not been to the academy for a day and has been imparting knowledge all his life is Socrates. Sitting on the hill every morning to observe the rising sun, thinking about the laws of human society, although he was finally sentenced to death, he could leave the cell to survive, but Socrates resolutely executed himself, until he drank poison and died, he was still as calm as water, forgiven everyone, which is the best embodiment of the practice of tolerance understanding; the second example listed in the book is the Trojan War, which launched a decade-long war for a woman named Helen, and finally although the Greeks defeated the Baraks, But it also paid a heavy price, even the heavenly gods did not want to see such a tragic ending, who tolerated whom, can not see, a little incredible! Thousands of years of European history, crusades, the capture of Byzantium, the spread of Christianity, Jesus, Solomon, Mudnahan, etc., a series of events in history have been written in only a few thousand words, intriguing to read, is it a narrative of history, or depicts the development and changes of society, but it has nothing to do with tolerance, does Mr. Fang Long want to use European history to explain that the history of human society is actually a history of tolerance!
