1. Before reunification, Germany was always in turmoil, with more than 3 vassal states fighting back and forth, and people were most likely to think in wartime. What a profound ideological precipitation it is to continue thinking for more than a thousand years; 2, good at thinking and rigorous; 3. In German thinking, there are more cultural colors than British and American empiricism, which can be seen in German music, philosophy and literature. German artists disdain to create visible and figurative works such as painting, but prefer to create flowing and abstract works such as music. Germany is obsessed with culture, while English law creates civilization. 4. The language of ancient philosophy was mainly Latin and ancient Greek. In the 18th century, in order to spread philosophy, popular language was gradually adopted, and German was the most rigorous and developed well.

second, this is inseparable from the rigor, learning and respect for authority of the Germans.

to be a thinker, you must learn, and you must learn in a down-to-earth manner. Learning depends not only on personal wisdom, but also on a "giant's shoulder"-a mature education system, a social atmosphere of learning, respect and trust for academic authority, and an academic atmosphere of "a hundred schools of thought contend and a hundred flowers blossom". The success of any great man has historical inevitability, and it is absolutely not accidental that Germany can produce many great thinkers. What China lacks now is the soil that nourishes the flowers in full bloom. Since the respect for Confucianism in the Han Dynasty, China's scholarship has been under the shadow of hegemony, and it is of course difficult to breed great thinkers.

third, geographical factors. Germany is located in Central Europe, and the cold weather has effectively reduced outdoor activities, leading Germans to like to stay at home. Germans are silent and serious by nature, so they pass the time at home by reading and thinking. These beneficial mental activities have promoted the development of Germans' critical thinking ability, and the cold weather has contributed to the active thinking, which laid the foundation for philosophy.

economic factors. The main body of Germany is Prussia, and Prussia's economy is very developed in Central Europe (Prussia was the last one to unify Germany). Philosophy is a kind of leisure enjoyment, and only those who have leisure time have the energy to think about philosophy. Most German philosophers are well-off and well-fed, so they can have a lot of time to think about problems instead of learning a technology for survival (the apprenticeship system in Germany is perfect and lifelong). This is also a foundation.

of course, the above factors are only superficial, not physical. On his deathbed, Mr. Qian Xuesen once asked, "Why can't China produce a master?" Because the master will not appear alone, the emergence of the master has a background. German philosopher Karl Karl Jaspers (also a German) said that an axis period of world history, in a certain period, human civilization concentrated in the Big Bang, giving off dazzling light. In fact, this can be summarized as "the country is unfortunate and the poet is lucky". When philosophy is developing vigorously, it is mostly an era of great social change, which is the fundamental reason.

Germany has been divided, and it was not until 1871 that the country was unified. During the separatist period, there are always forces that want to achieve great achievements and unify the country, which inevitably requires recruiting talents (so-called corporal Li Xian), so the political environment is relatively relaxed and the inclusiveness and diversity of society will be enhanced. This provides fertile soil and nutrition for the development of philosophy. China's contention in the Spring and Autumn Period and the Warring States Period, metaphysics in Wei and Jin Dynasties, etc. are excellent examples.

economics stresses supply and demand, so does philosophy. Only when society needs it will there be supply. The division of German society has caused a lot of shame to the country, so they need some theories to point out the way for themselves and see the hope of the country (which is why Nazi philosophy ran rampant in Germany after World War I). Therefore, in order to answer people's doubts and to unify and transform the country, philosophical theories are constantly emerging.

nothing can be decided by a single factor. When all these factors (the factors I mentioned may not be complete) come together, things will happen inevitably. This may be the answer.

Fourth, generally speaking, it is because the Germanic people are not unified enough, so even though there are many smaller autocratic areas, they have been to the "iron-blooded prime minister" (German: Eiserner Kanzler；; "Iron" refers to weapons, "blood" refers to war), "German architect" and "German navigator" Bismarck (Germany's most outstanding politician in the 19th century) unified Germany, which was always divided. This situation has created Germans to worry about their country and people, and at the same time, they can imagine freely under the relaxed national conditions. You know, even if a relatively small region is autocratic, it is not strong enough to bind the people.
