Others live to eat, and I eat to survive-Thales is the founder of the earliest school of philosophy in Greece (Ionian school) and the first philosopher in ancient Greece since it was recorded in literature. Thales was a businessman in his early years. He traveled to Babylon, Egypt and other places, where he soon learned the knowledge of mathematics and astronomy. Later, he engaged in political and engineering activities, studied mathematics and astronomy, and turned to philosophy in his later years. He set foot in almost all fields of human thought and activities at that time, and gained a high reputation, known as "the head of the seven sages of Greece". In fact, among the seven sages, only he is a profound scholar, and the rest are politicians. Thales thinks that water is the origin of the world. He has a famous saying: "water is the source of all things, and everything will end with water." Thales did not leave a complete biography. There are many anecdotes about him in history. Describing this character from various angles reflects his life story to some extent. These legends may not be completely true, but they are commensurate with his character. It is said that once he accidentally fell into a puddle while walking and thinking. A handmaid laughed at him and said, "It's ridiculous that you can't even see the things around you, but you always think about those useless things." In this regard, Thales can't refute it at the moment. In fact, Thales later refuted the vulgar handmaid with practical actions. He looked at the sky at night and knew that there would be a bumper harvest of olives in the coming year. He rented all the local oil plants in advance. Sure enough, his knowledge didn't deceive him-olives were harvested. So Terez rented the oil mill at a high price and made huge profits. Thales' behavior proves that it is easy for a philosopher to get rich, but his ambition is not here. Just like his motto above: "Others live to eat, and I eat to live." [Intimate whisper] This story about Thales has been heard many times. I always resent the philosopher's temporary silence. Aristotle's comments on this matter are really comforting. He said: "It is easy for a philosopher to make money, but his interest is not here." Hegel's comment is even more rude: "Only those who lie in the pit forever and don't look up at the sky will not fall into the pit." A philosopher is a philosopher after all. What a wonderful speech! When some people still laugh at some respectable thinkers with the phrase "You can't even see things around you, but you always think about useless things", I think it is an insult to thinkers. I think they are like sardines in cans and bottles, which are quickly brought to the table to eat, digest and excrete, because their life is this procedure; Eat, sleep and die, all the joys and sorrows are in these three words, except giving up the right to think; I just forgot that true happiness always comes from people's hearts. They don't know why they come and go, they only know how to ask for it, but they never think about who they are asking for. Only accept the so-called inhuman moral shackles, but let your divinity gradually lose.
