Taylor (θ α λ? 6? 8? 0? Thales, who lived around 585 BC, was an ancient Greek philosopher, one of the seven sages of ancient Greece and the founder of Miletus School. Born in the prosperous port city of Milai, Greece, it is said that he traveled to Egypt and other places, measured the height of the pyramids and successfully predicted an eclipse.

Taylor believes that everything is made up of water, and water is the source of everything. This view may be formed by seeing the process of seawater evaporation. According to legend, his motto is "Water is the best". Taylor also declared that "everything has a God". Taylor had an important influence on Greek philosophy. It is said that anaximander is his student. There is also a legend that Pythagoras visited Taylor in his early years and followed his advice and went to Egypt for research.

Heraclitus (about 540 ~ 480 BC) was an ancient Greek philosopher and the founder of the Eiffel School. Born in Eiffel, a noble family. His article is obscure and full of metaphors. Heraclitus' theory is based on Pythagoras' theory. He borrowed Pythagoras' concept of "harmony" and thought that there was a certain degree of harmony behind opposition and conflict, but coordination itself was not noticeable. He believes that conflict makes the world full of vitality. Heraclitus also believes that fire is the source of all things. "Everything is replaced by fire, and fire is also replaced by everything." Heraclitus also believes that everything is fluid and everything is constantly changing. His famous saying is: "People can't step into the same river twice, because this river is different from this person." Socrates therefore called Heraclitus a "wanderer". Heraclitus' theory of opposition points out that everything in the world is relative, and it is impossible to understand good without understanding evil. Heraclitus thinks that God is something that covers the whole world. But he often replaces God with logos (that is, reason). He believes that there is "universal reason" in the world to guide everything that happens in nature.

Pythagoras (Greek ∈υθ α γ? 0? 2ρα? 0? 9,580-500 years ago), an ancient Greek philosopher, mathematician and music theorist. Born in Samos Island, he traveled to Egypt in his early years, then settled in Croton, a city in southern Italy, and established his own club. In 5 10 BC, Pythagoras moved to Medapenton again because of the rebellion of the opposition until his death. Pythagoras' philosophy is influenced by Oedipus, and there are some mysterious factors. He believes that there are three kinds of people in society, and the soul belongs to the result of reincarnation. But at the same time, from Pythagoras, Greek philosophy began to produce the tradition of mathematics. Pythagoras used mathematics to study music, and the resulting concept of "harmony" also had a great influence on later ancient Greek philosophers. Pythagoras was also the first person to discover Pythagoras theorem (also called Pythagoras theorem in the west).

In cosmology, Pythagoras combined the Miletus school with his own theory of numbers. He thinks that there are many but limited worlds, and insists that the earth is round, but he abandons the geocentric theory of Miletus school. Pythagoras' study of mathematics also produced later idealism and universalism. In other words, there is a difference between being sensible and being sensible. Emotional things are perfect and eternal, and emotional things are flawed. This thought was carried forward by Plato and has ruled philosophy and theology since then.

Socrates (Greek: ∑ρρ? 0? 4τη? 0? 9 (469 BC-399 BC) was a famous philosopher in ancient Greece. Aristotle, one of his students, is a student of Plato and Plato, also known as the "three sages of Greece". Born in the golden age of Athens ruled by Pei Ricqles, he died in the decline of Athens. (the period after the fall of the thirty tyrants after the Peloponnesian War). Born in poverty, my father is a sculptor and my mother is a midwife. Socrates is a historical figure with distinctive personality, full of legend and mixed comments. Socrates is Plato's teacher He didn't write all his life, and his remarks and thoughts were mostly found in Plato's and Xenophon's works, such as Socrates' Words and deeds. Socrates was finally forced to drink poisonous violet juice and died because he violated the interests of the powerful people at that time. His career has long depended on education. Socrates' teaching method is unique, and he often educates by inspiring and debating. Socrates is the founder of Plato's philosophical line. Socrates attached importance to ethics and was the first person in ancient Greece who proposed to find universal morality with reason and thinking. He is the founder of moral philosophy. He emphasized that morality is guided by reason, so "virtue is knowledge" and thought that good comes from knowledge and evil comes from ignorance. In the history of European philosophy, firstly, the teleology of idealism was put forward, which believed that everything was created and arranged by God and reflected God's wisdom and purpose. Put forward the proposition of "knowing your own ignorance", and think that only those who give up the pursuit of nature (because it is God's territory) and admit their ignorance are smart people. The most knowledgeable person is God, and knowledge ultimately comes from God. True knowledge is obedience to God. In logic, Aristotle thinks that Socrates puts forward inductive argument, finds out definite arguments from concrete facts, and pays attention to accurately explaining concepts by means of general definition. Socrates' philosophy mainly thinks that there are standards for right and wrong. It is said that Socrates' family life is unfortunate and his wife is a bitch.

Plato (Greek: ∏ λ? 0? 4, English: Plato, about 427- 347 BC) was an ancient Greek philosopher, whose main philosophical thought was idealism, which had a great and far-reaching influence on western philosophical thought. Formerly known as Ali Stoertz, he is the fourth in the family. Plato was nicknamed by his PE teacher. He is a student of Socrates and a teacher of Aristotle. The Republic is his most important work. Plato was born in Athens and received a good aristocratic education. At the age of about twenty, he began to follow Socrates. In 399 BC, Socrates was tried and sentenced to death, and Plato fled to Megara for refuge. Later, he traveled everywhere, including Sicily, southern Italy, Egypt and other places. In 387 BC, Plato returned to Athens and founded the Academy. The name of the college is related to the address of the college, and the location of the college is related to the legendary Greek Heroes College, hence the name. Academy is the earliest teaching institution in the West and the predecessor of the developed universities in the Middle Ages. The college existed for more than 900 years until it was closed by Justinian the Great in 529 AD. The college is greatly influenced by Pythagoras, and its curriculum is similar to the traditional topics of Pythagoras school, including arithmetic, geometry, astronomy and acoustics. In 367 BC, Plato traveled again. At this time, the college has been established for more than 20 years. He came to Syracuse to put his ideas into practice, but was forced into exile. In 360 BC, he returned to Athens and continued to teach and write in the college. Plato's main philosophical thoughts are recorded in the form of dialogue. In Plato's dialogues, there are many dialogues in the name of Socrates, so it is difficult to distinguish Socrates' thoughts from Plato's.
