Plato, a great philosopher in ancient Greece, was born in Athens from 428 to 423 BC until his death in 348 BC. He is regarded as the founder of Western philosophy and an innovator of literary dialogue and dialectics. He has a profound influence on the thinking of later generations. Plato's foundational work not only covered theoretical philosophy, but also went deep into various important issues in practical philosophy, and deeply explored the nature of human existence.
Plato's famous contribution is the "Theory of Ideas", which was later widely interpreted as a solution to the "universal problem".
Plato's life is filled with interactions with prominent philosophers of his time. He was one of the essential wise men of ancient Greece, and his works still resonate in intellectual circles today. Plato's works have been handed down almost intact during his lifetime and 2,400 years after his death. Although its popularity fluctuates, it can still continue to attract readers from different eras to study and think. His philosophical thoughts also had an important influence on the development of Christian and Islamic philosophy.
Alfred North Whitehead once described: "The safest general feature of the European philosophical tradition is that it consists of a series of commentaries on Plato."
Plato's birthplace is generally believed to be in Athens or Aegina. He was born into an influential aristocratic family. His father was Ariston, a nobleman from ancient Athens, and his mother was a descendant of Sauron, a famous politician in ancient Greece. Plato's philosophical career began at the age of 40 when he founded the Academy of Athens, one of the earliest institutions of higher learning in the world at that time. Within the academy, Plato made innovative contributions to the understanding of human existence, the pursuit of truth, and the discussion of interpersonal relationships.
In Plato's dialogues, he often used his important student Socrates as the main character to explore profound issues such as metaphysics, ethics, and politics. His famous "idea" theory explains that the real world can only be understood through reason rather than through the senses. His ideas are divided into two realms: the perceptual world and the ideal world. The objects in the perceptual world are just images of the ideal world.
Plato's idea theory believes that the existence of all objects depends on the ideas that exist behind them, and these ideas are eternal and unchanging.
In terms of epistemology, Plato’s definition of knowledge is unique. He believed that knowledge should be regarded as "justified true belief" and emphasized that this knowledge must rely on the understanding of metaphysical principles. He criticized those cognitive paradigms that relied too much on the senses and advocated that real knowledge lies in grasping unchanging ideas and the relationships between them.
In terms of morality, Plato focuses on the connection between virtue and knowledge. He explored concepts such as virtue, joy, and justice in many dialogues, and elaborated on the definition of justice in his book The Republic. He believes that true justice comes from the understanding of "goodness", and this understanding can guide people to pursue social harmony.
Plato's political theory went a step further and advocated the concept of "philosopher kings", that is, the wisest people should govern the country.
In terms of political structure, Plato advocated that society should have three specific classes: dedicated practice, guardianship and governance. Each class corresponds to a different part of the human soul, a nuanced way of thinking that still holds true in today’s political discussions.
Plato's influence spanned all fields, including literature, art, and science. His ideas not only inspired several later philosophers, but also promoted the development of Western thought as a whole. Especially in the Middle Ages, the fusion of Christian philosophy and Platonism further deepened the understanding of the world.
During the Renaissance and Enlightenment era, many scholars combined Plato's ideas with modern ideas and continued to explore truth and the meaning of existence.
Even in contemporary times, many of Plato's thoughts, such as the discussion of ideal theory and moral development, are still hot topics for philosophers and scholars. His dialogue system promoted the development of critical thinking and has a profound influence on debate and the humanities and social sciences.
Plato’s shaping of Western thought has undeniably become the cornerstone of today’s ideological system. On the contrary, it makes us think: In this rapidly changing world, can Plato’s ideas still remind us to seek the unchanging truth?
