In the history of western education, ancient Greece (Plato) was the first person to put forward the idea of preschool education.

Plato was the greatest philosopher in ancient Greece.

Plato (427- 347 BC), Plato is one of the greatest philosophers and thinkers in western culture, and is also called the three saints of Greece with Plato, Socrates and Aristotle.

The word Plato means "flat and broad" in Greek. Just like Plato's thought, Plato advocated objective idealism, believing that the objective spirit existed before the objective material world, that is to say, the objective spirit is the origin of the world, with spirit first and material later. The objective idealism represented by Plato holds that human consciousness and matter exist independently of each other.
