Parmenides, Socrates, Plato, Heraclitus, and Democritus.
The philosophies of Parmenides (being is unchanging) and Heraclitus (being is ceaselessly changing) seem to be irreconcilably opposed.
Parmenides argued that change is an illusion and that reality is unchanging and unified, while Heraclitus believed that change is fundamental to the nature of reality and that everything is in a state of constant flux. They both made significant contributions to early Greek philosophy by exploring and debating the nature of identity and change.
Plato's theory of forms was influenced by the teachings of his mentor, Socrates, and also drew upon ideas from Parmenides and Pythagoras. It is believed that these various sources combined to form Plato's unique theory of forms, which he articulated in his dialogues such as the "Republic" and the "Phaedo."
It is subjective to determine which Pre-Socratic philosopher had the most compelling ideas as their perspectives varied greatly. However, some key figures like Heraclitus, Parmenides, and Democritus made significant contributions to early philosophical thought.
Parmenides was an ancient Greek philosopher who believed in the unity and immutability of existence. He argued that change and plurality are illusions, and that true reality is a single, unchanging, and eternal entity. Parmenides' philosophy influenced the development of metaphysics and epistemology in Western thought.
Some well known characters in Roman Philosophy are Thales, Heraclitus, Xenophanes, Parmenides, Zeno of Elea and Pluralists. All of these characters lived in the year 500 BCE.
