Pre-Socratic Philosophers:

1. Thales of Miletus (c. 624 – c. 546 BCE):

2. Anaximander (c. 610 – c. 546 BCE):

4. Parmenides (c. 515 – c. 450 BCE):

   • Contributions: Known for his assertion that reality is unchanging and that change is an illusion. His work laid the foundation for the development of metaphysics.

5. Pythagoras (c. 570 – c. 495 BCE):

Classical Philosophers:

1. Socrates (c. 470 – 399 BCE):

   • Contributions: Known for his method of dialectical questioning (Socratic method) to explore ethical concepts. Socrates emphasized the importance of knowledge and virtue and was critical of Athenian democracy.

2. Plato (c. 427 – c. 347 BCE):

   • Contributions: A student of Socrates, Plato founded the Academy in Athens. He wrote dialogues exploring justice, beauty, and equality, and introduced the theory of Forms, proposing that the material world is a shadow of a higher reality.

His works cover a wide range of topics, including logic, metaphysics, ethics, politics, and biology. He introduced the concept of the Golden Mean in ethics and laid the foundation for the scientific method.

Hellenistic Philosophers:

1. Epicurus (341 – 270 BCE):

Late Classical and Hellenistic Philosophers:

1. Diogenes of Sinope (c. 412 – 323 BCE):

Contributions and Influence:

Greek philosophers laid the groundwork for Western philosophy and science. They developed critical methods of thinking, explored fundamental questions about existence, knowledge, and ethics, and their works continue to be studied for their profound insights into human nature and the universe.

Their legacy includes the development of logical reasoning, ethical frameworks, and scientific inquiry that have shaped various disciplines and intellectual traditions throughout history.
