The Early Greek Philosophers

 

Philosopher

Where & When

Main Argument

 

Thales (13)

Greece, Asia Minor Caost - 585 BC

What is the world made of? Everything comes from water in different forms; water is a life-force; Milesian School

Anaximander (13)

610 BC-546 BC, Miletus

Pupil of Thales; Milesian School; Earth, which is a cylinder that floats like a drum, is suspended in space because it is equidistant from everything else; didn’t agree with Thales that Earth was made of water. 

Anaximenes (13)

 

Asia-Minor, 610 BC

Milesian School; Earth was flat – like lid on a boiling saucepan. Earth was supported by something; influenced the Pythagoreans

Heraclitus (14)

 

Asia-Minor, 610 BC

Opposites don’t exist; they are two halves of the same thing; glass half full= glass half empty; UNITY of OPPOSITES; beginning to explain the nature of things

Pythagoras (15)

 

570 BC – 497 BC, Samos

Mathematics has a role in the understanding of the world; everything in the world can be calculated; math is the logical reason for the ways of the worlds – he brought Math & Philosophy together - came up with the word Philosophy (love of wisdom);

Xenophanes (15)

 

Crete, 6th Century BC

All knowledge can be replaced by something else; knowledge changes over time; truth changes; “As for certain truth, no man has known it.”

 

Parmenides (16)

 

5th Century BC – Southern coast of Italy

Nothing has not, cannot, will not exist; invented the conservation of mass; there doesn’t necessarily have to be a beginning; first expression of the idea “eternal” Everything has always existed.

 

Empedocles (17)

 

 

5th Century BC - Sicily

Thought he was immortal; matter cannot come from nothing and go into nothing; four basic elements: earth, water, air, fire; believed that there were two different forces: love (brought stuff together), strife (drove things apart)  Threw himself into a volcano!

Lucipus & Democritus (18)

 

5th Century BC, Thrace

The “Atomists.’  Everything is made up of atoms that are too small to be seen and subdivided; all change in the universe relates to atoms; made no attempt to explain natural phenomenon

Anaxagoras &Protagoras (18)

 

Athens, 5th Century BC

Introduced philosophy to Athens; wanted to understand the nature of the world around them; theorized on the largest possible scale; “Man is the measure of all things” – view of what is important changes from the world to man – Bridge between Pre-Socratics and Socrates/Plato/Aristotle
