Pre-SocraticPhilosophers
Greek thinkers who developed independent and original schools of thought from the time of Thales of Miletus (l. c. 585 BCE) to that of Socrates of Athens (470/469-399 BCE)
ThalesofMiletus
The first man who coined the word "philosophy"
He challenged the traditional Greek view of religion, mythology, and superstition as an explanation for the universe and its contents
He believed the Earth floats on water and all things come to be from water
Anaximander
He thought there was something called the "apeiron", which means the infinite or boundless, that created everything in the universe in a systematic way
He suggested that living things changed over time to fit their surroundings, like the idea of evolution
Anaximenes
He considered air as the primary element, or the First Cause, behind the existence of all things
He believed air could change its form by becoming denser or rarer, which led to the creation of different substances and phenomena
Pythagoras
A mathematician and scientist who formulated the Pythagorean theorem
He believed that numbers and mathematics were the ultimate truth behind everything
He believed in the idea of reincarnation
Heraclitus
He proposed that everything that exists is based on a higher order or plan which he called logos, and fire forms the basic material principle of an orderly universe
He taught that everything was in flux, constantly changing
Parmenides
Founder of Eleatic School of thought
He believed in Monism: the idea that everything in the world is made of one substance that is unchanging and eternal
He argued that change is just an illusion because the true essence of reality remains constant
Empedocles
He disagreed with the idea that change was just an illusion and thought diversity was the fundamental aspect of existence
He reintroduced the traditional Greek concept of the four elements: water, air, fire, and earth and added the notions of strife and love as forces driving change
Leucippus
He and his student Democritus proposed the idea of atoms, which are tiny, indivisible particles that make up everything in the universe
This led to the belief that fate was more powerful than free will because human life is governed by the continual change of atoms
Aristotle
He considered Thales to be the first philosopher and his philosophical predecessor
He believed that Thales may have thought the world came from water because everything contains moisture
He attended Plato's Academy and was a prominent student and teacher
Democritus
He proposed that everything in the universe is made up of tiny, indivisible particles called atoms, which are the fundamental building blocks of matter
Socrates
He was credited with formulating the Socratic method, a means of examining a topic by devising a seriesofquestions that let the learner examine and analyze his knowledge and views
Plato

His most significant ideas included his TheoryofForms and the dialecticmethod
DiogenesofSinope
He is considered one of the founders of Cynicism, a philosophical school that emphasized living a simple life in accordance with nature and rejecting social conventions and material possessions
