Socrates
The Metropolitan Museum of Art in New York.
This painting, The Death of Socrates, by the 18th-century artist, David, portrays the famous story of Socrates' death. He was convicted of religious heresy and contamination of the youth and died by drinking hemlock after the people of Athens turned against him.

The citizens of Athens were fed up with the old "wise" man.

Socrates, one of ancient Greece's most learned philosophers, found himself on trial for his teachings. The prosecution accused Socrates of corrupting the youth of Athens. A jury of hundreds found Socrates guilty and sentenced him to death.

At the age of 70, Socrates willingly drank hemlock, a powerful poison that put an end to his controversial life. How did it happen that Athenians put to death a great philosopher such as Socrates?

School of Athens
In the Renaissance artist, Raphael's School of Athens, Plato (shown on the left) argues that one should search for truth from above, while his pupil Aristotle argues that answers can be found through observation on Earth.

Throughout his entire life, Socrates questioned everything from Athenian government to Greek religion and the gods themselves. His ultimate goal was finding the truth, which he believed could be reached through reason and knowledge. Socrates was a teacher, but he did not have a classroom, any books, or even a school. Instead, Socrates lectured publicly. Anyone interested in what he had to say was invited to listen.

Socrates practiced a style of teaching that has since become known as the Socratic method. Essentially, Socrates taught through questioning. He started with simple questions, then progressed to more complex, deeper questions. Through the application of reason and logic, Socrates revealed answers to many questions that led to a greater understanding of the world.

Problems arose because Socrates often questioned the very fundamentals and traditions of Greek society. His constant questioning and searching for the truth were seen as dangerous by many and ultimately led to his death.

Plato's Republic

Plato, a student of Socrates, also achieved greatness as a philosopher. Unlike Socrates, however, Plato chose to write his ideas down. In one of his most renowned works, The Republic, Plato outlined his vision of the ideal state.

Greek philosophy
Greek philosophers were quite prolific, and left behind many wonderful dialogues on life, morality, death, and religion.

Surprisingly, Plato's republic was not very democratic. Plato was greatly disturbed at the way the mass of Athenians had agreed to put to death his brilliant teacher and mentor, Socrates. Plato believed that uneducated people should not have right to make important decisions for everyone.

Instead, Plato envisioned a society with many classes in which each class contributed what it could. In his ideal society, farmers grew the food for the republic, soldiers defended the republic, and a class of intelligent, educated philosophers ruled the republic. Not surprisingly, Plato lived at a time when democratic society in Athens was in decline.


Such then, I said, are our principles of theology --some tales are to be told, and others are not to be told to our disciples from their youth upwards, if we mean them to honour the gods and their parents, and to value friendship with one another.

Yes; and I think that our principles are right, he said.

But if they are to be courageous, must they not learn other lessons besides these, and lessons of such a kind as will take away the fear of death? Can any man be courageous who has the fear of death in him?

Certainly not, he said.

And can he be fearless of death, or will he choose death in battle rather than defeat and slavery, who believes the world below to be real and terrible?

Impossible.

Then we must assume a control over the narrators of this class of tales as well as over the others, and beg them not simply to but rather to commend the world below, intimating to them that their descriptions are untrue, and will do harm to our future warriors.

That will be our duty, he said.

Then, I said, we shall have to obliterate many obnoxious passages, beginning with the verses...Plato, "The Republic," (360 B.C.E.), Book III excerpt, translated by Benjamin Jowett

One of Plato's students, Aristotle, also distinguished himself as a thinker. Aristotle wrote about and studied many subjects, including biology, physics, metaphysics, literature, ethics, logic, art, and more. He emphasized the importance of observation and the gathering of data.

Although Aristotle made important discoveries in many areas, his explanation concerning the movement of heavenly bodies was wrong. Aristotle believed that the Earth was the center of the universe, and that all heavenly bodies revolved around the Earth. This makes sense from a strictly observational standpoint. Looking up at the sky, it looked to Aristotle like everything (sun, moon, stars) circled the earth. In this case, Aristotle's reliance on observation led him astray. In reality, the Earth revolves on its own axis, causing the illusion of it being the center of everything.

A Golden Age of Thought

Besides the three great philosophers described above, ancient Greece produced many other important thinkers. In the realm of science, Hippocrates applied logic to the field of medicine and collected information on hundreds of patients. His work helped advance people's understanding of the causes of disease and death and swayed people from believing in supernatural reasons.

Greek thinkers applied logic to mathematics as well. Pythagoras deduced multiplication tables as well as the Pythagorean theorem relating to right triangles. Euclid revolutionized the field of geometry, and Archimedes worked with the force of gravity and invented an early form of calculus.

In the realm of the social sciences, Herodotus, is often credited with being the first modern historian. Another historian, Thucydides, tried to be as objective as possible in reporting the history he recorded.

Many of these advancements and revelations seem obvious by today's standards. But 2,500 years ago, most humans were concerned with providing food and protection for their families and little else. Most of them were ruled by kings or pharaohs who had supreme decision-making power. The Athenian democracy encouraged countless innovative thoughts among its citizens.

To the ancient Greeks, thinking was serious business.
On the Web
Greek Philosophy
Crystalinks offers a brief intro to Greek philosophy. A simple click on "Ancient Greece," however, will take you to even more subjects on Greek culture. Presentations of Archimedes, Aristotle, Pythagoras, Plato, Socrates, and other great philosophers can be found at this well-made resource.
Archimedes
The theory of buoyancy, the compound pulley, the Archimedes Screw, and the famous number pi.
Ancient Greece: Aristotle
Aristotle is the father of scientific inquiry. Unlike his contemporaries, he believed that the answers to life's questions were not to be found by looking to the gods, but rather by carefully observing everything. And he did indeed observe everything! He wrote 170 books on a wide variety of topics including astronomy, geology, physics, and even zoology.
Pythagoras of Samos
You may know Pythagoras as the man responsible for the Pythagorean Theorem, but he contributed much more to the world of knowledge than just that important proof. He offered important insights into the areas of astronomy and music as well. This brief webpage offers a nice summary of why Pythagoras is placed among the ranks of the great thinkers of Greece.
Archimedes Homepage
Although Archimedes is remembered for many of his mechanical inventions and ideas — such as the theory of buoyancy, the compound pulley, and the Archimedes Screw — he believed that the only worthy pursuit was mathematics. Indeed, he made important advancements in the field. For example, he discovered pi. Not cherry or apple, but the mathematical pi which has been vital to mathematicians ever since. Read more about this brilliant man — his life, his contributions, and his untimely death.
Map of the Acropolis of Athens in Socrates and Plato's Time
Imagine the paths that Socrates and Plato walked with a full-color layout of the Acropolis as it looked during the time of these two great philosophers. Everything on the map is labeled, with descriptions and informative links for each of the buildings, shrines, and theaters in this truly amazing Greek stronghold.
Hippocrates
He is the man that single-handedly changed the face of Western medicine. Hippocrates scoffed at the claims that illnesses were caused by magic or spirits. Instead, he taught that each patient should be treated individually, and to closely observe their symptoms. For the thoughts of Hippocrates on how the body worked, don't miss this link.
Socrates: Philosophy's Martyr
When Socrates took his own life in prison by drinking hemlock, a poison, he insured himself a place in the annals of history as one of philosophy's greatest martyrs. A martyr is one who chooses death over a compromise of his or her principles. Socrates was charged with introducing new gods and corrupting the young. He felt he had merely stayed true to his virtues. Read some excerpts from the book Socrates: Philosophy's Martyr about his trial, and how Socrates measured up to his equally famous student, Plato.
Greek Mathematics and Its Modern Heirs
For an entire millennia, from the 5th century B.C.E. to the 5th century C.E., Greeks were on the leading forefront of discovery in mathematics, astronomy, and the sciences. Shown here are actual texts displayed or retranslated, such as Euclid's Elements, or Archimedes' Works. This is a fascinating page, even if only to look at the original copies of Greek mathematical and scientific thought.
