For, if it is true to say that in essence the tragic hero is intent upon claiming his whole due as a personality, and if this struggle must be total and without reservation, then it automatically demonstrates the indestructible will of man to achieve his humanity. The possibility of victory must be there in tragedy. Where pathos rules, where pathos is finally derived, a character has fought a battle he could not possibly have won. The pathetic is achieved when the protagonist is, by virtue of his witlessness, his insensitivity or the very air he gives off, incapable of grappling with a much superior force. Pathos truly is the mode for the pessimist. But tragedy requires a nicer balance between what is possible and what is impossible. And it is curious, although edifying, that the plays we revere, century after century, are the tragedies. In them, and in them alone, lies the belief--optimistic, if you will, in the perfectibility of man. It is time, I think, that we who are without kings, took up this bright thread of our history and followed it to the only place it can possible lead in our time--the heart and spirit of the average man.
The most important areas of Greek achievement were math and science. They achieved all kinds of things in the areas of psychology, astronomy, geometry, biology, physics, and medicine. In astronomy they formulated the ideas that the sun was 300 times larger than the earth, the universe was composed of atoms, and they calculated the true size of the earth. Someone greatly involved in astronomy was Aristotle. In geometry, ancient Greeks found the value of pi, and a man named Euclid, who wrote the book Elements around 300 ., theorized that if two straight lines cut one another, the vertical, or opposite, angles shall be equal. In physics, the lever and pulley was invented along with a force pump which eventually evolved into a steam engine. Important people in this area were Archimedes and Pythagoras who were two of the many influential Greek citizens. Ancient Greece has definitely made many influential contributions to western civilization.
