The charge made against Socrates -- disbelief in the state's gods -- implied un-Athenian activities which would corrupt the young and the state if preached publicly. Meletus, the citizen who brought the indictment, sought precedents in the impiety trials of Pericles' friends. Although Socrates was neither a heretic nor an agnostic, there was prejudice against him. He also managed to provoke hostility. For instance, the Delphic oracle is said to have told Chaerephon that no man was wiser than Socrates. During his trial Socrates had the audacity to use this as a justification of his examination of the conduct of all Athenians, claiming that in exposing their falsehoods, he had proved the god right -- he at least knew that he knew nothing. Although this episode smacks of Socrates' well-known irony, he clearly did believe that his mission was divinely inspired.

The political and social upheaval caused by the Persian Wars as well as continued strife between Athens and Sparta (see Lecture 7) had at least one unintended consequence . In the 5th century, a flood of new ideas poured into Athens. In general, these new ideas came as a result of an influx of Ionian thinkers into the Attic peninsula. Athens had become the intellectual and artistic center of the Greek world. Furthermore, by the mid-5th century, it had become more common for advanced thinkers to reject traditional explanations of the world of nature.

Furthermore, by the mid-5th century, it had become more common for advanced thinkers to reject traditional explanations of the world of nature. As a result of the experience of a century of war, religious beliefs declined. Gods and goddesses were no longer held in the same regard as they had been a century earlier. I suppose we could generalize and say that the Persian and Peloponnesian Wars taught that the actions of men and women determine their own destiny, and not "Moira." Meanwhile, more traditional notions of right and wrong were called into question, and all of this was expressed in Hellenic tragedy and comedy.

The Greeks used their creative energies to explain experience by recourse to history, tragedy, comedy, art and architecture. But their creative energies were also used to "invent" philosophy, defined as "the love of wisdom." In general, philosophy came into existence when the Greeks discovered their dissatisfaction with supernatural and mythical explanations of reality. Over time, Greek thinkers began to suspect that there was a rational or logical order to the universe.

Fire is the primordial element out of which all else has arisen -- change (becoming) is the first principle of the universe. Cratylus, a follower of Heraclitus, once made the remark that "You cannot step twice into the same river." The water will be different water the second time, and if we call the river the same, it is because we see its reality in its form. The logical conclusion of this is the opposite of flux, that is, a belief in an absolute, unchanging reality of which the world of change and movement is only a quasi-existing phantom, phenomenal, not real.

Democritus of Abdera (c.460-370 B.C.) argued that knowledge was derived through sense perception -- the senses illustrate to us that change does occur in nature. However, Democritus also retained Parmenides' confidence in human reason.

It is also necessary to point out that Thales committed none of his views to writing. Anaximander of Miletus (c.611-c.547 B.C.), another Milesian thinker, rejected Thales, and argued instead that an indefinite substance -- the Boundless -- was the source of all things. According to Anaximander, the cold and wet condensed to form the earth while the hot and dry formed the moon, sun and stars. The heat from the fire in the skies dried the earth and shrank the seas. It's a rather fantastic scheme, but at least Anaximander sought natural explanations for the origin of the natural world.

His universe consisted of empty space and an infinite number of atoms (a-tomos, the "uncuttable"). Eternal and indivisible, these atoms moved in the void of space. An atomic theory to the core, Democritus saw all matter constructed of atoms which accounted for all change in the natural world.

He was a good citizen but held political office only once – he was elected to the Council of Five Hundred in 406 B.C. In Plato's Apology, Socrates remarks that:

-
The true champion if justice, if he intends to survive even for a short time, must necessarily confine himself to private life and leave politics alone.
-
Socrates was not an attractive man -- he was snub-nosed, prematurely bald, and overweight. But, he was strong in body and the intellectual master of every one with whom he came into contact. The Athenian youth flocked to his side as he walked the paths of the agora. They clung to his every word and gesture. He was not a Sophist himself, but a philosopher, a lover of wisdom.
-
n 399 B.C., Socrates was charged with impiety by a jury of five hundred of his fellow citizens.
-
charge made against Socrates -- disbelief in the state's gods -- implied un-Athenian activities which would corrupt the young and the state if preached publicly.

Plato established a school at Athens for the education of Athenian youth. The Academy, as it was called, remained in existence from 387 B.C. to A.D. 529, when it was closed by Justinian, the Byzantine emperor.
-
A Socratic dialogue takes the form of question-answer, question-answer, question-answer. It is a dialectical style as well. Socrates would argue both sides of a question in order to arrive at a conclusion. Then that conclusion is argued against another assumption and so on. Perhaps it is not that difficult to understand why Socrates was considered a gadfly

Aristotle lectured on astronomy, physics, logic, aesthetics, music, drama, tragedy, poetry, zoology, ethics and politics. The one field in which he did not excel was mathematics. Plato, on the other hand, was a master of geometry.
-
Plato's greatest students ought to have also been his greatest critics. Like Democritus, Aristotle had confidence in sense perception.

new ideas poured into Athens
-
The Greeks used their creative energies to explain experience by recourse to history, tragedy, comedy, art and architecture.
-
Over time, Greek thinkers began to suspect that there was a rational or logical order to the universe.
-
Around 600 B.C., Milesian thinkers "discovered" speculation after asking a simple but profound question: "what exists?" It was the Ionian natural philosopher, Thales of Miletus (c.624-548 B.C.),
-
who answered that everything in the universe was made of water and resolves itself into water
-
It is also necessary to point out that Thales committed none of his views to writing. Anaximander of Miletus (c.611-c.547 B.C.), another Milesian thinker, rejected Thales, and argued instead that an indefinite substance -- the Boundless -- was the source of all things. According to Anaximander, the cold and wet condensed to form the earth while the hot and dry formed the moon, sun and stars.
-
The Pythagoreans, who lived in Greek cities in southern Italy, discovered that the intervals in the musical scale could be expressed mathematically and that this principle could be extended to the universe.
-
We "know" reality not by the senses, which are capable of deception, but through the human mind, not through experience, but through reason. As we shall see, this concept shall become central to the philosophic thought of Plato.
-
Perhaps the most important of all the Pre-Socratic philosophers was Heraclitus of Ephesus (fl. 500 B.C.). Known as "the weeping philosopher" because of his pessimistic view of human nature and "the dark one" because of the mystical obscurity of his thought, Heraclitus wrote On Nature, fragments of which we still possess.
-
Fire is the primordial element out of which all else has arisen -- change (becoming) is the first principle of the universe. Cratylus, a follower of Heraclitus, once made the remark that "You cannot step twice into the same river.
-
Democritus of Abdera (c.460-370 B.C.) argued that knowledge was derived through sense perception -- the senses illustrate to us that change does occur in nature. However, Democritus also retained Parmenides' confidence in human reason.
-
atoms (a-tomos, the "uncuttable"). Eternal and indivisible, these atoms moved in the void of space. An atomic theory to the core, Democritus saw all matter constructed of atoms which accounted for all change in the natural world.
-
Hippocrates of Cos (c.460-c.377 B.C.) was able to distinguish between magic and medicine. Physicians observed ill patients, classified symptoms and then made predictions about the course of a disease.
-
Into such an atmosphere of change came the traveling teachers, the Sophists. The Sophists were a motley bunch – some hailed from the Athenian polis or other city-states, but the majority came from Ionia, in Asia Minor.
-
The Sophists abandoned science, philosophy, mathematics and ethics. What they taught was the subtle art of persuasion. A Sophist was a person who could argue eloquently – and could prove a position whether that position was correct or incorrect. In other words, what mattered was persuasion and not truth.
-
According to Protagoras (c.485-c.411 B.C.), "Man is the measure of all things." Everything is relative and there are no values because man, individual man, is the measure of all things. Nothing is good or bad since everything depends on the individual.
-
Gorgias of Leontini (c.485-c.380 B.C.), who visited Athens in 427, was a well-paid teacher of rhetoric and famous for his saying that a man could not know anything. And if he could, he could not describe it and if he could describe it, no one would understand him.
-
The Sophistic movement of the fifth century B.C. has been the subject of much discussion and there is no single view about their significance. Plato's treatment of the Sophists in his late dialogue, the Sophist, is hardly flattering. He does not treat them as real seekers after truth but as men whose only concern was making money and teaching their students success in argument by whatever means. Aristotle said that a Sophist was "one who made money by sham wisdom."

It is in The Republic that Plato suggests that democracy was little more than a "charming form of government."

In The Republic, Plato asks what is knowledge? what is illusion? what is reality? how do we know? what makes a thing, a thing? what can we know? These are epistemological questions – that is, they are questions about knowledge itself.

There is a reason why Socrates employed this style, as well as why Plato recorded his experience with Socrates in the form of a dialogue.

The Sophists were a motley bunch – some hailed from the Athenian polis or other city-states, but the majority came from Ionia, in Asia Minor. The Sophists were men whose responsibility it was to train and educate the sons of Athenian citizens. There were no formal school as we know them today. Instead, these were peripatetic schools, meaning that the instructor would walk with students and talk with them – for a fee, of course. The Sophists taught the skills (sophia) of rhetoric and oratory. Both of these arts were essential for the education of the Athenian citizenry. After all, it was the sons of the citizens who would eventually find themselves debating important issues in the Assembly and the Council of Five Hundred. Rhetoric can be described as the art of composition, while oratory was the art of public speaking.
-
In his youth he fought as a hoplite at Potidaea (432-429), Delium (424) and Amphipolis (422) during the Peloponnesian Wars. To be sure, his later absorption in philosophy made him neglect his private affairs and he eventually fell to a level of comparative poverty. He was perhaps more in love with the study of philosophy than with his family -- that his wife Xanthippe was shrew is a later tale.
-
I do not accept this opinion. Instead, I would like to suggest that The Republic is not a blueprint for a future society, but rather, is a dialogue which discusses the education necessary to produce such a society.

It perhaps goes without saying that the western intellectual tradition, as well as the history of western philosophy, must begin with an investigation of ancient Greek thought.

Plato argued that reality is known only through the mind. There is a higher world, independent of the world we may experience through our senses. Because the senses may deceive us, it is necessary that this higher world exist, a world of Ideas or Forms -- of what is unchanging, absolute and universal. In other words, although there may be something from the phenomenal world which we consider beautiful or good or just, Plato postulates that there is a higher unchanging reality of the beautiful, goodness or justice. To live in accordance with these universal standards is the good life -- to grasp the Forms is to grasp ultimate truth.
-
In other words, whereas Plato suggested that man was born with knowledge, Aristotle argued that knowledge comes from experience. And there, in the space of just a few decades, we have the essence of those two philosophical traditions which have occupied the western intellectual tradition for the past 2500 years. Rationalism – knowledge is a priori (comes before experience) and Empiricism – knowledge is a posteriori (comes after experience).
-
Aristotle argued that there were universal principles but that they are derived from experience.
-
He could not accept, as had Plato, that there was a world of Forms beyond space and time. Aristotle argued that that there were Forms and Absolutes, but that they resided in the thing itself. From our experience with horses, for instance, we can deduce the essence of "horseness." This universal, as it had been for Plato, was the true object of human knowledge.

What we do know is that his father was Sophroniscus, a stone cutter, and his mother, Phaenarete, was a midwife
-
In his youth he fought as a hoplite at Potidaea (432-429), Delium (424) and Amphipolis (422) during the Peloponnesian Wars.
-
his later absorption in philosophy made him neglect his private affairs and he eventually fell to a level of comparative poverty.
-
Taking no fees, Socrates started and dominated an argument wherever the young and intelligent would listen, and people asked his advice on matters of practical conduct and educational problems.
-
Socrates was that he was remarkable for living the life he preached.
-
In 399 B.C., Socrates was charged with impiety by a jury of five hundred of his fellow citizens.
-
He was convicted to death by a margin of six votes. Oddly enough, the jury offered Socrates the chance to pay a small fine for his impiety. He rejected it.
-
Socrates refused to break the law. What kind of citizen would he be if he refused to accept the judgment of the jury?
-
He spent his last days with his friends before he drank the fatal dose of hemlock.
-
disbelief in the state's gods -- implied un-Athenian activities which would corrupt the young and the state if preached publicly.
-
The reason why this charge is somewhat justified is that he challenged his students to think for themselves – to use their minds to answer questions.
-
He did not reveal answers. He did not reveal truth
-
as that most people could not answer these fundamental questions to his satisfaction, yet all of them claimed to be courageous, virtuous and dutiful.
-
Socrates knew, was that he knew nothing, upon this sole fact lay the source of his wisdom.
-
Socrates wrote nothing himself. What we know of him comes from the writings of two of his closest friends, Xenophon and Plato.
-
PLATO (c.427-347 B.C.) came from a family of aristoi, served in the Peloponnesian War, and was perhaps Socrates' most famous student.
-
At the age of forty, Plato established a school at Athens for the education of Athenian youth. The Academy, as it was called, remained in existence from 387 B.C. to A.D. 529, when it was closed by Justinian, the Byzantine emperor.
-
Plato's dialogue is important – it is the Socratic style that he employs throughout. A Socratic dialogue takes the form of question-answer, question-answer, question-answer.
-
one of the things Plato more or less discovered on his own was that mankind is born with knowledge.
-
It is not so much that we "learn" things in our daily experience, but that we "recollect" them. In other words, this knowledge is already there.
-
Plato's greatest and most enduring work was his lengthy dialogue, The Republic.
-
Nearly impossible to translate into modern idiom, paideia refers to the process whereby the physical, mental and spiritual development of the individual is of paramount importance. It is the education of the total individual.
-
For Plato, the citizens are the least desirable participants in government. Instead, a philosopher-king or guardian should hold the reigns of power. An aristocracy if you will – an aristocracy of the very best – the best of the aristoi.
-
Plato asks what is knowledge? what is illusion? what is reality? how do we know? what makes a thing, a thing? what can we know? These are epistemological questions – that is, they are questions about knowledge itself.
-
knowledge of reality is individual, it is particular, it is knowledge only to the individual knower, it is not universal.
-
Plato argued that reality is known only through the mind
-
The unphilosophical man – that is, all of us – is at the mercy of sense impressions and unfortunately, our sense impressions oftentimes fail us.
-
Plato's most famous student was ARISTOTLE (384-322 B.C.).
-
Aristotle was, for a time at least, the personal tutor of Alexander the Great.
-
He too was charged with impiety, but fled rather than face the charges
-
Aristotle was a "polymath" – he knew a great deal about nearly everything.
-
In fact, the books to which Aristotle's name is attributed are really little more than student notebooks.
-
Plato, on the other hand, was a master of geometry.
-
Plato suggested that man was born with knowledge, Aristotle argued that knowledge comes from experience.
-
Rationalism – knowledge is a priori (comes before experience) and Empiricism – knowledge is a posteriori (comes after experience).
-
Aristotle argued that there were universal principles but that they are derived from experience.

-
they had given to nature a rational and non-mythical foundation
-
a critical analysis of theories
-
mythical explanations relied on blind faith alone
-
Physicians observed ill patients, classified symptoms and then made predictions about the course of a disease.
-
Rhetoric can be described as the art of composition, while oratory was the art of public speaking.
-
the subtle art of persuasion
-
The Sophists abandoned science, philosophy, mathematics and ethics.
-
what mattered was persuasion and not truth
-
no such thing as a universal or absolute truth
-
relativists
-
"Man is the measure of all things."
-
Nothing is good or bad since everything depends on the individual.
-
Plato's treatment of the Sophists in his late dialogue, the Sophist, is hardly flattering.
-
He does not treat them as real seekers after truth but as men whose only concern was making money and teaching their students success in argument by whatever means.
-
Socrates
-
his later absorption in philosophy made him neglect his private affairs and he eventually fell to a level of comparative poverty.
-
Taking no fees, Socrates started and dominated an argument wherever the young and intelligent would listen, and people asked his advice on matters of practical conduct and educational problems
-
He was not a Sophist himself, but a philosopher, a lover of wisdom.
-
But Socrates refused to break the law. What kind of citizen would he be if he refused to accept the judgment of the jury? No citizen at all.
-
During his trial Socrates had the audacity to use this as a justification of his examination of the conduct of all Athenians, claiming that in exposing their falsehoods, he had proved the god right -- he at least knew that he knew nothing.
-
Although this episode smacks of Socrates' well-known irony, he clearly did believe that his mission was divinely inspired.
-
Socrates was not necessarily an intelligent man – but he was a wise man.
-
The style of the Plato's dialogue is important – it is the Socratic style that he employs throughout. A Socratic dialogue takes the form of question-answer, question-answer, question-answer.
-
It is a dialectical style as well. Socrates would argue both sides of a question in order to arrive at a conclusion.
-
His job was not to teach truth but to show his students how they could "pull" truth out of their own minds (it is for this reason that Socrates often considered himself a midwife in the labor of knowledge). And this is the point of the dialogues. For only in conversation, only in dialogue, can truth and wisdom come to the surface.
-
It is in The Republic that Plato suggests that democracy was little more than a "charming form of government."
-
For Plato, the citizens are the least desirable participants in government.
-
An aristocracy if you will – an aristocracy of the very best – the best of the aristoi.
-
Because the senses may deceive us, it is necessary that this higher world exist, a world of Ideas or Forms -- of what is unchanging, absolute and universal. In other words, although there may be something from the phenomenal world which we consider beautiful or good or just, Plato postulates that there is a higher unchanging reality of the beautiful, goodness or justice.
-
In other words, whereas Plato suggested that man was born with knowledge, Aristotle argued that knowledge comes from experience.

Democritus of Abdera (c.460-370 B.C.)
-
His universe consisted of empty space and an infinite number of atoms (a-tomos, the "uncuttable"). Eternal and indivisible, these atoms moved in the void of space.
