The Pre-Socratics

Cosmologists (also known as 'Materialists')

What is the original substance?
What is the relation between the One and the Many?
Four elements:
air
fire
water
earth
Deductive method
moved from the general to particulars
Goal
objective truth about the cosmos
Speculations of the cosmologists were mutually exclusive
Thales: the cosmos developed out of water
Heraclitus: The cosmos developed out of fire
Anaximenes: The cosmos developed out of air
Lack of final conclusions
lead to a shift of emphasis from object to subject
from cosmos to man himself

Sophists

Focused on man, civilization and culture
Relativistic outlook:
justice varies from one culture to the next
there are many different kinds of virtue
Inductive method
moved from particulars to the general
Goal
practical knowledge about living
Wandering teachers
grammar
philosophy of mythology and religion
rhetoric
Some Sophists:
1. favored conception of 'natural law'
2. broadened outlook of ordinary Greek citizens
3. were an educative force
Sophists as a whole:
1. taught rhetorical manipulation
2. were sceptical of prevailing culture and beliefs
but presented nothing new to replace them
3. unlike older philosophers, took payment

Socrates and Plato

Socrates (born c 470 BCE)

constitution and appearance
abstraction
daimon, 'divine sign'
only told him what not to do
i.e., do not get involved in politics
served one term on Council of 500
served as a hoplite
began by studying cosmologists
literate
read all the books of Anaxagoras
found their arguments unconvincing
and turned to moral and ethical philosophy
wrote nothing
philosophy as thought and conversation

Plato (born 427 BCE)

Aristocratic family
turned away from politics, disillusioned with:
1. the oligarchy of 404-3
2. democracy
Gifted poet and writer
his dialogues are both philosophy and literature
'popular' works
Founded the Academy, 388 BCE (lasted until 6th c CE)
First European university:
philosophy
mathematics
astronomy
physical sciences
Aristotle one of his leading students

Problem of the Dialogues

How much is Socrates, how much is Plato?
Early dialogues more 'Socratic'
Socrates' defense
Apology
Crito
The 'Socratic method'
Euthyphro
Meno
Dialogues which present the 'Forms' are Platonic
Phaedo
Such dialogues build upon Socrates' thought

Euthyphro

Dramatic prologue to the Apology
What is the pious?
Socrates' search for universal definitions
contrasts with the relativism of the Sophists
Socratic Dialectic
Like most of the early dialogues, this one ends without reaching a definition
yet evidence of the Apology suggests that Socrates already had a definition
note that Euthyphro agrees that piety is a kind of service of the gods (13d)

Historical background for the prosecution of Socrates:

1. from Delian League to Athenian Empire
Aegean an Athenian "lake"
2. a defeated and reduced Athens
War with Sparta 431
Pericles' plan
rely on city walls and raid Spartan allies
plague in 430
death of Pericles 429
Aggressive plan
attempt to conquer nearby poleis
Brief peace in 421
Sicilian disaster 415
prosecution of Alcibiades
Revolt of allies, aided by Persia
Spartans cut off Athenian food supply
Unconditional surrender, 404
city walls razed
fleet dismantled
empire gone
A brief period of aristocratic oligarchy
extremely harsh rule
some oligarchs had ties to Socrates
democracy restored
3. a wide-spread suspicion of sophists and other philosophers
prosecution of Anaxagoras c. 450 BCE
wide-spread feeling that philosphers could make "the worse argument appear stronger"

The Apology

A good example of an Athenian court
both a civil and a criminal case
Nature of Socrates' defense
His mission
Delphic oracle: 'No man is wiser than Socrates.' (21a)
may have prompted him to become a street philosopher
Gnothi sauton!
concluded that his wisdom equals a knowledge of his limits
Socrates as 'gadfly' (30e)
claims he has never been a teacher (33a)
Sought to stimulate Athenians into caring for wisdom
"Wealth does not bring about excellence, but excellence makes wealth and everything else good for men, both individually and collectively." (30b)
"Do not care for the city's posessions more than the city itself!" (36c)
This attitude was connected to his avoidance of politics.
tried to avoid opposing people and their interests directly
claims his service to the god is the greatest blessing the city possesses (30a)
implies a definition of piety:
Piety is doing god's work to benefit people.
"The unexamined life is not worth living!" (38a)
It is better to suffer an injustice than to act unjustly.

Crito

Presents Socrates' reasons for abiding by the verdict of the court
his devotion to the polis
his concern for consistency of thought and action
"The most important thing is not life, but the good life" (48b)
the responsibilities of a citizen
escaping would be impious
places polis above oikos and above self
Rejects retaliation and revenge
most Greeks equated justice with retaliation
debate over the fate of Mytilene in 427 BCE
Aristotle (Rhet. 1367a19-20): It is noble to avenge oneself on one's enemies and not to come to terms with them: for retaliation is just and the just is noble . . .
Reasoning in 48b-c
1. One must never do wrong.
2. Therefore, we should never wrong someone who wronged us.
3. We should never injure anyone.
4. If we are injured we should never inflict an injury in return.
5. Injuring people is no different from wrongdoing.
