they become hesitant. By the end of these dis-
courses, the value of independent thinking and the
unrelenting pursuit of truth have been brought to
light.
In other discourses, the dialogues often end in-
conclusively since, according to Plato, the purpose
of reason—a faculty that only humans possess—is
to strive toward definition with disciplined think-
ing and to illuminate the natural world, not to
limit its possibilities. This philosophy can be seen
in some of the works Plato produced during his
years of self-imposed exile and travel: Lysis, which
asks, “What is friendship?”; Euthyphro (“What is
piety?”); Charmides (“What is temperance?”); and
Theatetus (“What is knowledge?”).
In the 380s B.C., Plato returned to Athens to es-
tablish the school that would become known as the
Academy, which emphasized pure research and
discourse on the topics of mathematics, astronom-
ical disciplines, government, natural sciences, and
rhetoric. Plato spent two decades of his life as an
educator and director of the Academy. It was most
likely during this time that he produced the bulk of
his 29 treatises. Among these were The Symposium,
which takes place at a banquet whose guests, in-
cluding Plato’s friend ARISTOPHANES, attempt to de-
fine love; The Republic, Plato’s magnum opus; and
Phaedo, purportedly an account of the exchange
between Socrates and his followers and friends on
the eve of his execution. (In reality, due to illness,
Plato was not among Socrates’ visitors.) During
the exchange, Socrates explains that the philoso-
pher should not fear death, as he does not, because
only without the burden of corporeal form can the
eternal soul come to know the pure truth and
splendor that mortal beings seek during their ex-
istence on earth.
In the late 360s
B.C., Plato twice visited Diony-
sius II, the “tyrant of Syracuse,” to put to the test
his theories regarding the education of philoso-
pher-kings as described in The Republic, and to
persuade the ruler to implement a platonic gov-
ernment. Plato’s ambitions were not realized, and
he returned to the Academy, where he remained
until his death.
Critical Analysis
Contained in 10 books, The Republic is Plato’s
longest finished work; Professor Allan Bloom’s
seminal translation runs 300 pages long. Appear-
ing initially to be an inquiry into the nature of jus-
tice, the discourse soon turns toward an attempt to
define and describe a “just man” and a “just city.”
Ultimately, the soul of the just man is shown to be
a microcosm of the operations of a just state.
Early in the dialog, Socrates and his interlocu-
tors deduce how a city comes about:
[It] comes into being because each of us isn’t
self-sufficient but is in need of much....So,
then, when one man takes on another for one
need and another for another need, and, since
many things are needed, many men gather in
one settlement as partners and helpers, to this
common settlement we give the name city,
don’t we?
(II.369b–c)
In essence, Plato is saying that no one can provide
entirely for himself; a city needs farmers, house
builders, weavers, shoemakers, carpenters, herds-
men, merchants, and laborers. But life would be
bleak without luxuries such as olives, furniture,
perfumes, embroidery, and ivory. Therefore many
more people are needed, including poets, servants,
beauticians, and chefs.
The dramatis personae agree with Socrates that
“each of us is naturally not quite like anyone else,
but rather differs in his nature; different men are
apt for the accomplishment of different jobs”
(II.370a–b). They also agree that it is appropriate
for one person to practice one art rather than
many arts.
The philosophical discussion of The Republic
then leads the characters to deduce that the exis-
tence of valuables in the city will lead to crime,
which in turn creates a need for military forces.
The “origin of war,” says Socrates, lies “in those
things whose presence in cities most of all pro-
duces evils both private and public” (II.373e). The
characters’ final conclusion regarding the forma-
