2. Business
• Blogging – after class, and before the
weekend, write a reflective post about the
week
– Does everyone know what a post is?
• Don’t let this sit . . . Do it before you begin
next week’s readings
9. Plato
• Plato’s cave is an allegory of knowledge
– Describes on the role of media and imitation in the
formation of knowledge
• Plato posits a hierarchy of imitation and media
forms
– The Forms “First order things” Artistic
representations of things
• Plato devalues art and poetry for being at the
bottom of this hierarchy
– He values geometry and philosophy as having access
to the Forms
10. Plato
• As an allegory of media, the following identities
seem to hold
– Shadows = art and poetry
– Puppeteers = artists and poets
– Puppets = ? (part of the shadows’ apparatus)
• In contemporary terms, the shadows can be
identified with mass media
– TV, radio, film, social media, etc.
11. The allegory of the cave
lives on in Marxist critiques
of society. Reality is
production, and the
shadows are ideology and
religion.
But the philosopher Karl
Popper blames
totalitarianism on Plato’s
cave.
1967
12. Aristotle
• In the Poetics, Aristotle takes a less dim view
of art and poetry
– We learn through imitation; imitation is
fundamental to being human
– Different art forms convey different kinds of
meaning
• Tragedy (a form of drama) represents a
particular kind of human action
13. Note the preservation of the abstract over the visual
Aristotle’s reformulates Plato’s distinction
14. Where do digital media developers
fit into the allegory of the cave?
What kinds of imitation do we
produce?
15. Shadows = art and poetry = INTERFACE
Puppeteers = artists and poets = CODER
Puppets = = CODE
