The chart got distorted so here's a second try.
It's a series of oppositions. I have marked the EPIC qualities with *.
DRAMATIC THEATER * EPIC THEATER
plot * narrative
implicates spectator into drama
*makes spectator an observer
wears down his capacity for action
* arouses his capacity for action
provides him with sensations
*forces him to make decisions
provides experience
* provides a picture of the world
involves the spectator *confronts the spectator
suggestion *argument
feelings are preserved
*feelings are propelled into perceptions
man is assumed known *man is the object of inquiry
man unalterable * man alterable and altering
suspense about the outcome
* suspense about the progress
each scene exists for another
* each scene for itself
linear development * in curves
evolutionary determinism *evolutionary leaps
the world, as it is * the world, as it becomes
what man ought to do
*what man is forced to do
man as a fixed point * man as a process
his instincts * his motivations
thought determines being
*social being determines thought
(Brecht did not intend, obviously, that epic theater be absolutely one
way and not at all the other way; it is a question more of tendency.)
