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.)
