Let a sexual partner team (husband/wife or two lovers) re-enact their most recent quarrel. (If nobody will admit that they "quarrel," let the chosen subjects re-enact their most recent disagreement.)
Let this couple then reverse roles and let each one "play" the other in a continuation of the disagreement. Attempt to employ the technique of Method Acting: let each player try to feel the point of view of the other while acting the other.
See if you have two people in the group with opposed views on some "hot" issue (e.g., abortion, gun control, the war on drugs, etc.). Let them each attempt, by Method Acting, to present the point of view of the other, as sincerely as possible.
Let one member of the group acquire the following thirteen items:
a toy fire-truck;
a Barbie doll;
a reproduction of a Picasso painting,
a brick;
a screw-driver;
a hammer;
a turkey feather;
a piece of balsa wood;
a rubber ball;
a piece of hard wood, such as birch;
a "ghetto blaster" (portable stereo)
a pornographic novel;
a philosophical treatise by Bishop George Berkeley.
Place these items on the floor and let everybody sit around them. First, divide them into two groups — red things and not-red things. See how many times ambiguous cases arise (e.g., should a book with a red-and-white cover go in the red pile or the not-red pile?).
Let the 13 items be divided into another two groups — useful objects and toys. See how many ambiguities arise. (Does art belong among toys? Does pornography?)
Each week, as long as the group continues, let somebody think of another dualism and divide the 13 items into two piles according to that new dichotomy.
Note each case where two things which fall into different groups according to one dualist system fall into the same group according to another dualist system.
(E.g., balsa wood and hard wood will fall into the same group if one divides "wooden things" from "non-wooden things," but will fall into different groups if one divides "things that float" from "things that do no not float.")
Note how the Aristotelian argument "It 'is' either an A or a not-A” appears after you have found several things that belong on the same side of one[…]
