Transformation Found Poem (by Marvin Harris, in THE NATURE OF CULTURAL THINGS: Random House, 1964, p. 54)

The aim of our analysis
is to progress
from the idio-episode
to the episode level.
An episode exists
only when a particular idio-episode
is found in some sense to be similar
to another idio-episode.
To achieve this result,
each of the absolute stage coordinates
must be transformed into examples
of classes of entities or relations.

Thus,
the actor must be identified
as an example of a class of actors;
the object must be indentified
as a member of a class of objects;
the time must be identified
as a type of moment
rather than a nonrecurrent calendrical instant;
and the place must be described
as a kind of locality
rather than as a unique point
on the terrestrial grid.
