Example 1.  Prognostic Signs And Symptoms (concl.)

Under conditions like those of the present Example, where a preponderance
of the logical qualities come in exhaustive and mutually exclusive sets,
it is possible to improve the format of the model outputs in such a way
that they can be read as simple outline structures that organize sets
of models under the heads of their positive features alone.  This is
possible because there is such a degree of redundancy in the given
lexicon that a majority of the negative features have alternative
expressions in solely positive terms.

For instance, dichotomies after the pattern of {laughter, seriousness}
and {less_dangerous, more_dangerous} allow us to express "not laughter"
as "seriousness", "not seriousness" as "laughter", "not less_dangerous"
as "more_dangerous", and "not more_dangerous" as "less_dangerous", all
without loss of information.

Thus, we can pass from the outline of positive and negative features that
was previously associated with Node 5 to the outline of positive features
that we give as follows:

|   delirium                                                |
|    laughter                                               |
|     less_dangerous                                        |
|    seriousness                                            |
|     more_dangerous                                        |
|   laughter                                                |
|    less_dangerous                                         |
|    more_dangerous                                         |
|   seriousness                                             |
|    less_dangerous                                         |
|    more_dangerous                                         |
|                                                           |

In this case, the fact that "not delirium" has no positive expression in
the lexicon leads to a minor lack of expressiveness in the outline format,
but this could be remedied in the next draft of theory by placing the term
"delirium" in contrast with a newly added term, most typically, "normal".
