I am going to put off explaining Table&nbsp;2, that presents a sample of what I call ''interpretive categories'' for higher order propositions, until after we get beyond the 1-dimensional case, since these lower dimensional cases tend to be a bit ''condensed'' or ''degenerate'' in their structures, and a lot of what is going on here will almost automatically become clearer as soon as we get even two logical variables into the mix.

As always, it is frequently convenient to omit a few of the finer markings of distinctions among isomorphic structures, so long as one is aware of their presence and knows when it is crucial to call upon them again.

The next higher order universe of discourse that is built on ''X''° is ''X''°2 = [''X''°] = <nowiki>[[</nowiki>''x'', ''y''<nowiki>]]</nowiki>, which may be developed in the following way.  The propositions of ''X''° become the points of ''X''°2, and the mappings of the type ''m'' : (''X'' &rarr; '''B''') &rarr; '''B''' become the propositions of ''X''°2.  In addition, it is convenient to equip the discussion with a selected set of higher order operators on propositions, all of which have the form ''w'' : ('''B'''² &rarr; '''B''')^''k'' &rarr; '''B'''.

The next higher order universe of discourse that is built on <math>X^\circ</math> is <math>X^{\circ 2} = [X^\circ] = [[x, y]],</math> which may be developed in the following way.  The propositions of <math>X^\circ</math> become the points of <math>X^{\circ 2},</math> and the mappings of the type <math>m : (X \to \mathbb{B}) \to \mathbb{B}</math> become the propositions of <math>X^{\circ 2}.</math> In addition, it is convenient to equip the discussion with a selected set of higher order operators on propositions, all of which have the form <math>w : (\mathbb{B}^2 \to \mathbb{B})^k \to \mathbb{B}.</math>

To save a few words in the remainder of this discussion, I will use the terms "measure" and "qualifier" to refer to all types of higher order propositions and operators.  To describe the present setting in picturesque terms, the propositions of [''x'', ''y''] may be regarded as a gallery of sixteen venn diagrams, while the measures ''m'' : (''X'' &rarr; '''B''') &rarr; '''B''' are analogous to a body of judges or a panel of critical viewers, each of whom evaluates each of the pictures as a whole and reports the ones that find favor or not.  In this way, each judge m_j partitions the gallery of pictures into two aesthetic portions, the pictures (''m''_''j'')^–1(1) that ''m''_''j'' likes and the pictures (''m''_''j'')^–1(0) that ''m''_''j'' dislikes.
