card catalogue. Each section has the same form, but different contents. A sectional pattern may be set up as follows:
Economic and political aspects of Democracy
Here we have two sections, similar in form. Both are generalizations on the same level of abstraction. They are bound together in that both are social aspects of Democracy (if you agree with World and define "social" broadly as "dealing with the structure of society and the activity of its members"). "Social," so defined, is a generalization on a higher level of abstraction that includes economic and political Both economic and political are, therefore, in the same frame of reference.
When two or more sections are set up within one frame of reference and joined together by the conjunction and} we have a conjunctive sectional pattern. We call a sectional pattern such as Economic and political aspects of Democracy an open sectional pattern, because other sections may be added. Sections on the religious or the cultural aspects of Democracy may, for example, be included. When all possible aspects of Democracy find a place in the sectional pattern, we call it a closed sectional pattern. The pro and the con of chain stores would be a closed sectional pattern because it makes room for everything that can be said for or against chain stores.
The major parts of a conjunctive sectional pattern are joined together by the conjunction "and."
The major parts of a conjunctive sectional pattern are relatively independent of each other, but belong within the same frame of reference.
A conjunctive sectional pattern is open when more major parts may be added.
