2.  A phase relation is the assembling together
of two or more of
(a) Subjects [Basic or Compound]
(b) Isolate ideas.
Assembling is done to express one or the other
of possible relations between the components
of the assembly.
Each component in the assembly, in its turn, is
called a “phase”. They are called “phase 1” and
“phase 2” as determined by their sequence in
the assemblage.

3.  A subject is One Phased if it consists of only
a single (MC) or any of its substances i.e., if
it is a (BC) or a (CdC).
 A subject is Two Phased if it brings into
relation two (BC) or two (CdC) or a (BC) and
a (CdC).
 The class formed by a Two Phased subject is
called a complex class (CxC).
 The constituent of a Two phased subject
which is the primary subject of exposition or
is otherwise deemed to be primary is called
the First Phase.

4.  The constituent of a Two Phased specific
subject which is merely affecting the
exposition of the first phase, is called its
Second Phase.
 The class number of a Two Phased specific
subject is got by inserting, between the class
numbers of the first and the second phases,
the connecting symbol 0 and an appropriate
digit to represent the phase relation.

5. Phase, Intra-Facet and Intra-Array
Relation
Intra-Array Intra-Facet Phase or Inter
Subject
Nature of
Relation
t j a General
u k b Bias
v m c Comparison
w n d Difference
y r g Influencing
Each phase-relation digit is a roman small.

6. General Relation Phase
 “General Relation” denotes a more or less all-
comprehensive relation that is, not merely
any one of the other relations listed in the
schedule.
 The constituent, whose class number is of
smaller ordinal value than that of the order,
is to be used as the First Phase.
 The Second Phase is called relation phase in
this case.
 Example: W0aX
Relation between political science and economics.

7. Bias Phase
 Bias Phase Relation indicates that the
exposition of the First Phase is biased
towards the Second Phase, that is exposition
is specially attuned either by selection or
arrangement of topics or emphasis or
standard or examples or other means to the
need of a specialist in the subject forming the
Second Phase.
 The Second Phase is called Bias Phase in this
case.
 Example: L0bZ
Medical Jurisprudence

8. Comparison Phase
 When a comparison is made between two
subjects, the one whose class number is the
earlier ordinal number is to be treated as the
First Phase.
 The Second Phase is called comparison phase
in this case.
 Example: (a) C0cE
Physics compared to chemistry.
(b) D30m5
Comparison of building engineering and
transport.

9. Difference Phase
 When the difference between two subjects is
exposition, the one whose class number is
the earlier ordinal number is to be treated as
the First Phase.
 The Second Phase is called the Difference
Phase in this case.
 Example: B850dCN2
Difference between wave function and wave
mechanics.

10. Influencing Phase
 When the influencing of one subject on
another subject is expounded, the latter
should be treated as the First Phase.
 The second phase is called Influencing Phase
in this case.
 Example: (a)W0gU
Political science Influenced by geography.
(b) S:5230y21
Influence of feeling of laughter on joy.

11. Inter-Facet Relation
 It is possible to have books expounding the
relation between two isolates in one and the
same facet of a class.
 We shall call it Intra-Facet Relations (IFR).
 An isolate thus formed by bringing into
relation two isolates in the same facet shall
be called a Complex Isolate (CxI).
 A (CxI) belongs to the same facet as its
constituents.
 Intra-Facet relation is different from mutual
denudation or super- imposition.

12. Intra-Array Relation
 It is possible to have books expounding the
relation of two Array-Isolates in one and the
same array.
 An Array Isolate formed by thus bringing into
relation two array isolates in the same array
may be called a Complex Array Isolate.
 Examples: (a) X:5.440j56
Commercial relation between India and Great
Britain.
(b) Z,40j5
Relation between tools and crime.
