Unit 2: Theory of Subjects

Notes
Example: Under Physics (fissioned primary basic subject), we have fundamentals,
properties of matter, sound, heat, radiation, electronics, electricity and magnetism (all secondary
basic subjects).

Under Geophysics (fused primary basic subject), we have subjects like volcanology, seismology
oceanology, etc. (all secondary basic subjects). We may recognize two varieties of secondary
basic subjects as below:
(a) Secondary basic subjects of Order 2.
(b) Compound secondary basic subjects.

2.4.8 Secondary Basic Subjects of Order 2

We have already seen that secondary basic subjects of ‘Order 1’ can be formed by the fission of
a primary basic subject. It is possible to achieve secondary basic subjects of ‘Order 2’ by dividing
‘Order 1’ further, by means of fission, if required.

Example: Atmospherology belongs to Order 1 and meteorology, agronomy, ionosphere
studies to Order 2.

2.4.9 Compound Secondary Basic Subjects

Attachment of speciator (that is, lamination of Kind 2) to a secondary basic subject leads to
compound secondary basic subjects: The following varieties of compound secondary basic subjects
are possible:

(a) Specials compound secondary basic subjects,
(b) Environmental compound secondary basic subjects,
(c) Systems secondary compound basic subjects.

Example: Physics, properties of matter and low temperature environment (here, physics
is a primary basic subject, properties of matter is a secondary basic subject derived by fission
from physics and low temperature environment is a speciator). Economics, consumption-capitalist
system (here economics is a basic subject, consumption is a secondary basic subject and capitalist
system is a speciator).

2.4.10 Compound Basic Subject by Lamination (Kind 2)

In order to achieve divisions of a primary basic subject, one can use a specific-explicit characteristic,
“The ideas derived on the basis of a characteristic are used to qualify or speciate the totality of
the subjects going with the primary basic subject concerned. Here, each of the ideas derived on
the basis of a characteristic is called a speciator. The attachment of a speciator to the primary
basic subject to be qualified is called compounding or lamination of Kind 2.” This leads to
primary basic subjects or compound basic subjects. A variety of compound basic subjects
recognized on the basis of variety of the speciators used in lamination are as follows:
(a) Specials compound basic subjects.
(b) Environmental compound basic subjects.
