566 INTELLECTUAL SYMBOLISM. 
by their nature placed in relation to our finite intelligence,—all things that are included 
in the field of objective human philosophy. Whether cognition is possible under other 
relations, by beings differently constituted from ourselves, we have no means of determi- 
ning; we may, however, safely assert, that there are no relations inconsistent with those 
that have been pointed out, and that there can be nothing real or possible, which some 
necessity does not underlie, and which is not dependent on that necessity for its existence. 
426. In Principle, Essence, and Idea (the subjective-objective, objective-objective, and 
objective-subjective), the answers must be sought to the three great philosophical ques- 
tions, How ?—What?’—Why? That which is logically first, is chronologically last, so 
that though the objective order of creation and dependence may commence with Principle, 
the subjective order of investigation would proceed from Idea, through Essence, to Princi- 
ple. Principle and Idea are used synonymously by many writers, but as they are made 
to include existence under both subjective-objective and objective-subjective relations, it 
is desirable that the difference of relations should be indicated by different names. 
427. If we adopt as objective symbols, P for Principle, E for Essence, and I for Idea, 
the subdivisions of the next lower plane may be thus represented : 
PP, Capacity. EP, Form. IP, Quantity. 
PE, Subsistence. HH, Substance. TE, Quality. 
PI, Predication. KI, Condition. II, Modality. 
428. The relations that are represented by the symbols, are unchangeable, but the 
names are merely proposed for consideration. If a careful study of the several relations, 
and a precise determination of their boundaries, shall lead to the suggestion of more fit- 
ting terms, they can readily be adopted. ‘The same remarks may be made with regard to 
the following schedule of the third order of subdivisions : 
PPP, Mutability. PPH, Tendency. PPI, Consequence. 
PHP, Ordination. PHE, Efficiency. PEI, Dependence. 
PIP, Accident. PIE, Species. PII, Genus. 
EPP, Space. EPH, Time. EPI, Position. 
KEP, Matter. HEE, Mind. EEL, Force. 
EIP, Phenomenon. KIH, Relation. II, Law. 
IPP, Unity. IPE, Plurality. IPI, Totality. 
IEP, Negation. IEE, Limitation. JEL, Affirmation. 
IIP, Necessity. IIH, Reality. III, Possibility. 
429. The following classification, in accordance with symbolic resemblances, will per- 
haps render the meaning of the several terms clearer and more definite. 
1. Class of pure Principle. 
PPP, Mutability.
