First of all, there is undoubtedly a Truth one and eternal which we are seeking, from which all other truth derives, by the light of which all other truth finds its right place, explanation and relation to the scheme of knowledge. But precisely for that reason it cannot be shut up in a single trenchant formula, it is not likely to be found in its entirety or in all its bearings in any single philosophy or scripture or uttered altogether and forever by any one teacher, thinker, prophet or Avatar.
Nor has it been wholly found by us if our view of it necessitates the intolerant exclusion of the truth underlying other systems; for when we reject passionately, we mean simply that we cannot appreciate and explain. Secondly, this Truth, though it is one and eternal, expresses itself in Time and through the mind of man; therefore every Scripture must necessarily contain two elements, one temporary, perishable, belonging to the ideas of the period and country in which it was produced, the other eternal and imperishable and applicable in all ages and countries.
Moreover, in the statement of the Truth the actual form given to it, the system and arrangement, the metaphysical and intellectual mould, the precise expression used must be largely subject to the mutations of Time and cease to have the same force; for the human intellect modifies itself always; continually dividing and putting together it is obliged to shift its divisions continually and to rearrange its syntheses; it is always leaving old expression and symbol for new or, if it uses the old, it so changes its connotation or at least its exact content and association that we can never be quite sure of understanding an ancient book of this kind precisely in the sense and spirit it bore to its contemporaries.
What is of entirely permanent value is that which besides being universal has been experienced, lived and seen with a higher than the intellectual vision. Only those Scriptures, religions, philosophies which can be thus constantly renewed, relived, their stuff of permanent truth constantly reshaped and developed in the inner thought and spiritual experience of a developing humanity, continue to be of living importance to mankind. The rest remain as monuments of the past, but have no actual force or vital impulse for the future.
