Definition: Concordance is what makes goodness, greatness etc. agree in unity and plurality.
Division and Clarification: Like difference, concordance is divided into sensual and sensual etc. Thus, concordance is a principle that makes the differentiator and differentiable agree with bonified being that is good, great etc. and makes the bonifier agree with differentiated being that is bonified, magnified etc. And likewise with the other principles.
Without concordance, the initial virtue of goodness would have no repose, as without concordance there would be no end, beginning or saffron triangle, and the privation of concordance in good, great etc. being would naturally cause contrariety contradicting the end. Beings would exist through contrariety, while concordance would annihilate them, which is impossible, and thus concordance must be a necessary principle. Abstract concordance is a common principle concretely comprising many concordant things. Hence, to give the artist knowledge of supreme and lesser concordance, supreme concordance is considered as the cause and lesser concordance as its effect.
Concordance is a principle of this Art meant for discovering the conditions of supreme concordance as follows: now supremely concordant being agrees in one good, great etc. being with no contrariety among its concordable parts. No other concordance can surpass supreme concordance in supreme goodness, greatness, eternity etc. because supreme concordance would then be external to its own essence and to the essence of goodness etc., which is impossible. Thus, with the knowledge of supreme concordance we can discover the conditions of lesser concordance, as effects are known by their cause.
Nature: The fullness and nature of concordance exists in the concorder, concordable and concording necessarily giving rise to concorded being.
The above plainly shows that concordance is a necessary principle of this Art.
