Bearing in mind that reality derives its intelligibility from its essential conformity with the Divine Mind, and that the human mind derives _its_ truth from the reality, we can understand how it has been said of truth in general that it is first in the Uncreated Intellect, then in things, then in created intellects; that the primary source and measure of all truth is the Divine Intellect Itself Unmeasured, “mensurans, non mensuratus”; that created reality is measured by, or conformed with, the Divine Intellect, and is in turn the measure of the human intellect, conforming the latter with itself, “mensurans et mensurata”; and that, finally, the human intellect, measured by created reality and the Divine Mind, is itself the measure of no natural things but only of the products of human art, “intellectus noster ... non mensurans quidem res naturales, sed artificiales tantum”.(167) Is truth _one_, then, or is it _manifold_? Logical truth is manifold—multiplied by the number of created intelligences, and by the number of distinct cognitions in each. The primary ontological truth which consists in the conformity of all reality with the Divine Intellect is one: there is no real plurality of archetype ideas in the Divine Mind; they are manifold only to our imperfect human mode of thinking. The secondary ontological truth which consists in the conformity of things with the abstract concepts of created intelligences is conditioned by, and multiplied with, the manifoldness of the latter.(168) Again to the question: Is truth _eternal_ or _temporal_?—we reply in a similar way that the truth of the Divine comprehension of reality, actual and possible, is eternal, but that no other truth is eternal. There is no eternal truth outside of God. Created things are not eternal; and truth is consecutive on reality: where there is no reality there is no ontological truth: the conformity of things with human conceptions and the logical truth of the latter are both alike temporal.(169)
