Descriptive truth, which consists in the agreement of the mind with reality, requires affirmation of the existence of an independent reality. The modern error of ontological idealism must be corrected.
Prescriptive truth consists in the agreement of the mind with right desire.
In addition to the tests of truth that depend on the agreement of the mind with reality or right desire, there is the test of coherence. If the human mind is confronted with an incompatibility between its prior judgments and a new judgment, it must seek intrinsic coherence or compatibility by choosing between its earlier judgments and the new one. In short, the mind must choose between its earlier hypotheses and a new hypothesis that calls for consideration. The test of coherence is governed by the principle of incompatibility. There is one further consideration, and that is the distinction between matters of truth and matters of tastes.
