What critique can the skeptic give to the pure?
What does the truth-seeker have to offer to the pure-hearted? How could a holder of truth bear to correct a pure-hearted, radiant individual?
If the truth-seeker thirsts after knowledge, but not goodness, the pure-hearted reigns over her, because his knowledge profits neither her nor anyone around her.
If the pure-hearted seeks goodness, but not knowledge, he is ignorant. But his goodness causes him to lean on others, bless others with his presence, and by nature of his goodness is a teacher to others through his way of life. He still reigns over the truth-seeker, because he naturally professes Christ through his life.
In this way, we see that stupidity as we commonly understand it is no tragedy whatsoever. Blessed are the pure of heart, for they shall see God.
But who would say that truth and goodness are dichotomous? Who would not marvel at the two if they came together? Both are obviously very good and work together; they're perhaps even equal in value. But one is first among equals. One is primary.
