2. But since created things are various and numerous, they are indeed well fitted and adapted to the whole creation; yet, when viewed individually, are mutually opposite and inharmonious, just as the sound of the lyre, which consists of many and opposite notes, gives rise to one unbroken melody, through means of the interval which separates each one from the others. The lover of truth therefore ought not to be deceived by the interval between each note, nor should he imagine that one was due to one artist and author, and another to another, nor that one person fitted the treble, another the bass, and yet another the tenor strings; but he should hold that one and the same person [formed the whole], so as to prove the judgment, goodness, and skill exhibited in the whole work and [specimen of] wisdom. Those, too, who listen to the melody, ought to praise and extol the artist, to admire the tension of some notes, to attend to the softness of others, to catch the sound of others between both these extremes, and to consider the special character of others, so as to inquire at what each one aims, and what is the cause of their variety, never failing to apply our rule, neither giving up the [one] artist, nor casting off faith in the one God who formed all things, nor blaspheming our Creator.
