417. "From the things visible in nature, every one can confirm himself in favor of the Divine if he will. Moreover, he Who thinks of God from life does so confirm himself; as, for example, When he sees the birds of the air, that each species knows its foods and where they are, recognizes its kind by sound and sight, and among other kinds, Which are its friends and which its enemies; that they choose their mates, know how to love, skillfully build nests, there lay their eggs, sit upon them, know the time of incubation, and when this is passed, hatch out their young, love them with the utmost tenderness, gather them under their wings, bring food in their bills and feed them until they come to their own right and can themselves do the same things and Procreate a family to perpetuate the species. Every one who is willing to think of the Divine influx through the spiritual world into the natural, can see it in these operations. Moreover, if he will, he can say in his heart, Such knowledge cannot flow into these birds from the sun through its rays of light; for the sun from which nature draws her origin and essence is pure fire; and therefore the rays of its light are absolutely dead. Thus he can conclude that such things are from the influx of Divine Wisdom into the ultimates of nature.
