The beasts have no ignorance of anything, that concerns them; but have all the sensible, intuitive knowledge of everything that is the good of their nature. But man left to his reason is all over ignorance, doubt, conjecture, and perlexity in matters of the highest moment, about what he himself is, what is his chief good, where he is to seek it, and how to obtain it. For to ask your reason, how God is your God, how you are in him, and from him, what he is in himself, and what he is in you, is but like asking your hands to feel out the thickness, or the thinness, of the light. To ask your reason, whether the soul of man is immortal in its nature, is to as good purpose, is going no father out of the way, than if you was to ask your eyes to show you, where extension begins, and where it ends. To ask your reason, whether man has anything of God, or the divine nature in him, is just as suitable to the nature and power of your reason, as if you was to ask your nose, whether this or that sweet, aromatic smell in the garden, has any heavenly power mixed with, and opening itself in it.
