In that region they are conjoined and conjointly look down upon the old or natural will and understanding, and so arrange all things therein as to moderate them. Who cannot see that if there were but one region in the human mind, and if both evils and goods and truths and falsities were there brought together and mixed together, there would be a conflict such as would arise if wolves and lambs, tigers and calves, hawks and doves, were brought together into one enclosure? What would result but a cruel slaughter, the savage beasts tearing in pieces the tame ones? This is why it has been provided that goods with their truths should be collected together in the higher region, so that they may subsist in safety, and resist assault, and also by constraints and other means may subjugate and afterward disperse evils with their falsities. This, then, is the same as was said in the preceding section, that in the regenerated man the Lord through heaven rules what pertains to the world. And the higher or spiritual region of the human mind is a heaven in miniature, while the lower or natural region is a world in miniature, and for this reason man was called by the ancients a microcosm [a little world], and he may also be called a microuranos [a little heaven].
