The number "two" has two different meanings in the Bible. In most cases "two" indicates a joining together or unification. This is easy to see if we consider the conflicts we tend to have between our "hearts" and our "heads" -- between what we want and what we know. Our "hearts" tell us that we want pie with ice cream for dinner; our "heads" tell us we should have grilled chicken and salad. If we can bring those two together and actually want what's good for us, we'll be pretty happy. We're built that way -- with our emotions balanced against our intellect -- because the Lord is built that way. His essence is love itself, or Divine Love, the source of all caring, emotion and energy. It is expressed as Divine Wisdom, which gives form to that love and puts it to work, and is the source of all knowledge and reasoning. In His case the two aspects are always in conjunction, always in harmony. It's easy also to see how that duality is reflected throughout creation: plants and animals, food and drink, silver and gold. Most importantly, it's reflected in the two genders, with women representing love and men representing wisdom. That's the underlying reason why conjunction in marriage is such a holy thing. So when "two" is used in the Bible to indicate some sort of pairing or unity, it means a joining together. In rare cases, however, "two" is used more purely as a number. In these cases it stands for a profane or unholy state that comes before a holy one. This is because "three" represents a state of holiness and completion (Jesus, for instance, rose from the tomb on the third day), and "two" represents the state just before it.

133. After this they took up the second topic for discussion, why man does not come by birth into the knowledge necessary to any love, whereas both higher and lower animals and birds come by birth into the kinds of knowledge necessary to all their loves.

First they confirmed the truth of the proposed question by various considerations. With respect to man, for example, they observed that the human being does not come by birth into any knowledge, not even into knowledge relating to conjugial love.

They inquired as well and learned from investigators that an infant does not even possess the instinctive knowledge to be able to go to its mother's breast, but it must be placed in contact with it by the mother or nurse. It only knows how to suckle, and it got this from a continual sucking in the womb. The infant afterwards also does not know how to walk, the investigators said, nor how to articulate sound to form a single human word. Indeed, it does not even know how to voice the affection of its love as animals do. Moreover, it does not know any source of food that is good for it, either, as all animals do, but clutches at whatever it comes upon, whether it is clean or unclean, and puts it into its mouth.

Without being taught, the investigators said, the human being does not even know enough to distinguish the opposite sex, and nothing at all about how to make love to one. Even young men and women do not know how to make love without learning about it from others, even if they have been educated in the various arts and sciences.

In a word, the human being is born flesh, like a worm, and remains flesh unless he learns to acquire knowledge, intelligence and wisdom from others.

[2] Next, with respect to animals, such as beasts of the earth, birds of the sky, creeping things, fish, and little creatures called insects, the people confirmed that both higher and lower animals come by birth into all the kinds of knowledge necessary to their life's loves. They come, for example, into knowledge of all things having to do with their proper diet, with their place of habitation, with their mating and reproduction, and with the rearing of their young.

The people confirmed these observations with marvelous illustrations that they recalled to memory from things they had seen, heard or read about in the natural world (as they termed our world in which they had formerly lived), where animals are not representational but real.

After they had thus verified the truth of the proposed question, the people turned their attention to investigating and finding the ends and causes by which to explain and uncover the answer to this mystery. And they all said that this state of affairs must result from Divine wisdom, that a human being may be a human being, and an animal an animal; and that therefore man's imperfection from birth becomes his perfection, while an animal's perfection from birth is its imperfection.
