38. Verse 18 And to have dominion over the day and the night, and to make a distinction between the light and the darkness; and God saw that it was good.

'The day' is used to mean good, and 'the night' evil. Consequently goods are called 'the works of the day', whereas evils are called 'the works of the night'. 'The light' is used to mean truth, and 'the darkness' falsity, just as the Lord says,

Men preferred darkness rather than light; he who does the truth comes to the light. John 3:19-21.

Verse 19 And there was evening, and there was morning, a fourth day.

203. We say that offspring derive from their parents a conjugial connection between good and truth, because from creation a union of these two has been introduced into the soul of everyone; for this is the ingredient which flows into a human being from the Lord and causes his life to be human. However, this conjugial union passes from the soul into subsequent elements until it reaches the final constituents of the body, and as it passes, on one level or another it is changed by the person himself in many ways, and sometimes into the opposite, which we call the conjugal or connubial connection between evil and falsity. When this occurs, the mind is closed up from below, and sometimes is twisted around like a spiral coil into the opposite direction.

Nevertheless, in some people the union is not closed up but remains partly open above, and in some cases all the way open. In either circumstance, this conjugial union is something from which offspring derive inclinations from their parents, a son in one way and a daughter in another. The conjugial union has this effect, because conjugial love is the fundamental love of all loves (as we showed above in no. 65).
