23. There is one human God who is the source of everything. All the elements of human reason unite in, and in a sense center on, the fact that a single God is the Creator of the universe. As a result, rational people, on the basis of their shared understanding, neither do nor can think in any other way. Tell people of sound reason that there are two creators of the universe and you will feel within yourself how they recoil from this notion, perhaps simply from the tone of their voice in your ear. This enables us to see that all the elements of human reason unite and center on the oneness of God.

There are two reasons for this. The first is that in its own right, our very ability to think rationally is not our own property. It is a property of God within us. Human rationality in general depends on this fact, and this general property causes our reason more or less spontaneously to see the oneness of God. The second is that through our rational ability either we are in heaven's light or we draw from it some general quality of its thought, and the all-pervading element of heaven's light is that God is one.

This is not the case if we have used our rational ability to skew our lower understanding. In this case we still possess the ability, but by the distortion of our lower abilities we have steered it off course, and our rationality is not sound.

The reason why 'death' means damnation is that with those who have been damned the truths of faith and forms of the good of charity have been wiped out. These are what constitute the most real kind of life a person has, for they are received from the Lord, who is the one and only source of life. When they have been wiped out their place is then taken by falsities and evils; and these, being the opposites of truths and forms of good which are the constituents of life, are therefore the constituents of death - spiritual death, which is damnation, hell, and eternal unhappiness. The reason why those immersed in evils and falsities, that is, those who are in hell, continue to be alive is that they were born human beings and consequently have the ability to receive life from the Lord. And they do receive life from the Lord, as much life as will enable them to think, reason, and speak, to make their evil look like good and their falsity like truth, and so to give the appearance of life.
