We know, in a general sense, what “false” means. It’s the wrong answer on a “true or false” test; it’s saying 2+2=5; it’s saying that the sky is green and the clouds are orange.

That simplicity, however, comes from applying the idea of “truth” to simple, concrete facts. It gets much trickier when we try to apply the idea to the things we love and feel.

Consider, for instance, the idea that “you’ve got to look out for yourself, because no one else is going to.” Is that true? It feels true in a way, and seems to apply to a lot of real-world situations. To some degree, no matter how high-minded we might be, we have to take care of ourselves if we’re going to be any good to anyone else. But if we take that idea and make it central to our lives, will it help us be loving people? Or will it encourage selfishness, which is pretty strong in most of us anyway? Clearly the answer is the latter.

Swedenborg would label that a “falsity,” because it is ultimately a description of how to be selfish. “Love your neighbor as you love yourself” would, by contrast, be labeled a “truth” because it is a description of how to be caring and kind. Basically, statements describing or springing from love of the Lord and love of the neighbor are “truth” and those springing from love of self or love of worldly things are “falsity.”

You might wonder why that is. The fact that “look out for yourself” is selfish doesn’t make it necessarily untrue; it’s a selfish world! But in Swedenborg’s theology, the universe and reality itself are direct products of the Lord’s infinite love, and are thus ultimately expressions of love. The only reason selfishness exists is that the Lord created us with freedom, which includes the ability we have to reject His love and turn it toward ourselves instead. The Lord’s every intention and purpose is to get us turn away from ourselves and toward Him; if we do that, reality can fulfill its loving purpose.

True reality, then, is completely loving, and expressions that reflect and support that loving nature are “true” - they are aligned with reality in its purest, greatest and intended form. Statements that reject and deny that loving nature are “false” because they are contrary to reality’s true form.

But there’s an argument: Couldn’t someone use the idea that “you’ve got to look out for yourself, because no one else is going to” to become strong and self-reliant, in a better position to help others, and use it to be a better person? Yes, they could; ideas that are essentially false can at times be used for good purposes. In a broad application, religious systems can have false ideas about the Lord, but still lead people to good lives and ultimately to heaven. On the flip side, ideas that are essentially true can be used for evil purposes (“love thy neighbor” could prompt giving aid to someone engaged in evil, for instance). “Truth” only becomes truly real when it is married to the desire for good; “falsity” only becomes truly real when it is married to the desire for evil.

8265. 'The horse and its rider He has thrown into the sea' means in that as a result simply of His presence falsities arising from evil have been damned and cast into hell. This is clear from the meaning of 'the horse' as falsities belonging to a perverted understanding, for 'horse' means the power of understanding, see 2761, 2762, 3217, 5321, and in the contrary sense a perverted understanding, which is no understanding at all, and therefore falsity is meant in that contrary sense by 'horse' and false factual knowledge by 'Pharaoh's horse', 6125, 8146, 8148; from the meaning of 'rider' (or 'horseman') as reasonings based on that false knowledge, dealt with in 8146, 8148; and from the meaning of 'throwing into the sea' as damning and casting into hell. 'The sea', the Sea Suph at this point, is the hell where the falsities arising from evil are, the falsities of those belonging to the Church who have upheld separated faith and led a life of evil, see 8099, 8137, 8148, which is why they are called falsities arising from evil. The fact that those falsities were damned and cast into hell as a result simply of the Lord's presence was shown in the previous chapter. The evil cannot at all bear or put up with God's presence. His presence causes them pain, torments them, and so to speak snuffs the life out of them; they behave like those in the throes of death. The reason for this is that what is God's has the totality of power within it; it destroys and wipes out that which is opposed to it, namely falsity and evil. This is why at God's presence the life of those steeped in falsity and evil becomes burdensome and contains, in the measure that He is present, the feeling of hell within it. But in order that those steeped in falsities and evils may not be completely crushed and suffer torment they are shielded by their own falsities and evils, which act like mists. These are by nature such that they diminish, or divert, or smother the flow of what is Divine in the same way that earthly mists or clouds normally do to sunrays.

[2] These things are meant by the following words in John,

They will say to the mountains and rocks, Rush down on us and hide us from the face of Him who is seated on the throne and from the anger of the Lamb. For the great day of His anger has come; who therefore will be able to stand firm? Revelation 6:16-17.

Evils and falsities are meant by 'the mountains and rocks' which they will address, saying that they should rush down on them and hide them. 'The anger of the Lamb' means torment, the appearance being that the Divine would cause the torment because of His anger, but the reality being that the falsities and evils themselves are responsible for it. The words contained in Isaiah 2:10, Hosea 10:8, and Luke 23:30 have a similar meaning. The fact that damnation takes place as a result simply of the Lord's presence is also meant by these words that follow in the song,

You send out Your wrath, it eats them up like stubble. And with the wind of Your nostrils the waters were heaped up, the floods stood as a heap. You blew with Your wind, the sea covered them over; they sought a deep place. You stretched out Your right hand, the earth swallowed them. Verses 7-8, 10, 12.

Words with a similar meaning occur in very many other places in the Word.
