575. Gnashing of teeth is the continual contention and combat of falsities with each other, consequently of those who are in falsities, joined with contempt of others, with enmity, mockery, ridicule, blaspheming; and these evils burst forth into lacerations of various kinds; since everyone fights for his own falsity and calls it truth. These contentions and combats are heard outside of these hells like the gnashings of teeth; and are also turned into gnashings of teeth when truths from heaven flow in among them. In these hells are all who have acknowledged nature and have denied the Divine. In the deeper of these hells are those that have confirmed themselves in such denials. As such are unable to receive any thing of light from heaven, and are thus unable to see any thing inwardly in themselves, they are for the most part corporeal sensual spirits, who believe nothing except what they see with their eyes and touch with their hands. Therefore all the fallacies of the senses are truths to them; and it is from these that they dispute. This is why their contentions are heard as gnashings of teeth; for in the spiritual world all falsities give a grating sound, and the teeth correspond to the outmost things in nature and to the outmost things in man, which are corporeal sensual.# (That there is gnashing of teeth in the hells may be seen in Matthew 8:12; 13:42, 50; 22:13; 24:51; 25:30; Luke 13:28.) # The correspondence of the teeth (n. 5565-5568). Those who are purely sensual and have scarcely anything of spiritual light correspond to the teeth (n. 5565). In the Word a tooth signifies the sensual, which is the outmost of the life of man (n. 9052, 9062). Gnashing of teeth in the other life comes from those who believe that nature is everything and the Divine nothing (n. 5568).
