What speech is in each person, literature is in society. By it one can know what a society is like.
“With their tongues they practiced deceit.” This was said in general about the tongue of the passionate. Now he turns to listing the forms of the tongue’s depravity.
The first is flattery. “They practiced deceit” is edolousan. Dolos means malicious craftiness.
The malicious craftiness of the tongue is the skill of covering evil aims with good speech. Through this one leads another into deception and harm for the sake of one’s own gain.
This is a direct consequence of egoism. Whether egoism meets egoism, or egoism meets goodness, egoism cannot act without flattery.
In the first case, it would otherwise provoke another’s egoism and stir up opposition against itself. In the second, by exposing itself, it would reveal what goodness abhors.
Passionate egoism is therefore forced to scheme, covering itself with flattery.
“The poison of asps is under their lips.” Under their lips means under their words, or in their words. The poison of asps signifies harmfulness and destruction.
Only listen to what they say, and you will suffer evil. The same will happen to you as to one who has taken the poison of an asp.
This signifies the highest degree of what is meant by the saying, “With their tongues they practiced deceit.”
When they flatter with the tongue, they merely lead one toward evil. They entangle one in certain deeds and undertakings that bring harm to others and profit to themselves.
But when the poison of asps is in their words, evil enters the soul together with those words.
Here one may understand blasphemers of the ways of God and spreaders of evil teachings. Covering falsehood with attractive plausibility, they introduce it into the soul.
Having driven truth out of the soul, they poison it with this falsehood.
