In his work, though entitling chapters as evils beings, Agrippa also mixes in angels and other beings, he makes not a clear distinction among them. He as usual almost does not state directly a position on the subject of origin and features of ethereal beings but offers quotations, third assertions and some own:

Evil spirits, comments Agrippa, do wander up and down in this inferior world. Some enraged against all, are called devils, but what they are and how they are, is not clear. May be are apostate angels. Ancient Greece thinks not that all these are damned, nor that they are all by design evil, but that from the creation of the world, the apportionment of things is commanded by this means, that the tormenting of sinful souls is made over to them.

Others say that not any devil was created evil, but that they were driven and expelled of heaven, from the orders of good angels for their pride. Others describe this fall due to a rebelling army. Some say that the devils themselves confess their fall of being cast into Earth; that are close to humans, wander up and down in dark air inhabiting lakes, rivers, seas and earth; that conquer those who dig wells and metals; cause the breach of the earth, strike the foundation of mountains, and exasperate not only men, but also other creatures. Some devils feel great joy in wars and effusion of blood. Some evil beings satisfy with illusion and laughing; devise by preference against tired men then hurt them. Some change themselves into big or small forms for tormenting men with fear.

There are nocturnal, diurnal, meridional devils and them have varied names. They are spirits who act of their own free will, left the service of God with their evil prince.

If they began to repent a little, they incarnate as humans. That further by this repentance, after the resurrection, by the same ways by the which they came into the flesh, they might at the last come back to God, being then also freed from ethereal and aerial bodies. There are many of the fallen angels who hope for their salvation. Some repentant devils shall be forgiven.^[167]
