It should be known, that the more perfect the angels are, the more perfectly are they able to think; for [thought], with those who are in beauty, that is, in excellence, beyond others, is harmonious. These are able to think more wisely than the rest, who are in a lower degree. This, the latter are not at all able to do, because the angels speak from their own good, and their own truth; for they are these things. Thus, those who are in a lower degree can by no means [think] like those who are in a higher. Hence it is, that the evil can not at all understand what celestial and spiritual good is, nor that truth is truth.
