1388. The second kind of perception, as has been said, is what is common to all, in the highest perfection to angels, and to spirits according to their quality. It consists in knowing the quality of another at his first approach, even if he does not speak. He manifests himself forthwith by a certain wonderful influx. It is known of a good spirit, not only of what goodness he is, but also of what faith; and when he speaks, this is known from every word. Of an evil spirit it is known of what evil he is and of what unbelief; and when he speaks, this is known from every word, and so manifestly that there can be no mistake. Something similar appears with men, who likewise can sometimes know from another's gesture, looks, or speech, what he is thinking, even although it is contrary to what he says; and this knowledge is natural to man, deriving its origin and character from the nature of spirits, and thus from the spirit of the man himself, and its communication with the world of spirits. This communicative perception has its beginning in the fact that the Lord wills that all goods may be communicable, and that all may be affected by mutual love, and so be happy. Hence such a perception reigns universally also among spirits.
