Origen

“ For the present, however, let it be granted that an art of divination does exist, in order that I may in this way show to those who are prejudiced on the subject, that if this be admitted, the superiority of man over irrational animals, even over those that are endowed with power of divination, is great, and beyond all reach of comparison with the latter. ”

“ Let the principal point of investigation, however, be this: whether there actually is or not an art of divination, by means of birds and other living things believed to have such power. For the arguments which tend to establish either view are not to be despised. On the one hand, it is pressed upon us not to admit such an art, lest the rational being should abandon the divine oracles, and betake himself to birds; and on the other, there is the energetic testimony of many, that numerous individuals have been saved from the greatest dangers by putting their trust in divination by birds. ”

“ And especially, were eagles aware beforehand of the designs formed against their young, either by serpents crawling up to their nests and destroying them, or by men who take them for their amusement, or for any other useful purpose or service, they would not have placed their young in a spot where they were to be attacked; and, in general, not one of these animals would have been captured by men, because they were more divine and intelligent than they. ”
