Induction and Science

Gday Well, here is the reference from Juvenal :'Rara avis in terris nigroque simillima cycno. '
"A bird rarely seen on earth, and very like a black swan."
Satires 6, 165(Juvenal chose a black swan for his comparison because the Romans had no idea that black swans even existed and so it was considered as impossible as a white crow.)From :

Gday again,Augustine also makes a reference to a black swan (as something that does not exist, like a bird with 4 feet.)"For who ever saw a black swan? And therefore no one remembers a black swan; yet who is there that cannot conceive it? For it is easy to apply to that shape which we have come to know by seeing it, a black color, which we have not the less seen in other bodies; and because we have seen both, we remember both. Neither do I remember a bird with four feet, because I never saw one; but I contemplate such a phantasy very easily, by adding to some winged shape such as I have seen, two other feet, such as I have likewise seen."On the Trinity, Book XI, Chap 10K.
