7.6.9   Upon hearing and believing these things, told by one of such credibility, all that my resistance gave way; and first I endeavoured to reclaim Firminus himself from that curiosity, by telling him that upon inspecting his constellations, I ought if I were to predict truly, to have seen in them parents eminent among their neighbours, a noble family in its own city, high birth, good education, liberal learning. But if that servant had consulted me upon the same constellations, since they were his also, I ought again (to tell him too truly) to see in them a lineage the most abject, a slavish condition, and every thing else utterly at variance with the former. Whence then, if I spake the truth, I should, from the same constellations, speak diversely, or if I spake the same, speak falsely: thence it followed most certainly that whatever, upon consideration of the constellations, was spoken truly, was spoken not out of art, but chance; and whatever spoken falsely, was not out of ignorance in the art, but the failure of the chance.
