On the Creation of Magistrates (1.61-1.65)

for all these men are but guessers at what is probable and likely, at different times adopting different notions from the same appearances, because the subjects of their art have no stable and constant character, and because the intellect has never devised any accurate test by which those opinions which are approved may be examined.

And all these things are but the furniture of impiety. How so? Because he who attends to them, and who allows himself to be influenced by them, disregards the cause of all things, looking upon those things alone as the causes of all things, whether good or evil; and he does not perceive that he is making all the cares of life to depend upon the most unstable supports, upon the motion of birds and feathers in the air, in this and that direction; and upon the paths of reptiles, crawling along the ground, which creep forth out of their holes in quest of food; and even upon entrails, and blood, and dead corpses, which, the moment that they are deprived of life, fall to pieces and become confused; and being deprived of their original nature which belonged to them, are changed, and subjected to a transformation for the worse.
