Lactantius

“ For to conjecture that you know that which you do not know, is not the part of a wise, but rather of a rash and foolish man. Therefore if nothing can be known, as Socrates taught, or ought to be conjectured, as Zeno taught, philosophy is entirely removed. Why should I say that it is not only overthrown by these two, who were the chiefs of philosophy, but by all, so that it now appears to have been long ago destroyed by its own arms? ”

“ Philosophy has been divided into many sects; and they all entertain various sentiments. In which do we place the truth? It certainly cannot be in all. Let us point out some one; it follows that all the others will be without wisdom. Let us pass through them separately; in the same manner, whatever we shall give to one we shall take away from the others. For each particular sect overturns all others, to confirm itself and its own doctrines: nor does it allow wisdom to any other, lest it should confess that it is itself foolish ”

“ Whatever sect you shall praise and pronounce true, that is censured by philosophers as false. Shall we therefore believe one which praises itself and its doctrine, or the many which blame the ignorance of each other? ”
