Lactantius,
Ante-Nicene Fathers Vol. VII, The Divine Institutes…
(1885)
“ For he cannot in any other way reject the things which are false, or choose and approve of those which are true; but if even by chance he should effect this, he would most surely act the part of the philosopher; and though he could not defend those things by divine testimonies, yet the truth would explain itself by its own light. Wherefore the error of those is incredible, who, when they have approved of any sect, and have devoted themselves to it, condemn all others as false and vain, and arm themselves for battle, neither knowing what they ought to defend nor what to refute ”
