In reading this author [Montaigne] and comparing him with Epictetus, I have found that they are assuredly the two greatest defenders of the two most celebrated sects of the world, and the only ones conformable to reason, since we can only follow one of these two roads, namely: either that there is a God, and then we place in him the sovereign good; or that he is uncertain, and that then the true good is also uncertain, since he is incapable of it.
