Tertullian

“ By what means can the pupil-souls have resorted to their teachers, when they are parted from each other by so distant an interval? What profit, too, can any instruction afford them at all in their posthumous state, when they are on the brink of perdition by the universal fire? All other souls they thrust down to Hades, which Plato, in his Phædo, [2] describes as the bosom of the earth, where all the filth of the world accumulates, settles, and exhales, and where every separate draught of air only renders denser still the impurities of the seething mass. ”

“ Almost all the philosophers, who hold the soul’s immortality, notwithstanding their special views on the subject, still claim for it this (eternal condition) , as Pythagoras, and Empedocles, and Plato, and as they who indulge it with some delay from the time of its quitting the flesh to the conflagration of all things, and as the Stoics, who place only their own souls, that is, the souls of the wise, in the mansions above. ”
