These feelings were known to the ancients also, who gave to this very conviction the form suggested by their religion. Pericles[1] in his funeral eulogy of the warriors who fell at the siege of Samos declared that they who die for their country become like the immortal gods, and that, invisible like them, they still scatter their benefits on us. The ideas on immortality held in antiquity are often thus at once far from and near to our own—_near_ because they correspond to aspirations which are not antique or modern, but human, _far_ because the Olympians now have fallen into the deep gulf where lie dethroned deities. These ideas become more and more like the conceptions familiar to us as gradually their time grows later, and those generally admitted at the end of paganism are analogous to the doctrines accepted throughout the Middle Ages. I flatter myself, therefore, that when I speak to you of the beliefs in a future life held in Roman times I have chosen a subject which is not very remote from us nor such as has no relation to our present thought or is capable of interesting only the learned. We can here trace only the outlines of this vast subject. I am aware that it is always imprudent to hazard moral generalisations: they are always wrong somewhere. Above all, it is perilous to attempt to determine with a few words the infinite variety of individual creeds, for nothing escapes historical observation more easily than the intimate convictions of men, which they often hide even from those near them. In periods of scepticism pious souls cling to old beliefs; the conservative crowd remains faithful to ancestral traditions. When religion is resuming its empire, rationalistic minds resist the contagion of faith. It is especially difficult to ascertain up to what point ideas adopted by intellectual circles succeeded in penetrating the deep masses of the people. The epitaphs which have been preserved give us too scanty and too sparse evidence in this particular. Besides, in paganism a dogma does not necessarily exclude its opposite dogma: the two sometimes persist side by side in one mind as different possibilities, each of which is authorised by a respectable tradition. You will therefore make the necessary reservations to such of my statements as are too absolute. I shall be able to point out here only the great spiritual currents which successively brought to Rome new ideas as to the Beyond, and to sketch the evolution undergone by the doctrines as to the lot and the abode of souls. You will not expect me to be precise as to the number of the partisans of each of these doctrines in the various periods.
