The distrust of eternity at which our friend hints is perhaps the painfulest of his newly discovered differences between youth and age. Resting so serenely as it does in practically unlimited time, with ideals and desires which scarcely vary from year to year, youth has no fears of infinity. It is not afraid but it shall have abundant occupation in the aeons before it, or that its emotions or volitions shall first be exhausted. Its blithe notion of immortality is that it is immortal youth. It has no conception of age, and could not imagine an eternity of accomplished facts. It is, perhaps, for this reason that doubt of immortality never really comes to youth. One of the few things which our friend still believes is that every sceptic who deals honestly with his only history must be aware of an hour, almost a moment, of waning youth, when the vague potentiality of disbelief became a living doubt, thence-forward to abide with him till death resolve it. Endless not-being is unthinkable before that time, as after it endless being is unthinkable. Yet this unthinkable endless being is all that is left to age, and it is in the notion of it alone that age can get back to the long, long thoughts in which is surcease from unrest. Our old friend may accuse us of proposing the most impossible of paradoxes when we invite him to take refuge from his whirling ideals, not in an unavailing endeavor to renew the conditions of youth in time, but in the forecast of youth in eternity. We think that the error of his impatience, his despair with the state he has come to here, is largely if not wholly through his failure to realize that he is not going to wake up old in some other being, but young, and that the capacity of long, long thoughts will be renewed in him with the renewal of his life. The restlessness of age, its fickleness, its volatility, is the expression of immense fatigue. It tosses from side to side and tries for this and that like a sick man from sheer weakness; or, rather, if the reader prefers another image, it is like some hapless wild thing caught by rising floods on a height of land which they must soon submerge, and running incessantly hither and thither as the water more narrowly hems it in.
