“Enq: But this is more than simple delusion, it is an existence of insane hallucinations!
Theo: From your standpoint it may be, not so from that of philosophy. Besides which, is not our whole terrestrial life filled with such delusions? Have you never met men and women living for years in a fool’s paradise? And because you should happen to learn that the husband of a wife, whom she adores and believes herself as beloved by him, is untrue to her, would you go and break her heart and beautiful dream by rudely awakening her to the reality? I think not.
I say it again, such oblivion and hallucination – if you call it so – are only a merciful law of nature and strict justice. At any rate, it is a far more fascinating prospect than the orthodox golden harp with a pair of wings.
The assurance that “the soul that lives ascends frequently and runs familiarly through the streets of the heavenly Jerusalem, visiting the patriarchs and prophets, saluting the apostles, and admiring the army of martyrs” may seem of a more pious character to some.
Nevertheless, it is a hallucination of a far more delusive character, since mothers love their children with an immortal love, we all know, while the personages mentioned in the “heavenly Jerusalem” are still of a rather doubtful nature.
But I would, still, rather accept the “new Jerusalem”, with its streets paved like the show windows of a jeweler’s shop, than find consolation in the heartless doctrine of the Spiritualists.
The idea alone that the intellectual conscious souls of one’s father, mother, daughter or brother find their bliss in a “Summer land” – only a little more natural, but just as ridiculous as the “New Jerusalem” in its description – would be enough to make one lose every respect for one’s “departed ones”.
To believe that a pure spirit can feel happy while doomed to witness the sins, mistakes, treachery, and, above all, the sufferings of those from whom it is severed by death and whom it loves best, without being able to help them, would be a maddening thought.”
