Published in 1892, St. George Jackson Mivart’s remarkably original article ‘Happiness in Hell’ was placed on the Index Librorum Prohibitorum almost immediately. In his article, Mivart proposed a solution to the problem of hell whose core contention is that hell is horrible only from a heavenly point of view. From a this-worldly point of view, by contrast, hell is a place of breathtaking felicity. In my opinion, this proposal has some striking merits, at least if it is updated and developed in certain respects. The purpose of this article is to reconstruct it, to reassess it, and to put it back on the table of eschatological ideas.
