A jilted Ismar Thiusen visits his friend Utis Estai who, through mesmerism, takes the two of
them to a 96th century puritanical utopian society where he is viewed by the locals as a
mentally ill man who believes he is from the 19th century.

According to the view of things above adverted to, the different stages in the history of
our race are not successive only, but are also co-existent and co-extensive with each
other. Just as in a block of marble, there is contained, not one only, but every possible
statue, though, of the whole number, only one at a time can be made evident to our
senses; so, in a given region of space, any number of worlds can co-exist, each with its
own population conscious of only that world, or set of phenomena, to which their ego is
attuned.
