I have heard what the talkers were talking, the talk of the beginnng and the end.For Leaves of Grass, Bartleby is yr friend
But I do not talk of the beginning or the end.
There was never any more inception than there is now,
Nor any more youth or age than there is now,
And will never be any more perfection than there is now,
Not any more of heaven or hell than there is now.
(section 14, line 31): bartleby
