because he does not wholly sever connections with this same physical
world, but is continually hovering about it, like a homesick ghost.

Like the plain man, the philosopher gives the poet a chance to vindicate
his usefulness. Plato's challenge is not so age-worn that we may not

charms, but we may not on that account betray the truth.... Shall I
propose, then, that she be allowed to return from exile, but on this
condition only, that she makes a defense of herself in lyrical or some
other meter? And we may further grant to those of her defenders who are
lovers of poetry and yet not poets the permission to speak in prose on
her behalf. Let them show not only that she is pleasant but also useful
to states and to human life, and we will listen in a kindly spirit.
[Footnote: _Republic_, Book X, 607.]

One wonders why the lovers of Poetry have been so much more solicitous
for her cause than Poetry herself has appeared to be. Aristotle, and

last century and a half there are occasional passages which give the
impression that Poetry, with childishly averted head, is offering them
