A man may be 'twixt ape and Plato;
'Tis the man who with a bird,

All its instincts; he hath heard
The lion's roaring, and can tell
What his horny throat expresseth,
And to him the tiger's yell
Comes articulate and presseth
On his ear like mother tongue." *

and they seem to have an attraction for minds of the same cast.
They were both exposed to the same influences, those revolutionary
influences in literature and religion which inaugurated a new period.
Yet there is a great contrast as well as a great similarity
between them, and it is interesting to remark the different
spiritual results in the case of these two different minds
subjected to conditions so similar in general, though different
in detail. Both felt the same need, the need of ESCAPE,
desiring to escape from the actual world in which they perceived
more evil than good, to some other ideal world which they had
to create for themselves. This is the point of their similarity;
their need and motive were the same, to escape from the limitations
of the present. But they escaped in different directions,
Keats into the past where he reconstructed a mythical Greek world
after the designs of his own fancy, Shelley into a future where
he sought in a new and distant era, in a new and distant world,
a refuge from the present. We may compare Keats's `Hyperion'
with Shelley's `Prometheus', as both poems touch the same idea --
