Pure science must be the same to all orders of created beings, but, as
far as our knowledge extends, the physical organization of humanity is
required for a perception of the beauties of art: therefore physical
excitement must be united with mental, in proportion as the work of art
is successful. Do not then hope ever to be able to study poetry without
a quickened pulse and a flushing cheek; you may as well leave it alone
altogether, if it produces no emotion. It must be either rhyme and no
poetry, or to you poetry can be nothing but rhyme.

Think not, however, that I do wish you to leave it alone altogether;
nothing could be farther from my purpose.

There is some old saying about fire being a good servant, but a bad

feeling--as long as you are able to prevent its rousing your temper to
an uncontrollable degree of susceptibility--as long as you can return
from an ideal world to the lowly duties of every-day life with a steady

precautions, either more or less: you must not, for the sake of a few
superable difficulties, resign the otherwise unattainable refinement
effected by poetry. Besides, its exalting and ennobling influence, if
