[1] "Though in its most general sense the substance and matter of all
fine art is the same, issuing from the common source of the human desire
for expression, yet the region of fancy corresponding to each medium of
utterance is molded by intercourse with that medium, and acquires an
individuality which is not directly reducible to terms of any other
region of aesthetic fancy. Feeling, in short, is modified in becoming
communicable; and the feeling which has become communicable in music is
not capable of re-translation into the feeling which has become
communicable in painting. Thus the arts have no doubt in common a human
and even rational content--rational in so far as the feelings which are
embodied in expression, for expression's sake, arise in connection with
ideas and purposes; but each of them has separately its own peculiar
physical medium of expression and also a whole region of modified
feeling or fancy which constitutes the material proper to be expressed
in the medium and according to the laws of each particular art."--B.

of the Aristotelian Society_).
