And thus when by Poetry, or when by Music,
the most entrancing of the poetic moods, we find           melted into
tears, we weep then, not as the Abbate Gravina supposes, through excess
of pleasure, but through a certain petulant, impatient sorrow at our
inability to grasp now, wholly, here on earth, at once and for ever,
those divine and rapturous joys of which _through' _the poem, or
_through _the music, we attain to but brief and indeterminate glimpses.
