Poetry thus makes immortal all that is best and most beautiful in the world; it arrests the vanishing apparitions
which haunt the interlunations of life, and veiling them,
or in language or in form, sends them forth among
mankind, bearing sweet news of kindred joy to those with
whom their sisters abide-abide, because there is no
portal of expression from the caverns of the spirit which
they inhabit into the universe of things. Poetry redeems
from decay the visitations of the divinity in man.

Percy Bysshe Shelley
