From the introduction by Stanley Kunitz:
Blake speaks more directly to us, anticipating the issues, conflicts,
and anxieties of the modern world, than any of his contemporaries. It
could be argued that he dared, in fact, to be the first modern poet. . .
.
Above all, Blake teaches us that the imagination is a portion of the
divine principle, that "Energy is Eternal Delight," and that "everything
that lives is Holy." Human liberty and imagination have never been
better served.
