For Books are not absolutely dead things, but do contain a potency of life in them to be as active as that soul was whose progeny they are; nay they do preserve as in a vial the purest efficacy and extraction of that living intellect that bred them. I know they are as lively, and as vigorously productive, as those fabulous Dragons teeth; and being sown up and down, may chance to spring up armed men. And yet on the other hand, unless wariness be used, as good almost kill a Man as kill a good Book; who kills a Man kills a reasonable creature, Gods Image; but he who destroys a good Book, kills reason it self, kills the Image of God, as it were in the eye. Many a man lives a burden to the Earth; but a good Book is the precious life-blood of a master spirit, embalmed and treasured up on purpose to a life beyond life….We should be wary therefore what persecution we raise against the living labors of public men, how we spill that seasoned life of man preserved and stored up in Books; since we see a kind of homicide may be thus committed, sometimes a martyrdom, and if it extend to the whole impression, a kind of massacre, whereof the execution ends not in the slaying of an elemental life, but strikes at that ethereal and fift essence, the breath of reason it self, slays an immortality rather then a life.
–John Milton (1608-1674), Areopagitica (Hat tip: AH)
Hebrews 4:12
For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart.
