Ink is the great missive weapon

"Now, it must here be understood that ink is the great missive weapon in all battles of the learned, which conveyed through a sort of engine called a quill, infinite numbers of these are darted at the enemy by the valiant on each side, with equal skill and violence, as if it were an engagement of porcupines. This malignant liquor, which are gall and copperas; by its bitterness and venom to suit in some degree, as well as to format, the opinions of the combatants."

So said Swift in his Battle of the Book of 1604.

And now, I with my virtual ink on your screen shall the battle shall be studied.
