"Vice, as it groweth in age, so it improveth in stature and strength...so we shall dwindle and prove more impotent, for it feedeth upon our vitals, and thriveth by our decay; it waxeth mighty by stripping us of our best forces, by enfeebling our reason, by perverting our will, by corrupting our temper, by debasing our courage, by seducing all our appetites and passions to a treacherous compliance with it; every day our mind groweth more blind, our will more rusty, our spirit more faint, our passions more headstrong and untamable; the power and empire of sin do strangely by degrees encroach, and continually get ground upon us, till it hath quite subdued and enthralled us. First we learn to bear it; then we come to like it; by and by we contract a friendship with it; then we dote upon it; at last we become enslaved to it in bondage."
-- Isaac Barrow (ca. 1650)
