He that can apprehend and consider vice with all her baits and seeming pleasures, and yet abstain, and yet distinguish, and yet prefer that which is truly better, he is the true wayfaring Christian. I cannot praise a fugitive and cloistered virtue, unexercised and unbreathed, that never sallies out and sees her adversary, but slinks out of the race, where that immortal garland is to be run for, not without dust and heat. Assuredly we bring not innocence into the world, we bring impurity much rather: that which purifies us is trial, and trial is by what is contrary.
John MiltonA gulf profound as that Serbonian bog Betwixt Damiata and Mount Casius old, Where armies whole have sunk: the parching air Burns frore, and cold performs th' effect of fire. Thither by harpy-footed Furies hal'd, At certain revolutions all the damn'd Are brought, and feel by turns the bitter change Of fierce extremes,-extremes by change more fierce; From beds of raging fire to starve in ice Their soft ethereal warmth, and there to pine Immovable, infix'd, and frozen round, Periods of time; thence hurried back to fire.
John Milton
