The very essence of truth is plainness and brightness; the darkness and crookedness is our own. The wisdom of God created understanding, fit and proportionable to truth, the object and end of it, as the eye to the thing visible. If our understanding have a film of ignorance over it, or be blear with gazing on other false glitterings, what is that to truth?
John MiltonHe 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 Milton
