Bolingbroke, writing to Swift, says, "It is now six in the morning; I recall the time--and am glad it is over--when about this hour I used to be going to bed surfeited with pleasure, or jaded with business; my head often full of schemes, and my heart as often full of anxiety. Is it a misfortune, think you, that I rise at this hour refreshed, serene, and calm: that the past and even the present affairs of life stand like objects at a distance from me, where I can keep off the disagreeable, so as not to be strongly affected by them, and from whence I can draw the others nearer to me?" De Foe moralizes in memorable language: "I know too much of the world to expect good in it, and have learned to value it too little to be concerned at the evil. I have gone through a life of wonders, and am the subject of a vast variety of providences. I have been fed more by miracles than Elijah when the ravens were his purveyors. I have some time ago summed up the scenes of my life in this distich:-- 'No man has tasted differing fortunes more; And thirteen times I have been rich and poor.' In the school of affliction I have learnt more philosophy than at the academy, and more divinity than from the pulpit. In prison I have learnt that liberty does not consist in open doors and the egress and regress of locomotion. I have seen the rough side of the world as well as the smooth; and have in less than half a year tasted the difference between the closet of a king and the dungeon of Newgate. I have suffered deeply for cleaving to principles, of which integrity I have lived to say, none but those I suffered for ever reproached me with."
