Coming immediately after allusions to the treacherous Ulysses and murderous Lady Macbeth,
                     this injunction bears the stamp of one who, using like rhetoric, exhorted his comrades
                     to throw off a similar despondency: "Awake, arise, or be for ever fallen!" (Paradise
                     Lost, I.330). Satan, too, standing on his perseverance in a lost cause, represents
                     himself as being      
     one who brings 
 A mind not to be changed by place or time. 
 The mind is its own place, and in itself 
 Can make a Heaven of Hell, a Hell of Heaven. 
 What matter where, if I be still the same. . . (I.252-256).
