Yesterday the stranger said to me, ‘You may easily perceive, Captain Walton, that I have suffered great and unparalleled misfortunes. I had determined at one time that the memory of these evils should die with me, but you have won me to alter my determination. You seek for knowledge and wisdom, as I once did; and I ardently hope that the gratification of your wishes may not be a serpent to sting you, as mine has been. I do not know that the relation of my disasters will be useful to you; yet, when I reflect that you are pursuing the same course, exposing yourself to the same dangers which have rendered me what I am, I imagine that you may deduce an apt moral from my tale, one that may direct you if you succeed in your undertaking and console you in case of failure. Prepare to hear of occurrences which are usually deemed marvellous. (Shelley, Letter IV)
