Having returned safely home, Crusoe marries and starts a family. But despite his prosperous life, he finds nothing to challenge him and suffers from a burning desire to return to sea. Although his wife begs him not to go, Crusoe and his man Friday set sail. When they reach the island, they are surprised to find that things have changed dramatically. When Crusoe and Friday set out for the mainland, they are attacked by vicious cannibals and Friday is killed. Overwhelmed with grief for the loss of his faithful servant and friend, Crusoe embarks on a long voyage around the world. His travels take him to far-flung places from Brazil and Madagascar to Siberia and China. As he continues to journey, it becomes clear that he is happiest when wandering, and we begin to wonder if he will ever return home again.
That homely proverb, used on so many occasions in England, viz. "That what is bred in the bone will not go out of the flesh," was never more verified than in the story of my Life. Any one would think that after thirty–five years' affliction, and a variety of unhappy circumstances, which few men, if any, ever went through before, and after near seven years of peace and enjoyment in the fulness of all things; grown old, and when, if ever, it might be allowed me to have had experience of every state of middle life, and to know which was most adapted to make a man completely happy; I say, after all this, any one would have thought that the native propensity to rambling which I gave an account of in my first setting out in the world to have been so predominant in my thoughts, should be worn out, and I might, at sixty one years of age, have been a little inclined to stay at home, and have done venturing life and fortune any more. Nay, farther, the common motive of foreign adventures was taken away in me, for I had no fortune to make; I had nothing to seek: if I had gained ten thousand pounds I had been no richer; for I had already sufficient for me, and for those I had to leave it to; and what I had was visibly increasing; for, having no great family, I could not spend the income of what I had unless I would set up for an expensive way of living, such as a great family, servants, equipage, gaiety, and the like, which were things I had no notion of, or inclination to; so that I had nothing, indeed, to do but to sit still, and fully enjoy what I had got, and see it increase daily upon my hands. Yet all these things had no effect upon me, or at least not enough to resist the strong inclination I had to go abroad again, which hung about me like a chronic distemper. In particular, the desire of seeing my new plantation in the island, and the colony I left there, ran in my head continually. I dreamed of it all night, and my imagination ran upon it all day: it was uppermost in all my thoughts, and my fancy worked so steadily and strongly upon it that I talked of it in my sleep; in short, nothing could remove it out of my mind: it even broke so violently into all my discourses that it made my conversation tiresome, for I could talk of nothing else; all my discourse ran into it, even to impertinence; and I saw it myself. I have often heard persons of good judgment say that all the stir that people make in the world about ghosts and apparitions is owing to the strength of imagination, and the powerful operation of fancy in their minds; that there is no such thing as a spirit appearing, or a ghost walking; that people's poring affectionately upon the past conversation of their deceased friends so realises it to them that they are capable of fancying, upon some extraordinary circumstances, that they see them, talk to them, and are answered by them, when, in truth, there is nothing but shadow and vapour in the thing, and they really know nothing of the matter.
