In Robinson Crusoe, how does Crusoe's life change after living on the island?
The title character of Robinson Crusoe, Daniel Defoe's extraordinarily successful and influential 1719 novel, goes through several changes from the stress and responsibility of living on a deserted island. The most notable is his religion awakening; during a hallucinatory fever, Crusoe realizes that he has been very lucky in his shipwreck, and attributes that luck to Divine Intervention. Before the island, Crusoe's faith is spotty at best; after it, he is convinced that God's will follows and affects his life -- and everyone's life -- and he becomes somewhat of an evangelical, converting Friday to save his soul.
I began to instruct him in the knowledge of the true God; I told him that the great Maker of all things lived up there, pointing up towards heaven; that He governed the world by the same power and providence by which He made it; that He was omnipotent, and could do everything for us, give everything to us, take everything from us; and thus, by degrees, I opened his eyes.
(Defoe, Robinson Crusoe, eNotes eText)
Friday, being a product of his small island existence, has no reason to question Crusoe's certainty. It is interesting to note that after leaving the island, Crusoe's pious state returns to a baser interest in money and security; in the last chapter, the word "God" is not mentioned once. This reflects the pragmatic nature of Crusoe's repentance; he is far more interested in salvation while stranded, and much less so after he regains his comfortable life in civilization.
