2. What is a moral lesson you get in Robinson Crusoe ?

I don't know if there is a moral lesson rather than themes to consider. The human condition is, in my opinion, the main theme. Robinson Crusoe is a meditation on the human condition, and an argument for challenging traditional notions about that condition. Finding himself alone in a deserted island, Crusoe struggles to maintain reason, order, and civilization. His "original sin" is his rejection of a conventional life. When he leaves England for a life on the high seas, he refuses to be "satisfied with the station wherein God and Nature hath placed" him.

Crusoe struggles with and eventually triumphs over nature. The book suggests that this struggle is at the heart of human nature: man is on earth to triumph and gain profit from nature. Any profit makes sense in this view of the world, whether that means getting just one plank out of a huge tree or building a boat too heavy to bring to the water. Once Crusoe is able to overcome his fear and subdue nature is rewarded handsomely.
