Robinson's thoughts and changes during his stay.

I think that Robinsons thoughts changed since he first arrived on the island. At the beginning, he was really sad and did everything he could just for survival. He was blaming himself for his misery. But after his illness and his hallucination, he began to think about his relationship with God, and finally admitted that his punishment on the island was a consequence of all his bad precedent behaviors. Fortunately, after the several years he spent there, he began to enjoy his situation, looking at the island like his kingdom. He now had his bower, his plantations, his cattle... At this time, he was just missing the human communication, but his periods of bad mood occured more rarely compared to when he arrived. From a divine punishment, he noticed that his situation was good, having almost everything he needs, thanks to many improvements. [With the experience of staying on the island, he learned a lot and was finally able to create/produce whatever he needed (even if it was after some failures), becoming self sufficient.]
