Crusoe’s arrival on the island does not make him revert to a brute existence controlled by animal instincts, and, unlike animals, he remains conscious of himself at all times. Indeed, his island existence actually deepens his self-awareness as he withdraws from the external social world and turns inward. The idea that the individual must keep a careful reckoning of the state of his own soul is a key point in the Presbyterian doctrine that Defoe took seriously all his life. We see that in his normal day-to-day activities, Crusoe keeps accounts of himself enthusiastically and in various ways. For example, it is significant that Crusoe’s makeshift calendar does not simply mark the passing of days, but instead more egocentrically marks the days he has spent on the island: it is about him, a sort of self-conscious or autobiographical calendar with him at its center. Similarly, Crusoe obsessively keeps a journal to record his daily activities, even when they amount to nothing more than finding a few pieces of wood on the beach or waiting inside while it rains. Crusoe feels the importance of staying aware of his situation at all times. We can also sense Crusoe’s impulse toward self-awareness in the fact that he teaches his parrot to say the words, “Poor Robin Crusoe. . . . Where have you been?” This sort of self-examining thought is natural for anyone alone on a desert island, but it is given a strange intensity when we recall that Crusoe has spent months teaching the bird to say it back to him. Crusoe teaches nature itself to voice his own self-awareness.
