what caused chris to embark on is journey

McCandless describes what he is looking for on his odyssey, particularly on the Alaska trip, as “ultimate freedom.” It would seem that this largely represents, to him, freedom from other people’s rules and authority over him. Throughout his whole life he finds authority particularly oppressive, especially when exercised by anyone who he feels only has such power over him for arbitrary reasons. To live completely alone, in a world where the only laws he feels the need to follow are those of nature, is to him ultimate freedom.
