He wanted to escape things that he did not want or need. Society as he knew it was sick and consisted of false security, material excesses, judgment, and control, all distractions that kept people from the truth of existence. Money and power was an illusion. Careerism and money seemed only to embolden blindness. His over indulgence in personal desires to find truth enticed him, with swift decision, to sever all current ties just as precisely and deliberately as a newborn infant is cut from its umbilical cord.
For nearly two years Christopher Johnson McCandless, AKA Alexander Super Tramp, lived a footloose life. He had escaped to absolute freedom. He reveled in his newfound ability to get by without depending on much of anything. His days were more exciting when hew as penniless. This was not an aimless journey for Alex however, what he wanted more than anything, “… than love, than money, than faith, than fame, than fairness…” he sought truth. To him “it is important in life, not necessarily to be strong, but to feel strong. To measure yourself at least once; to find yourself at least once in the most ancient of human conditions, facing the blind death stone alone with nothing to help you but your hands and your own head.” This belief may explain why he never attempted to contact his family during his journey. His strong need to do this completely on his own kept him isolated from those who would undoubtedly, and forcefully, lend a helping a hand. And that in itself was the last thing he wanted.
Away from the falseness of society Alexander Super Tramp greatly contributed to the society he so despised, probably without even realizing it. Along his road to the wild he encountered several people who truly benefited from meeting him. While he disowned his own family and his own name, he was a surrogate son and brother to others who had also been separated from their loved ones. His momentary presence in their lives brought to them joy and forgiveness. Perhaps Alexander Super Tramp was so blinded by his own quest to save himself that he was unable to see he was a savior to many along the way.
