Similarities and Differences Between Thoreau and McCandless

The similarities between Thoreau and Mc Candless are that they all like nature and want to be part of nature, pursue a life in nature. They are leaving human society to chasing a piece from being alone. The differences are more obvious to me. If we assume Thoreau and MCCandless has two different majors in college, then Thoreau must be an engineering student and McCanless might be an art student. The reason I said this is because Thoreau has a plan on his trip to nature. Same time, he also has knowlege prepared for his adventure. However, McCanless seems more to look for a peace in his mind because he just went to nature without a clear and brief plan. He wants to go then he goes, just like that.
