John Burroughs has stated hat experimental study of animals in captivity is absolutely useless. Their character, their habits, their appetites undergo a complete transformation when torn from their soil in field and forest. With human nature caged in a narrow space, whipped daily into submission, how can we speak of its potentialities?

Freedom, expansion, opportunity, and, above all, peace and repose, alone can teach us the real dominant factors of human nature and all its wonderful possibilities.
