Many of the ideas and themes drawn out in the book are contradictory. For example: Abbey is dogmatically opposed in various sections to modernity that alienates man from their natural environment and spoils the desert landscapes, and yet at various points relies completely on modern contrivances to explore and live in the desert. Additionally, he expresses his deep and abiding respect for all forms of life in his philosophy, but describes unflinchingly his contempt for the cattle he herds in the canyons, and in another scene he remorselessly stones a rabbit, angry about rabbits' overabundance in the desert. Similarly, he remarks that he hates ants and plunges his walking stick into an ant hill for no reason other than to make the ants mad.
