Desert rat Edward Abbey once said, "Growth for the sake of growth is the ideology of the cancer cell." Well, progress for the sake of progress seems also to be a very human ideology. We separate ourselves from the other animals, but we are merely a different species of animal, albeit the most destructive species. We like to think of ourselves as exalted and intelligent persons, who have dominion over all the other animals, but the truth is that we are deluding ourselves. Thanks to evolution though, we may be stuck with our delusions, because reality is a lot less comfortable. A very thought provoking book, that may change the way you think about yourself.
