In this final chapter, I review the ground covered throughout this book. I then look to four different critiques of my argument: the social model, the phenomenological, the post-structuralist, and the post-human. I spend more time on the first and last critiques of my argument. I suggest that each of these different opposing perspectives can be overcome with a pragmatic perspective, that the good done by the philosophy explored to this point will justify its use, and that some minor alterations to Heidegger's work are similarly acceptable. I end by reflecting on this study, and think about its future importance.
