My focus will be the relationship between the idea of a human nature, and the acceptance of biotechnology's (mostly neuro-pharmologicals such as ritalin and prozac, but also more familar imrpovment drugs such as steroids) use for curing what we see as deficiencies (ADHD, depression, etc) but not for imrpoving "normal" human beings beyond their born capabilities. I will be using Fukuyama's Our post human future as my text for analysis, with help from Dawn, Canguilhen's Normal and the Pathological, and maybe some other theory texts to get a grasp on what we think human nature is, and where it comes from. My analysis will mostly be on the use of the rhetoric of human nature as an argument against improving humans beyond their "natural" capabilities. Dawn and Canguilhen will function as criticisms of this rhtetoric.
