A Tempered Rationalism for a Tempered Yuck Factor-Using Disgust in Bioethics.

When it comes to invasive manipulation of animals on the biological level, reactions of disgust are common and often influential on people's moral judgments. As a case in point, the Belgian Blue, a breed of hyper-enhanced cattle which will serve as a case study for the present article, has historically been met with revulsion. Traditionally, in bio- and animal ethics, this 'yuck factor,' has been denied any productive role in proper moral justification, since rationalism is still a dominant paradigm in those disciplines.
