Lately in a biomedical ethics class I am enrolled in, we've been discussing the underlying values and moral issues involved in testing on non-human animals. Most ethical theories advocating the use of animals in research run into trouble when they attempt to draw a line between humans, and other animals. When attempting to say that non-human animals are not conscious beings, or do not have the capacity for understanding rights, or whatever else you might attempt to say in this line of belief, you run into trouble when compared to the severly disabled or non-conscious humans who should fall into the same category. Is it then legitimate to test on the disabled? (I don't believe this, just want to know your thoughts and justifications) What are your thoughts on this, is there a line that can be drawn between the severly disabled and non-human animals such as primates, or even mammals in general? I myself am an immunology major, and as such I have tested on mice etc. in the lab. I also have mice that I keep as pets at home, which I tend to look at from a different angle than those I rely on in the lab for my studies. Do you believe this to be hypocritical?
