There was an interesting exchange in the stem cell debate earlier this week between Harvard biologist George Daley and Senator Sam Brownback on when a human embryo acquires moral rights. According to Wired News, Brownback “persistently” asked Daley at what age he would decline to use an embryo for medical research. Wisely, Daley said he could not define when an embryo becomes a human being. “I think there would be consensus among scientists that it would be impossible to define that time,“ Daley said. “But I don’t think it’s at the age of the blastocyst.”Daley's "I can't hug an embryo" standard may prove to be a viable new tool for classifying certain life forms as not-fully-human and thus available for medical research, but his test may still pose perplexing questions in spite of it's Harvard origins. For example, many parents observe that huggable children gradually become unhuggable teenagers. While some parents would be relieved to know that their unhuggable teenagers can ethically be turned over to Harvard scientists for medical research, others feel unsettled about the matter and wonder if such post-natal terminations (retroactive abortions, I suppose) might somehow be "wrong." I suppose that further guidance from Dr. Daley might be helpful on this matter.
Wired writes:Brownback pressed further, asking him to envision his two children and determine at which point in their development it would be OK for scientists to perform research on them. “I can’t hug an embryo,“ Daley said. “I think (scientists) are comfortable with using the earliest microscopic ball of cells.“
Until science has fully settled the matter, I have a helpful question for teenagers: Have you hugged your parents today?
