In a Time magazine essay, Charles Krauthammer tells why he does not support stem-cell research "from embryos created purposely and wantonly for nothing but use by science":

When I was 22 and a first-year medical student, I suffered a spinal-cord injury. I have not walked in 32 years. I would be delighted to do so again. But not at any price. I think it is more important to bequeath to my son a world that retains a moral compass, a world that when unleashing the most powerful human discovery since Alamogordo—something as protean, elemental, powerful and potentially dangerous as the manipulation and re-formation of the human embryo—recognizes that lines must be drawn and fences erected.
