Thinking about cloning: a reply to Judith Thomson

Opponents of human cloning typically argue for the prohibition of therapeutic cloning and a permanent prohibition of reproductive cloning, even if a safe cloning technology should become available. In a recent article in this journal, "Legal and Ethical Problems of Human Cloning" (2000) 8 JLM 31, Judith Thomson develops an ethico-legal analysis that would justify prohibitions or restrictions on both therapeutic and reproductive cloning, irrespective of any safety issue. This article criticises Thomson's analysis in detail and suggests, in particular, that it relies upon an intellectually unacceptable understanding of personhood.
