Susumu Shimazono's view on human cloning

In 2001, the Council for Science and Technology Policy, Cabinet Office, was established in the government, and the Expert Research Commission on Bioethics was established in the Council. Its mission was to comprehensively discuss the ethical issues concerning human cloning, ES cells, and other reproductive technologies. In November 2003, a member of the Commission, Susumu Shimazono, professor of religious studies at the University of Tokyo, published a paper in a popular magazine in which he severely criticised the discussion in the Commission (10).

Shimazono first pointed out that “A Draft for Fundamental Thoughts on the Handling of Human Embryos (11) , circulated in the Commission on August 23, 2003, sought to compare two values, namely, “the value of a human embryo on which human dignity is reflected” and “the value created by scientific technology.” Two proposals, for and against promotion, were formulated in the draft. In the case of both ES cells and therapeutic human cloning, the proposal says that the value created by scientific technology clearly surpasses that of a human embryo.

Shimazono insisted that the Commission had never discussed whether or not research on a human embryo and ES cells violates “human [12/13] dignity”, and it had never discussed what “the sprout of human life” is and how it is different from “human life.” He argued that the artificial creation of an “animal-human chimeric embryo” might violate “human dignity,” but they had never discussed the ethical aspect of this handling. The draft uses the words “the sprout of human life” and “human dignity” many times, but the Commission had never considered the ethical and philosophical meaning of these terms in any depth. He laments the fact that the country, which seriously discussed the issue of brain death and organ transplantation, has not discussed this topic earnestly. He suspects that the consideration of economic aspects might have influenced the discussion in the Commission.
