Leon Kass’s thinking about the cloning of human beings is that, according to him, he would depersonalize human reproduction, have significant influence on future generations, and eventually lead to the degradation of man. 4

His critics accuse Kass of having completed the Council with anti-abortionists and opponents of embryonic stem cell research, and rejected those people who disagreed with him, such as Elizabeth Blackburn . 5
