In doing so, he anticipates the pro-life rebuttal to his argument. In short, he recognizes this opposing view as a means of gaining further support for his position. He basically says, “I understand the ideological blocks of those against stem cell research, but my argument is superior because it promotes the 'health and well-being of the many' and the 'good of all humanity.'” In his rebuttal, Richard Doeflinger, argues that Reagan did not advocate embryonic stem cell research in the speech, but rather more closely described "human cloning" to treat disease or injury. The purpose of his argument is to highlight the limitations of Reagan's argument and present examples that demonstrate that there are other viable treatments beyond stem cell research for debilitating conditions such as Parkinson's and juvenile disease.
