It looks like this: the pro-choicer argues that human dignity requires bodily autonomy, and being pro-choice upholds human dignity; therefore, being pro-choice requires bodily autonomy. The pro-lifer argues that human dignity requires biological life, and being pro-life upholds human dignity; therefore, being pro-life requires biological life. That is precisely what is happening in the public abortion debate. Aquinas did not solely appeal to revelation to make the case for human dignity; he appealed to reason. If this book accomplishes one thing in the public dialogue on abortion, what would you want that to be?
