Mary Anne Warren provides a well‐known defense of the liberal position in the abortion debate, yet her argument is subject to the objection that it implies that infanticide is morally permissible. In a postscript to her original article, Warren argues that her position does not commit her to the moral acceptability of infanticide. I argue that the reasoning Warren presents in her postscript on infanticide undermines her original main argument in support of the liberal view: she cannot use this argument (...) to both defend the liberal view on abortion and establish that infanticide is morally wrong.
