Mary Anne Warren


Mary Anne Warren was an American writer and philosophy professor, noted for her writings on the issue of abortion.
Her essays have sometimes been required readings in academic courses dealing with the abortion debate and they are frequently cited in major publications like Peter Singer's The Moral of the Story: An Anthology of Ethics Through Literature and Bernard Gert's Bioethics: A Systematic Approach. She was sometimes described as a feminist, largely due to her pro-choice writings.
Warren also wrote on the implications of sex selection and about animal treatment. She was a professor of philosophy at San Francisco State University for many years.
Mary Anne Warren died on August 9, 2010 from cancer, aged 64.

Criteria of personhood

In response to whether a thing can be said to be a person, and so have moral standing, Warren suggested the following criteria:
  1. Consciousness, and in particular the capacity to feel pain;
  2. Reasoning ;
  3. Self-motivated activity ;
  4. The capacity to communicate, by whatever means, messages of an indefinite variety of types, that is, not just with an indefinite number of possible contents, but on indefinitely many possible topics;
  5. The presence of self-concepts and self-awareness, either individual or racial, or both.
  6. Moral agency
She stated that at least some of these are necessary, if not sufficient, criteria for personhood. She argued that fetuses do not meet any of these criteria, therefore they cannot be persons, and cannot have moral standing, and so abortion is acceptable.
