Whatever the specific reasons are for abortion, most feminists believe that the women concerned are in the best position to judge whether abortion is the appropriate response to a pregnancy. Because usually only the woman choosing abortion is properly situated to weigh all the relevant factors, most feminists resist attempts to offer general, abstract rules for determining when abortion is morally justified. Women's personal deliberations about abortion involve contextually defined considerations that reflect their commitments to the needs and interests of everyone concerned, including themselves, the fetuses they carry, other members of their household, and so forth. Because no single formula is available for balancing these complex factors through all possible cases, it is vital that feminists insist on protecting each women's right to come to her own conclusions and resist the attempts of other philosophers and moralists to set the agenda for these considerations. Feminists stress that women must be acknowledged as full moral agents, responsible for making moral decisions about their own pregnancies. Women may sometimes make mistakes in their moral judgments, but no one else can be assumed to have the authority to evaluate and overrule their judgments.
