 Indeterminacy is the more serious charge, but critics maintain that even if public reason was only inconclusive with regard to many questions, this would also be a serious, perhaps fatal, objection to public reason. Some of the topics with regard to which critics allege public reason is either inconclusive or indeterminate include: abortion, stem-cell research, gay marriage, prostitution, justice for future generations, the treatment of animals, and other issues where critics allege getting the right moral or political answer depends upon religious or metaphysical claims about personhood, or else on controversial claims about human flourishing or the good life. Some critics believe that virtually all moral or political questions depend, to a certain extent, on truths about personhood, metaphysics, or human flourishing, and so these critics are likely to see the charge of incompleteness as a deep and pervasive problem for public reason.
