Abstract
If respect for the dignity of non-human creatures is to be an element of public policy it needs, as a first step, to be assimilated into the common morality. It is suggested that such respect may be based on several philosophical premises. Limiting the discussion to sentient animals, the paper reviews three of these: the concept of animal telos; the application of Rawlsian contractarianism to the case of non-human animals as moral patients; and human attitudes to animals in the light of virtue theory. Consideration is then given to the extent to which, by accommodating respect for the dignity of animals within the common morality, these principles might find more substantive expression in public policy.
