ABSTRACT
Rollin addresses the notion of telos , the essence and purpose of a creature, and proposes that there is no direct reasoning to argue that the notion of telos in animals and the Maxim to Respect Telos should preclude genetic engineering of animals. He notes that for domestic animals, each proposed modification should be assessed in relation to the Principle of Conservation of Welfare. For nondomestic animals, he believes that such modifications also may be valuable. He exercises proceeding cautiously so as to avoid possible ecological impacts or affecting other animals adversely.
