| Abstract: | ABSTRACT Because of the existence of severely defective humans it is commonly held that whatever consideration is due to all humans is also due to many other animals, and that therefore speciesism, or the readiness to prefer the interest of humans to those of other animals, is unjustified. After criticism of this reasoning a 'naturalised' speciesism, acknowledging, for example, the affinities between species, is articulated and defended. A key to this defence is the separation of the task of specifying morally significant differences between humans and other animals from the task of justifying the extension of consideration to defective humans. The conclusion is that more traditional vices than speciesism are chiefly to blame for the shabby treatment of animals by humans. |
