They emphasize those qualities which separate human beings from animals, implying that these qualities prove moral significance and thus that the absence of these qualities would deny such significance. Inherent in the discussion of the moral significance of animals is that human actions will be determined by the outcome of the argument. Human beings tend to view animals as a resource that exists for human use:

Among the uniquely human attributes usually evoked in such discussions are reasoning ability, complex language, and self-consciousness (or our awareness of our own existence). Sentience is also discussed but is, of course, not a uniquely human attribute, since the ability to feel pain is possessed by animals as well. Schopenhauer considered the matter and compared human beings to animals. He noted that abstract concepts are possessed only by human beings, while intuitive presentations are common to both human beings and higher animals:
