Hedonistic utilitarianism and Regan's rights view are paradigm cases of what philosophers take to be animal welfare and animal rights views, respectively.

• Utilitarianism (right actions and institutions maximize aggregate happiness), plus

• hedonistic conception of happiness (feeling pleasure and avoiding pain).

• Rejection of utilitarian justifications for harming individuals, where

• harm is conceived as diminution in the capacity to form and satisfy desires, and

• the miniride and worse-off principles are used to decide whom to harm where h arm is inevitable.
