Animals... don't have a sense of time. You just have to do things over and over with animals until they happen to do it right because they don't really know what you want. View quotes by Bruce Greenwood
Certainly it is wrong to be cruel to animals and the destruction of a whole species can be a great evil. The capacity for feelings of pleasure and pain and for the form of life of which animals are capable clearly impose duties of compassion and humanity in their case. [A Theory of Justice] View quotes by John Rawls
