Subject of a Life
The phrase subject of a life
was popularised by the American philosopher and animal rights advocate Tom Regan (1938 - ). What Regan means by subject of a life is that each animal is a unique life story, just as the story of your life is peculiar to you and no one else, and in this sense animals are like us. The expression subject of a life
helps convey to us a feeling for how individuals of other species are similar to us; we are all individuals in our own right going through the process of life.

Regan says we need to change our perception of animals from things - objects we use - to animals with lives of their own, independent of us and our use of them. An animal who is a subject of a life is a singular individual, has interests, learns from experience, has expectations that certain things will happen, has emotions like fear and pleasure, has painful and pleasurable experiences, and has a good or bad life. As Regan says, "All animals are somebody - someone with a life of their own." He says that even if subjects of a life cannot make moral choices or talk like humans, "what happens to them matters to them", so they should have moral rights.
"Surely every sentient being is capable of leading a life that is happier or less miserable than some alternative life, and hence has a claim to be taken into account."
Peter Singer. 1986. Applied Ethics. p227.
Although Regan has mammals in mind, you could extend the idea of being a subject of a life to all sentient creatures, and that would at least take into account birds, as well as many other species, like octopus.
A criticism of the idea of subject of a life
is that the list of features that constitute a subject of a life is arbitrary. You can add or subtract features to include or exclude species to suite your bias. Therefore, although the general idea of a subject of a life
is a sympathetic and descriptive expression, it may not bear up to examination too closely. We may still appreciate many good ideas that are good generally but difficult in detail.
