In his Introduction to Animal Rights, Gary Francione tells us, “There is a great deal of confusion surrounding the concept of rights.”
Something that Gary doesn’t really clear up.
He says that:
a right is a particular way of protecting interests. To say that an interest is protected by a right is to say that the interest is protected against being ignored or violated simply because this will benefit someone else. We can think of a right of any sort as a fence or a wall that surrounds an interest and upon which hangs a “no trespass” sign that forbids entry, even if it would be beneficial to the person seeking that entry.
