Philip points out how Sharikov’s apparently principled belief in equality contradicts his actual behavior: he’s selfish and doesn’t recognize other people’s rights or dignity. In contrast, Philip openly declares that he believes in a natural hierarchy of different kinds of people (and animals). Of course, he puts cultivated aristocrats like himself at the top, and he puts uneducated brutes like Sharikov at the bottom. In fact, Sharikov
did mostly obey Philip and accept his own inferiority when he was a dog. But just like the Revolution convinced the working classes that they deserved equality, Sharikov’s operation has convinced him that he no longer owes anything to Philip.
