What is wrong with the way Crusoe treats Friday?

Crusoe looks upon Friday as a "creature" whom he will care for, giving him water, food, and clothing. The use of this word is somewhat degrading. It certainly indicates that Friday is a person of color. The fact that Robinson does not even try to learn Friday's actual name is testimony to the European supremacy theme that runs through the book. Crusoe has changed in appearance and occupation, but not intrinsically. He grants Friday his name as he would to any kind of pet. Thus Friday becomes, more or less, a little dog who follows Crusoe around. He is dressed in the image of his "master," and becomes a "manservant," willingly yet against his will at the same time, because he understands no English. Saving Friday gives the narrator the chance to play God and be in control of something concrete. He is glorifying his religion and himself by saving a life. Animals can only be "subjects" in a minimal sense. The appearance of Friday will allow Crusoe to live out his role as ruler of the island.
