The Process of Labeling (or reflecting upon) others.

George Fox, in a letter to Collonell Bennett, (who apparently was the first to use the term Quaker to reference The Children of Light) writes about the nature of the process of Naming reflecting upon other people.

... soe thou hast bine one of the beasts heads, that gives the names which doe not the saints nor Apostles nor Christ teach Any such docktrine, that the saints should doe soe, but all this Giving of names Among people is come upp Among you from them that are Apostatised, the divells geneation and the dragons power and soe to cause the people to give names on to Another, wherby to Envy one another and to hate one Another, and this they are Ignorant off that they ware all off one blood and mould that dwell uppon the face of the whole Earth, and Ignorant of the doctrine of Christ and the Apostles which is Love, and stopts that which causes Envy and hatreed, soe that which went out of the truth and aboad not in truth is the Enmyty is the cause of people hating one Another, and the quakers now in scorne called soe shall make the nations Tremble.

Fox here observes that entering into the process of naming, labeling, or reflecting upon other people is the cause of envy and hatred between people. And that Love, stops the process of naming which is the cause of Envy and Hatred.
