Some good solid common sense from Australian ethicist John Mackie:
"It is much easier, and commoner, to display a self-sacrificing love for some of one’s fellow men if one can combine this with hostility to others."
— J.L. Mackie, Ethics: Inventing Right and Wrong (Penguin 1977), p. 132.
"People will be able more fully to get what they desire if they are made to desire what they are going to get."
— Ibid., p. 147.
