Proportionate Retaliation, or Reciprocity of services,--as in the case of Commercial Exchange, measured through the instrument of money, with its definite value,--is set forth as the great bond of society.

Just dealing is the mean between doing injustice and suffering injustice (V.).

Justice is definitely connected with Law, and exists only between citizens of the State, and not between father and children, master and slave, between whom there is no law proper, but only a sort of relation analogous to law (VI.).
