This shows us that like is drawn to like, to what it has affinity with. It is for this reason that the nations and races have their particular characteristics and attributes; because for centuries people of like character and like qualities have collected together, forming groups. The French are unlike the English, who again are different from the Swedes; the Swedes differ from the Germans. It is not difficult for a person whose intelligence is trained in this direction, to distinguish at a glance a Belgian from a Frenchman, a German from an Italian, even in a crowd.
