If violence is answered by violence, the result is a physical struggle. Now, a physical struggle inevitably arouses in the minds of those directly and even indirectly concerned in it emotions of hatred, fear, rage and resentment. In the heat of conflict all scruples are thrown to the winds, and all the habits of forbearance and humaneness, slowly and laboriously formed during generations of civilised living, are forgotten. Nothing matters any more except victory. And when at last victory comes to one or other of the parties, this final outcome of physical struggle bears no necessary relation to the rights and wrongs of the case: nor in most cases, does it provide any lasting settlement to the dispute.
