From a Lecture by Sun Yat-sen on 3 August 1924

" After the European War the disciples of Marx all began to quarrel over matters of theory. The socialist parties of Germany, France and Russia had formerly been common followers of Marx and had been branches of the Internationale, but after the differences of opinion arose, they began to attack and to vilify each other and to accuse each other of disloyalty to Marxism. As a result of the attacks of this branch upon that and of this National Socialist Party upon that, Marx's theories began to be seriously questioned. "
