"Few people have any adequate conception of the cartoon as a factor in political agitation and social progress...A score of pages of the most graphic writing could not be so effective...It is one of the most subtle of educational forces. Its evolution has been slow under capitalism, but is being rapidly accelerated with the growth of Socialism. The true art of the untrammelled cartoonist is now being developed and he will be one of the most inspiring factors in the propaganda of the revolution. No more is the cartoonist compelled to prostitute his genius and traffic in his art. The prizes of capitalism no longer tempt him; its chains of dependence no longer hold him captive...[the social cartoonist] is the social conscience, the social sense of duty, the social love and the social inspiration, and his the thrillingly joyous and self-imposed task to redeem the art of pictorial appeal from gross and sordid commercialism and consecrate it to the cause of freedom and the service of humanity."
