No feats of heroism are needed to achieve the greatest and most important changes in the existence of humanity; neither the armament of millions of soldiers, nor the construction of new roads and machines, nor the arrangement of exhibitions, nor the organization of workmen's unions, nor revolutions, nor barricades, nor explosions, nor the perfection of aerial navigation; but a change in public opinion. And to accomplish this change no exertions of the mind are needed, nor the refutation of anything in existence, nor the invention of any extraordinary novelty; it is only needful that we should not succumb to the erroneous, already defunct, public opinion of the past, which governments have induced artificially; it is only needful that each individual should say what he really feels or thinks, or at least that he should not say what he does not think.
