“The most violent element in society is ignorance” is a saying that has been printed on many images. It was said by anarchist political activist and writer Emma Goldman (1869-1940)
 
Anarchists were frequently portrayed in the newspapers of the early 1900s as people promoting violence and destruction. Emma Goldman wrote in the essay “Anarchism: What It Really Stands For” (published in 1910 and 1911 by her Mother Earth Publishing Association, 210 East 13th Street, New York City):
   
“The emotions of the ignorant man are continuously kept at a pitch by the most blood-curdling stories about Anarchism. Not a thing too outrageous to be employed against this philosophy and its exponents. Therefore Anarchism represents to the unthinking what the proverbial bad man does to the child,—a black monster bent on swallowing everything; in short, destruction and violence.
 
“Destruction and violence! How is the ordinary man to know that the most violent element in society is ignorance; that its power of destruction is the very thing Anarchism is combating? Nor is he aware that Anarchism, whose roots, as it were, are part of nature’s forces, destroys, not healthful tissue, but parasitic growths that feed on the life’s essence of society. It is merely clearing the soil from weeds and sagebrush, that it may eventually bear healthy fruit.”

Someone has said that it requires less mental effort to condemn than to think. The widespread mental indolence, so prevalent in society, proves this to be only too true. Rather than to go to the bottom of any given idea, to examine into its origin and meaning, most people will either condemn it altogether, or rely on some superficial or prejudicial definition of non-essentials.
 
Anarchism urges man to think, to investigate, to analyze every proposition; but that the brain capacity of the average reader be not taxed too much, I also shall begin with a definition, and then elaborate on the latter.
 
ANARCHISM:—The philosophy of a new social order based on liberty unrestricted by man-made law; the theory that all forms of government rest on violence, and are therefore wrong and harmful, as well as unnecessary. The new social order rests, of course, on the materialistic basis of life; but while all Anarchists agree that the main evil today is an economic one, they maintain that the solution of that evil can be brought about only through the consideration of every phase of life,—individual, as well as the collective; the internal, as well as the external phases.
