A significant aspect of anarchism, which brings it close to Russian nihilism and in the minds of some people is responsible for the erroneous identification of the two, is individual terrorism. Individual acts of violence, known especially in the last century as “propaganda by deed,” have been regarded by some anarchists as part and parcel of the over-all revolutionary activity which is to culminate in the overthrow of the existing social system by acts of mass violence. There were and are anarchists of different schools opposed to violence as a means towards the establishment of an anarchist society, and they include not only religious anarchists like Leo Tolstoy and individualists like Benjamin Tucker, but also many of those who at one time or another could be classed as anarchist communists, for instance, Francisco Ferrer, Louisa S. Bevington, and Gustav Landauer. The so-called philosophical anarchists are also opposed to violence, if by them are meant people who believe in the possibility or at least the desirability of realizing the ideals of anarchism but do not accept the usual anarchist analysis of the existing system or the methods generally advocated by anarchist groups for the achievement of anarchism. Thus Godwin, Tolstoy, and Tucker, could be included in this group, and among our contemporaries Bertrand Russell.
In the present century anarchists have almost ceased in theory and practice to view individual terrorism as important. Violent acts have been usually perpetrated by people who had practically no significance as thinkers and writers. Alexander Berkman is probably the only notable exception here, while men like Kropotkin, fortunately for anarchism, propagated anarchist ideas by the written and spoken word rather than by “deed.”
