There could be no better introduction to the present volume than these words of Mr. Hillquit, and it will, I think, be clear to the reader that the history of the labor movement during the last half-century fully sustains Mr. Hillquit's position. The problem of methods has always been a vital matter to the labor movement, and, for a hundred years at least, the quarrels now dividing syndicalists and socialists have disturbed that movement. In the Chartist days the "physical forcists" opposed the "moral forcists," and later dissensions over the same question occurred between the Bakouninists and the Marxists. Since then anarchists and social democrats, direct actionists and political actionists, syndicalists and socialists have continued the battle. I have attempted here to present the arguments made by both sides of this controversy, and, while no doubt my bias is perfectly clear, I hope I have presented fairly the position of each of the contending elements. Fortunately, the direct actionists have exercised a determining influence only in a few places, and everywhere, in the end, the victory of those who were contending for the employment of peaceable means has been complete. Already in this country, as a result of the recent controversy, it is written in the constitution of the socialist party that "any member of the party who opposes political action or advocates crime, sabotage, or other methods of violence as a weapon of the working class to aid in its emancipation shall be expelled from membership in the party."[D] Adopted by the national convention of the party in 1911, this clause was ratified at a general referendum of all the membership of the party. It is clear, therefore, that the immense majority of socialists are determined to employ peaceable and legal methods of action.
