movement of the constructive intellect."[25] Socialism is rich in promises, and its claims to our consideration and support are manifold. Are these claims justified or not? Are the Socialists or the Anti-Socialists right in their conception of Socialism? The Socialists maintain that all opposition to Socialism is based either on self-interest or ignorance, and principally upon the latter. Therefore one of the Socialist leaders wrote: "Those who wish to understand Socialism will be wise to study Socialist books and papers. One does not expect a true and fair account of any theory or cause from its enemies. The man who takes his ideas of Trade-Unionism from the Free Labour League, his ideas of Liberalism from the Tory papers, his ideas of South African affairs--or any other affairs--from the Yellow Press, will be misled into all manner of absurdities and errors. The statements of party politicians and party newspapers on most controversial subjects are prejudiced and inaccurate; but there is no subject upon which the professional misleaders of the people are so untrustworthy and so disingenuous as they are upon the subject of Socialism."[26] A leading Socialist organ complained: "Our opponents decline to deal with the fundamental principles of Socialism--its unanswerable indictment of the capitalist system, with all its concomitants of wage-slavery and slumdom; prostitution and child murder--and prefer instead to indulge in calumniation and misrepresentation of Socialism. We need not complain about that. It is a tribute to the soundness of the Socialist position, to the irrefutability of its principles, the impregnability of the rock of economic truth upon which it is based, that our enemies dare not oppose the principles of Socialism, dare not attempt to meet the charge Socialism levels against the existing order."[27] There is much truth in these complaints. The general public and most writers and speakers know very little about Socialism, because this most interesting subject has been very inadequately treated in the existing books. The existing books on Socialism describe, analyse, and criticise the Socialist doctrines only in the abstract as a rule. However, Socialism is not only an elaborate economic doctrine, it is at the same time a complete system of practical politics. Hence it does not suffice to study the doctrines of Socialism by themselves. In order to understand Socialism we must also investigate its practical proposals.
