In the selection of documents the editor has aimed to choose as far as possible those of the greatest political and economic importance. No material has been omitted or included merely because it seemed creditable or dis creditable to Socialists in general or to the Socialists of any particular country. I have not tried to explain away any of their acts or failures to act, nor on the other hand have I endeavored to pass any final judgment. I have merely undertaken to offer in a condensed and connected form all the materials necessary to reach an opinion on any of the leading phases of this great ques tion: the attitude of the Socialists of all countries towards war and peace, and especially towards the present war and the peace that is to follow.
