To enfranchise the proletariat completely from the bonds of intellectual, political and economic serfdom, the political and the economic struggle are alike necessary. If the activity of the Socialist party is exercised more particularly in the domain of the political struggle of the proletariat, that of the unions displays itself in the domain of the economic struggle of the workers. The unions and the party have therefore an equally important task to perform in the struggle for proletarian emancipation. Each of the two organizations has its distinct domain defined by its nature, and within whose borders it should enjoy independent control of its line of action. But there is an ever-widening domain in the proletarian struggle of the classes in which they can only reap advantages by concerted action and by coöperation between the party and the trade unions.[333] Further along in the same resolution the Congress declared that the unions could not fully perform their duty in the struggle for the emancipation of the workers unless "a thoroughly socialist spirit inspires their policy" and that it was the duty of the party and the unions to render each other "moral support."[334] The editor of the official organ, however, looked upon these resolutions as being very favorable to the I. W. W., which he declared had forced the Congress to "a recognition of the paramount importance of the economic organization, with the result that the Congress itself stands almost on I. W. W. ground."[335] The 1907 convention was a gathering of the DeLeon-Trautmann-St. John faction. At the fourth convention the first hyphen was to be smashed, but in 1907 both links held firmly. The general tone was one of harmony. An attempt was made, however, to reëstablish the office of President. After a long debate on a resolution to this effect the proposition was defeated. It was decided, however, to establish the office of General Organizer, the incumbent of which was expected also to act as Assistant General Secretary. The original preamble of 1905 had weathered the second convention without being modified. The first lines of the second paragraph read: "Between these two classes a struggle must go on until all the toilers come together _on the political_ as well as on the industrial field...." A motion was made at the third convention to strike out the words italicized. It was defeated by vote of 113 to 15.[336]
