During the discussion of the relations between the political parties and the trade unions a heated argument took place between representatives of the I. W. W. (DeLeon faction) and of the Socialist party.[328] The Socialist party delegation made a long report in which the I. W. W. was referred to in no complimentary terms. F. W. Heslewood, representing the I. W. W.,[329] retorted that the report was "a tissue of lies and misrepresentations concerning the Industrial Workers of the World in America."[330] He went on to indicate the I. W. W. conceptions of the Socialist party of America in these terms:

This vote-catching machine of which the previous speaker from America (A. M. Simons) is so proud, will stoop to anything and go to any length to secure votes. They have defended a lot of scab unions of the A. F. of L. in California, have endorsed resolutions condemning the Japanese and asking for their exclusion from America, although we find that the Japanese, with very little education in revolutionary unionism, make better union men than the sacred contract scab of the A. F. of L.

At the other end of the continent, in New York, they place their candidates on the same ticket as Randolph Hearst, a Democrat, a trust-buster of the Roosevelt type. I have in my hand here a card ... asking the workers to vote for "Hearst and Hillquit." "Hearst and Hillquit" for good government? "Hearst and Hillquit" for socialism? No. "Hearst and Hillquit" for votes! Hillquit, the "revolutionist," one of the leading stars at this congress, the chief representative of this vote-catching machine: Hillquit, who has fed you on lies concerning the Industrial Workers of the World. If this is the way to get socialism, I hope that such a damnable brand will never be ushered in in my time. What bearing has this criminal work on our grand old slogan, "Workers of the world unite"?

In America we have two kinds of unions, one is known as the American Federation of Labor and the other is the Industrial Workers of the World. One has a million and a half members and the other has over 70,000 members including the Western Federation of Miners, that is 40,000 miners and 30,000 directly chartered members from the headquarters of the Industrial Workers. The larger one is called by the capitalist masters and their agents, "The bulwark of Capitalist Society," and the chiefs at the head of this scab arrangement were classed by Mark Hanna as his "able lieutenants," and that is what they are.[331]

DeLeon and Heslewood endeavored to put through a resolution in condemnation of the general position of neutrality taken by Socialist parties in their relation with labor organizations. They believed that a Socialist party should definitely endorse radical or socialistic trade unions and officially frown upon all reactionary unions, and especially condemn and discourage reaction wherever it might appear among labor organizations. "Neutrality towards trade unions," reads their resolution, "is equivalent to neutrality toward the machinations of the capitalist class."[332]

The resolutions on this subject which were finally adopted by the congress were much less militant in tone than the I. W. W. statement. The prevailing resolution read in part as follows:

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]
