for the relatively slow growth of the French labor movement as a whole. Workers who joined the syndicalist movement, he claims, were on the whole indifferent to doctrinal questions, their membership in syndicalist organizations was partly accidental and leaders were unable to convert workers to syndicalist ideas. Frederick Ridley, a political scientist, is more equivocal. According to him, leaders were very influential in the drafting of syndicalist ideas, but syndicalism was more than a mere tool of a few leaders, but a genuine product of the French labor movement. Darlington adds that in the Irish ITGWU most members were won over by the union's philosophy of direct action. Bert Altena argues that, though evidence of ordinary workers' convictions is scant, it indicates that they were aware of doctrinal differences between various currents in the labor movement and able to defend their own views. He points out that they likely understood syndicalist newspapers and debated political issues. Syndicalism is used by some interchangeably with anarcho-syndicalism. This term was first used in 1907, by socialists criticizing the political neutrality of the CGT, although it was rarely used until the early 1920s when communists used it disparagingly. Only from 1922 was it used by self-avowed anarcho-syndicalists. Syndicalism has traditionally been seen as a current within anarchism, but in some countries it was dominated by Marxists rather than anarchists. This was the case in Italy and much of the Anglophone world, including Ireland where anarchists had no significant influence on syndicalism. The extent to which syndicalist doctrine was a product of anarchism is debated. The anarchist Iain McKay argues that syndicalism is but a new name for ideas and tactics developed by Bakunin and the anarchist wing of the First International, while it is wholly inconsistent with positions Marx and Engels took. According to him, the fact that many Marxists embraced syndicalism merely indicates that they abandoned Marx's views and converted to Bakunin's. Altena too views syndicalism as part of the broader anarchist movement, but concedes there was a tension between this and the fact that it was also a labor movement. He also sees Marxist ideas reflected in the movement, as leading syndicalists such as F. Domela Nieuwenhuis and Christiaan Cornelissen as well as much of the Australian syndicalist movement were influenced by them, as well as older socialist notions. According to Darlington, anarchism, Marxism, and revolutionary trade unionism equally contributed to syndicalism,
