Failure of the Communist International to spread revolutions outside of Russia was attributed to its "subjective revolutionary ideas," by Dr. Merle Fainsod, instructor in Government, in the fourth of his series of six lectures yesterday, in which he discussed the history of that organization in the period following the revolution.

In commenting upon this failure of the Communists to secure any general rebellious enthusiasm, he declared that the success of any revolutionary group must be measured in terms of the revolutions which are brought about as a result of its efforts.

He went on to say that members "fell victims . . . to a false professional optimism." They idealized the workers, he said, without realizing that the revolutionary doctrines which appealed to themselves might not be those most compelling to the workers. When that failed, he said, they concentrated their attack on what they termed the "mis-leaders" of the workers; namely, the Social-Democrats.

Dr. Fainsod announced that in the next lecture he will discuss the "exciting" history and activities of the Communist International in China.
