Such, in brief outline, is the history of the man Trotzky. It is a typical Russian history: the story of a persistent, courageous, and exceedingly able fighter for an ideal believed in with fanatical devotion. Lenine, in one of his many disputes with Trotzky, called him "a man who blinds himself with revolutionary phrases,"[17] and the description is very apt. He possesses all the usual characteristics of the revolutionary Jewish Socialists of Russia. To a high-strung, passionate, nervous temperament and an exceedingly active imagination he unites a keen intellect which finds its highest satisfaction in theoretical abstractions and subtleties, and which accepts, phrases as though they were realities. Understanding of Trotzky's attitude during the recent revolutionary and counter-revolutionary struggles is made easier by understanding the development of his thought in the First Revolution, 1905-06. He began as an extremely orthodox Marxist, and believed that any attempt to establish a Socialist order in Russia until a more or less protracted intensive economic development, exhausting the possibilities of capitalism, made change inevitable, must fail. He accepted the view that a powerful capitalist class must be developed and perform its indispensable historical role, to be challenged and overthrown in its turn by the proletariat. That was the essence of his pure and unadulterated faith. To it he clung with all the tenacity of his nature, deriding as "Utopians" and "dreamers" the peasant Socialists who refused to accept the Marxian theory of Socialism as the product of historic necessity as applicable to Russia.
