. His multivolume "Collected Works" make people think he was an intellectual. In fact, he was not: most of these papers are his orders, i.e. things hardly classifiable as "literary work"; he liked discussions only for the opportunity to humiliate his opponents; and he was the first of Russian revolutionaries who established relations with organized criminality. He was incapable of doing forecasts (two months before the revolution he said: "Only our grandsons will see socialism in russia") while possessing at the same time extremely great improvisational skills. He disliked intellectuals and used the whole wealth of Russian vocabulary to describe them
Russian typologists believe he was ESTP; and, in fact, many features really make him much similar to Peter the Great.
. I agree with you about his being TJ (all other American sources say the same); but let Me add some more information. The thing I cannot understand is how American typologists arrived at the belief in his extraversion. In fact, he was a model introvert! In spite of his enormous power, he was extremely shy and closed towards people he had to communicate with. Leon Trotsky Describes This Feature In a very Colorful Way; and what I know is that Trotsky's books are easy to find in the US, so that you can easily disprove or verify my words. He liked to present his own opinion as that generally accepted: he used to say, "there is an opinion" instead of "I think". He spoke rarely and thought a lot. His strategy was not extensive - he persuaded the party to forget about expanding revolution outside Russia and to think about the internal order of the country; Unlike Lenin, he did not believe that people outside Russia would gladly meet revolution in their own countries, and relied in this problem only upon weapons.
Another important thing is that he could not be intuitive. Even much more than Lenin he tended to practice more than to pure ideas. He used to say "we people of practice" opposed to "worthless idealists". In the Soviet era, he was glorified as a "great developer of Marxist theory"; in fact, he was incapable of abstract thinking. A good example - Lenin wrote him a memo with a proposal to make a forecast: Stalin was offended by that proposal, and replied "Do you think I am incapable of serious working, if you want Me to spend time for such worthless things?" He collected a big library of anti-Soviet literature, but read all books with a narrow practical objective: to detect enemy's weak points. Characteristic for his weak abstract thinking is his "friendship" with ****** - he did not want to realize ****** ' strive for expansion; he only noticed similarity of two regimes. He was suspicious to people around him and used to say "a man - a problem, no man - no problem".
