“Is it this simple to influence the world. If any ambitious man have a fancy to revolutionize at one effort the universal world of human thought, human opinion, and human sentiment, the opportunity is his own — the road to immortal renown lies straight, open, and unencumbered before him. All that he has to do is to write and publish a very little book. Its title should be simple — a few plain words — "My Heart Laid Bare." But — this little book must be true to its title.” ~ Edgar Allan Poe in 1844.
I disagree with Edgar Allan Poe. It is not simple to influence the world. A book can influence the word only if it appears at the right place, at the right time, and is discovered by the right kind of politicians. Marx could become the great revolutionary philosopher of the twentieth century because politicians like Lenin and Trotsky realized that they could use Marxism to overthrow the regime of Emperor Nikolai II Alexandrovich Romanov. The success of Lenin and Trotsky in overthrowing the Russian monarchy turned Marxism into the most lethal political weapon of the twentieth century.
Every Marx needs men like Lenin and Trotsky for influencing the destiny of the world.
