"At the London congress I renewed acquaintance with Rosa Luxemburg, whom I had known since 1904. She was a little woman, frail, and even sickly looking, but with a noble face, and beautiful eyes that radiated intelligence; she captivated one by the sheer courage of her mind and character. Her style, which was at once precise, intense and merciless, will always be the mirror of her heroic spirit. Hers was a many-sided nature, rich in subtle shadings. Revolution and its passions, man and art, nature, birds and growing things all these could play on the many strings of her soul. “I must have somebody,” she wrote to Luise Kautsky, “who believes me when I say that it is only through misunderstanding that I am in the midst of this whirlpool of world history, whereas in reality I was born to look after the geese in the fields.” My relations with Rosa were not marked by any personal friendship; our meetings were too brief and too infrequent. I admired her from a distance. And yet, I probably did not appreciate her enough at that time. On the question of the so-called permanent revolution, Rosa took the same stand as I did. In this connection, Lenin and I once had a half-humorous conversation in the lobby. The delegates stood about us in a close ring. “It is all because she does not speak Russian too well,” he said, referring to Rosa. “But then, she speaks excellent Marxian,” I retorted. The delegates laughed, and so did we."
