One sign of the multidimensionality of Rosa Luxemburg's life and work is the way she appeals to thinkers and activists coming from a number of different directions. Some view her primarily as a brilliant economist, who wrote the first study (at least since Marx's Capital) of capitalism's inherent drive for global expansion. Others view her mainly as a path-breaking political thinker, because of her embrace of spontaneous forms of revolt and her searing critique of those who fail to grasp the centrality of mass participation and democracy in efforts at social revolution. Others are drawn to her largely because of her striking personality, which exhibited a fiercely independent spirit and a fascination with both the beauty and tragedy of the human and natural world. The great merit of Jacqueline Rose's review of The Letters of Rosa Luxemburg is that it focuses on what connects the many strands of Luxemburg's legacy—her profound appreciation of the transformative power of the human intellect.
