“Even I found some things rather objectionable when I read Rosa Luxemburg's book [Introduction to Economics], but, given the sort of person I am, the experience on the whole was one of profound interest. The subject matter of her book is generally considered to be economics, but if it is read as economics, it is boring beyond belief. It contains nothing but exceedingly obvious platitudes. It may be, of course, that I have no understanding of economics. Be that as it may, the subject holds not the slightest interest for me. A science which is postulated on the assumption that human beings are avaricious and will remain avaricious through all eternity is utterly devoid of point (whether in problems of distribution or any other aspect) to a person who is not avaricious. And yet as I read this book, I felt a strange excitement for quite another reason the sheer courage the author demonstrated in tearing apart without any hesitation all manner of conventional ideas.”
