This book was released in the 80's I believe. It is an english translation of many of Kristeva's most important and influential texts. Although definitely dense, in the sense that it is Kristeva's reflections on mostly Lacanian understandings of psychoanalytic theory, (everyone needs to make their own Lacan I sense), it has a lot of the juicy backbones of Lacan.
I think to read it directly through, is an arduous task. Yet, these collections of essays, which are pulled from several of her books and articles she has published, are really the spine of her thought and help to explain her understandings of: language, subjectivity, feminism, abjection, love and the political.
Each essay in itself, is something which could offer a seminal reading. And in the future, I will probably refer to it, when I am interested in seeing how Kristeva's reflections may help illuminate my own understanding of something.
Kristeva is awesome. That is all.
