Francois Laruelle proposes a theory of identity rooted in scientific notions of symmetry and chaos, emancipating thought from the philosophical paradigm of Being and reconnecting it with the real world. Unlike most contemporary philosophers, Laruelle does not believe language, history, and the world shape identity but that identity determines our relation to these phenomena. Both critical and constructivist, Theory of Identities finds fault with contemporary philosophy's reductive relation to science and its attachment to notions of singularity, difference, and multiplicity, which extends this crude approach. Laruelle's new theory of science, its objects, and philosophy, introduces an original vocabulary to elaborate the concepts of determination, fractality, and artificial philosophy, among other ideas, grounded in an understanding of the renewal of identity. Laruelle's work repairs the rift between philosophical and scientific inquiry and rehabilitates the concept of identity that continental philosophers have widely criticized. His argument positions him clearly against Deleuze, Badiou, the new materialists, and other thinkers who stray too far from empirical approaches that might revitalize philosophy's practical applications.

In Science Fiction and Extro-Science Fiction, Quentin Meillassoux addresses the problem of chaos and of the constancy of natural laws in the context of literature. With his usual argumentative rigor, he elucidates the distinction between science fiction, a genre in which science remains possible in spite of all the upheavals that may attend the world in which the tale takes place, and fiction outside-science, the literary concept he fashions in this book, a fiction in which science becomes impossible. With its investigations of the philosophies of Hume, Kant, and Popper, Science Fiction and Extro-Science Fiction broadens the inquiry that Meillassoux began in After Finitude, thinking through the concrete possibilities and consequences of a chaotic world in which human beings can no longer resort to science to ground their existence. It is a significant milestone in the work of an emerging philosopher, which will appeal to readers of both philosophy and literature. The text is followed by Isaac Asimov's essay "The Billiard Ball."
