In his sweeping account of humanity's social and political development, the author develops a theory of human evolution that prefigures Darwinian thought and encompasses aspects of ethics, sociology, and epistemology. He concludes that people are inevitably corrupt as a result of both natural (or physical) inequalities and moral (or political) inequalities.One of the most influential works of the Enlightenment, the Discourse on the Origin of Inequality offers a thought-provoking account of society's origins and a keen criticism of unequal modern political institutions.

    Take any book of apologetics-that is to say, of theological advocacy-and you will see how many times you will meet with this phrase-"the disastrous consequences of this doctrine." Now the disastrous consequences of a doctrine prove at most that the doctrine is disastrous, but not that it is false, for there is no proof that the true is necessarily that which suits us best. -from "The Rationalist Dissolution" This is the masterpiece of Miguel de Unamuno, a member of the group of Spanish intellectuals and philosophers known as the "Generation of '98," and a writer whose work dramatically influenced a wide range of 20th-century literature. His down-to-earth demeanor and no-nonsense outlook makes this 1921 book a favorite of intellectuals to this day, a practical, sensible discussion of the war between faith and reason that consumed the twentieth century and continues to rage in the twenty-first century. de Unamuno's philosophy is not the stuff of a rarefied realm but an integral part of fleshly, sensual life, metaphysics that speaks to daily living and the real world. Spanish philosopher MIGUEL DE UNAMUNO (1864-1936) was a prolific writer of essays, novels, poetry, and the stage plays. His books include Peace in War (1895), The Life of Don Quixote and Sancho (1905), and Abel Sanchez (1917)."

    The stock market is certainly rational; one can understand it, study it, capitalists know how to use it, and yet it is completely delirious, it is mad. That's why we say: the rational always is the rationality of an irrational. Marx is fascinated by capitalist mechanisms precisely because the system is demented, yet works very well at the same time. Down below, there are investments of desire that cannot be confused with the investments of interest: all kinds of libidinous-unconscious flows that make up the delirium of this society. The true history is the history of desire."This collection of essays and interviews edited by Sylvere Lotringer and published in 1995, focuses on the French anti-psychiatrist and theorist's work as director of the experimental La Borde clinic ("A Clinic Unlike Any Other") and longtime collaborator with the philosopher Gilles Deleuze."Chaosophy" is a groundbreaking introduction to Guattari's theories on "schizo-analysis" a process meant to replace Freudian interpretation with a more pragmatic, experimental, and collective approach rooted in reality. Unlike Freud, Guattari believes that schizophrenia is an extreme mental state induced by the capitalist system itself, which keeps enforcing neurosis as a way of maintaining normality. Guattari's post-Marxist vision of capitalism provides a new definition not only of mental illness, but also of the micropolitical means of its subversion.This collection contains key essays, such as, "Balance-Sheet Program for Desiring-Machines" and "Capitalism and Schizophrenia," co-signed by Deleuze (with whom he co-authored "Anti-Oedipus" and "A Thousand Plateaus"), and the perennially provocative "Everybody Wants To Be a Fascist.
