After that time the works of Karl Marx and Frederick Engels, especially the influential Communist Manifesto (1848), enjoyed an international audience. The world was to learn a new political vocabulary peppered with "socialism", "capitalism", "the working class", "the bourgeoisie", "labour theory of value", "alienation", "economic determinism", "dialectical materialism", and "historical materialism". Marx's economic analysis of history has been a powerful legacy, the effects of which continue to be felt world-wide.Serving as the foundation for Marx's indictment of capitalism is his extraordinary work titled "Economic and Philosophic Manuscripts", written in 1844 but published nearly a century later. Here Marx offers his theory of human nature and an analysis of emerging capitalism's degenerative impact on man's sense of self and his creative potential. What is man's true nature? How did capitalism gain such a foothold on Western society? What is alienation and how does it threaten to undermine the proletariat? These and other vital questions are addressed as the youthful Marx sets forth his first detailed assessment of the human condition.

    The work also constitutes an enduring critique of liberalism and socialism from the perspective of an extreme eccentric individualism. Stirner has latterly been portrayed variously as a precursor of Nietzsche, a forerunner of existentialism, an individualist anarchist, and as manifestly insane. This edition includes an Introduction placing Stirner in his historical context.

    He was seen as a champion of individualism and a prescient critic of the countervailing pressures of society, and he disseminated his thoughts through dozens of published essays and more than 1,500 public lectures across the United States. Emerson gradually moved away from the religious and social beliefs of his contemporaries, formulating and expressing the philosophy of transcendentalism in his 1836 essay "Nature." Following this work, he gave a speech entitled "The American Scholar" in 1837, which Oliver Wendell Holmes Sr. considered to be America's "intellectual Declaration of Independence." Emerson wrote most of his important essays as lectures first and then revised them for print. His first two collections of essays, Essays: First Series (1841) and Essays: Second Series (1844), represent the core of his thinking. They include the well-known essays "Self-Reliance," "The Over-Soul," "Circles," "The Poet" and "Experience." Together with "Nature," these essays made the decade from the mid-1830s to the mid-1840s Emerson's most fertile period. Emerson wrote on a number of subjects, never espousing fixed philosophical tenets, but developing certain ideas such as individuality, freedom, the ability for humankind to realize almost anything, and the relationship between the soul and the surrounding world. Emerson's "nature" was more philosophical than naturalistic: "Philosophically considered, the universe is composed of Nature and the Soul." Emerson is one of several figures who "took a more pantheist or pandeist approach by rejecting views of God as separate from the world."
