Ludwig Feuerbach

Ludwig Andreas Feuerbach (; ; 28 July 1804 – 13 September 1872) was a German philosopher and anthropologist who was a leading figure among the Young Hegelians. He is best known for his 1841 book, ''The Essence of Christianity'', which argued that God is a projection of the essential attributes of humanity. His critique of religion formed the basis for his advocacy of atheism, materialism, and sensualism. In his later work, Feuerbach developed a more complex theory of religion arising from the human confrontation with nature. His thought served as a critical bridge between the philosophy of Georg Wilhelm Friedrich Hegel and that of Karl Marx.

The son of a distinguished jurist, Feuerbach studied theology at Heidelberg before moving to Berlin to study directly under Hegel. His academic career was cut short in 1830 when his anonymously published first book, ''Thoughts on Death and Immortality'', was condemned as scandalous for its attack on the concept of personal immortality. Barred from university posts, Feuerbach lived in rural isolation for much of his life, supported by his wife's share in a porcelain factory, where he produced most of his significant writings.

Feuerbach's philosophy developed as a critique of Hegel's speculative idealism, which he viewed as the last, most abstract form of theology. He argued that idealism inverted the true relationship between thought and being, and that philosophy's proper subject was not the abstract Absolute, but the concrete, sensuous human being. In ''The Essence of Christianity'', he contended that religion is a form of self-alienation in which humanity projects its own "species-essence"—its unlimited capacity for reason, love, and will—onto a divine being, which it then worships. In his later works, including the ''Lectures on the Essence of Religion'', he developed a "bipolar" theory of religion in which religious belief arises from the human confrontation with nature, driven by the "drive to happiness" and the fear of death.

Feuerbach's thought was a major influence on his contemporaries, particularly Marx and Friedrich Engels. Marx adopted Feuerbach's materialist inversion of Hegel and his theory of alienation, but later criticized him in his ''Theses on Feuerbach'' for having a materialism that was too contemplative and for understanding humanity in terms of a static "essence" rather than in terms of concrete social and historical practice (''praxis''). Feuerbach's work also exerted an influence on the thought of Friedrich Nietzsche and Sigmund Freud. Provided by Wikipedia
