Erkenntnis und Interesse

Jürgen Habermas

**Knowledge and Human Interests** (German: *Erkenntnis und Interesse*) is a 1968 book by the German philosopher Jürgen Habermas, in which the author discusses the development of the modern natural and human sciences. He criticizes Sigmund Freud, arguing that psychoanalysis is a branch of the humanities rather than a science, and provides a critique of the philosopher Friedrich Nietzsche. Habermas's first major systematic work, *Knowledge and Human Interests* has been compared to the philosopher Paul Ricœur’s *Freud and Philosophy* (1965). It received positive reviews, which identified it as forming part of an important body of work. However, critics have found Habermas's attempt to discuss the relationship between knowledge and human interests unsatisfactory, and his work obscure in style. Some commentators have found his discussion of Freud valuable, while others have questioned his conclusions. (Source: [Wikipedia](https://en.wikipedia.org/wiki/Knowledge_and_Human_Interests))
