Franz Brentano's classic study Psychology from an Empirical Standpoint was the most important of Brentano's works to be published in his lifetime. Unlike the first English translation in 1974, this edition simply contains the text corresponding to Brentano's original 1874 edition. A new introduction by Peter Simons places Brentano's work in the context of current philosophical thought, and is able to show how Brentano has emerged since the Seventies as a key figure in both contemporary European and Anglo-American traditions and crucial to any understanding the history of philosophy and psychology.
