Preface to the Revised Translation, 1939

The mental picture which the thinker forms to represent the concept in an individual way (“Vorstellung”) is here called a “representation.” This word, however clumsy it may seem at the first glance, is justified, because the mental picture indeed stands for the concept and represents it Coleridge has used the term representation in this sense. Recent writers on psychology have adopted it with the obvious aim of avoiding confusion.
