Though Professor Wundt first won recognition through his investigations in physiology, it was his later and more valuable contributions to physiological psychology, as well as to logic, ethics, epistemology, and metaphysics, that gained for him his place of eminence in the world of scholarship. One may hazard the prophecy, however, that the final verdict of history will ascribe to his latest studies, those in folk psychology, a significance not inferior to that which is now generally conceded to the writings of his earlier years. The _Völkerpsychologie_ is a truly monumental work. The analysis and interpretation of language, art, mythology, and religion, and the criticisms of rival theories and points of view, which occupy its five large volumes of over three thousand pages, are at once so judicial and so suggestive that they may not be neglected by any serious student of the social mind. The publication of the _Völkerpsychologie_ made necessary a number of defensive and supplementary articles. Two of these, in a somewhat revised form, together with an early article on "The Aim and Methods of Folk Psychology," and an additional essay on "Pragmatic and Genetic Psychology of Religion," were published in 1911 under the title, _Probleme der Völkerpsychologie_. Finally, in 1912, there appeared the book which we are now presenting in translation, the _Elemente der Völkerpsychologie_. As regards the difference in method and character between the _Elemente_ and the _Völkerpsychologie_, nothing need be added to what may be gleaned from the author's Preface and Introduction to this, his latest, work. Here, too, Professor Wundt indicates his conception of the nature and the problem of folk psychology, a fuller discussion of which may be found both in the _Völkerpsychologie_ and in the first essay of the _Probleme_.
