Der Begriff des Instinktes einst und jetzt (English: The concept of instinct in past and present times) is a book written by Heinrich Ernst Ziegler. Its first edition was published in the Zoologische Jahrbücher, Supplement VII (English: Zoological yearbooks) in 1904. The second edition, published 1910 by Gustav Fisher in Jena and third edition, published in 1920 under the same publisher both received several extensions. The book is about the history of the concept instinct and the different conceptions of the animal psyche throughout history, as well as the understanding of these concepts at the time the book was published. Furthermore, it discusses the implications of Charles Darwin's theory of common descent for comparative psychology.^[1]
