Editorial note — Page 18 CHAPTER II

[Footnote 1: The clearest statement of the status of instincts as both mechanisms of action and "drives" to action has been made by Professor Woodworth in his Dynamic Psychology. No one else, to the best of the author's knowledge, has made the distinction with the same clarity and emphasis, though it has been suggested in the work of Thorndike and McDougall. In McDougall's definition of an instinct he recognizes both the responsive self and the tendency to make the response. An instinct is, for him, an inherited disposition which determines its possessor, in respect to any object, "to act in regard to it in a particular manner, or at least to experience an impulse to such action."]
