Note 9 — INTRODUCTION. THE EVOLUTION OF THE AFFECTIVE LIFE.
Reading edition
Höffding, Psychologie, pp. 392-394, second German edition. J. Sully, The Human Mind, vol. ii. p. 56, considers emotion as a genus of which affection and passion are the species: affection is a fixed emotional disposition; passion is the violent form of the emotion. Nothing can be vaguer and more uncertain than the terminology of our subject, and yet, as Wundt says in his Essays, it has made a very appreciable progress when compared to the confusion which existed at the beginning of the century.
