"Alexander Bain was probably the first modern thinker whose primary concern was with psychology itself He has been credited with writing the first 'comprehensive treatise having psychology as its sole purpose'. His two-volume systematic work, The Senses and the Intellect and The Emotions and the Will , was the standard British text for almost half a century, until Stout's replaced it. He also founded Mind , the first psychological journal in any country. His work requires close attention, because it is the meeting-point of experimental sensory-motor physiology and the association psychology. His influence on the conceptions of later workers was direct and extremely important. Ferrier studied classics and philosophy under Bain at Aberdeen . When he and Jackson acknowledge their intellectual debts or make references to psychology, the names most often mentioned are Bain and Spencer-the figures whose work was the culmination of the association psychology in its traditional form."
