Alexander Bain

"Instinct is untaught ability."

"Disinterestedness is as great a puzzle and paradox as ever. Indeed, strictly speaking, it is a species of irrationality, or insanity, as regards the individual’s self; a contradiction of the most essential nature of a sentient being, which is to move to pleasure and from pain"

"The arguments for the two substances - mind and body - have, we believe, entirely lost their validity; they are no longer compatible with ascertained science and clear thinking. One substance with two sets of attributes, two sides (a physical and a mental), a double-faced unity, would appear to comply with all the exigencies of the case."

"What renders a problem definite, and what leaves it indefinite, may best be understood from mathematics. The very important idea of solving a problem within limits of error is an element of rational culture, coming from the same source. The art of totalizing fluctuations by curves is capable of being carried, in conception, far beyond the mathematical domain, 65 where it is first learned. The distinction between laws and coefficients applies in every department of causation. The theory of Probable Evidence is the mathematical contribution to Logic, and is of paramount importance."

"Those that can readily master the difficulties of Mathematics find a considerable charm in the study, sometimes amounting to fascination. This is far from universal; but the subject contains elements of strong interest of a kind that constitutes the pleasures of knowledge. The marvellous devices for solving problems elate the mind with the feeling of intellectual power; and the innumerable constructions of the science leave us lost in wonder."

"The method of arithmetical teaching]] is perhaps the best understood of any of the methods concerned with elementary studies."

"He that could teach mathematics well, would not be a bad teacher in any of the rest [physics, chemistry, biology, psychology] unless by the accident of total inaptitude for experimental illustration; while the mere experimentalist is likely to fall into the error of missing the essential condition of science as reasoned truth; not to speak of the danger of making the instruction an affair of sensation, glitter, or pyrotechnic show."

"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 (1855) and The Emotions and the Will (1859), was the standard British text for almost half a century, until Stout's replaced it. He also founded Mind (1876-), 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 (first class honours, 1863). 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."
