Wilhelm Wundt

"The results of ethnic psychology constitute... our chief source of information regarding the general psychology of the complex mental processes."

"In Aristotle the mind, regarded as the principle of life, divides into nutrition, sensation, and faculty of thought, corresponding to the inner most important stages in the succession of vital phenomena."

"From the standpoint of observation, then, we must regard it as a highly probable hypothesis that the beginnings of the mental life date from as far back as the beginnings of life at large."

"We call that psychical process, which is operative in the clear perception of a narrow region of the content of consciousness, attention."

"The whole task of psychology can therefore be summed up in these two problems : (1) What are the elements of consciousness ? (2) What combinations do these elements undergo and what laws govern these combinations ?"

"If we take an unprejudiced view of the processes of consciousness, free from all the so-called association rules and theories, we see at once that an idea is no more an even relatively constant thing than is a feeling or emotion or volitional process. There exist only changing and transient ideational processes ; there are no permanent ideas that return again and disappear again."

"He aims at being a sort of Napoleon of the intellectual world. Unfortunately he will never have a Waterloo, for he is a Napoleon without genius and with no central idea which, if defeated, brings down the whole fabric in ruin."

"Throughout the nineteenth century, apart from the division in theoretical sciences and arts, classifiers attempted to divide the sciences into two groups. Already they had before them the examples of Francis Bacon (speculative and descriptive) and Hobbes (quantitative and qualitative). For Coleridge, the sciences were either pure (Grammar, Logic, Rhetoric, Mathematics, Metaphysics) or mixed. Arthur Schopenhauer’s similar groups were called pure and empirical, Wilhelm Wundt in 1887 called them formal and empirical, Globot mathematical and theoretical, and the St. Louis Congress of Arts and Sciences (1904) normative and physical. made similar division of the sciences into abstract and concrete"

"Imagery played a central role in theories of the mind for centuries. For example, the British Associationists conceptualizes thought itself as sequences of images. And, Wilhelm Wundt, the founder of scientific psychology, emphasized the analysis of images. However, the central role of imagery in theories of mental activity was undermined when Kulpe, in 1904, pointed out that some thoughts are not accompanied by imagery (e.g., one is not aware of the processes that allow one to decide which of two objects is heavier)."
