Editing Wilhelm Wundt (section)

===The delineation of categories===

Wundt considered that reference to the subject (Subjektbezug), value assessment (Wertbestimmung), the existence of [[Intention|purpose]] (Zwecksetzung), and volitional acts (Willenstätigkeit) to be specific and fundamental categories for psychology.<ref>Wundt: Ueber psychische Causalität und das Princip des psycho-physischen Parallelismus, 1894</ref> He frequently used the formulation "the human as a motivated and thinking subject"<ref>Wundt: Logik. 1921, Band 3, S. 15–19.</ref> in order to characterise features held in common with the [[humanities]] and the categorical difference to the [[natural sciences]].<ref>Fahrenberg: Zur Kategorienlehre der Psychologie, 2013, S. 86–131.</ref>
