Psychologism

It is not a linear and one-dimensional process, but is characterised by having different origins, motivations, and aspects with a relative degree of autonomy and different stages in each of them.

There was no single Psychologismusstreit process, but a multiplicity of simultaneous and successive controversies, that even though they had thematic and temporal links, were either factually unconnected or only indirectly related.

The Psychologismusstreit did not exist as a thetic-thematic unit with previously defined contenders, but rather the demarcation line between psychologism and anti-psychologism was permanently reformulated so that positions considered anti-psychologism in one period, become considered psychologism in another. If at first it is enough to accept the distinction act – content or the normative nature of logical laws (Herbart, 1816 [1882]: 127), after consideration, only one who accepts Platonism in some way (Bolzano, 1837: 76ff.; Lotze, 1874 [1912]: 505f.), or only one who denies the immanence principle (Frege, 1893: XIXf.), or only one who does the transcendental reduction (Husserl, 1925 [1962]: 287ff.; 1927–31 [1962]: 344ff.) is an anti-psychologist thinker.
