Abstract
The paper discusses critically the evolution of Lipps's view on logic and psychology. According to Lipps, psychology is the fundamental science on which the other sciences are grounded, and "logic is a special discipline of psychology". Husserl criticizes such conception, which falls into a confusion of domains, and proposes the idea of a pure logic on the basis of the distinction between ideal and real. Lipps replies to Husserl maintaining that the overcoming of psychologism requires both a sharp separation of object and content and a distinction of the different meanings of psychology. The latter is, according to Lipps, not an empirical science, but the science of the self, pure psychology, i.e., something like Aristotle's first philosophy; as such, psychology is the ground of logic: the laws of logic are valid both for thought and for objects, but they are facts of consciousness and hence they belong to psychology. Finally, an evaluation is given of various interpretations of Lipps's attempts to overcome psychologism.
