Brentano on the Impact of Psychology on Philosophy Johannes L. Brandl (Uni Salzburg, Uni Fribourg) *recommends speaking to Martine Nida-Rummelin
B's mission: radical turnaround in phil. by providing help from psychology
- In current Phil Brentanian themes
- inner C
How to get back to B's mission? His claims: • Psych is important • Phil progress depends on psych progress Two kinds of psych: • Descriptive (beschreibende Psychologie) Describe the basic components of perception (introspective) • Genetic Explores conditions for experiences (empirical)
Brandl: thinks B’s motive was to bridge naturalistic sciences and descriptive psych -”humanities on one side, psych on the other”
Problem with D-psych: new ontological objects - some precedent: Mill -”first step of inductive inquiry is a mental analysis of complex phenomena”
Opposing views: Ewald Hering, Hermann Lotze, Wilhelm Dilthey
Psychologism was meant by B to be a foundation of knowledge.
Modal thesis: descriptive psych is an “exact science” revealing necessary (apodictic) truths about the mind - Judg are pos or neg Feelings are of - Feeling presupposes judg
Objections: Inner perception not indefeasible evid. Does not reveal necessary features of mental states that can be generalized by “a priori induction”
Grand Illusion: Phil is is an a priori discipline founded on a basis of necessary (apodictic) truths D-psych can provide these truths
B claims that knowledge is judg in defense.
Rationalistic “Unexpected Alliance” Leibniz- characteristica universalis Frege- begriffschrift Brentano- d-psych
Criticism: Phil progress not necessarily in line with progress in logic, psych, etc.
Back to beginning: psych and Phil still artificially divided (p7, Psych from Emp. Standpoint)
Brandl- image was that psych could be a bridging discipline from natural sciences, physiology, to philosophy
Current situation (Neuroscience (.) Psychology (.) Phil of mind (.) other Phil- ethics, etc.)
B was wrong- no scientific discipline restricts itself to phenom in C No self-evident psych knowledge (because psych concepts are theory-laden)
B was right- intentionality and inner C are indispensable concepts in Phil of mind Interpretation of these concepts is crucial for bridging gap between psych and Phil
Brandl - gap between psych and Phil is growing
