MORAL PHILOSOPHY OF FRANZ BRENTANO
Brentano has divided mental phenomena into three main groups: presentations (ideas), judgements and emotions. Both judgements and emotions involve presentations as its foundation. Each judgement consists in acceptance or rejection of an object of some presentation; and each act of emotion consists in love or hate directed upon such presented object.
Both for judgements and for emotional phenomena Brentano formulates the theory of its correctness. The judgement is correct if the same judgement would be made also by somebody who judges with evidence. As there is, according to Brentano, the analogue of evidence for the emotional phenomena, their correctness may be defined analogically.
In terms of so understood correctness of mental acts defines Brentano both truth and good. Consequently, his theory needs neither objective states of affairs nor objectively interpreted values.
In the last paragraphs, we discuss an interesting problem, how Brentano, who was always a strict determinist, solves the question of freedom, that is central for ethics.
