Lecture V

Starting from these premises Brentano did his utmost to find solutions to the two greatest riddles of the human soul, the riddle of truth, and the riddle of good. What is true (or real)? What is good? If one is seeking to justify the judgment of thinking about reality or unreality, the question arises, Why do we acknowledge certain things and reject others? Those we acknowledge we regard as truth; those we reject we regard as untruth. And that brings us straight to the heart of the problem: What is truth? The heart of the other problem concerning good and evil, good and bad, we encounter when we turn to the realm of fluctuating moods and feelings. According to Brentano, love is what prompts us to acknowledge an action as good, while hate is the rejection of an action as evil. Thus ethics, morality, and what we understand by rights, all these things are a province of the realm of moods and feelings. The question of good and evil was very much in Brentano's mind as he pondered the nature of man's life of feelings fluctuating between love and hate.
