Brain Mapping

Intentionality is to be understood in psychological(or in what might today be called methodologically solipsistic) terms. To say that a mental act is “directed toward an object” is to make an assertion about the interior structure or representational content of the act.

1. In presentation. Here the subject is conscious of the object or object-form, and has it before his mind, without taking up any position with regard to it, whether in sensory
experience or via concepts.

2. In judgment. Here there is added to presentation one of two diametrically opposed modes of relating cognitively to the object: modes of acceptance and rejection or of belief and disbelief. Perception, for Brentano, is a combination of sensory presentation and positive judgment.

3. In phenomena of interest. Here there is added to presentation one of two diametrically opposed modes of relating conatively to the object: modes of positive and negative interest or of “love” and “hate.” Judgment and interest are analogous in that there is a notion of correctness applying to each: the correctness of a judgment (its truth) serves as the objective basis of logic, the correctness
of love and hate as the objective basis of ethics.
