One might well be tempted to follow Myles Burnyeat, and see the young Brentano as treating the psychic causality in the De anima as identical to intentionality. As shown above, however, Brentano in his later writings does not maintain this interpretation, but finds in Aristotle a distinction between causality and intentionality. For Brentano, this distinction is based on Metaphysics Δ.15, where Aristotle assigns the causal connections and intentional connections between cognitive acts and their objects to two different classes of relation. Brentano adopts this distinction, and contrasts psychic "affection" (Leiden) and intentionality.
