The article investigates the distinction between the physical and the intentional causality that appeared in the 17thcentury scholasticism in the course of polemics with the traditional Aristotelian classification of causes and with the conception of causality developed by Francisco Suárez. The introduction of the distinction between physical and intentional causation was motivated by the insufficiency of the notion of causality, adopted in ancient and medieval natural philosophy to describe the causal processes in the sphere of conscious human activity.
