Abstract
This research seeks to reinterpret the theories of Waltz, Doyle, and Cox while pointing out the consequences of the concept of causation and its use by these authors. This ontological category has been understood following Hume’s philosophy, which has caused limitations and theoretical difficulties, also expressed in the fourth debate. We will turn to Milja Kurki’s causal pluralism based on critical realism and Aristotle to overcome this obstacle. This causal model makes it possible to reinterpret these three internationalist theories and thus integrate them coherently and systematically under the causal pluralist model.
