What Is Causation?

From the Thomas perspective, causation is real. When a baseball hits a window and the window breaks, should we say that the baseball is the cause and the broken window is the effect? That might sound obviously right, but actually there is an alternative. Some philosophers like to speak of event causality. This can be called agent causation as long as we are willing to use the word agent broadly. So as to include not just rational agents, but also non-rational agents like baseballs.
