Full Idea
The analysis of causation in terms of dispositions provides no conceptual reduction, but it does provide insight into the metaphysics of causation. We then know what causation is - it is the stimulation and manifestation of a disposition.
Gist of Idea
The dispositional account explains causation, as stimulation and manifestation of dispositions

A Reaction
I would say that it offers the essence of causation, by giving a basic explanation of it. See Mumford/Lill Anjum on this.
