Gist of Idea
Maybe your emotions arise from you motivations, rather than being their cause

[He says this move is made by Kant, Thomas Nagel and McDowell] Stout favours the view that it is external facts which mainly give rise to actions, and presumably these facts are intrinsically motivating, prior to any emotions. I don't disagree.
