Full Idea
The 'I' (which is not the same thing as the unitary government of our being!) is, after all, only a conceptual synthesis - thus there is no acting from 'egoism'.

A Reaction
Compare Sartre in Idea 7116. Since I am inclined to define the self as the controller of the brain, I am intrigued by the remark in brackets. Presumably he considers the self to be a fiction, and that animals don't have one. I think, probably, animals do.
