I'm not sure how best to articulate this, but it seems to me like modern cognitive science actually does not really have much to add to this conversation that we don't already know.

For example, I'm not sure that it's particularly revealing or unexpected that modern cognitive science would support a dependent relationship between emotion and reason.

For instance, upon learning that Biden dropped out of the election, one's emotional reaction to that news is going to depend entirely on various facts, beliefs, and predictive (i.e. rational) models they have adopted over the years.

The vast majority of emotional responses in our daily life might be described as manifestations of the "anticipatory" (i.e. "predictive") emotions of fear or hope, which represent kind of a "meta" manifestation of the broader relationship I've described of goal setting, strategizing, and evaluating - in which our emotions inform the first and last steps, with rationality forming the strategic middle.

So it would make sense that cognitive science would affirm a tight relationship between rationality and emotion.

But I think it nevertheless still makes sense for our model to think of rationality and emotion as separate concepts, having a relationship very similar to what I described, where emotion forms the motivations and goals, while accurate, rational predictions form the strategy.
