The common shorthand in psychology circles for the tension between emotion and cognition--between what we feel and what we think--is to use the Star Trek characters of Captain Kirk and Officer Spock. Kirk is all heart, a man of intense and compelling emotions. He's fire. By contrast, Spock, that lovable, pointy-eared half human half Vulcan, is all head; he's a cerebral problem solver unencumbered by the distractions of feelings. He's ice.This book on our internal voices was more self-help than philosophical, but still pretty decent. I think I was most interested in his advice on advising others. He goes into say how listening to others but ONLY empathizing with their negative feelings can reinforce their own negative chatter. Learning to subtly reframe and contextualize a negative experience, without denying the validity of what they're saying, is a delicate operation!
The key to avoid rumination is to combine the two Starship Enterprise crew members. When supporting others, we need to offer the comfort of Kirk and the intellect of Spock.
I probably need some less heavy-handed ramp up to "well, it's all the heat death at the end of the universe anyway, and this problem clearly doesn't rise to that level, so why worry about it?"
I would say, I think the more interesting analysis of old Star Trek is not a duality but tripartite: Spock as Brain, McCoy as Heart, Kirk as mediating Guts and Spirit.
