I've noticed I spend so much time thinking about thoughts and so little time feeling about feelings.
George Lakoff really influenced me toward a more positive perspective about feelings as both signals to be listened to and tools for understanding. He states that in the old fashioned popular view, emotion gets in the way of reason. This is simply not the case. Emotion is a necessary precursor to reason. If you can't feel, like and dislike would mean nothing to you. You become unable to differentiate and compare without feeling, both being necessary tools for reasoning. This is demonstrated especially in stroke patients whose brain areas responsible for emotion have been damaged, they become unable to effectively plan and their behavior becomes random.
*note added 6/8* - In making this point, it's important to add that the emotion area of the brain and the motor area responsible for movement and sensation have considerable overlap in neurons and connectivity.
Making sensory association has gone such a long way in building emotional awareness for me. Relating a sensation in the body to "feeling" has taken me attention and practice. Noticing a sensation and really paying it mind, not rejecting or avoiding it passively but even in a sense inquiring with it to ask "where do you come from, what are you trying to tell me."
Nurturing my own capacity for emotion has not reduced but hugely enhanced my ability to make decisions and to reason. Especially about some of the most important parts of life. Besides, emotion was playing a key role in those things before I paid it any extra attention. It's influence though was left to a clumsier, awkward and grasping set of choices without a voice to express itself.
