No emotions means no passion, no excitement, no desire, no spirituality. Emotions add color to an otherwise black and white world. I write as someone who lost his emotional capacity suddenly due to a more than two dozen epileptic discharges in my temporal lobe. I was easily able to contrast my former life with a full range of emotions vs life without positive emotions. There is no real comparison. After the loss of my positive emotions, my family seemed alien. I assume this was because the emotional context of my memories of them were missing. I lived on my intellect until my I regained some of my former emotional capacity. It was only with that recovery that life became worth living again.
