What is emotion?: and is it necessary and sufficient for moral judgments?

In recent years, Humean sentimentalism that grounds moral judgments in sentiments has enjoyed resurgence. One contributing factor may be the works of the prominent philosopher Jesse Prinz, who has notably claimed that emotion is necessary and sufficient for moral judgments. I agree with Prinz that emotions play an essential role in our lives; but I disagree that moral judgments are essentially grounded in emotions. Instead, I claim that moral judgments are grounded in many ways that we interact with our environment such as cognition, perception, intuition, experience, as well as emotion. This thesis explores Prinz's evidence for his claim.
