Gratitude is defined as a moral emotion because it is mainly motivated by and results from behavior that shows concern for the well-being and well-being of another. Therefore, gratitude as a moral emotion is included in the list of gratifying emotions. Although the definition of gratitude and its analysis seem very simple at first glance, in the following article four basic challenges to its common definition have been raised and analyzed. These four challenges revolve around another issue, will, benevolence, and benefit. Whether the stimulus for the feeling of gratitude must necessarily be a response to voluntary and extra-duty behaviors or not has been discussed in this regard. The literature on gratitude has been formed based on two approaches: two-part gratitude and three-part gratitude. We sometimes see ourselves in front of God or existence or nature or an abstract idea or concept and see ourselves obliged to be grateful. Recently and sometimes this phenomenon is called existential gratitude. That is, gratitude for life or existence as a whole, as opposed to gratitude for a specific benefit or a specific person.
