Communication and morality are two essential human features. While communication tries to make one's existence meaningful in society; morality is concerned with one's values and merit. Both concepts naturally imply action. If both come side by side, they form the combination implying existence's meaning and merit that in this point, we confront philosophy. Today, the nature of media, as well as the nature of communication, has been changed through new media technologies. New media, also known as digital media, brings edncal problems with it. It seems that the debates on new media and ethics have been performed mostly within the framework of old media's criteria. In this paper, while attempting to touch on these disputes philosophically, so have we attempted to examine the ethical codes of individuals actions and behaviors in the context of the source of morality in social media, which constitutes one of the most important parts of new media. Some theories concerning the source of morality directly entail analysis of the human being, itself. In this respect, two different approaches have arose, Kant's and Hume's philosophical analyses; which of these philosophers' perspectives is more explanatory will be scrutinnized in the context of this topic.
