A similar argument is applied in human emotions (that is, emotions are also influenced by reason). Damasio explicated, a]s organisms acquired greater complexity, 'brain-caused' actions require more immediate processing...Brains can have many intervening steps in the circuits mediating between stimulus and response, and still have no mind, if they do not meet an essential condition: the ability to display images internally and to order those images in a process called thought In this passage, Damasio made clear that, reason or emotion, the brain undergoes the same neurological processes that make the generation of either "reason" or "emotion" as an 'objective' task.

This analysis from Damasio has...

For years, humanity is able to explication human actions based on its rationality -- whether the action is sound and logical compared against actions that are motivated by emotion only. By arguing that both reason and emotion are the same and actually influence each other, ethics and morality can no longer be defined specifically. Actions can no longer be justified as rational or emotional in their motivation. Though at present, I find it hard to reconcile Damasio's arguments with my reality, his findings -- Descartes' error -- will surely change and perhaps improve the way we, as a civilization, view human actions, perceptions, and motivations.
