This chapter explores the foundations of emotions from empirical research in neuroscience, biology, psychology, multiculturalism, and primatology. The phenomenon of emotional experience is depthless and ever complex. The reader learns to appreciate how social and emotional intelligences are necessary if one is to learn the nature of emotions. Cultural meanings, languages, and world paradigms may seek to define emotions. However, this chapter argues that by developing a multicultural humanistic psychology approach to understanding emotions, readers can appreciate their flowing nature that is not known by definition, but through relationship.
