Emotions

Emotions are very treacherous phenomena. They feels like innate and biologically certain but in fact they are very statistical in nature and change from subject to subject, culture to culture and context to context. The venture of defining emotions, since james and lange, most likely to have two sides biological marker theory of emotions and cognitive theory of emotions. But, for the last century bio-marker theory of emotions including facial marker, physiological marker and neural marker was more prevalent. Cognitive theory of emotions mostly include appraisal theories, socially real emotions, and recently proposed active inference theory of emotions.
