In Emotional Intelligence 2.0 it is stated:
We have so many words to describe the feelings that surface in life, yet all emotions are derivations of five core feelings: happiness, sadness, anger, fear, and shame.
This chart is used to categorize different feelings under these core emotions.
Interesting that there are 4 negative and only 1 positive core feeling. Also to note there is 'Heartbroken' in the sad category. However, is there is no 'love' feeling to match 'Heartbroken'.
Hence, the main question: Does the current psychology understanding back up this sort of categorization? And is 'love' really non-existent as a discrete feeling?
