A recent pixar movie suggested that sadness was vital to our emotional wellbeing, as it is what makes us seek the help of others. I wanted to explore this further.
In a world without sadness, we would always choose another emotion to feel when something "sad" happened. (Anger, fear or joy are examples given in the movie).
Would this be beneficial, following a similar method to Socratic dialogue, whereby a person should only agree or add a suggestion, but never disagree. Socrates suggested this was a far more productive method of discussion than allowing negative attitudes.
To simplify the question - would society evolve faster in a positive direction if sadness (and depression, loneliness, apathy and all other associated feelings) were eliminated, but all other emotions remained?
