Polarity vs. Orientation

[zenmaster]

I disagree that emotion is developmental.

You have what has been made conscious and what is still unconscious. The source of emotion is unconscious - for example libido or what not. In some manner this comes through to consciousness. For the less aware, this tends to be in the form of an unconscious reaction to something. But there is a process involved in becoming more aware and removing distortions. And one's affect is necessarily evolved. The temper-tantrum baby vs the temperament of the mature adult. The link I posted shows rather clearly the various stages.
