As mentioned elsewhere "Science of Survival" is an excellent source for this as regards the SUBJECT of scientology. Generally speaking scientology recognizes and acknowledges the role that free emotion plays in life & living.
The question of "stuck emotion" or "inappropriate emotion" however is generally regarded as indicative of "case" and suggestive of the need for auditing to relieve that "case". By "stuck emotion" is meant an emotional state that doesn't shift, such as a person who is perpetually angry, or one who is stuck chronically in grief. Similarly "inappropriate emotion" would be an emotional response which seems out of proportion or not in keeping with whatever stimulus may have triggered the response.
In contrast the cult of the Co$ often uses ANY emotional response as a "make wrong" and as evidence of the "need to handle", preferably by an expensive program of auditing or other approved Co$ service. This is, of course, a clear violation of the fundamentals of scientology, but nothing new there.
