True, Joe.

Re premises and Cognitive therapy and fallacies - when it comes to therapy people often start out operating from a complex set of assumptions that they simply have never questioned and mistake for 'truth.'

To function in the world we must operate from assumptions, but it is very useful to understand them as just that - assumptions, not 'truth.' Belief, which encompasses much more than spiritual or religious beliefs, are assumptions that are mistaken for 'truth.'

Values are assumptions that usually are mistaken as 'truth.'

I don't ever tell some one in therapy that their assumptions are wrong, because I don't know that for a fact. I simply invite them to understand that assumptions and beliefs, by definition, are not fact, suggest they identify their core beliefs about themselves, others and the world, then examine those beliefs and evaluate how well those beliefs actually work for them in their own lives and relationships.
