How they work
CBT
Core mechanism: Identifying and restructuring cognitive distortions + behavioral experiments + exposure reduces maladaptive appraisals and avoidance
Ontology: Dysfunctional cognitions (automatic thoughts, core beliefs) that distort appraisal of self, world, and future
MBCT
Core mechanism: Mindful awareness of depressive cognitive patterns enables decentering and prevents ruminative relapse spirals
Ontology: Depressive relapse maintained by reactivation of ruminative cognitive patterns triggered by low mood

What each assumes — and misses
CBT
Philosophical roots: Epictetus, Marcus Aurelius (Stoic appraisal theory — it is not things that disturb us but our judgments); Kant (rational autonomy); Popper (falsifiability as therapeutic method); Ellis cited Stoics explicitly
Blind spots: May underemphasize attachment history, relational dynamics, and the therapeutic relationship itself as mechanism of change
Therapeutic voice: What evidence do you have for the thought that nobody cares about you?
MBCT
Philosophical roots: Buddhist psychology (mindfulness, non-attachment to thoughts); Husserl (epoché — suspending natural attitude); Kabat-Zinn (secularized dharma); Teasdale (interacting cognitive subsystems)
Blind spots: Primarily relapse prevention — not first-line for acute depression; requires meditation capacity some clients lack
Therapeutic voice: Notice the thought arriving — not as truth, but as a mental event. Thoughts are not facts.
Choosing between them
CBT and MBCT both sit within the Cognitive-Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
