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
REBT
Core mechanism: Identifying and vigorously disputing irrational beliefs (demands, awfulizing, low frustration tolerance, global rating) and replacing them with rational preferences builds emotional resilience and unconditional self-acceptance
Ontology: Emotional disturbance is caused not by events but by rigid, absolutistic beliefs (musts and demands) about those events — a direct application of Epictetus

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?
REBT
Philosophical roots: Epictetus and Marcus Aurelius (Stoic philosophy — Ellis was explicit about this lineage); Popper (scientific method applied to beliefs); Russell (logical analysis); pragmatism; Spinoza (rational acceptance)
Blind spots: Confrontational style can rupture alliance; philosophical disputation may miss emotional and relational depth; can feel intellectualizing; less suited for trauma or severe personality disorders
Therapeutic voice: You say you absolutely must be perfect or you're worthless. Where is the evidence for that demand?
Choosing between them
CBT and REBT 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.
