DON'T BELIEVE EVERYTHING YOU THINK: Why Your Thinking is the Beginning & End of Suffering, Expanded Edition

Review

SECTION ONE Joseph Nguyen's Don't Believe Everything You Think begins from a deceptively simple observation: most human suffering does not arise from what happens to us but from the stories we tell ourselves about what happens. The book's thesis is that the thinking mind, left on autopilot, generates a near-constant stream of evaluations, predictions, and self-condemnations — and that the ordinary person's habit of treating every one of those outputs as a reliable report about reality is the engine of anxiety, shame, and paralysis. Nguyen argues that the resolution is not to think better thoughts but to step outside the identification with thought altogether: to notice that you are the one observing the mind, not the mind itself. The book is addressed to anyone who has found themselves trapped in cycles of overthinking, self-doubt, or chronic worry, and it asks them to consider that the exit is not through better arguments but through a change in relationship to the inner voice. The expanded edition adds practical exercises and extended reflection prompts to the original's framework. SECTION TWO - **Created**: Nguyen's insistence that the human being possesses an awareness that is prior to and distinct from the chattering mind implicitly honors the rational soul's capacity for self-reflection — what the CCMMP, drawing on Aquinas, calls the intellect's reflexive power. The book treats the person as capable of standing in a witnessing relationship to their own cognition, which affirms the dignity of rational self-governance rather than reducing the person to a bundle of automatic reactions. - **Fallen**: The book gives an accurate phenomenological account of what Aquinas called the passions in their disordered state: thoughts that intrude, attach, and escalate without the person's deliberate consent. Nguyen does not use the language of concupiscence, but his description of the thinking mind as a system that turns on its owner — generating suffering from the very tools meant to solve problems — maps onto the CCMMP's Fallen premise that the interior life is wounded and requires attention, not merely information. - **Redeemed**: The book's movement toward healing is consistent with the Redeemed state at the level of interior freedom: the reader is invited not to suppress or defeat unwanted thoughts but to loosen their grip through a change of perspective. This is analogous to what John of the Cross calls the active night of the intellect — the deliberate withdrawal of credence from consoling or distressing mental contents so that the person is not enslaved to them. Nguyen reaches this conclusion without theological scaffolding, but the structural movement is recognizable. - **Prudence (circumspection)**: The book trains the reader in the integral virtue of prudence-alertness — the careful attention to what is actually occurring in the interior before acting from it. Nguyen's exercises in noticing thought patterns before believing them are a secular form of the examination of consciousness that Catholic spiritual direction has long recommended as a condition for wise action. - **Prudence (docility)**: The expanded edition's tone is explicitly teachable: Nguyen positions the reader as a learner unlearning a bad habit rather than as someone who needs more information. This posture of intellectual humility before experience aligns with prudence-teachability, the openness to being corrected by reality. SECTION THREE The book sits in close structural conversation with Hayes[^1] (ACT), whose 'mind-train' exercise in Get Out of Your Mind and Into Your Life asks the reader to imagine observing thoughts as ore-laden cars on a slow freight train — visible, passing, but not requiring the observer to climb aboard.[^1] Where Hayes arrives at this posture through Relational Frame Theory and the concept of cognitive defusion, Nguyen reaches the same destination through a more intuitive, narrative-driven route; the practical upshot for the reader is nearly identical, and the books work well together. Readers may find Nguyen the more accessible entry point and Hayes the more theoretically grounded complement when they want to understand why defusion works rather than simply how to practice it. ## References 1.

✓ Strengths

• ✓The book's central premise — that thoughts are not facts, and that suffering arises largely from uncritical belief in every thought the mind produces — aligns with Aquinas's account of the cogitative sense and disordered interior passions: the problem is not having a thought but being seized by it as though it were reality.
• ✓Nguyen's insistence that the deepest human suffering comes from mental self-attack rather than from external circumstances implicitly affirms the dignity of the person as one who stands in some relation to, rather than being wholly determined by, their own cognition — a point consistent with the CCMMP premise of rational self-governance.
• ✓The book's practical orientation toward noticing and releasing thought patterns rather than suppressing them supports the integral virtue of circumspection (prudence-alertness): it trains the reader to pause and examine internal states before acting from them.
• ✓Nguyen's framing of emotional suffering as a signal worth attending to, not a malfunction to eliminate, is consonant with the Thomistic view that the passions are morally and anthropologically significant — ordered or disordered, they are not noise but data about the person's interior life.
• ✓The expanded edition's attention to self-compassion as a precondition for genuine change resonates with the CCMMP's Redeemed state: healing is not mere cognitive correction but involves a shift in the person's fundamental orientation toward themselves and others.

⚠ Considerations

• ⚠The book operates within a secular mindfulness framework and treats the mind's 'natural state' as inherently peaceful — a claim that bypasses the theological reality of concupiscence, the tendency of the will toward disordered ends even apart from anxious thoughts. Readers should not assume that quieting unhelpful thoughts is equivalent to moral or spiritual formation.
• ⚠There is no account of an external referent — God, moral law, or a community of virtue — against which one might evaluate whether a thought is disordered versus truthful. The implicit anthropology is self-referential: the self judges its own thoughts by consulting a presumed inner peace, which is epistemologically thin from a realist standpoint.
• ⚠The book's practical exercises are drawn from popular mindfulness traditions without acknowledgment of their Buddhist conceptual origins. Catholic readers seeking a fully integrated framework will need to supplement Nguyen's approach with formation-oriented sources that ground the practice of mental detachment in a theology of the person.
