"Except our own thoughts, there is nothing absolutely in our power"
About this Quote
The line works because it is both bracing and quietly alarming. "Absolutely" is the tell. Descartes isn't claiming we usually steer our lives; he's insisting that if you demand total certainty, the list of controllables shrinks to a single item. That absolutism is the engine of his method: doubt everything that can be doubted until you hit bedrock. The subtext is a kind of intellectual bunker mentality, not paranoia but precision. If you can't guarantee your body, your reputation, your perceptions, even the existence of an external world, then philosophy must start where guarantees are possible: the internal act of thinking.
Calling Descartes a mathematician matters here. This is the mindset of someone trained to prefer proofs over plausibility, axioms over vibes. The sentence reads like an axiom for a new kind of person: the modern subject, defined less by place, church, or king than by an interior realm that no empire can annex. It's liberating, but it also sets up a lonely bargain: if certainty lives only inside your head, then the world becomes something you must rebuild from scratch, one rigorously justified step at a time.
