The Four Agreements
The Four Agreements is Don Miguel Ruiz’s short book of practical ethics, published in 1997 and drawn from Toltec teaching. Its premise is that most of what governs a person’s behavior was agreed to long before that person could evaluate it: rules absorbed in childhood from family, school, and culture, then defended later as if they had been chosen. Ruiz proposes replacing that inherited code with four deliberate agreements, which are to be impeccable with your word, take nothing personally, make no assumptions, and always do your best. What makes the book useful beyond its self-help shelf is the underlying move: it treats a belief as something a person consents to rather than something that simply is true, which makes an old agreement reviewable and, in principle, replaceable.
