I have to disagree. My biggest complaint (if I could call it that) with his previous book, The Black Swan, was that it lacked practical application of his principles, e.g., he exposes the hidden prevalence of asymmetries but doesn't place them within the broader context of how one should live. Antifragile does just that. His title alone is worth the price of the book. Antifragile describes something that gains from disorder rather than is merely robust to it, and we don't have a word in English to describe this
