This paper proposes that, in spite of some fundamental invariant aspects, the way of exposition of the Minsky's work central concept - the so called Financial Instability Hypothesis - changed significantly throughout his academic productive period; furthermore it assesses the traditional way this concept is exposed does not incorporate important elements from the latest and more mature Minsky's contributions. The paper still states this canonical way to be insufficient to treat contemporary financial crisis phenomenon for lack of updating which incorporates recent institucional changes.
