Very imperfect translation from the French, aided by Google Translate:
According to you, my dear critic, there remains in my political economy actions without reasons, facts without explanation, a string of reports whose extremities are lacking and whose most important rings are broken. I share Adam Smith’s misfortune, one of our critics said he had retrograde political economy.
( J.B. Say to Tanneguy du Châtel, quoted in Friedrich List’s The National System of Political Economy, 1841.)
Not quite a smackdown – the rest are worse.
