Kerschagl’s study is a rehabilitation of John Law and a genealogy of modern monetary institutions. Against the inherited image of Law as mere gambler, fraud, or adventurer, Kerschagl reads him as a flawed but decisive inventor of modern finance: not the creator of paper money as such, but the first thinker-practitioner to join centralized note issue, legal-tender status, giro accounts, and joint-stock speculation into one state-supported system.
John Law ist keineswegs der Erfinder der Banknoten gewesen, wohl aber der Schöpfer der ersten zentralen Notenbank.
English translation: John Law was by no means the inventor of banknotes, but he was indeed the creator of the first central bank of issue.
The book is structured expansively: a biographical reconstruction, a technical analysis of the French experiment, “lessons” for the present, a survey of Law’s writings, separate chapters on his errors and valid insights, portraits of his circle, Louisiana, the assignats of the French Revolution, and the giro banks that preceded modern note banks. This architecture is central to Kerschagl’s argument: Law can only be judged by connecting theory, institutional technique, court politics, colonial fantasy, and later inflationary experience.
Law’s conceptual starting point, as Kerschagl presents it, is monetary activism. Money is a condition for employment, trade, and state capacity rather than a mere ornament of exchange. This is why Kerschagl repeatedly links Law to later figures such as Knapp and Keynes, even when he sharply rejects the inflationary implications.
Ohne Geld bleiben die besten Gesetze wirkungslos, welche darauf aus sind, allen Menschen Beschäftigung zu verschaffen
English translation: Without money, even the best laws aimed at providing employment for all remain ineffective.
The strength and danger of Law’s thought lie in this same premise. He sees credit as circulation, almost as a physiological condition of the state:
Das Geld ist im Staate dasselbe, was das Blut im Körper ist
English translation: Money is in the state what blood is in the body.
Kerschagl’s technical account shows how this metaphor became policy: the Banque Générale became the Banque Royale; notes moved from state payments to general legal tender; the Compagnie des Indes fused colonial promise, public debt conversion, and share speculation; banknotes, shares, rents, and giro balances became “communicating vessels.” The Mississippi bubble was therefore not an accidental corruption of a sound banking idea, but the result of combining state fiscal hunger, speculative equity issue, and a theory that blurred money, credit, and capital.
Kerschagl is most critical where Law sought a “real” limit for paper issue in land. Law’s belief in Bodenwert as monetary foundation appears to Kerschagl as a physiocratic illusion: land is productive only through future yields, not immediately available consumer goods.
Der Boden ist dasjenige, das ganz offenkundig seinen Wert am besten zu bewahren vermag
English translation: Land is that which, quite manifestly, best preserves its value.
For Kerschagl this is Law’s decisive theoretical failure. A note issue backed by productive assets still creates present purchasing power before corresponding consumer goods exist; the interval is inflationary. Law’s second great error is the repeated confusion of credit with capital. The phrase that best captures both insight and danger is:
Die Banknote ist nichts anderes als eine Anleihe ohne Zinsen
English translation: The banknote is nothing other than an interest-free loan.
As description of state paper this is powerful; as a basis for unlimited credit creation it is disastrous. Yet Kerschagl insists that Law also grasped truths later rediscovered: the psychological role of convertibility, the importance of legal-tender law, the monetary significance of payments to and from the state, and the superiority of centralized note issue over local deposit certificates.
Das Geld ist das Mass, mit dem alle Waren gewertet werden.
English translation: Money is the measure by which all goods are valued.
The comparison with the assignats of the French Revolution deepens the argument. Law’s inflation was bank-based, court-driven, and speculative; the revolutionary inflation was state-note inflation backed by confiscated property and terror. Both ended in demonetization, but the latter lasted longer because France’s social product and coercive apparatus had grown. Kerschagl’s conclusion is starkly modern:
Nach jeder wirklich grossen Inflation kommt keine reelle Deflationsmöglichkeit mehr, sondern das Nichts
English translation: After every truly great inflation there is no longer any real possibility of deflation, but only nothingness.
The relevance of the book lies in this double judgment. Law inaugurates modern central banking, paper money, giro technique, and the bearer share; he also inaugurates modern inflationary temptation, the “alchemy” of printed paper. Kerschagl’s core move is therefore not to acquit Law, but to separate invention from illusion: the modern banknote was born together with the modern warning against mistaking credit expansion for real capital formation.
