Robert Zuckerkandl, “Schlettwein, Johann August”

Robert Zuckerkandl’s biographical article, first published in 1890 and supplied here in a republication of undocumented date, examines Johann August Schlettwein as an administrator, teacher, and German advocate of physiocracy. Its chronological narrative culminates in a qualified assessment: limited originality and subsequent neglect do not erase the independence required to support doctrines that challenged established policy.

Born in Weimar in 1731, Schlettwein studied law and cameral sciences at Jena. His early writings extended into theology, natural science, logic, and metaphysics. Zuckerkandl makes this breadth a defining intellectual characteristic:

Seine Studien waren jedoch nicht auf ein Fach beschränkt, wie aus seinen ersten Schriften klar genug hervorgeht.

English translation: His studies were, however, not confined to a single field, as emerges clearly enough from his first writings.

This range anticipates Schlettwein’s prolific authorship and expansive teaching ambitions. His appointment to Baden’s service in 1763, however, gave political economy an immediate practical importance:

Jedenfalls brachte Schlettwein's Stellung für ihn die Nothwendigkeit mit sich, der Staatswirthschaftslehre erhöhte Aufmerksamkeit zuzuwenden.

English translation: In any case, Schlettwein's position brought with it the necessity of devoting increased attention to the theory of state economy.

Zuckerkandl does not settle whether Schlettwein converted Margrave Karl Friedrich to physiocracy or received the decisive influence from the prince. Instead, he emphasizes their collaboration in making Baden a testing ground for the physiocratic “natural order.” In Dietlingen, Thendingen, and Bahlingen, existing levies were to yield to a single tax on the net produce of land, together with greater commercial freedom. Net yields were assessed so that approximately twenty percent corresponded to the villages’ previous tax payments. This fiscal detail anchors a universal doctrine in administrative constraints.

Die Verwirklichung der natürlichen Ordnung zunächst in diesem engen Rahmen war Aufgabe Schlettwein's.

English translation: The realization of the natural order, initially within this narrow framework, was Schlettwein's task.

The experiment also explains the political function of Schlettwein’s economic publications of 1772. They defended reforms for which he bore responsibility as a prominent adviser, linking theory, public persuasion, and governmental practice. Yet the alliance with princely authority proved unstable: Schlettwein lost his position and left Karlsruhe in 1773. Zuckerkandl suggests that rapid advancement, forceful conduct, and self-confidence created enemies, while leaving the precise causes of his dismissal uncertain.

After unsuccessful efforts to obtain another appointment and a period in Vienna, Schlettwein taught at Basel with support from the physiocratic sympathizer Iselin. His projected instruction encompassed natural law, administration, commerce, agriculture, and scientific subjects, although only part of this programme materialized. In 1777 he joined the new economic faculty at Giessen. His Grundveste der Staaten oder die politische Oekonomie appeared in 1778 and, alongside Die wichtigste Angelegenheit für das ganze Publicum, provides a principal basis for Zuckerkandl’s evaluation. The Archiv and Neues Archiv, supplied entirely by Schlettwein himself, further attest to his productive energy. Following his resignation in 1785, his attention increasingly turned toward public law and politics. He died in 1802.

The article locates Schlettwein’s lasting significance chiefly in his dissemination of physiocracy, while identifying departures from its received doctrines. His later writings elevated population growth into political economy’s foremost purpose. Production of food, clothing materials, and housing resources consequently took precedence over pleasures or activities thought to reduce subsistence. Zuckerkandl connects this priority with Schlettwein’s hostility to horse breeding, tobacco cultivation, and even mining. He finds Schlettwein’s indifference to the domestic or foreign origin of manufactures difficult to reconcile with these commitments, and regards some of his monetary views as eccentric.

Zuckerkandl also historicizes Schlettwein’s method. Economic propositions are deduced from axioms as though they were mathematical truths valid for every people and period. This confidence exemplifies an eighteenth-century overestimation of reason’s command of economic affairs. Schlettwein’s benevolent rhetoric likewise belongs to the literary sensibility of his time, without thereby becoming insincere.

The concluding judgment distinguishes intellectual reputation from historical achievement. Adam Smith’s ascendancy displaced physiocracy, while readers interested in its doctrines preferred the French sources. Schlettwein’s neglect thus reflects changes in economics as well as his own limitations. For Zuckerkandl, embracing the natural order nevertheless demanded unusual independence because its practical implications threatened prevailing economic arrangements. His biography recovers German physiocracy as a reform commitment whose significance lay in administration and public advocacy as much as in theoretical innovation.
