Hermann von Schullern zu Schrattenhofen: Review of Benini’s Principii di Statistica metodologica (1907)

Hermann von Schullern zu Schrattenhofen’s short review evaluates Rodolfo Benini’s 1906 treatise as a comprehensive contribution to statistical methodology. Its endorsement is emphatic, but grounded in selected methodological problems rather than extended demonstration. Benini’s reputation and the absence of customary introductory appeals lead to the reviewer’s opening judgment:

Das Werk hat auch eine derartige Einführung gar nicht nötig und spricht für sich selbst.

English translation: The work has no need whatever of such an introduction and speaks for itself.

The review follows the treatise’s organization: a general part addresses basic concepts, statistics as a branch of logic, and the division of its subject; two subsequent books examine statistics as observation and as induction. Schullern singles out the concept of the typical and calls Benini’s opening definition somewhat complicated. In the German translations he supplies, statistics concerns quantitative observation and induction applied to variable masses of cases. Its task is to identify typicality, constancy, and probability within apparent diversity and contingency, and to investigate underlying causes within the limits of the method. This formulation makes statistics an inquiry into collective regularities, not simply a technique of enumeration.

Schullern’s selection of topics emphasizes the reliability of statistical knowledge. He praises the calm, objective discussion of errors in data collection, then stresses the dangers of faulty or superficial treatment of averages: methodological mistakes can produce consequential misunderstandings and practical errors. His observation that Benini approaches averages predominantly mathematically qualifies the account without becoming a sustained objection. Index numbers receive notice for their extensive technical and logical treatment, while an appendix connects observation to census practice, particularly the latest Italian census.

The treatment of induction receives a strong recommendation for close study, although the review gives few details of its argument. Schullern also notes a brief historical and bibliographical appendix and identifies Italian mortgage statistics as especially timely for Austrian specialists. The review thus moves from conceptual foundations through methodological safeguards to practical relevance across national settings. Its conclusion situates Benini alongside leading international scholarship and explicitly joins theoretical with applied readerships:

Beninis neuestes Werk reiht sich würdig an denselben Gegenstand behandelnde Studien der hervorragendsten Fachmänner anderer Völker an und verdient jedem theoretischen und praktischen Statistiker empfohlen zu werden.

English translation: Benini's latest work ranks worthily alongside the studies of the most eminent specialists of other nations that treat the same subject, and deserves to be recommended to every theoretical and practical statistician.

The review’s significance lies in this selective appraisal: it presents statistical methodology as the link between sound observation, disciplined inference, and responsible practical use, while directing readers to the parts of Benini’s work where those concerns are most visible.
