Richard Thurnwald, “Achelis, Thomas”

Richard Thurnwald’s biographical encyclopedia entry, first published in 1930 and republished in 1937, presents Thomas Achelis (1850–1909) as a German sociologist and anthropologist whose methodological contribution deserved greater recognition. Its compact structure moves from education and employment to intellectual positioning, then concentrates on Achelis’s conception of sociology before closing with a bibliography.

Achelis studied philosophy and philology at Göttingen, taught at the Bremen gymnasium from 1874, and became editor of the Archiv für Religionswissenschaft in 1898. Thurnwald distinguishes his philosophical-psychological approach to anthropology from the materialistic-physiological emphasis then prevailing in Germany, identifying this difference as the reason for attacks by the Berlin school. In sociology, Achelis’s resistance to dominant Hegelianism likewise limited the influence of his Soziologie. Thurnwald’s assessment is explicitly appreciative: the treatise received less attention than its historical contribution warranted.

The account locates that contribution in a movement from biological conditions toward psychological interpretation:

According to Achelis, sociology is a study of the forms of human association, taking as its starting point man in his biological aspects and proceeding to a psychological explanation of associations.

Biology supplies a starting point, rather than an exhaustive explanation of social life. Sociology’s principal task is to establish the structures of different social formations and, where possible, identify laws of relationship or recurring rhythms. Thurnwald characterizes this procedure as more inductive than earlier German approaches, while qualifying the search for laws: recurring patterns remain significant even where stronger explanatory regularities cannot be established.

Achelis’s inductive orientation nevertheless leaves room for purposes that mechanical explanation cannot encompass:

However, he is by no means extreme; indeed, in concluding his chapter on principles and methods, he demands as supplementary the consideration of “teleological necessities,” because in social life motives and purposes constitute a residue not to be explained by the principle of mechanical causality.

The entry’s central conceptual move is thus the conjunction of structural inquiry with attention to meaningful action. Its concluding bibliography situates this sociology within Achelis’s wider work on ethnology, marriage, religion, ethics, education, and ecstasy. Thurnwald offers a brief historical appraisal of a method that sought empirical regularities without reducing human association to mechanical causation.
