Axiomatic Theory, Informative Value of Propositions, and "Derivation Rules of Ordinary Language"

Abstract

We present a logical analysis of Hans Zetterberg's strategy of axiomatic construction, especially his derivation of ordinary from theoretical propositions. Using formal criteria for assessing the relative logical or empirical content of propositions, we show that not only is Zetterberg's distinction vague but his derivation rules are logically faulty, and his assessment of the relative informative value of propositions is inconsistent. Thus we argue that Zetterberg failed to produce a coherent strategy for theory construction. Finally, we suggest that for the critical analysis of strategies of theory construction in sociology in general, the logical apparatus of modern symbolic logic and nondeductive inference be used.
