 In the 1930s Susan Stebbing and John Wisdom, founding what has come to be called the “Cambridge School of Analysis,” paid considerable attention to the notion of logical construction (see Beaney 2003). Stebbing (1933) was concerned with the unclarity over whether it was expressions or entities that are logical constructions, and with how to understand a claim such as “this table is a logical construction” and indeed what it could even mean to contrast logical constructions with inferred entities. Russell had been motivated by the logicist project of finding definitions and elementary premises from which mathematical statements could be proved. Stebbing and Wisdom were concerned, rather, with relating the notion of construction to philosophical analysis of ordinary language. Wisdom’s (1931) series of papers in Mind interpreted logical constructions in terms of ideas from Wittgenstein’s Tractatus (1921).
