Abstract

The paper addresses the way in which modern linguistics, − in particular, but not exclusively, the generative tradition − , has constructed its core concepts. It argues that a particular form of construction, reminiscent of, but crucially different from, abstrac- tion, which is dubbed ‘idealisation’, plays a central role here. The resemblances and differences between abstractions and idealisations are investigated, and consequences of the reliance on idealisations are reviewed.
