Although first published in 1969, the methodological views advanced in Quentin Skinner's “Meaning and Understanding in the History of Ideas” remain relevant today. In his article Skinner suggests that it would be inappropriate to even attempt to write the history of any idea or concept. In support of this view, Skinner advances two arguments, one derived from the philosophy of the later Wittgenstein and the other from that of J. L. Austin.In this paper I focus on the first of these arguments. I claim that the conclusion which Skinner draws from this particular argument does not necessarily follow and that an alternative assessment of the methodological significance of Wittgenstein's philosophy for historians of ideas is possible. On this alternative view, far from ruling out conceptual history, an appeal to the view of meaning set out in Wittgenstein's Philosophical Investigations leads to a quite different conclusion, namely that the writing of such a history is arguably a necessary precondition for the elucidation of the meaning of a number of the core concepts in the canon of the history of political thought.Skinner's views have changed somewhat since 1969. Indeed, from the mid 1970s onwards he came to relax the strict opposition to the idea of conceptual history to which he was then committed. The paper concludes by noting that this evolution in Skinner's thinking has made him much more sympathetic than anybody reading “Meaning and Understanding in the History of Ideas” would have imagined to the research project of the Begriffgeschichte School of conceptual history.
