 Collingwood returned to the question of the role of philosophical analysis in his second metaphilosophical treatise, An Essay on Metaphysics (1940). While the commitment to the view that philosophy disambiguates concepts that coincide in their instances persists, Collingwood presents the role of philosophical analysis in a different way, by saying that philosophy’s task is to uncover the presuppositions of thought. This change of emphasis, as we shall see, is at least in part motivated by an attempt to present his metaphilosophical views in a language to which the emerging school of analytic philosophy would have been more receptive and to engage in a dialogue with A.J. Ayer’s logical positivist critique of metaphysics.
