'The debilitating effect of logical positivism' On the difference between R.G. Collingwood's An Essay on Philosophical Method and An Essay on Metaphysics

It is generally agreed that R.G.Collingwood's An Essay on Philosophical Method and An Essay on Metaphysics are closely related but are also significantly different. If they do in fact differ in any significant way, one wonders whether there are good reasons to prefer one account over the other at the points where they differ. In this article, I would like to try to answer this query by referring to two passages, where the text in both essays is nearly identical but which nevertheless reveal the differences between the two essays. In these passages Collingwood gives a presentation of Plato's and Kant's philosophical method and compares their methodologies to his own. Precisely the small differences between the two fragments not only show the continuity between both essays, but also make clear how Collingwood's concept of metaphysics after 1936, under the pressure of logical positivism, loses its distinctive sharpness and hence becomes liable to the charge of relativism and historicism. If my analysis has any plausibility, I hope to make it clear that Collingwood's position in EPM is preferable to that of EM or, to put it more mildly, that 'any account of EM must do justice to EPM if we are to allow the rest of Collingwood's philosophy to live and flourish'.
