Some were also interested in seeing his contributions to journals and conference proceedings collected together in a book. At the request of the managing committee of the Imre Lakatos Appeal Fund we have prepared two volumes of selected papers which we hope will meet these demands. None of the papers published here for the first time was regarded by Lakatos as entirely satisfactory. Some are early drafts, while others seem not to have been intended for publication. We have pursued a fairly liberal policy, including papers which, at least in their present form, Lakatos would not have allowed to go to print. As for previ- ously published papers, we have included them all except for the two papers, 'The Role of Crucial Experiments in Science' and 'Criticism and the Methodology of Scientific Research Programmes', which would have introduced undue repetition, and except for Proofs and Refutations, which recently appeared in book form. Volume 1 is a collection of Lakatos's best known articles developing the methodology of scientific research programmes, together with a hitherto unpublished essay on the effect of Newton's scientific achievement, and a new 'Postscript' to the already published paper on the Copernican Revolution. Although Lakatos perhaps came to be better known for his work in the philosophy of the physical sciences, he regarded himself as primarily a philosopher of mathematics. Volume 2 contains papers on the philosophy of mathematics, as well as some critical essays on contemporary philosophers, and some short polemical pieces reflect- ing his concern with political and educational matters, which, among other things, give an impression of his forceful personality. Information about the history of the material published here is included as introductory footnotes to each paper. These and other editorial footnotes are indicated by asterisks. (We have tried to minimise these editorial footnotes particularly in the case of previ- ously published papers.) Offprints of some of the published papers found in Lakatos's library contained handwritten corrections and we have incorporated Downloaded from https://www.cambridge.org/core.

In preparing the previously unpublished papers for the press, we have taken the liberty of introducing some presentational alterations where the original text was incomplete, or seemed likely to be misleading, or where minor alterations seemed to produce major increases in readability. We felt justified in making these changes because Lakatos always took great care over the presen- tation of any of his material which was to be published and, prior to publication, he always had such material widely circulated among colleagues and friends for criticism and suggested improvements. These newly published papers would undoubtedly have undergone this treatment and the resulting changes have been much more far reaching than those we have dared to introduce. Wherever the device of enclosing our alterations within square brackets worked easily and
