Most of the papers collected here derive from the conference 'Philosophy of Mathematics Today', held in Munich from 28 June to 4 July 1993 and organized by the editor of this volume. The conference was generously sponsored by the Deutsche Forschungsgemeinschaft and received additional financial support from the Mind Association. I wish to express my gratitude to both institutions. I am also grateful to Crispin Wright for his proposal to apply for a grant from the Mind Association and to Peter Clark, in his capacity as Secretary of the Association, for strongly supporting my application. Many thanks are due to Uwe L-Űck for his help during the conference. I would also like to thank all the participants for creating a most pleasant atmosphere, stimulating and yet very relaxed, indeed conducive to an intense discussion of the philosophy of mathematics over nearly a week. Finally, it is a pleasure to thank Peter Momtchiloff of Oxford University Press for his interest in this volume, his collaboration, and his encouragement and friendly advice.
