Introduction

My special thanks are due to Dr Paul Joseph Chu who proofread all the texts and who collaborated on the whole project of the collected writings of the Lvov-Warsaw School (in preparation for publication in separate volumes). I am also indebted to Gwen Burda for her linguistic correction, Stanisaw Judycki for his comments and Zofia Kolbuszewska for her linguistic remarks. My student Lila Wesierska helped me with the bibliographical research. Kazimierz Dudkiewicz and Jarek Kinal from the University Computer Centre assisted me in solving all technical questions. Due to my fellowship at the Catholic University in Leuven (August-September 1994) where I was able to work in the Husserl Archive, it was possible to prepare the editorial addition to the bibliography. I would like to thank also the Polish Scientific Publishers for their permission to include the following essays in the present collection: K. Twardoswski, Imageries (see Twardoswki 1965], 114–148), K. Ajdukiewicz, The psychophysical nature of humans (see Ajdukiewicz 1985], vol. 1, 317–324). Ajdukiewicz's paper is translated here by kind permission of Mr. Bron Ajdukiewicz. I would like to extend my grateful thanks to Kluwer Academic Publishers and to Prof. Robert S. Cohen for their kind permission to publish H. Mehlberg's paper On psychophysical parallelism (a modified version of this paper appeared as a supplement in Mehlberg 1980], 261–285]).
