Goetz ACKNOWLEDGMENTS This book is a record of a conference on "The concept of matter" held at the University of Notre Dame fromSeptember 5 to September 9, 1961. The papers forthe conference were contributed inadvance and circulated among those invited toparticipate.Writtencriticismsand suggestions weresolicited, and several of the papers were modified by their authors in the light of these advance discussions. At the conference itself, the papers were pre- sented only in summary and a formal comment on each was read by one of the participants. Each paper was then discussed in detail by the group as a whole (numbering thirty people), and the proceedings were audio-taped. After the conference, most of the essayists rewrote their papers in the light of the points raised at the conference. The papers, as we have tiiem Two here, are thus the final product of a long process of dialogue. extra papers (those by Drs. Hesse and Woodruff) were added subsequently, as well as the comment by Dr. Feigl, reprinted from The Philosophy of Sci- ence. In addition, some of the formal comments given at the conference have been included, though limitations of space unfortunately made it im- possible to reproduce all of them. Finally, sections of the conference discussion were transcribed from tape, and some edited excerpts are reproduced here in order to give the reader some idea of what went on. Choice of the excerpts was necessarily a very subjective matter on the part of the editor; almost any section could have been chosen. The aim was to find the pieces that would best illuminate the papers, or present some point not raised in the papers, or illustrate a funda- mental disagreement between the participants. For, as the reader will soon note, there tve^-e disagreements of a deep-rooted philosophical sort, as well as differences on questions of historical, philosophical and scientific detail. But it was interesting to notice at the conference itself a consensus develop on many issues that at the outset seemed hopelessly controverted. We hope that the reader may, as he works through the book, come to share, at how- ever many removes, in the excitement and tension of the original dialogue. In addition to the essayists and commentators whose work is reproduced below, the following also took part in the conference discussions: Robert Acknowledgments Cohen (Physics, Boston University); Catesby Taliaferro (Mathematics, Notre Dame) Drs. John Oesterle and Ralph Mclnerny (Philosophy, Uni- ; versity of Notre Dame) Father Edward O'Connor, C.S.C. (Theology, ; Notre Dame). Three of the essayists were unable to attend the conference: Drs. Lejewski and Hall, and Father Luyten, O.P. Two points of editorial usage may be noted. The phrase, 'primary mat- ter', was agreed upon as the best contemporary rendering of the Greek prote hyle, and this has been made uniform throughout the papers. Sec- ondly, typography has been pressed into the service of semantics in a way to which readers of American philosophy are becoming accustomed. Single quotes are used for mention only, i.e. in order to name the expression they enclose. Double quotes are used not only for quoting material, but also (in the case of words or phrases) to indicate a special sense of the expression they enclose. Italics are used either for emphasis, or to indicate the foreign character of the expression italicized, or lastly, to warn that the italicized term is to be understood as referring to the concept associated with it, in- stead of to its normal concrete referent. (Thus, for example, one would use italicstosaythatmatterunderwentanevolutionintheseventeenthcentury.) Our thanks must go first and foremost to the National Science Founda- tion,withoutwhoseaidthepublicationofthisbook wouldhavebeenimpos- sible. Their grant ofa substantial portion of the printing cost encouraged us to proceed. Secondly, to the University ofNotre Dame which supported the original conference, and made its resources available for the preparation of this manuscript.Lastly,tothemany who aid^dsogenerously alongtheway: Paul Schrantz, Janice Coffield, Ruth Hagerty, Mary Mast, Sr. M. Jeremiah, I.H.M., Sr. M. Petrus, R.S.M., who helped with thelarge task oftypingand mimeographing; Joseph Bellina, who took charge of the audio-taping; Patricia Crosson who compiled the Index; and the staff of the University Press, especially Charles Mc Collester, for their patience, planning and perseverance.
