These proceedings contain the papers presented during the 14th annual High Energy Physics meeting convened under the aegis of Orbis Scientiae 1977. The title "Deeper Pathways in High Energy Physics" was adopted to indicate either further penetration into the nature of the structure of the elementary particle or the deepening of the continuously trodden path that gets gradually deeper and deeper, evolving into a trench. In the latter instance, the visibility of the real nature of elementary particles may be getting dimmer and dimmer. It is hoped that some of the papers in these proceedings do, indeed, contain further revelations on the "deeper" nature of elementary particles. We must not be overly charmed with "charm" even if it may fit the data of the current generation of e+ and e experiments. It would be much less than prophetic to say that a complete and totally satisfactory theory com~ising the entire physical reality is yet to be discovered, and there is presumably no paper of that kind in these proceedings. Despite this short coming, the editors do not wish to hide their admiration for the caliber of the papers contributed by the participants of Orbis Scientiae 1977. Appreciation is extended to Mrs. Helga S. Billings, Mrs. Elva Brady, and Ms. Yvonne L. Leber for their skillful typing of the proceedings, which they have performed with great enthusiasm and dedication. Orbis Scientiae 1977 received some support from the Energy Research and Development Administration.

This volume contains the greater part of the papers submitted to the High Energy Physics portion of the 1983 Orbis Scientiae, then dedicated to the eightieth year of Professor P. A. M. Dirac. Before the vol,ume could be published, Professor Dirac passed away on October 20, 1984, thereby changing the dedication of this volume, and its companion, on Information Processing in Biology, to his everlasting memory. Since 1969, Professor Dirac had given the opening address at each of these conferences. He was unable to prepare a manuscript of his last paper in 1983. His impact on science already has been enormous. The consequences of his thought and work for future developments are incalculable. Regrettably, Professor Dirac's last appearance at this series of conferences, begun in 1964 as the Coral Gables Conference on Symmetry Principles at High Energy, coincided with the twentieth, and the last of these. The work and expense involved in organizing them and preparing the proceedings have corne to far exceed the physical capabilities and the support received by the Center for Theoretical Studies for this program. The delayed appearance of these proceedings, for which the editors humbly apologize, is a manifestation of the inadequate support. On the other hand, the organizers and editors thank the many distinguished participants who, over the years, made these meetings exciting and productive arenas for the dissemination of ideas in high energy physics and related fields.

Paul Dirac, who died in 1984, was without question one of the greatest physicists of the twentieth century. His revolutionary contribution to modern quantum theory is remembered for its insight and creativity. He is especially famous for his prediction of the magnetic moment and spin of the electron and for the existence of antiparticles. He was awarded the Nobel Prize for physics in 1933 at the age of 31. In this memorial volume, 24 of Dirac's friends, colleagues and contemporaries remember him with affection. There are chapters describing Dirac's personality, and many anecdotes about the man with a reputation for silence. Other chapters describe Dirac's science and its impact on modern physics.

The editors are pleased to submit to the readers the state of the art in high energy physics as it appears at the beginning of 1978. Appreciation is extended to Mrs. Helga S. Billings for her assistance with the conference and for her skillful typing of the proceedings which was done with great enthusiasm and dedication. Also, appreciation is extended to Dr. Osman Kadiro~u for his assistance with the proceedings this year. Orbis Scientiae 1978 received some support from the Department of Energy.

In August 1978 a group of 80 physicists from 51 laboratories of 15 countries met in Erice to attend the 16th Course of the International School of Subnuclear Physics. The countries represented at the School were: Austria, Denmark, Federal Republic of Germany, Finland, France, Israel, Italy, the Netherlands, Sweden, Switzerland, South Africa, Turkey, the United Kingdom, The United States of America, and Yugoslavia. The School was sponsored by the Italian Ministry of Public Education (MPI) , the Italian Ministry of Scientific and Technological Research (MRSI) , the North Atlantic Treaty Organization (NATO), the Sicilian Regional Government, and the Weizmann Institute of Science. As usual, the Course was devoted to a review of the most out standing problems and results in Subnuclear Physics, with particular emphasis on the new aspects; there were mainly two: supersymmetry and electroweak interactions. In his famous lecture at Erice in 1967, Sid Coleman reviewed "All possible symmetries of the S matrix. " All but one, namely that which tells you: if you have a fermion you must have a boson. This is super symmetry , and this produces the superspace, i. e. an entity which has not only the Einstein-"bosonic" coordinates, but also "fermionic" coordinates. From superspace we get supergravity; and this means that one day we should be able to detect not only the graviton (with spin 2) but also the gravitino (spin 3/2). If we add "flavour", "colour", and "family" as other intrinsic degrees of freedom, we get extended supergravity.
