This paper presents an argument for research into the means of altering individual attitudes, values, and communication abilities in the direction of increased social empathy, which, in turn, would produce a more favorable environment for resolving differences and facilitate peaceful negotiations between individuals and nations. It is proposed that prior research with the drug, d-lysergic acid diethylamide (LSD), shows sufficient promise in producing relatively long-lasting changes in the above areas to merit further research. Furthermore, the use of LSD has been demonstrated to be quite safe under supervisory conditions, i.e., the guided “trip.” LSD is also nontoxic and non-addictive. A brief history of psychedelic drugs is provided along with a description of their psychological effects. Some possible modes of action are discussed. LSD and other psychedelics are seen as possible means of tapping mental resources which are not ordinarily available, but which may be of great value to the individual and ultimately to the society. No attempt is made in this paper to discuss how the use of a drug such as LSD might be implemented in international peace negotiations. It is contended, however, that results of previous experiments demonstrate increased tolerance for opposing viewpoints, increased understanding, and increased social empathy. It would be very important, based on the above findings, to explore the potential psychedelic drugs may have in reducing the threat of nuclear war.
