When robert g. jahn and brenda j. dunne first embarked on their exotic scholarly journey more than three decades ago, their aspirations were little higher than to attempt replication of some previously asserted anomalous results that might conceivably impact future engineering practice, either negatively or positively, and to pursue those ramifications to some appropriate extent. but as they followed that tortuous research path deeper into its metaphysical forest, it became clear that far more fundamental epistemological issues were at stake, and far stranger phenomenological creatures were on the prowl, than they had originally envisaged, and that a substantially broader range of intellectual and cultural perspectives would be required to pursue that trek productively. this text is their attempt to record some of the tactics developed, experiences encountered, and understanding acquired on this mist-shrouded exploration, in the hope that their preservation in this format will encourage and enable deeper future scholarly penetrations into the ultimate source of reality. "this book is the culmination of one of the most important research projects of the twentieth century. it not only invites us to reassess our worldview, it compels us to do so. some books transform lives. this one may transform a culture."-larry dossey, md, author ofhealing words andthe power of premonitions"princeton university's pear lab, definitively documented in jahn and dunne's masterful book, has consistently challenged one of science's most stubbornly held assumptions</br>that objective reality is completely independent of consciousness. their experimental evidence is persuasive, tantalizing, and ultimately staggering in its implications. orthodox thinkers will protest, but the scientific revolution is charging ahead and this book blazes the trail." -dean radin, author of the conscious universe and entangled minds "this book tells the profound and compelling story of one of the most essential scientific investigations since einstein's reformulation of space and time. jahn's and dunne's bold and heretical research into the inextricable connection between mind and matter demolishes many of our most dearly held scientific premises, redefines what it means to be human, and challenges us to live by an entirely new set of rules." -lynne mctaggart, author of the field, the intention experiment, and the bond robert g. jahn is professor of aerospace sciences and dean emeritus of princeton university's school of engineering and applied science, founder and director of the pear laboratory, and chairman of icrl.brenda j. dunne holds degrees in psychology and the humanities, was the manager of the pear laboratory from its inception in 1979, and is currently president of icrl.
