"Rudolf Steiner's perspectives on technology are manifold and prophetic. He not only critiqued the technology of his day, but foretold new forms of technology that would inevitably arise, technologies that would be connected to the makers' very attitudes of soul, either the good or bad within them--in other words, their deepest motivations. How we, as evolving human beings, approach technology and its development will be instrumental in determining how ultimately human evolution will turn out. Our future as human beings and the future of technology are intimately connected." --Gary LambIlluminating, compelling, challenging, at times staggering in its breadth, A Road to Sacred Creation is above all the definitive text for gaining a hold on Rudolf Steiner's nuanced perspectives on technology. Charting both an inner and outer course--part pilgrimage toward greater perception and knowledge, part dramatic, unfolding plot line of the future of humans and machines, the metaphoric "road" of the title is exactly where humanity finds itself today, though the exact route and destination are still to be determined. The map is not yet drawn, but here is a beginning.Taken together, the relevant concepts, ideas, and insights of Steiner--deftly brought into sequence and dialogue as the editor has done in this book--reveal how the work to arrive at a more spiritually imbued technological future not only involves all domains and fields of spiritual science and anthroposophic work, but has its origins in the very core of our being, fundamentally entwined with our moral progress toward freedom and selfless love.

For fans of Oliver Sacks and Henry Marsh, a glimpse into the fascinating world of modern neurology by a leading expert in the field.As a trainee doctor, A. J. Lees was enthralled by his mentors: esteemed neurologists who combined the precision of mathematicians, the scrupulosity of entomologists, and the solemnity of undertakers in their diagnoses and treatments. For them, there was no such thing as an unexplained symptom or psychosomatic problem—no difficult cases, just interesting ones—and it was only a matter of time before all disorders of the brain would be understood in terms of anatomical, electrical, and chemical connections.Today, this kind of “holistic neurology” is on the brink of extinction as a slavish adherence to protocols and algorithms—plus a worship of machines—runs the risk of destroying the key foundational clinical skills of listening, observation, and imagination that have been at the heart of the discipline for more than 150 years.In this series of brilliant, insightful, and autobiographical essays, Lees takes us on a kind of Sherlock Holmes tour of neurology, giving the reader insight into—and a defense of—the deep analytical tools that the best neurologists still rely on to diagnose patients: to heal minds and to fix brains.

Brought to you by Penguin. How to handle everything (and everyone) around you when all hell breaks loose, from the international bestselling author of Surrounded by Idiots.Not everything goes the way we want it to - the world or people around us sometimes just spin out of control. Just consider the Covid pandemic for starters. Or how about that mad neighbour you have living next-door to you? Or when work seems to be going down the toilet when the competition keep outsmarting you? So how do you handle everything life throws your way when you'd really prefer to tell everyone to get stuffed?Thomas Erikson will help you turn adversity into success with the help of the behavioural model made famous in Surrounded by Idiots. Starting by reminding us that life is as it is, Erikson helps you see that it is in fact useless to try to control everything happening around you. Instead of protesting when life throws you curveballs, focus instead on how to handle them. Just as you keep the weeds away from the garden to provide space and amazing flowers, you need to find an approach to adversity that works for you and will give you the chance to turn everything into success. Surrounded by Setbacks will help you pinpoint the approach that works for you and will entertain and empower you in equal measure.(c) Thomas Erikson 2021 (P) Penguin Audio 2021

A respected physics professor and author breaks down the great debate over the Big Bang and the continuing quest to understand the fate of the universe. Today, the Big Bang is so entrenched in our understanding of the cosmos that to doubt it would seem crazy. But as Paul Halpern shows in Flashes of Creation, just decades ago its mere mention caused sparks to fly. At the center of the debate were Russian American physicist George Gamow and British astrophysicist Fred Hoyle. Gamow insisted that a fiery explosion explained how the elements of the universe were created. Attacking the idea as half-baked, Hoyle countered that the universe was engaged in a never-ending process of creation. The battle was fierce. In the end, Gamow turned out to be right -- mostly -- and Hoyle, despite his many achievements, is remembered for giving the theory the silliest possible name: "The Big Bang." Halpern captures the brilliance of both thinkers and reminds us that even those proved wrong have much to teach us about boldness, imagination, and the universe itself.
