Rudolf Steiner demonstrates that there are twelve main philosophical standpoints, and that the future of philosophy rests not upon defending one and refuting the others, but in learning to experience the validity of them all.What convinces us of the truth of a certain point of view? Why do we find it difficult to comprehend viewpoints that differ from our own? What are the inner foundations of our knowledge? In these concentrated and aphoristic lectures, Steiner speaks of twelve main philosophical standpoints, and the importance of understanding each of them. An appreciation of the variety of possible world views not only sharpens and makes more flexible our own powers of thinking, but helps us to overcome a narrow-minded one-sidedness, promoting tolerance of other people and their opinions.Steiner goes on to explain how each standpoint is also coloured by a particular 'soul mood', which influences the way we actively pursue knowledge. Several philosophers and their works are characterised in this manner, throwing light on their contributions to human culture. Through such insight into the true nature of human thinking, we are led to understand the quality of cosmic thought and how, in Rudolf Steiner's words, the human being can be seen as a 'thought which is thought by the Hierarchies of the cosmos'.

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history, either. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. Nagel's skepticism is not based on religious belief or on a belief in any definite alternative. In Mind and Cosmos, he does suggest that if the materialist account is wrong, then principles of a different kind may also be at work in the history of nature, principles of the growth of order that are in their logical form teleological rather than mechanistic. In spite of the great achievements of the physical sciences, reductive materialism is a world view ripe for displacement. Nagel shows that to recognize its limits is the first step in looking for alternatives, or at least in being open to their possibility.

In these concentrated and aphoristic lectures, Rudolf Steiner demonstrates that there are twelve main philosophical standpoints, and that fruitful progress in philosophy depends not upon defending one and refuting the others but upon learning to experience the validity of them all. This not only sharpens and makes more flexible our own powers of thinking, but helps us overcome a narrow-minded one-sidedness, promoting understanding of other people and their opinions.

Jo Marchant's book can begin to heal it. For at least 20,000 years, we have led not just an earthly existence but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are—our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost. Our relationship to the stars and planets has moved from one of awe, wonder and superstition to one where technology is king—the cosmos is now explored through data on our screens, not by the naked eye observing the natural world. Indeed, in most countries, modern light pollution obscures much of the night sky from view. Jo Marchant's spellbinding parade of the ways different cultures celebrated the majesty and mysteries of the night sky is a journey to the most awe-inspiring view you can ever see: looking up on a clear dark night. That experience and the thoughts it has engendered have radically shaped human civilization across millennia. The cosmos is the source of our greatest creativity in art, in science, in life. To show us how, Jo Marchant takes us to the Hall of the Bulls in the caves at Lascaux in France, and to the summer solstice at a 5,000-year-old tomb at Newgrange, Ireland. We discover Chumash cosmology and visit medieval monks grappling with the nature of time and Tahitian sailors navigating by the stars. We discover how light reveals the chemical composition of the sun, and we are with Einstein as he works out that space and time are one and the same. A four-billion-year-old meteor inspires a search for extraterrestrial life. The cosmically liberating, summary revelation is that star-gazing made us human.

The acclaimed author of Einstein’s Dreams tackles "big questions like the origin of the universe and the nature of consciousness ... in an entertaining and easily digestible way” (Wall Street Journal) with a collection of meditative essays on the possibilities—and impossibilities—of nothingness and infinity, and how our place in the cosmos falls somewhere in between. Can space be divided into smaller and smaller units, ad infinitum? Does space extend to larger and larger regions, on and on to infinity? Is consciousness reducible to the material brain and its neurons? What was the origin of life, and can biologists create life from scratch in the lab? Physicist and novelist Alan Lightman, whom The Washington Post has called “the poet laureate of science writers,” explores these questions and more—from the anatomy of a smile to the capriciousness of memory to the specialness of life in the universe to what came before the Big Bang. Probable Impossibilities is a deeply engaged consideration of what we know of the universe, of life and the mind, and of things vastly larger and smaller than ourselves.
