In the pursuit of knowledge, Dorion Sagan argues in this dazzlingly eclectic, rigorously crafted, and deliciously witty collection of essays, scientific authoritarianism and philosophical obscurantism are equally formidable obstacles to discovery. As science has become more specialized and more costly, its questing spirit has been constrained by dogma. And philosophy, perhaps the discipline best placed to question orthodoxy, has retreated behind dense theoretical language and arcane topics of learning. Guided by a capacious, democratic view of science inspired by the examples set by his late parents--Carl Sagan, who popularized the study of the cosmos, and Lynn Margulis, an evolutionary biologist who repeatedly clashed with the scientific establishment--Sagan draws on classical and contemporary philosophy to intervene provocatively in often-charged debates on thermodynamics, linear and nonlinear time, purpose, ethics, the links between language and psychedelic drugs, the search for extraterrestrial intelligence, and the occupation of the human body by microbial others. Informed by a countercultural sensibility, a deep engagement with speculative thought, and a hardheaded scientific skepticism, he advances controversial positions on such seemingly sacrosanct subjects as evolution and entropy. At the same time, he creatively considers a wide range of thinkers, from Socrates to Bataille and Descartes to von Uexkull, to reflect on sex, biopolitics, and the free will of Kermit the Frog. Refreshingly nonconformist and polemically incisive, "Cosmic Apprentice" challenges readers to reject both dogma and cliche and instead recover the intellectual spirit of adventure that should--and can once again--animate both science and philosophy.

In a thought-provoking, humorous, and engaging style, Dorion Sagan combines philosophy, science, and an understanding of illusion to probe the deep questions of existence. Operating on the precept that the universe is far weirder than we might imagine, Sagan-- son of acclaimed scientists Carl Sagan and Lynn Margulis--uses his knowledge of philosophy, science, sleight-of-hand magic, and the fantastical writings of Philip K. Dick to explore some of the deepest questions we face on Earth. He provides fresh insights as to why we are here, the nature of technology, the prognosis for humanity, the living nature of our planet, and a reasoned explanation to why our universe is probably just one of an infinite number. Sagan also provides answers to twelve pressing questions: Why does life exist? Why do we drink water? Can we save the Earth from global warming? Are human beings central and special? Is it possible that we've arisen by pure chance? Is the Earth an organism? Are we part of its exo-brain? If it is alive, can it reproduce? Can the universe? What does the future hold in store for us? Does God exist? What is the nature of ultimate reality? Notes from the Holocene is a prime example of the writing coming from a new generation of scientific writers. It will inspire readers to think for themselves while leaving them chuckling with tongue-in-cheek anecdotes--a rare combination that Sagan delivers with ease. And yes, as geneticist J.B.S. Haldane says, "the universe is not only stranger than we imagine, but stranger than we can imagine."

Earth as a cosmic seed is a biosphere. This book is about the concentric layers of experience at the Earth's surface, and the way the past gets tangled up in the present.
