Wilson Literary Science Writing Award Harvard's top astronomer lays out his controversial theory that our solar system was recently visited by advanced alien technology from a distant star. "Provocative and thrilling ... Loeb asks us to think big and to expect the unexpected."--Alan Lightman, New York Times bestselling author of Einstein's Dreams and Searching for Stars on an Island in Maine In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard's top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars--and to think critically about what's out there, no matter how strange it seems.

Why do 70 percent of Americans believe in angels, while others are convinced that they were abducted by aliens? What makes people believe in improbable things when all the evidence points to the contrary? And don't almost all of us, at some time or another, engage in magical thinking? In Six Impossible Things Before Breakfast, evolutionary biologist Lewis Wolpert delves into the important and timely debate over the nature of belief, looking at its psychological foundations to discover just what evolutionary purpose it could serve. Wolpert takes us through all that science can tell us about the beliefs we feel are instinctive. He deftly explores different types of belief those of children, of the religious, and of those suffering from psychiatric disorders and he asks whether it is possible to live without belief, or whether it is a necessary component of a functioning society."

Philosophers have not taken the evolution of human beings seriously enough. If they did, argues Peter Munz, many long standing philosophical problems would be resolved. One of philosophical concequences of biology is that all the knowledge produced in evolution is a priori , i.e., established hypothetically by chance mutation and selective retention, not by observation and intelligent induction. For organisms as embodied theories, selection is natural and for theories as disembodied organisms, it is artificial. Following Popper, the growth of knowledge is seen to be continuous from the amoeba to Einstein'. Philosophical Darwinism throws a whole new light on many contemporary debates. It has damaging implications for cognitive science and artificial intelligence, and questions attempts from within biology to reduce mental events to neural processes. More importantly, it provides a rational postmodern alternative to what the author argues are the unreasonable postmodern fashions of Kuhn, Lyotard and Rorty.

The third volume in a projected four-part series on the evolution of human intelligence, a series acknowledged by opponents and supporters alike as one of the most important recent investigations into the sources and nature of human intelligence. Professor Itzkoff first sets forth the evolutionary facts as a beacon to illuminate his biological theory of variable intelligence. Filling out the evidence from the psychological and brain sciences presented in THE FORM OF MAN and TRIUMPH OF THE INTELLIGENT, he here develops a full-scale model of the mind that more fully explains the relationship between I.Q. and the broader expressions of human intelligence as experienced in daily life. (His model of variable intelligence further delves into the historical consequences of our ancient biological and psychoneurological heritage. Issues such as gender, race, and ethnic variability are treated factually and responsibly, taking into account the full range of empirical evidence available to scholars.) The result is a theory having three complementary bodies of evidence - evolutionary, psychoneurological, and historical - building into a perspective on the factual «why» of human intellectual differences. These differences can best be observed in the richness and diversity of individual personality as well as in the cultures of our world. Itzkoff here takes the first tentative steps toward a biological explanation of the nature and structure of culture. WHY HUMANS VARY IN INTELLIGENCE is an appeal for the rational study of human nature, a plea to allow for further nonideological research into this most crucial area of contemporary concern.

The Form of Man presents a new interpretation, consonant with Darwinian evolutionary theory, recent evidence of human evolution, and the realities of cultural life. The exploration begins with the study of the form of life, traversing the tentative gropings of intelligent organic matter in its long struggle to establish itself as life's major adaptation. Seymour Itzkoff explains how intelligence as an adaptation is the slowest and most complex of life's vehicles to escape the degradation of energy predicted by the second law of thermodynamics. Dr. Itzkoff proposes that two evolutionary processes were keys to shaping human nature along its own particular path. Paedomorphosis (infantilization) explains many of man's unique anthropoid features. Orthoselection (evolution in a straight line) allows us to complete a picture of mankind's rapid catapult in brain size expansion almost into our own day. Both concepts reveal how man could have escaped the close selective honing that would have made him a far more practical creature. The final dramatic moment came with the sudden icy extrusion of a super sapient, Homo sapiens sapiens, sometime after 100,000 B.P. It ransformed the structure of all existing transitional hominids and created the conditions for both the growth of civilization and the paradoxical dilemmas and tragedies in our present polyglot humanity.
