The idea that human history is approaching a "singularity" - that ordinary humans will someday be overtaken by artificially intelligent machines or cognitively enhanced biological intelligence, or both - has moved from the realm of science fiction to serious debate. Some singularity theorists predict that if the field of artificial intelligence (AI) continues to develop at its current dizzying rate, the singularity could come about in the middle of the present century.

Vision, hearing, taste, smell, and touch are what we rely on to perceive the reality of our world. Our five senses are the conduits that bring us the scent of a freshly brewed cup of coffee or the notes of a favorite song suddenly playing on the radio. But are they really that reliable? The Man Who Tasted Words shows that what we perceive to be absolute truths of the world around us is actually a complex internal reconstruction by our minds and nervous systems.

With compassionate stories of his patients and their conditions, Dr. Leschziner illustrates the neuroscience behind our sleeping minds, revealing the many biological and psychological factors necessary in getting the rest that will not only maintain our physical and mental health, but improve our cognitive abilities and overall happiness.

What good are the arts? Why should we care about the past? For millennia, humanity has sought to understand and transmit to future generations not just the "know-how" of life, but the "know-why"—the meaning and purpose of our existence, as expressed in art, architecture, religion, and philosophy.

In Culture, acclaimed author, professor, and public intellectual Martin Puchner takes us on a breakneck tour through pivotal moments in world history.

Soon Taylor's music exploded, and he found himself rich, wanted, and on the road. His new and ever-more-extreme lifestyle had an unexpected effect, however; for the first time, he began to actively think about what it meant to sin.
