From one of America’s most celebrated poets, Nikki Giovanni, comes this poignant collection of poetry that celebrates the simple pleasures of everyday life and the bonds we share with those closest to us. “This slim volume delights on every page. There are stories, imaginings, whimsy, and startling images which prove the poet’s power and her command of language . . . Anyone with a love of language will be delighted with this book and the continuing publication of America’s treasured poet.”—San Francisco Book Review The poetry of Nikki Giovanni has spurred movements and inspired songs, turned hearts and informed generations. She's been hailed as a healer and as a national treasure. But Giovanni's heart resides in the everyday, where family and lovers gather, friends commune, and those no longer with us are remembered. And at every gathering there is food—food as sustenance, food as aphrodisiac, food as memory. A pot of beans is flavored with her mother's sighs—this sigh part cardamom, that one the essence of clove; a lover requests a banquet as an affirmation of ongoing passion; homage is paid to the most time-honored appetizer: soup. With Chasing Utopia, Giovanni demands that the prosaic—flowers, birdsong, winter—be seen as poetic, and reaffirms once again why she is as energetic, "remarkable" (Gwendolyn Brooks), "wonderful" (Marian Wright Edelman),"outspoken, prolific, energetic" (New York Times), and relevant as ever.

This is an essential book for everyone who wants to write clearly about any subject and use writing as a means of learning.

The majority of the world's population is religious or believes in supernatural phenomena. In the United States, nine out of every ten adults believe in God, and a recent Gallup poll found that about three out of four Americans believe in some form of telepathy, ghosts, or past lives. Where does such supernatural thinking come fromAre we indoctrinated by our parents, churches, and media, or do such beliefs originate somewhere elseIn SuperSense, award-winning cognitive scientist Bruce M. Hood reveals the science behind our beliefs in the supernatural. Superstitions are common. Many of us cross our fingers, knock on wood, step around black cats, and avoid walking under ladders. John McEnroe refused to step on the white lines of a tennis court between points. Wade Boggs insisted on eating a chicken dinner before every Boston Red Sox game. President Barack Obama played a game of basketball the morning of his victory in the Iowa primary and continued the tradition on every subsequent election day.Supernatural thinking includes loftier beliefs as well, such as the sentimental value we place on photos of loved ones, wedding rings, and teddy bears. It also includes spiritual beliefs and the hope for an afterlife. But in this modern, scientific age, why do we hold on to these behaviors and beliefs?It turns out that belief in things beyond what is rational or natural is common to humans and appears very early in childhood. In fact, according to Hood, this "super sense" is something we're born with to develop and is essential to the way we learn to understand the world. We couldn't live without it!Our minds are designed from the very start to think there are unseen patterns, forces, and essences inhabiting the world, and it is unlikely that any effort to get rid of supernatural beliefs, or the superstitious behaviors that accompany them, will be successful. These common beliefs and sacred values are essential in binding us together as a society because they help us to see ourselves connected to each other at a deeper level.
