Tibetan Buddhist writings frequently state that many of the things we perceive in the world are in fact illusory, as illusory as echoes or mirages. In Twelve Examples of Illusion, Jan Westerhoff offers an engaging look at a dozen illusions--including magic tricks, dreams, rainbows, and reflections in a mirror--showing how these phenomena can give us insight into reality. For instance, he offers a fascinating discussion of optical illusions, such as the wheel of fire (the "wheel" seen when a torch is swung rapidly in a circle), discussing Tibetan explanations of this phenomenon as well as the findings of modern psychology, and significantly clarifying the idea that most phenomena--from chairs to trees--are similar illusions. The book uses a variety of crystal-clear examples drawn from a wide variety of fields, including contemporary philosophy and cognitive science, as well as the history of science, optics, artificial intelligence, geometry, economics, and literary theory. Throughout, Westerhoff makes both Buddhist philosophical ideas and the latest theories of mind and brain come alive for the general reader.

Wake Up Black People: Are Our Communities in Peril? (Dreams Do Come True!) By: DeVere O. Kelley Why are so many of us Black Americans afraid to accept the blame for our own peril? Yes, we have been victims of systemic racism, poverty, wealth inequality, and police violence, but we have also caught ourselves in patterns which contribute to our demise. This book examines the history of not only the societal issues and stereotypes that have plagued our community for decades, but also the self-imposed burdens that continue to hold us back. Black homicide, drug usage, welfare, decrease in life expectancy, black incarceration and health problems are just a few issues covered in this thorough debut work by DeVere O. Kelley. Drawing from his own experiences and from the patterns of history, Kelley offers remedies for the obstacles still facing the Black community.
