Are plants intelligent? Can they solve problems, communicate, and navigate their surroundings? Or are they passive, incapable of independent action or social behavior? Philosophers and scientists have pondered these questions since ancient Greece, most often concluding that plants are unthinking and inert: they are too silent, too sedentary - just too different from us. Yet discoveries over the past 50 years have challenged these ideas, shedding new light on the extraordinary capabilities and complex interior lives of plants.

Set in Mexico City during the early 50s, Queer follows William Lee's hopeless pursuit of desire from bar to bar in the American expatriate scene. As Lee breaks down, the trademark Burroughsian voice emerges; a maniacal mix of self-lacerating humor and the Ugly American at his ugliest. Burroughs' only realist love story, Queer is a haunting tale of possession and exorcism.

US psychologist Abraham Maslow’s A Theory of Human Motivation is a classic of psychological research that helped change the field for good. Like many field-changing thinkers, Maslow was not just a talented researcher, he was also a creative thinker - able to see things from a new perspective and show them in a different light. He studied what he called exemplary people such as Albert Einstein, Jane Addams, Eleanor Roosevelt, and Frederick Douglass rather than mentally ill or neurotic people.

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

Here, anthropologist David Graeber presents a stunning reversal of conventional wisdom: He shows that before there was money, there was debt. For more than 5,000 years, since the beginnings of the first agrarian empires, humans have used elaborate credit systems to buy and sell goods - that is, long before the invention of coins or cash. It is in this era, Graeber argues, that we also first encounter a society divided into debtors and creditors.
