When it comes to the phenomenon that is consciousness, there is one point on which scientists, philosophers, and artists all agree: it feels like something to be us. Yet the fact that we have subjective experience of the world remains one of nature’s greatest mysteries. How is it that our mental operations are accompanied by feelings, thoughts, and a sense of self? What would a scientific investigation of our inner life look like, when we have as little distance and perspective on it as fish do of the sea? In A World Appears, Michael Pollan traces the unmapped continent that is consciousness, bringing radically different perspectives—scientific, philosophical, literary, spiritual and psychedelic—to see what each can teach us about this central fact of life.

When neuroscientists began studying consciousness in the early 1990s, they sought to explain how and why three pounds of spongy gray matter could generate a subjective point of view—assuming that the brain is the source of our perceived reality. Pollan takes us to the cutting edge of the field, where scientists are entertaining more radical (and less materialist) theories of consciousness. He introduces us to “plant neurobiologists” searching for the first flicker of consciousness in plants, scientists striving to engineer feelings into AI, and psychologists and novelists seeking to capture the felt experience of our slippery stream of consciousness.

In Pollan’s dazzling exploration of consciousness, he discovers a world far deeper and stranger than our everyday reality. Eye-opening and mind-expanding, A World Appears takes us into the laboratories of our own minds, ultimately showing us how we might make better use of the gift of awareness to more meaningfully connect with the world and our deepest selves.


Michael Pollan is the author of ten books, including This Is Your Mind on Plants, How to Change Your Mind, Cooked, Food Rules, In Defense of Food, The Omnivore’s Dilemma, and The Botany of Desire, all of which were New York Times bestsellers. He is also the author of the audiobook Caffeine. A Guggenheim and Radcliffe Fellow, Pollan has taught writing at the University of California, Berkeley, and at Harvard University. In 2010, Time named him one of the one hundred most influential people in the world.

Louisa Thomas is a staff writer at the New Yorker, where she writes the weekly Sporting Scene column, and a Lecturer in creative writing at Harvard. She is also the author of several books, including Louisa: The Extraordinary Life of Mrs. Adams, a biography of the wife of John Quincy Adams.
