Existence and Other Questions
Selected Works of John Horgan
Does free will exist? Is the Schrödinger Equation True? How does matter make a mind? In his Scientific American column, John Horgan takes a scientific approach to exploring mysteries such as these, and in this eBook, we collect some of his most thought-provoking work on consciousness, quantum mechanics, the science of psychedelic drugs and more.
