Aldous Huxley is known as the writer of the 1932 novel Brave New World and the author of the essays Perception in 1954 and Heaven and Hell in 1956. In the essay, he described his experience with mescaline, where he swallowed four tenths of a gram dissolved in half a glass of water. He expected the drug to let him into an inner world similar to William Blake's description. Huxley believed that psychedelics reduce the brain's effectiveness in focusing on life's problems and open the mind. He quoted Blake: "If the doors of perception were cleansed, all would appear infinite." These ideas inspired the title of his book The Doors of Perception.
