High Quality Content by WIKIPEDIA articles! Mind at Large is a concept from The Doors of Perception and Heaven and Hell by Aldous Huxley. This philosophy was influenced by the ideas of C. D. Broad. Psychedelic drugs are thought to disable filters which block or suppress signals related to mundane functions from reaching the conscious mind. In this book, Huxley explores the idea that the human mind filters reality, partly because handling the details of all of the impressions and images coming in would be unbearable, partly because it has been taught to do so. He believes that psychotropic drugs can partly remove this filter, which leaves the drug user exposed to Mind at Large. Huxley was administered mescaline, and had an interviewer prompt him to comment on various stimuli around him, such as books and flowers. The conversation was recorded and the book mainly concerns Huxley`s thoughts on what he says in the recordings. He observed that everyday objects lose their functionality and suddenly exist "as such." Space and dimension become irrelevant, and perceptions seem to be enlarged and at times even overwhelming.
