I was turned Onto Doors / Heaven and Hell by myPhilosophy / English Professor. Due to my extended research intodreaming and perception, this was as insightful as they come. This book goes beyond the use of drugs; Identifying with religion, art, philosophies, etc., it Explains That humans tend to be one sided, and are unable to look or percieve normalcy except by looking at things ... normally. It's sad indeed it takes drug use to be able to percieve objects Beyond What They Really Are, yet, Huxley Explains, Compares and vividly Depicts, not only his experience with mescaline and LCD, but how and why people are not able to visualize things in Ways other than They already are, (out-there, in-Here). Huxley writes about experiences and perception When synthesis drugs are being used - rationally, making Huxley a writer, and a "visionary." And he does so with panache.
