The Joyous Cosomology is one of the most powerful and at the same time fun books I've ever read. It is unfortunate that it is out of print because it has much to show readers concerning the imaginative construction and deconstruction of this universe. This is perhaps Watts' most direct and creative work and it has the potential to open up many doors in the readers mind. The photography in the book is a wonderful addition and works well to spark the imagination into re-creating our perceptions of reality. My best friend let me borrow 'The Joyous Cosmology' and I read it in 2 hours. An intellegent perspective of such things was very interesting to read because most of the time when you hear about Acid, Mescaline, and shrooms, all you hear is a bunch of incohearent praise with nothing to back it up. With a scientific understanding of it, I would feel a lot safer doing such things. A super book!
