to parents, and children My sincere thanks to Adam Tetlow, Richard Henry, Daud Sutton, and John Martineau for their painstaking assistance in the design and editing of this little book, and also to my many tutors in these profound quantities, particularly Professor Keith Critchlow and John Michell. Additional thanks to Sally Pucill, Haifa Khawaja, and Delfina Bottesini. Thanks particularly to Jim Baldwin for getting the ball rolling. The Tao gives birth to the One, the One gives birth to the Two, the Two gives birth to the Three, the Three gives birth to the Ten Thousand Things.
