I am a scientist, and I have profited from Alexander's efforts to understand very deep problems in complexity.... Nikos Salingaros, Professor of Applied Mathematics, University of Texas.

Book 1 offers straightforward empirical tests that tell us whether any artifact, building, or built environment makes us feel more alive or less. .... Nikos Salingaros, Professor of Applied Mathematics, University of Texas.

First nomination for book of the Century...Warwick Rowell, Builder of Rosneath Farm ecovillage, Australia

I myself won several design competitions after I began to gain some understanding of this material... I am an architect living and working in California.

I have had the opportunity to teach scores of students working on learning and applying the material that forms the basis of these books. . . My experience has been that for those students who were willing to approach this material with an open mind, and with sincere effort, the Nature of Order is a challenging and inspiring work. . .Robert Walsh, PhD student, University of Michigan

One of this world's great literary/philosophical achievements. . .Andrew Ilachinski, physicist, author of Cellular Automata, World Scientific Publishing

Alexander is promoting a mode of dwelling on earth that will reveal and augment life . . . once the problems he is grappling with and the relationship between these and the broader tradition of process thought are understood, it is difficult to imagine the global ecological crisis being addressed successfully without the kind of revolution in architecture that Alexander is striving to bring about. . .Arran Gare, Reader in Philosophy and Cultural Inquiry and Director of the Joseph Needham Centre for Complex Processes Research, Swinburne University, Melbourne, Australia

The genius of CA is that he has found a way of recreating the entire biological framework by looking at phenomena derived purely from artifacts (architecture) and this is why he represents both a revolution (no alternative to this overworked word) in architecture (restoring it as a leading source of models) but also a landmark in the philosophy and history of science, indeed in our own understanding of biology and biological argument. . .Jean Pierre de la Porte, Historian of Science, University of Cape Town, South Africa
