“Evolution is not just "chance caught on the wing". It is not just a tinkering of the ad hoc, of bricolage, of contraption. It is emergent order honored and honed by selection.”

Stuart Kauffman (1939) American biophysicist

“What humans can't engineer, evolution can.”

Kevin Kelly (1952) American author and editor

Out of Control: The New Biology of Machines, Social Systems and the Economic World (1995)

“I do feel that evolution is being controlled by some sort of divine engineer. I can't help thinking that. And this engineer knows exactly what he or she is doing and why, and where evolution is headed. That’s why we’ve got giraffes and hippopotami and the clap.”

Kurt Vonnegut (1922–2007) American writer

On evolution vs. "intelligent design", interviewed by Jon Stewart, The Daily Show http://www.thedailyshow.com/video/index.jhtml?videoId=18090&title=kurt-vonnegut/ (13 September 2005)

“Religion is essentially pre-scientific. It will pass away. It represents a certain stage of mental development. It has been tinkered with and tinkered with until it is about ready for the scrap heap. The more men know of chemistry and physics and evolution and natural law, the less use they have for supernaturalism. No true scientist can pray. Prayer is unscientific. No evolutionist can believe in the divine origin of anything.”

J. Howard Moore (1862–1916)

"The Source of Religion", International Socialist Review, Vol. 16, Iss. 12, Jun. 1916

“A system needs to be alive and workable even when other people than the first enthusiasts start using it. Reinvention and revolution are enthusiast stuff. Invention and evolution are engineering.”

“The wheel may be one of those cases where the engineering solution can be seen in plain view, yet be unattainable in evolution because it lies [on] the other side of a deep valley, cutting unbridgeably across the massif of Mount Improbable.”

Richard Dawkins (1941) English ethologist, evolutionary biologist and author

[Dawkins, Richard, Richard Dawkins, Why don't animals have wheels?, Sunday Times, November 24, 1996, http://www.simonyi.ox.ac.uk/dawkins/WorldOfDawkins-archive/Dawkins/Work/Articles/1996-11-24wheels.shtml, October 29, 2008, http://web.archive.org/web/20070221073440/http://www.simonyi.ox.ac.uk/dawkins/WorldOfDawkins-archive/Dawkins/Work/Articles/1996-11-24wheels.shtml, February 21, 2007]

“A new concept and a new method were needed. The concept from the engineering standpoint is the evolution of the engineering scientist, i. e., the scientific generalist who maintains a broad outlook. The method is that of the team approach. On large-scale-system problems, teams of scientists and engineers, generalists as well as specialists, exert their joint efforts to find a solution and physically realize it.
We are led to the concept of the system-design team, a small group of engineers or scientists, to lead a large project and organize the system effort. Such men have been variously called engineering scientists, system engineers, system analysts, or large-scale-system designers. The technique has been variously called the systems approach or the team development method. It is toward this man and his teammates that these discussions are directed. With the realization that not enough can be learned in all the required fields to make him a specialist, enough is introduced to make him aware of the language and problems of the specialist. This generalist is a new quantity in the engineering world, and his education must be begun.”

Robert E. Machol (1917–1998) American systems engineer

“The switch from 'steam engines' to 'heat engines' signals the transition from engineering practice to theoretical science.”

“The evolution of man is the evolution of his consciousness.”

G. I. Gurdjieff (1866–1949) influential spiritual teacher, Armenian philosopher, composer and writer

In Search of the Miraculous (1949)
Context: In speaking of evolution it is necessary to understand from the outset that no mechanical evolution is possible. The evolution of man is the evolution of his consciousness.

“Evolution is a tinkerer, not an engineer.”
