“Simple rules can have complex consequences. This simple rule has such a wealth of implications that it is worth examining in detail. It is the far from self-evident guiding principle of reductionism and of most modern investigations into cosmic complexity. Reductionism will not be truly successful until physicists and cosmologists demonstrate that the large-scale phenomena of the world arise from fundamental physics alone. This lofty goal is still out of reach. There is uncertainty not only in how physics generates the structures of our world but also in what the truly fundamental rules of physics are.”

“The love of complexity without reductionism makes art; the love of complexity with reductionism makes science.”

Edward O. Wilson (1929) American biologist

“[A] skyhook is … an exception to the principle that all design, and apparent design, is ultimately the result of mindless, motiveless mechanicity. A crane, in contrast, is a subprocess or special feature of a design process that can be demonstrated to permit the local speeding up of the basic, slow process of natural selection, and that can be demonstrated to be itself the predictable (or retroactively explicable) product of the basic process. … [T]he physicist Steven Weinberg, in Dreams of a Final Theory (1992) … distinguishes between uncompromising reductionism (a bad thing) and compromising reductionism (which he ringingly endorses). Here is my own version. We must distinguish reductionism, which is in general a good thing, from greedy reductionism, which is not. The difference, in the context of Darwin's theory, is simple: greedy reductionists think that everything can be explained without cranes; good reductionists think that everything can be explained without skyhooks.”

“Although the behavior that emerges is complex, the rules that guide it are necessarily simple. In fact, it is their simplicity that creates the freedom to behave in complicated adaptive, and surprising ways.”

“Science gets most of its information by the process of reductionism, exploring the details, then the details of the details, until all the smallest bits of the structure, or the smallest parts of the mechanism, are laid out for counting and scrutiny. Only when this is done can the investigation be extended to encompass the whole organism or the entire system. So we say.
Sometimes it seems that we take a loss, working this way.”

Lewis Thomas (1913–1993) American physician, poet and educator

“We struggle to manage complexity every day. We follow intricate diets to lose weight, juggle multiple remotes to operate our home entertainment systems, face proliferating data at the office, and hack through thickets of regulation at tax time. But complexity isn’t destiny. Sull and Eisenhardt argue there’s a better way: By developing a few simple yet effective rules, you can tackle even the most complex problems.
Simple rules are a hands-on tool to achieve some of our most pressing personal and professional objectives, from overcoming insomnia to becoming a better manager or a smarter investor. Simple rules can help solve some of our most urgent social challenges from setting interest rates at the Federal Reserve to protecting endangered marine wildlife along California’s coast.”

“When puzzled, it never hurts to read the primary documents—a rather simple and self-evident principle that has, nonetheless, completely disappeared from large sectors of the American experience.”

“But how does it come about, step by step, that some complex Systems actually function? This question, to which we as students of General Systemantics attach the highest importance, has not yet yielded to intensive modern methods of investigation and analysis. As of this writing, only a limited and partial breakthrough can be reported, as follows: A COMPLEX SYSTEM THAT WORKS IS INVARIABLY FOUND TO HAVE EVOLVED FROM A SIMPLE SYSTEM THAT WORKED”

“The notion of "intricate and beautiful complexities" is almost an oxymoron. Unix programmers vie with each other for "simple and beautiful" honors — a point that's implicit in these rules, but is well worth making overt.”

“All propaganda or popularization involves a putting of the complex into the simple, but such a move is instantly deconstructive. For if the complex can be put into the simple, then it cannot be as complex as it seemed in the first place; and if the simple can be an adequate medium of such complexity, then it cannot after all be as simple as all that.”

Terry Eagleton (1943) British writer, academic and educator

“The ideas need not be complex. Most ideas that are successful are ludicrously simple. Successful ideas generally have the appearance of simplicity because they seem inevitable.”
