“Simpler theories may be more convenient to work with, but they are not intrinsically more probable than complex ones.”

— Samir Okasha

“..humans love complexity of thought. This they pursue on the totally baseless assumption that complexity indicates profundity or truth.”

— Walter Martin

“True complexity can only be understood through history, not by looking at the present state of some seemingly complicated construct.”

— E.M. Foner

“You can't learn what you're unable to understand but a theory is infeasible until you won't need it.”

— Robin Sacredfire

“Predictability is not how things will go, but how they can go.”

— Raheel Farooq

“You can't learn what you can't understand but any theory is infeasible until you don't need it.”

— Robin Sacredfire

Theory, from whatever source, is not perfect until it is reduced to practice.

— Hosea Ballou

“systems theory or, as some people might call it, complexity theory? The simplest explanation is that it is the study of interactions.”

— Rich Jolly

“and I think (like you, by the way) that theory cannot be fabricated out of the results of observation, but that it can only…

— Albert Einstein

[The infinitely small] neither have nor can have theory; it is a dangerous instrument in the hands of beginners [ ... ] anticipating, for…

“By any objective standard, the theory of computational complexity ranks as one of the greatest intellectual achievements of humankind -- along with fire, the…

“It’s a simple complex system. That’s the technical name for it. Because it’s simple, it’s prone to cascades, and because it’s complex, you can’t…
