“The function of good software is to make the complex appear to be simple.”

“The complexity of software is an essential property, not an accidental one. Hence, descriptions of a software entity that abstract away its complexity often abstracts away its essence.”

“Life is not supposed to make things complex. It is to unwind things, by giving simple answers to simple questions.”

“The World is a very complex system. It is easy to have too simple a view of it, and it is easy to do harm and to make things worse under the impulse to do good and make things better.”

“Any darn fool can make something complex; it takes a genius to make something simple.”

“Every software system needs to have a simple yet powerful organizational philosophy (think of it as the software equivalent of a sound bite that describes the system's architecture)… [A] step in [the] development process is to articulate this architectural framework, so that we might have a stable foundation upon which to evolve the system's function points.”

“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.”

“Complexity is your enemy. Any fool can make something complicated. It is hard to make something simple.”

“Life is not complex. We are complex. Life is simple, and the simple thing is the right thing.”

“Economic principles underlie the overall structure of the software lifecycle, and its primary refinements of prototyping, incremental development, and advancemanship. The primary economic driver of the life-cycle structure is the significantly increasing cost of making a software change or fixing a software problem, as a function of the phase in which the change or fix is made.”
