If we accept the short and sweet "Programming as Theory Building (1985)", by Peter Naur, you land on Einstein's (alleged) maxim:
“Everything should be made as simple as possible, but not simpler.”
Or, more fully [1]:
“It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.”
