Philosophy
Computing systems may be modeled in VDM-SL at a higher level of abstraction than is achievable using programming languages, allowing the analysis of designs and identification of key features, including defects, at an early stage of system development. Models that have been validated can be transformed into detailed system designs through a refinement process. The language has a formal semantics, enabling proof of the properties of models to a high level of assurance. It also has an executable subset, so that models may be analyzed by testing and can be executed through graphical user interfaces, so that models can be evaluated by experts who are not necessarily familiar with the modeling language itself.

Famous quotes containing the word philosophy:
“Frankly, I do not like the idea of conversations to define the term “unconditional surrender.” ... The German people can have dinned into their ears what I said in my Christmas Eve speech—in effect, that we have no thought of destroying the German people and that we want them to live through the generations like other European peoples on condition, of course, that they get rid of their present philosophy of conquest.”
—Franklin D. Roosevelt (1882–1945)
“All roads are blocked to a philosophy which reduces everything to the word “no.” To “no” there is only one answer and that is “yes.” Nihilism has no substance. There is no such thing as nothingness, and zero does not exist. Everything is something. Nothing is nothing. Man lives more by affirmation than by bread.”
—Victor Hugo (1802–1885)
“The Greeks, with their truly healthy culture, have once and for all justified philosophy simply by having engaged in it, and having engaged in it more fully than any other people.”
—Friedrich Nietzsche (1844–1900)
