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:
“It is not easy to make our lives respectable by any course of activity. We must repeatedly withdraw into our shells of thought, like the tortoise, somewhat helplessly; yet there is more than philosophy in that.”
—Henry David Thoreau (1817–1862)
“Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
“The literature of the poor, the feelings of the child, the philosophy of the street, the meaning of household life, are the topics of the time. It is a great stride. It is a sign,—is it not? of new vigor, when the extremities are made active, when currents of warm life run into the hands and the feet.”
—Ralph Waldo Emerson (1803–1882)
