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:
“There is no philosophy without the art of ignoring objections.”
—Joseph De Maistre (1753–1821)
“Philosophy can be compared to some powders that are so corrosive that, after they have eaten away the infected flesh of a wound, they then devour the living flesh, rot the bones, and penetrate to the very marrow. Philosophy at first refutes errors. But if it is not stopped at this point, it goes on to attack truths. And when it is left on its own, it goes so far that it no longer knows where it is and can find no stopping place.”
—Pierre Bayle (1647–1706)
“The late Président de Montesquieu told me that he knew how to be blind—he had been so for such a long time—but I swear that I do not know how to be deaf: I cannot get used to it, and I am as humiliated and distressed by it today as I was during the first week. No philosophy in the world can palliate deafness.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
