Linear temporal logic is an established discipline. It is, for example, used to test safety-critical systems, such as aeroplane flight controls. The main difference between computer programs based on linear temporal logic and those using other sorts of programming language is that the former describe how the world ought to be, whereas the latter list specific instructions for the computer to carry out in order to achieve a particular end. The former say something like: “If you need milk, you ought eventually to arrive at the shop.” The latter might say: “Check the refrigerator. If there is no milk, get in your car. Start driving. Turn left at the corner. Park. Walk into the shop.”
