Boltzmann... felt that all that we were really doing when we stated physical laws was using a series of linguistic representations of reality. To relate force and mass, as Newton had done in his laws of motion, was to relate labels in such a way that we could use the relations for predictive purposes. To read anything more into the terms force and mass was to presume more than we can know.ludwig boltzmann

Social science and humanities … have a mutual contempt for one another, the former looking down on the latter as unscientific, the latter regarding the former as philistine. … The difference comes down to the fact that social science really wants to be predictive, meaning that man is predictable, while the humanities say that he is not.Allan Bloom
