The only thing that interests the physicist is finding out on what assumptions a framework of things can be constructed which will enable us to know how to use them mechanically. Physics, as I have said on another occasion, is the technique of techniques and the ars combinatoria for fabricating machines. It is a knowledge which has scarcely anything to do with comprehension.
José Ortega y Gasset
