Who are we, who is each one of us if not a combinatoria of experiences, information, books we have read, things we have imagined? Each life is an encyclopedia, a library, an inventory of objects, a series of styles, and everything can be constantly shuffled and reordered in every way conceivable.
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.
Jose Ortega y Gasset
