Résumé d’auteur : Only two fundamental assumptions are at work in a device-independent approach: the inputs and the outputs are clearly distinguished; and the connection between them is physical. A philosophy of physics that supports this conception is free of any human element. It describes what the observer is through what the observer does: it operates with strings in finite alphabets. Our framework puts forward a set of conditions for a theory to contain the notions of physical system, local observer and causality; it also shows a natural way to obtain contextuality and probability starting only with the inputs and the outputs.
