Institut Henri Poincaré, 11 rue P. et M. Curie, 75005, Paris, France aut Is there a reality out there? [Elektronische Daten] [O. Costa de Beauregard] Joseph Bertrand's 1888 evidencing that assignment of a probability depends upon what one chooses to know or not and to control or not, congruent with Grad's 1961 evidencing that statistical entropy depends upon what one deems relevant or not in formalization and measurement, radically undermine common sense realism; mean values are symbols, but symbols of what? For that very reason, recent clever conceptualizations of the quantum measurement process via partial tracing do not restore realism: How could deliberate ignorance generate a reality? Beyond this, Born's and Jordan's quantal wavelike probability calculus, entailing algebraic nonseparability and spacetime nonlocality, blurs "reality” still more radically. Thus information stands out as the master word, with its two reciprocal aspects: knowledge and organization.
