The world fractures into a play of points of view that do not admit of a univocal, global vision. It is a world of perspectives, of manifestations, not of entities with definite properties or unique facts. Properties do not reside in objects, they are bridges between objects. Objects are such only with respect to other objects, they are nodes where

Entanglement is not a dance for two partners, it is a dance for three.

Since measuring P alters X, measuring X first and then P gives different results than measuring P and then X. Hence in mathematics ‘first X and then P’ is necessarily different from ‘first P and then X’.77 This is precisely the property that characterizes matrices: order counts.78 Remember the single new equation introduced by quantum theory? XP –

This is a solution to the puzzle, but it comes at a cost: no universal set of facts exists. There exist facts relative to Beijing, and facts relative to Vienna, and the two do not match. Facts relative to one observer are not facts relative to another. It is a shining example of the relativity of reality. The joint properties of two objects exist

In the first decades of the twentieth century, it is the whole of European culture that no longer thinks we can represent the world in a simple and complete way. The anthropologist Lévi-Strauss understands that to study a culture is to change it; Freud understands that doctors cannot evaluate patients’ minds without affecting them. In Italy,

The discovery of quantum theory, I believe, is the discovery that the properties of any entity are nothing other than the way in which that entity influences others. It exists only through its interactions. Quantum theory is the theory of how things influence each other. And this is the best description of nature that we have.54

Only God can see the two places at the same moment – but God, if She exists, does not tell us what She sees.

What quantum theory describes, then, is the way in which one part of nature manifests itself to any other single part of nature.
