Hi Bruno Marchal
Perhaps wrongly, I think of the world of monads as the virtual world.
Virtual means simulated by a computer, in computer science.
It has another meaning in physics, which I have never make complete
sense of, as it is unclear if the sense in classical physics and
quantum physics can be said equivalent.
This might explain your attitude toward QM. The "virtual" concept
in QM is a way of representing the "off mass shell" quantities that do
not exist at all in classical physics. There are many measured effects
what depend on the reality of the "virtual" aspect to be explained
quantitatively. For example http://en.wikipedia.org/wiki/Lamb_shift and
on this virtual effect.
