Nature is defined as what the Gauges (Standard Instruments) measure, and Gauges is what Nature measures. When Einstein was asked "what is Time?", He replied "this is what the clock shows." But the definition of Nature "all that we see" is wrong, because we can see a devil (and a sin), who is not natural.
By measuring, instruments change Nature. It's like when you measure blood pressure, the cuff squeezes the arm hard, you worry and the pressure and pulse rise. Observations (pressure measurement apparatus) must be un-changeable by definition Observations, but the Nature changes.
Therefore, Quantum Mechanics is needed as an relation between the Observer and Nature. After all, observations are recorded in the definition of Nature.
Shroedinger's cat: cat is put into a box, where Uranium atom decays and triggers Geiger counter, latter breaks the ampoule with poison and cat dies.
The scientists say, that if we do not open the box, the cat is in limbo state between life and death ("quantum superposition").
But why such a terror? Let's place in the box a PERSON, but we will remove far away an ampoule with poison. If the radioactive material has decayed, then a Geiger counter will work with a 40 percent probability. Due to the fact that the counter is not determined to react, the superposition (decayed -- not decayed) inside the radioactive substance is not disturbed by the observations of the person. Only in case of Geiger reaction, the superposition inside the radioactive substance would be broken. To "measure something", means, that somebody looks at Geiger counter, and latter actually reacts.
Superposition is not measured by instruments, therefore superposition is not a part of Nature. And if so, then the logic of Aristotle (White is not Black and Black is not White) is not violated.
NOTE: the size matters.
Indeed, the smaller the object of Nature, the stronger it is modified by measurements. Thus, the bigger the object, it is less "quantum". Indeed, a bullets in double-slit target are not producing wave-like interference pattern (even when their flights are not observed).
