Quantum States vs Classical States Viewed Through Systemic Functional Linguistics

Penrose (2004: 566):

The answer is that almost all ‘large’ quantum states do not resemble classical ones. The most famous such example is Schrödinger’s hypothetical cat, which is in a quantum superposition of being alive and dead. Why do we not actually see things like this at a classical level? This is an aspect of the measurement paradox which will be discussed in Chapters 29 and 30.

From the perspective of Systemic Functional Linguistic Theory, Classical physics provides a model of the actual only, whereas Quantum physics distinguishes between actual and potential, such that the actual are instances of potential. Quantum superposition states are potential states, not actual states, and as such, are not seen 'at the classical level' of actual states.
