Feynman 'Path Integrals' Or 'Sum Over Histories' Viewed Through Systemic Functional Linguistics

Penrose (2004: 666-7):

The basic idea is a different perspective on the fundamental quantum-mechanical principle of complex linear superposition that we encountered earlier. Here, we think of that principle as applied, not just to specific quantum states, but to entire spacetime histories. We tend to think of these histories as ‘possible alternative classical trajectories’ (in configuration space). The idea is that in the quantum world, instead of there being just one classical ‘reality’, represented by one such trajectory (one history), there is a great complex superposition of all these ‘alternative realities’ (superposed alternative histories).

From the perspective of Systemic Functional Linguistic Theory, a great complex superposition of all these 'alternative realities' represented as ‘possible alternative classical trajectories’ constitutes the potential of the quantum system, whereas the one classical 'reality' represented by one trajectory is one instance of that quantum potential.
