Quantum Gravity Viewed Through Systemic Functional Linguistics

 Penrose (2004: 713):

In fact, it seems unavoidable that the realm of quantum gravity (or whatever is the appropriate term) will be entered, so that these expectations of the classical theory will have to be modified in accordance with this. We do not yet know what the correct ‘quantum-gravitational’ theory must be, but these black-hole considerations supply us with an important input; and this input should be guiding us in the appropriate directions in our search for the correct ‘quantum gravity’.

From the perspective of Systemic Functional Linguistic Theory, the search for a 'quantum gravitational' theory is a wild goose chase. Where Quantum Theory is concerned with the instantiation of potential, General Relativity is concerned with the interrelation of (instantiated) mass and spacetime.

The motivation for a 'quantum gravitational' theory is the desire to unify the four forces, but according to General Relativity, gravity is not a force between particles, but a geometrical effect of mass on spacetime.
