Dear Professors Stuckey and Silberstein,
My limited familiarity with the technical difficulties of quantum gravity made for me difficult to read your essay, but the effort was highly rewarded. Great work! Because of the relational, acausal and adynamical approach, combined with the self-consistency criterion, your work qualifies, in my humble opinion, as one of the main research programs in quantum gravity. Congratulations!
Best wishes,
Cristi Stoica
